Mortality post perioperative CPR climbs with patient frailty
And the frailer that patients were going into surgery, according to their scores on an established frailty index, the greater their adjusted mortality risk at 30 days and the likelier they were to be discharged to a location other than their home.
The findings are based on more than 3,000 patients in an American College of Surgeons (ACS) quality improvement registry who underwent CPR at noncardiac surgery, about one-fourth of whom scored a least 40 on the revised Risk Analysis Index (RAI). The frailty index accounts for the patient’s comorbidities, cognition, functional and nutritional status, and other factors as predictors of postoperative mortality risk.
Such CPR for perioperative cardiac arrest “should not be considered futile just because a patient is frail, but neither should cardiac arrest be considered as ‘reversible’ in this population, as previously thought,” lead author Matthew B. Allen, MD, of Brigham and Women’s Hospital, Boston, said in an interview.
“We know that patients who are frail have higher risk of complications and mortality after surgery, and recent studies have demonstrated that frailty is associated with very poor outcomes following CPR in nonsurgical settings,” said Dr. Allen, an attending physician in the department of anesthesiology, perioperative, and pain medicine at his center.
Although cardiac arrest is typically regarded as being “more reversible” in the setting of surgery and anesthesia than elsewhere in the hospital, he observed, there’s very little data on whether that is indeed the case for frail patients.
The current analysis provides “a heretofore absent base of evidence to guide decision-making regarding CPR in patients with frailty who undergo surgery,” states the report, published in JAMA Network Open.
The 3,058 patients in the analysis, from the ACS National Surgical Quality Improvement database, received CPR for cardiac arrest during or soon after noncardiac surgery. Their mean age was 71 and 44% were women.
Their RAI scores ranged from 14 to 71 and averaged 37.7; one-fourth of the patients had scores of 40 or higher, the study’s threshold for identifying patients as “frail.”
Overall in the cohort, more cardiac arrests occurred during surgeries that entailed low-to-moderate physiologic stress (an Operative Stress Score of 1 to 3) than in the setting of emergency surgery: 67.9% vs. 39.1%, respectively.
During emergency surgeries, a greater proportion of frail than nonfrail patients experienced cardiac arrest, 42% and 38%, respectively. The same relationship was observed during low-to-moderate stress surgeries: 76.6% of frail patients and 64.8% of nonfrail patients. General anesthesia was used in about 93% of procedures for both frail and nonfrail patients, the report states.
The primary endpoint, 30-day mortality, was 58.6% overall, 67.4% in frail patients, and 55.6% for nonfrail patients. Frailty and mortality were positively associated, with an adjusted odds ratio (AOR) of 1.35 (95% confidence interval [CI], 1.11-1.65, P = .003) in multivariate analysis.
Of the cohort’s 1,164 patients who had been admitted from home and survived to discharge, 38.6% were discharged to a destination other than home; the corresponding rates for frail and nonfrail patients were 59.3% and 33.9%, respectively. Frailty and nonhome discharge were positively correlated with an AOR of 1.85 (95% CI, 1.31-2.62, P < .001).
“There is no such thing as a low-risk procedure in patients who are frail,” Dr. Allen said in an interview. “Frail patients should be medically optimized prior to undergoing surgery and anesthesia, and plans should be tailored to patients’ vulnerabilities to reduce the risk of complications and facilitate rapid recognition and treatment when they occur.”
Moreover, he said, management of clinical decompensation in the perioperative period should be a part of the shared decision-making process “to establish a plan aligned with the patients’ priorities whenever possible.”
The current study quantifies risk associated with frailty in the surgical setting, and “this quantification can help providers, patients, and insurers better grasp the growing frailty problem,” Balachundhar Subramaniam, MD, MPH, of Harvard Medical School, Boston, said in an interview.
Universal screening for frailty is “a must in all surgical patients” to help identify those who are high-risk and reduce their chances for perioperative adverse events, said Dr. Subramaniam, who was not involved in the study.
“Prehabilitation with education, nutrition, physical fitness, and psychological support offer the best chance of significantly reducing poor outcomes” in frail patients, he said, along with “continuous education” in the care of frail patients.
University of Colorado surgeon Joseph Cleveland, MD, not part of the current study, said that it “provides a framework for counseling patients” regarding their do-not-resuscitate status.
“We can counsel patients with frailty with this information,” he said, “that if their heart should stop or go into in irregular rhythm, their chances of surviving are not greater than 50% and they have a more than 50% chance of not being discharged home.”
Dr. Allen reported receiving a clinical translational starter grant from Brigham and Women’s Hospital Department of Anesthesiology; disclosures for the other authors are in the original article. Dr. Subramaniam disclosed research funding from Masimo and Merck and serving as an education consultant for Masimo. Dr. Cleveland reported no relevant financial relationships.

Hold Ozempic before surgery to optimize patient safety?
Semaglutide and related drugs for weight loss have co-opted bariatric medicine in recent months. They have also raised serious questions for hospital-based clinicians who wonder whether the drugs may pose risks to surgery patients undergoing anesthesia.
at this point. Official guidance on best practices has not yet caught up to surging popularity of this and other glucagon-like peptide-1 (GLP-1) agonists for weight loss.
Ozempic is indicated for treating type 2 diabetes but also is prescribed off-label for weight loss. Other GLP-1 agents from Novo Nordisk, Wegovy (semaglutide) and Saxenda (liraglutide) injections, are Food and Drug Administration–approved for weight loss. These medications work by decreasing hunger and lowering how much people eat. Semaglutide also is available as a once-daily tablet for type 2 diabetes (Rybelsus).
The American Society of Anesthesiologists (ASA) has been working on guidance on the drugs. “It’s a really hot issue now. We are getting emails from our members looking for guidance,” ASA president Michael Champeau, MD, said in an interview.
But despite the interest in how the medications might affect surgery patients and interact with anesthesia, relatively little evidence exists in the literature beyond case studies. So the society is not issuing official recommendations at this point.
“We’re going to just be calling it ‘guidance’ for right now because of the paucity of the scientific literature,” said Dr. Champeau, adjunct clinical professor of anesthesiology, perioperative, and pain medicine at Stanford (Calif.) University. “It’s probably not going to have words like ‘must; it will probably have words like ‘should’ or ‘should consider.’ “
The ASA guidance could be out in written form soon, Dr. Champeau added.
Meanwhile, whether physicians should advise stopping these medications 24 hours, 48 hours, or up to 2 weeks before surgery remains unknown.
In search of some consensus, John Shields, MD, an orthopedic surgeon at Atrium Health Wake Forest Baptist Davie Medical Center in Bermuda Run, N.C., asked colleagues on #MedTwitter: “Anyone have guidelines for ozempic around time of surgery? – holding med? – how long NPO?”
Because a full stomach can interfere with anesthesia, clinicians often advise people to stop eating and drinking 12-24 hours before elective procedures (NPO). In the case of once-weekly GLP-1 injections, which can slow gastric emptying, the optimal timeframe remains an open question. The main concern is aspiration, where a patient actively vomits while under anesthesia or their stomach contents passively come back up.
Dr. Shields’ Twitter post garnered significant reaction and comments. Within 4 days, the post was retweeted 30 times and received 72 replies and comments. Dr. Shields noted the general consensus was to hold semaglutide for 1-2 weeks before a procedure. Other suggestions included recommending a liquid diet only for 24-48 hours before surgery, recommending an NPO protocol 24-36 hours in advance, or adjusting the weekly injection so the last dose is taken 5-6 days before surgery.
Anesthesiologist Cliff Gevirtz, MD, has encountered only a few surgical patients so far taking a GLP-1 for weight loss. “And thankfully no aspiration,” added Dr. Gevirtz, clinical director of office-based ambulatory anesthesia services at Somnia Anesthesia in Harrison, N.Y.
To minimize risk, some physicians will perform an ultrasound scan to assess the contents of the stomach. If surgery is elective in a patient with a full stomach, the procedure can get postponed. Another option is to proceed with the case but treat the patient as anesthesiologists approach an emergency procedure. To be safe, many will treat the case as if the patient has a full stomach.
Dr. Gevirtz said he would treat the patient as a ‘full stomach’ and perform a rapid sequence induction with cricoid pressure. He would then extubate the patient once laryngeal reflexes return.
A rapid-sequence induction involves giving the medicine that makes a patient go to sleep, giving another medicine that paralyzes them quickly, then inserting a breathing tube – all within about 30 seconds. Cricoid pressure involves pushing on the neck during intubation to try to seal off the top of the esophagus and again minimize the chances of food coming back up.
Giving metoclopramide 30 minutes before surgery is another option, Dr. Gevirtz said. Metoclopramide can hasten the emptying of stomach contents. Administration in advance is important because waiting for the drug to work can prolong time in the operating room.
Is holding semaglutide before surgery a relevant clinical question? “Yes, very much so,” said Ronnie Fass, MD, division director of gastroenterology and hepatology and the medical director of the Digestive Health Center at The MetroHealth System in Cleveland.
Dr. Fass recommended different strategies based on the semaglutide indication. Currently, clinicians at MetroHealth instruct patients to discontinue diabetic medications the day of surgery. For those who take semaglutide for diabetes, and because the medication is taken once a week, “there is growing discussion among surgeons that the medication should not be stopped prior to surgery. This is to ensure that patients’ diabetes is well controlled before and during surgery,” Dr. Fass said.
In patients taking semaglutide for weight loss only, “there is no clear answer at this point,” he said.
Dr. Fass said the question is complicated by the fact that the medication is taken once a week. “It brings up important questions about the use of the medication during surgery, which may increase the likelihood of side effects in general and for certain types of surgery. Personally, if a patient is taking [semaglutide] for weight loss only, I would consider stopping the medication before surgery.”
The ASA was able to act quickly because it already had an expert task force review how long people should fast before surgery last year – before the explosion in popularity of the GLP-1 agonists.
Although it is still a work in progress, Dr. Champeau offered “a peek” at the recommendations. “The guidance is going to look at how far in advance the drugs should be stopped, rather than looking at making people fast even longer” before surgery, he said. “There’s just no data on that latter question.”

A doctor must go to extremes to save a choking victim
Some time ago I was invited to join a bipartisan congressional task force on valley fever, also known as coccidioidomycosis. A large and diverse crowd attended the task force’s first meeting in Bakersfield, Calif. – a meeting for everyone: the medical profession, the public, it even included veterinarians.
The whole thing was a resounding success. Francis Collins was there, the just-retired director of the NIH. Tom Frieden, then-director of the Centers for Disease Control and Prevention was there, as were several congresspeople and also my college roommate, a retired Navy medical corps captain. I was enjoying it.
Afterward, we had a banquet dinner at a restaurant in downtown Bakersfield. One of the people there was a woman I knew well – her husband was a physician friend. The restaurant served steak and salmon, and this woman made the mistake of ordering the steak.
Not long after the entrees were served, I heard a commotion at the table just behind me. I turned around and saw that woman in distress. A piece of steak had wedged in her trachea and she couldn’t breathe.
Almost immediately, the chef showed up. I don’t know how he got there. The chef at this restaurant was a big guy. I mean, probably 6 feet, 5 inches tall and 275 pounds. He tried the Heimlich maneuver. It didn’t work.
At that point, I jumped up. I thought, “Well, maybe I know how to do this better than him.” Probably not, actually. I tried and couldn’t make it work either. So I knew we were going to have to do something.
Paul Krogstad, my friend and research partner who is a pediatric infectious disease physician, stepped up and tried to put his finger in her throat and dig it out. He couldn’t get it. The patient had lost consciousness.
So, I’m thinking, okay, there’s really only one choice. You have to get an airway surgically.
I said, “We have to put her down on the floor.” And then I said, “Knife!”
I was looking at the steak knives on the table and they weren’t to my liking for doing a procedure. My college roommate – the retired Navy man – whipped out this very good pocketknife.
I had never done this in my life.
While I was making the incision, somebody gave Paul a ballpoint pen and he broke it into pieces to make a tracheostomy tube. Once I’d made the little incision, I put the tube in. She wasn’t breathing, but she still had a pulse.
I leaned forward and blew into the tube and inflated her lungs. I could see her lungs balloon up. It was a nice feeling, because I knew I was clearly in the right place.
I can’t quite explain it, but while I was doing this, I was enormously calm and totally focused. I knew there was a crowd of people around me, all looking at me, but I wasn’t conscious of that.
It was really just the four of us: Paul and Tom and me and our patient. Those were the only people that I was really cognizant of. Paul and Tom were not panic stricken at all. I remember somebody shouting, “We have to start CPR!” and Frieden said, “No. We don’t.”
Moments later, she woke up, sat up, coughed, and shot the piece of steak across the room.
She was breathing on her own, but we still taped that tube into place. Somebody had already summoned an ambulance; they were there not very long after we completed this procedure. I got in the ambulance with her and we rode over to the emergency room at Mercy Truxtun.
She was stable and doing okay. I sat with her until a thoracic surgeon showed up. He checked out the situation and decided we didn’t need that tube and took it out. I didn’t want to take that out until I had a surgeon there who could do a formal tracheostomy.
They kept her in the hospital for 3 or 4 days. Now, this woman had always had difficulties swallowing, so steak may not have been the best choice. She still had trouble swallowing afterward but recovered.
I’ve known her and her husband a long time, so it was certainly rewarding to be able to provide this service. Years later, though, when her husband died, I spoke at his funeral. When she was speaking to the gathering, she said, “And oh, by the way, Royce, thanks for saving my life.”
That surprised me. I didn’t think we were going to go there.
I’d never tried to practice medicine “at the roadside” before. But that’s part of the career.

Appendicitis more often missed in patients who are Black
This phenomenon, first described in children, occurs in adults as well, according to a study published in JAMA Surgery.
Some hospitals fare better than others: Those with more diverse patient populations were less likely to have missed the diagnosis, the researchers found.
“We don’t think the amount of melanin in your skin predicts how you present with appendicitis,” said Jonathan Carter, MD, professor of surgery at the University of California, San Francisco. “There’s no biological explanation,” Dr. Carter, who wrote an invited commentary on the research, said in an interview. “It’s really what’s going on in the social environment of those emergency rooms.”
For the study, Anne Stey, MD, assistant professor of surgery at Northwestern University in Chicago and her colleagues analyzed data from more than 80,000 men and women in four states – Florida, Maryland, New York, and Wisconsin – who underwent appendectomy in 2016-2017.
They identified those who had been seen for abdominal complaints at a hospital in the week before surgery but did not receive a diagnosis of appendicitis at that time, indicating a missed opportunity to intervene sooner.
Among Black patients, the proportion who had experienced this type of delay was 3.6%, whereas for White patients, it was 2.5%. For Hispanic patients, the share was 2.4%, while for Asian or Pacific Islander patients, the figure was 1.5%.
An analysis that controlled for patient and hospital variables found that among non-Hispanic Black patients, the rate of delayed diagnosis was 1.41 times higher than for non-Hispanic White patients (95% confidence interval, 1.21-1.63).
Other patient factors associated with delayed diagnosis included female sex, comorbidities, and living in a low-income zip code.
A key factor was where patients sought care. A delayed diagnosis of appendicitis was 3.51 times more likely for patients who went to hospitals where most patients are insured by Medicaid. Prior research has shown that “safety-net hospitals have fewer resources and may provide lower-quality care than hospitals with a larger private payer population,” Dr. Stey’s group writes.
On the other hand, going to a hospital with a more diverse patient population reduced the odds of a delayed diagnosis.
“Patients presenting to hospitals with a greater than 50% Black and Hispanic population were 0.73 (95% CI, 0.59-0.91) times less likely to have a delayed diagnosis, compared with patients presenting to hospitals with a less than 25% Black and Hispanic population,” the researchers report.
In the 30 days after discharge following appendectomy, Black patients returned to the hospital at a higher rate than White patients did (17.5% vs. 11.4%), indicating worse outcomes.
“Delayed diagnosis may account for some of the racial and ethnic disparities observed in outcomes after appendicitis,” according to the authors.
“It may be hospitals that are more used to serving racial-ethnic minority patients are better at diagnosing them, because they’re more culturally informed and have a better understanding of these patients,” Dr. Stey said in a news release about their findings.
Great masquerader
Diagnosing appendicitis can be challenging, Dr. Carter said. The early signs can be subtle, and the condition is sometimes called the great masquerader. It is not uncommon for patients to be diagnosed with gastroenteritis or pain associated with their menstrual period, for example, and sent home.
Scoring systems based on patients’ symptoms and liberal use of imaging have improved detection of appendicitis, but “no physician or health care system is perfect in the diagnosis,” he said.
The increased odds of delayed diagnosis for Black patients remained when the researchers focused on healthier patients who had fewer comorbidities, and it also held when they considered patients with private insurance in high-income areas, Dr. Carter noted.
“Once again, with this study we see the association of structural and systematic racism with access to health care, especially for Black patients, in emergency departments and hospitals,” he wrote. “We must redouble our efforts to become anti-racist in ourselves, our institutions, and our profession.”
‘Our health care system itself’
Elizabeth Garner, MD, MPH, a pharmaceutical executive who was not involved in the study, commented on Twitter that the study points to an underlying issue that has existed in medicine “for quite some time.”
“Minority populations are not taken as seriously as their white counterparts,” she wrote. “This needs to change.”
Measures of hospital quality need to be tied to health equity, according to Mofya Diallo, MD, MPH, of the department of anesthesiology at the Children’s Hospital Los Angeles and the University of Southern California, Los Angeles.
“Top hospitals should take pride in outcomes that do not vary based on race, income or literacy,” she tweeted in response to the study.
To better understand possible reasons for delayed diagnosis, future researchers could assess whether patients who are Black are less likely to receive a surgical consultation, imaging studies, or lab work, Dr. Carter told this news organization. He pointed to a recent analysis of patients insured by Medicare that found that Black patients were less likely than White patients to receive a surgical consultation after they were admitted with colorectal, general abdominal, hepatopancreatobiliary, intestinal obstruction, or upper gastrointestinal diagnoses.
While social determinants of health, such as income, education, housing, early childhood development, employment, and social inclusion, may account for a substantial portion of health outcomes, “Our health care system itself can be viewed as another social determinant of health,” Dr. Carter wrote. “Insurance coverage, health care professional availability, health care professional linguistic and cultural competency, and quality of care all have an effect on health outcomes.”

Key factors predict gallbladder cancer on routine cholecystectomy
The study covered in this summary was published on researchsquare.com as a preprint and has not yet been peer reviewed.
Key takeaway
Why this matters
- More than 60% of gallbladder cancers are diagnosed incidentally following cholecystectomy for benign reasons.
- Identifying predictors allows surgeons to send high-risk individuals for oncologic evaluation beforehand and to prepare for intraoperative frozen pathology and more appropriate surgery, including extended cholecystectomy and lymph node dissection.
Study design
- The investigators analyzed 403,443 cholecystectomies in the American College of Surgeons’ NSQIP database from 2007 to 2017.
- They used multivariable logistic regression to identify risk factors for gallbladder cancers.
- Patients undergoing cholecystectomy for suspected or confirmed gallbladder cancer were excluded.
Key results
- The incidence of gallbladder cancer was 0.11% (441 of 403,443 patients).
- Preoperative factors significantly associated with gallbladder cancer included age older than 60 years (odds ratio [OR], 6.51), female sex (OR, 1.75), weight loss (OR, 2.58), and elevated alkaline phosphatase level (OR, 1.67).
- Starting with or converting to an open approach – both potential indicators of more complex disease – were associated with seven times’ higher odds of gallbladder cancer (OR, 7.33; P < .001), as were longer operative times (127 minutes vs. 70.7 minutes; P < .001).
Limitations
- There is a risk of selection bias regarding which patients were included in the database.
- Presenting symptoms, preoperative imaging findings, and pathologic staging were not available.
- The database did not record the reasons for choosing open surgery rather than laparoscopic surgery or for converting to an open approach.
Disclosures
- There was no funding for the work, and the investigators did not disclose any relevant financial relationships.

The study covered in this summary was published on researchsquare.com as a preprint and has not yet been peer reviewed.
Key takeaway
Why this matters
- More than 60% of gallbladder cancers are diagnosed incidentally following cholecystectomy for benign reasons.
- Identifying predictors allows surgeons to send high-risk individuals for oncologic evaluation beforehand and to prepare for intraoperative frozen pathology and more appropriate surgery, including extended cholecystectomy and lymph node dissection.
Study design
- The investigators analyzed 403,443 cholecystectomies in the American College of Surgeons’ NSQIP database from 2007 to 2017.
- They used multivariable logistic regression to identify risk factors for gallbladder cancers.
- Patients undergoing cholecystectomy for suspected or confirmed gallbladder cancer were excluded.
Key results
- The incidence of gallbladder cancer was 0.11% (441 of 403,443 patients).
- Preoperative factors significantly associated with gallbladder cancer included age older than 60 years (odds ratio [OR], 6.51), female sex (OR, 1.75), weight loss (OR, 2.58), and elevated alkaline phosphatase level (OR, 1.67).
- Starting with or converting to an open approach – both potential indicators of more complex disease – were associated with seven times’ higher odds of gallbladder cancer (OR, 7.33; P < .001), as were longer operative times (127 minutes vs. 70.7 minutes; P < .001).
Limitations
- There is a risk of selection bias regarding which patients were included in the database.
- Presenting symptoms, preoperative imaging findings, and pathologic staging were not available.
- The database did not record the reasons for choosing open surgery rather than laparoscopic surgery or for converting to an open approach.
Disclosures
- There was no funding for the work, and the investigators did not disclose any relevant financial relationships.

A patient named ‘Settle’ decides to sue instead
On Nov. 1, 2020, Dallas Settle went to Plateau Medical Center, Oak Hill, W.Va., complaining of pain that was later described in court documents as being “in his right mid-abdomen migrating to his right lower abdomen.” Following a CT scan, Mr. Settle was diagnosed with diverticulitis resulting in pneumoperitoneum, which is the presence of air or other gas in the abdominal cavity. The patient, it was decided, required surgery to correct the problem, but Plateau Medical Center didn’t have the staff to perform the procedure.
Mr. Settle was then transferred to another West Virginia hospital, Charleston Area Medical Center (CAMC). Here, he was evaluated by doctors in the facility’s General Division, who initiated treatment with IV fluids and opiate analgesics. He was then placed under the care of a trauma surgeon, who initially decided to treat the patient nonoperatively. If that approach failed, the surgeon believed, Mr. Settle would probably require a laparotomy, bowel resection, and ostomy.
Another surgical team performed an exploratory laparotomy the following day. The team determined that Mr. Settle was suffering from a ruptured appendicitis and allegedly performed an appendectomy. But Mr. Settle’s condition continued to deteriorate the following day.
Another CT scan followed. It revealed various problems – multiple fluid collections, an ileus, distended loops of the patient’s small bowel, a left renal cyst, subcentimeter mesenteric, and retroperitoneal adenopathy. Additional CT scans conducted 4 days later indicated other problems, including fluid collections in the patient’s right- and left-lower quadrants.
Over the next few days, doctors performed further exploratory laparotomies. Finally, on Nov. 22, Mr. Settle was transferred out of the intensive care unit in preparation for his discharge the following day.
His pain continued to worsen, however, and he was readmitted to CAMC a day later. At this point, an examination revealed that his surgical incisions had become infected.
Worse news was on the horizon. On Nov. 28, the trauma surgeon who had first agreed to treat Mr. Settle informed him that, despite claims to the contrary, his appendix hadn’t been removed.
Eventually, Mr. Settle was referred to the Cleveland Clinic, where at press time he was still being treated.
Mr. Settle has hired the firm Calwell Luce diTrapano to sue CAMC, accusing it of medical malpractice, medical negligence, and other lapses in the standard of care. In his complaint, he accused the hospital and its staff of breaching their duty of care “by negligently and improperly treating him” and by failing “to exercise the degree of care, skill, and learning required and expected of reasonable health care providers.”
His suit seeks not only compensatory damages and other relief but also punitive damages.

‘Game changer’: Thyroid cancer recurrence no higher with lobectomy
Patients with intermediate-risk papillary thyroid cancer and lymph node metastasis show no significant increase in tumor recurrence when undergoing lobectomy compared with a total thyroidectomy, new research shows.
“Results of this cohort study suggest that patients with ipsilateral clinical lateral neck metastasis (cN1b) papillary thyroid cancer who underwent lobectomy exhibited recurrence-free survival rates similar to those who underwent total thyroidectomy after controlling for major prognostic factors,” the authors conclude in the study published online in JAMA Surgery.
“These findings suggest that cN1b alone should not be an absolute indication for total thyroidectomy,” they note.
The study, involving the largest cohort to date to compare patients with intermediate-risk papillary thyroid cancer treated with lobectomy versus total thyroidectomy, “challenged the current guidelines and pushed the boundary of limited surgical treatment even further,” say Michelle B. Mulder, MD, and Quan-Yang Duh, MD, of the department of surgery, University of California, San Francisco, in an accompanying editorial.
“It can be a game changer if confirmed by future prospective and multicenter studies,” they add.
Guidelines still recommend total thyroidectomy with subsequent RAI
While lower-intensity treatment options, with a lower risk of complications, have gained favor in the treatment of low-risk papillary thyroid cancer, guidelines still recommend the consideration of total thyroidectomy and subsequent radioactive iodine ablation (RAI) for intermediate-risk cancers because of the higher chance of recurrence, particularly among those with clinically positive nodes.
However, data on the superiority of a total thyroidectomy, with or without RAI, versus lobectomy is inconsistent, prompting first author Siyuan Xu, MD, of the department of head and neck surgical oncology, National Cancer Center, Beijing, and colleagues to compare the risk of recurrence with the two approaches.
For the study, patients with intermediate-risk papillary thyroid cancer treated at the Chinese Academy of Medical Sciences Cancer Hospital in Beijing between January 2000 and December 2017, who had a lobectomy or total thyroidectomy, were paired 1:1 in a propensity score matching analysis.
Other than treatment type, the 265 pairs of patients were matched based on all other potential prognostic factors, including age, sex, primary tumor size, minor extrathyroidal extension, multifocality, number of lymph node metastases, and lymph node ratio.
Participants were a mean age of 37 years and 66% were female.
With a median follow-up of 60 months in the lobectomy group and 58 months in the total thyroidectomy group, structural recurrences occurred in 7.9% (21) and 6.4% (17) of patients, respectively, which was not significantly different.
The primary endpoint, 5-year rate of recurrence-free survival, was also not significantly different between the lobectomy (92.3%) and total thyroidectomy groups (93.7%) (adjusted hazard ratio, 1.10; P = .77).
In a further stratified analysis of patients treated with total thyroidectomy along with RAI (n = 75), the lack of a significant difference in recurrence-free survival versus lobectomy remained (aHR, 0.59; P = .46).
The results were similar in unadjusted as well as adjusted analyses, and a power analysis indicated that the study had a 90% power to detect a more than 4.9% difference in recurrence-free survival.
“Given the lower complication rate of lobectomy, a maximal 4.9% recurrence-free survival difference is acceptable, which enhances the reliability of the study results,” the authors say.
They conclude that “our findings call into question whether cN1b alone [ipsilateral clinical lateral neck metastasis papillary thyroid cancer] should be an absolute determinant for deciding the optimal extent of thyroid surgery for papillary thyroid cancer.”
With total thyroidectomy, RAI can be given
An important argument in favor of total thyroidectomy is that with the complete resection of thyroid tissue, RAI ablation can then be used for postoperative detection of residual or metastatic disease, as well as for treatment, the authors note.
Indeed, a study using the Surveillance, Epidemiology, and End Results (SEER) database showed RAI ablation is associated with a 29% reduction in the risk of death in patients with intermediate-risk papillary thyroid cancer, with a hazard risk of 0.71.
However, conflicting data from Memorial Sloan-Kettering Cancer Center, New York, suggests no significant benefit with total thyroidectomy and RAI ablation.
The current study’s analysis of patients treated with RAI, though limited in size, supports the latter study’s findings, the authors note.
“When we performed further stratified analyses in patients treated with total thyroidectomy plus RAI ablation and their counterparts, no significant difference was found, which conformed with [the] result from the whole cohort.”
“Certainly, the stratified comparison did not have enough power to examine the effect of RAI ablation on tumor recurrence subject to the limitation of sample size and case selection [and] further study is needed on this topic,” they write.
Some limitations warrant cautious interpretation
In their editorial, Dr. Mulder and Dr. Duh note that while some previous studies have shown similar outcomes relating to tumor size, thyroid hormone suppression therapy, and multifocality, “few have addressed lateral neck involvement.”
They suggest cautious interpretation, however, due to limitations, acknowledged by the authors, including the single-center nature of the study.
“Appropriate propensity matching may mitigate selection bias but cannot eliminate it entirely and their findings may not be replicated in other institutions by other surgeons,” they note.
Other limitations include that changes in clinical practice and patient selection were likely over the course of the study because of significant changes in American Thyroid Association (ATA) guidelines between 2009 and 2017, and characteristics including molecular genetic testing, which could have influenced final results, were not taken into consideration.
Furthermore, for patients with intermediate-risk cancer, modifications in postoperative follow-up are necessary following lobectomy versus total thyroidectomy; “the role of radioiodine is limited and the levels of thyroglobulin more complicated to interpret,” they note.
The study and editorial authors had no disclosures to report.

Surgical site dressing turns blue when it needs changing
Surgical site infections are one of the top causes of postoperative morbidity and death worldwide, but there is little agreement and much debate over the most effective wound dressing to improve outcomes and reduce the health care burden.
Recent clinical trials have indicated that transparent, semiocclusive films have advantages over gauze held by adhesive tape.
But current transparent film bandages may become dislodged during activities such as showering, say authors of a pilot study published in the Journal of Wound Care. Patients may not realize the bandage has been disrupted, which can lead to infection.
.
“Clinicians, patients, and caregivers are alerted to the loss of dressing integrity and can replace the dressing when any portion of the perimeter changes to a blue [color],” the authors explain. “In addition, the dressing turns blue when the central pad is saturated with fluid, allowing the patient or provider to change the dressing.”
DSD is indicated for wounds that have low levels of exudate.
Two transparent film dressings compared
Researchers recruited 20 patients from the general population in Pittsburgh, for a small pilot study to test DSD against a comparator film dressing (3M Tegaderm + Pad). The volunteers received “a small stipend,” according to the paper.
A 1.5-centimeter incision was made in both forearms of each volunteer. The forearms were randomized regarding which got which bandage. Both bandages have been cleared by the U.S. Food and Drug Administration as nonsignificant-risk devices.
Volunteers were instructed to wear the dressing and continue their typical activities of daily living.
The average age of the volunteers was 52 years (range, 20-80 years). Among the 20 volunteers, 11 reported no comorbidities, and 45% reported at least one comorbidity.
Most of the volunteers favored DSD over the comparator in a postoperative survey – 75% to 25%, according to the report.
The wear time between the two transparent dressings across all subjects was 1.4 days. There was no difference in wear time, logged by the volunteers, between the two groups.
There were no infectious complications, the paper states.
The maker, DrySee (Houston), which holds three patents on the product, supported the research with an unrestricted grant.
DrySee CEO Brad Greer told this news organization, “With DrySee, you know when to change your dressing. All other dressings look the same wet, saturated, or dry.”
He said the study confirms what they have seen in practice, adding that the product is unique.
“No one else in the world has this technology,” Mr. Greer said.
Surgeons want to see more data
Heather Evans, MD, a general surgeon with the Medical University of South Carolina, MUSC Health, Charleston, who was not involved with the study, praised the color-indicator design and said she liked the bandage’s narrow indication for low-exudate wounds.
She said in an interview, “It’s a lot to put on a layperson to suddenly know how to take care of wounds when you leave the hospital.”
Giving them the confidence that their wound is safe if the blue doesn’t appear “is a really cool concept,” she said.
She said that, although the volunteers included some elderly people and people with conditions such as diabetes that could affect wound healing, the bandage needs to be tested with a bigger trial to see if it is effective outside controlled conditions.
She also said that some occlusive dressings will be more durable and stay on days longer than DSD or the comparator, which may affect the choice for some.
“The average length of dressing time in this study was less than 2 days,” she pointed out.
Jim Rickert, MD, an orthopedic surgeon with Indiana University Health Bedford, who was not involved with the study, agreed that any surgical or wound dressing, including transparent films, can become dislodged, and said, “This type of product has promise but this is a small pilot study. I would want to see results from a trial of actual surgical patients to see if this type of dressing did indeed decrease post-op infections compared to standard dressing materials.”
Not all are convinced either that there is a need to be filled or that DSD will be the right solution.
Therese Duane, MD, a general surgeon with Texas Health Harris Methodist Fort Worth, who was not part of the study, said in an interview that she “has no issues with the current products.”
She added that more information is needed before considering DSD a better solution, including animal studies and use “on very sick patients.”
“Twenty volunteers with cuts on their arm is barely a start for comparison,” she said.
The authors, led by Kristy Breisinger, a research analyst with the SerenaGroup Research Foundation in Cambridge, Mass., acknowledged the limitations, including the small sample size and that the trial was conducted at only one institution. Additionally, the analysis is based on descriptive statistics.
They write that the trial design was chosen “to simulate a real-world setting that is not always achievable in animal studies.”
The research was sponsored by an unrestricted grant from the maker of DSD, DrySee Inc., in Houston.
Mr. Greer is DrySee’s CEO. The authors and Dr. Duane, Dr. Rickert, and Dr. Evans declared no relevant financial relationships.

“Clinicians, patients, and caregivers are alerted to the loss of dressing integrity and can replace the dressing when any portion of the perimeter changes to a blue [color],” the authors explain. “In addition, the dressing turns blue when the central pad is saturated with fluid, allowing the patient or provider to change the dressing.”
DSD is indicated for wounds that have low levels of exudate.
Two transparent film dressings compared
Researchers recruited 20 patients from the general population in Pittsburgh, for a small pilot study to test DSD against a comparator film dressing (3M Tegaderm + Pad). The volunteers received “a small stipend,” according to the paper.
A 1.5-centimeter incision was made in both forearms of each volunteer. The forearms were randomized regarding which got which bandage. Both bandages have been cleared by the U.S. Food and Drug Administration as nonsignificant-risk devices.
Volunteers were instructed to wear the dressing and continue their typical activities of daily living.
The average age of the volunteers was 52 years (range, 20-80 years). Among the 20 volunteers, 11 reported no comorbidities, and 45% reported at least one comorbidity.
Most of the volunteers favored DSD over the comparator in a postoperative survey – 75% to 25%, according to the report.
The wear time between the two transparent dressings across all subjects was 1.4 days. There was no difference in wear time, logged by the volunteers, between the two groups.
There were no infectious complications, the paper states.
The maker, DrySee (Houston), which holds three patents on the product, supported the research with an unrestricted grant.
DrySee CEO Brad Greer told this news organization, “With DrySee, you know when to change your dressing. All other dressings look the same wet, saturated, or dry.”
He said the study confirms what they have seen in practice, adding that the product is unique.
“No one else in the world has this technology,” Mr. Greer said.
Surgeons want to see more data
Heather Evans, MD, a general surgeon with the Medical University of South Carolina, MUSC Health, Charleston, who was not involved with the study, praised the color-indicator design and said she liked the bandage’s narrow indication for low-exudate wounds.
She said in an interview, “It’s a lot to put on a layperson to suddenly know how to take care of wounds when you leave the hospital.”
Giving them the confidence that their wound is safe if the blue doesn’t appear “is a really cool concept,” she said.
She said that, although the volunteers included some elderly people and people with conditions such as diabetes that could affect wound healing, the bandage needs to be tested with a bigger trial to see if it is effective outside controlled conditions.
She also said that some occlusive dressings will be more durable and stay on days longer than DSD or the comparator, which may affect the choice for some.
“The average length of dressing time in this study was less than 2 days,” she pointed out.
Jim Rickert, MD, an orthopedic surgeon with Indiana University Health Bedford, who was not involved with the study, agreed that any surgical or wound dressing, including transparent films, can become dislodged, and said, “This type of product has promise but this is a small pilot study. I would want to see results from a trial of actual surgical patients to see if this type of dressing did indeed decrease post-op infections compared to standard dressing materials.”
Not all are convinced either that there is a need to be filled or that DSD will be the right solution.
Therese Duane, MD, a general surgeon with Texas Health Harris Methodist Fort Worth, who was not part of the study, said in an interview that she “has no issues with the current products.”
She added that more information is needed before considering DSD a better solution, including animal studies and use “on very sick patients.”
“Twenty volunteers with cuts on their arm is barely a start for comparison,” she said.
The authors, led by Kristy Breisinger, a research analyst with the SerenaGroup Research Foundation in Cambridge, Mass., acknowledged the limitations, including the small sample size and that the trial was conducted at only one institution. Additionally, the analysis is based on descriptive statistics.
They write that the trial design was chosen “to simulate a real-world setting that is not always achievable in animal studies.”
The research was sponsored by an unrestricted grant from the maker of DSD, DrySee Inc., in Houston.
Mr. Greer is DrySee’s CEO. The authors and Dr. Duane, Dr. Rickert, and Dr. Evans declared no relevant financial relationships.

Surgical site infections are one of the top causes of postoperative morbidity and death worldwide, but there is little agreement and much debate over the most effective wound dressing to improve outcomes and reduce the health care burden.
Recent clinical trials have indicated that transparent, semiocclusive films have advantages over gauze held by adhesive tape.
But current transparent film bandages may become dislodged during activities such as showering, say authors of a pilot study published in the Journal of Wound Care. Patients may not realize the bandage has been disrupted, which can lead to infection.

Real-world evidence seen for metal stents in biliary strictures
A real-world analysis in the United Kingdom found that a fully covered metal stent is safe and effective at controlling anastomotic strictures (AS) following liver transplants.
Biliary AS occurs in an estimated 5%-32% of patients following a liver transplant. Generally, these have been managed by insertion of side-by-side plastic stents to remodel the stricture, but this often required multiple procedures to resolve the problem. More recently, transpapillary fully covered self-expanding metallic stents (FCSEMSs) have been introduced and they appear to perform equivalently to their plastic counterparts while requiring fewer procedures.
The new study “is yet another large experience demonstrating that use of fully covered metal stents for treating anastomotic biliary strictures is highly effective and also cost-effective because you really decrease the number of ERCPs [endoscopic retrograde cholangiopancreatographies] that are required to treat an anastomotic stricture,” said Vladimir Kushnir, MD, who was asked to comment on the study, which was published in Therapeutic Advances in Gastroenterology.
The researchers analyzed retrospective data from 162 consecutive patients who underwent ERCP with intraductal self-expanding metal stent (IDSEMS) insertion at nine tertiary centers. The procedures employed the Kaffes (Taewoong Niti-S) biliary covered stent, which is not available in the United States. Unlike conventional FCSEMSs, the device does not have to traverse the papilla. It is also shorter and includes an antimigration waist and removal wires that may reduce the risk of silent migration. Small case series suggested efficacy in the treatment of post–liver transplant AS.
There were 176 episodes of stent insertion among the 162 included patients; 62% of patients were male, and the median age at transplant was 54 years. Etiologies included hepatocellular carcinoma (22%), alcohol-related liver disease (18%), and nonalcoholic fatty liver disease (12%). The median time to development of a stricture was 24.9 weeks. Among all patients, 35% had previously received stents; 75% of those were plastic stents.
Overall, 10% of patients experienced stricture recurrence at a median interval of 19 weeks following stent removal. Median stent emplacement was 15 weeks, and 81% of patients had a resolution of their strictures.
Dr. Kushnir, from Washington University in St. Louis, highlighted the differences between the stent used in the study and those currently available in the United States. “This type of stent is a self-expanding metal stent that’s covered, but what’s different about it is that it’s designed to go completely within the bile duct, whereas a traditional fully covered metal stent traverses the major duodenal papilla.”
Despite those differences, he believes that the study can inform current practice in the United States. “In situations where you’re faced with a question of whether or not you leave multiple plastic stents in, or you put a full metal stent in that’s going to be fully within the bile duct, I think this data does provide some reassurance. If you’re using one of the traditional stents that we have in the United States and putting it fully within the bile duct, you do need to be prepared to have a little bit of a harder time removing the stent when the time comes for the removal procedure, which could require cholangioscopy. But this does provide some evidence to back up the practice of using fully covered metal stents fully within the bile duct to remediate anastomotic strictures that may be just a little too high up to treat traditionally with a stent that remains transpapillary,” said Dr. Kushnir.
The study also suggests an avenue for further research. “What’s also interesting about this study is that they only left the stents in for 3 months. In most clinical trials, where we’ve used fully covered metal stents for treating anastomotic biliary strictures, you leave the stent in from anywhere from 6 to 12 months. So with only 3 months dwell time they were able to get pretty impressive results, at least in the short term, in a retrospective study, so it does raise the question of should we be evaluating shorter dwell times for stents in treating anastomotic strictures when we’re using a fully covered metal stent that’s a larger diameter?” said Dr. Kushnir.
The authors noted some limitations, such as the retrospective design, small sample size, and lack of control group. They also noted that the multicenter design may have introduced heterogeneity in patient management and follow-up.
“In conclusion, IDSEMS appear to be safe and highly efficacious in the management of [post–liver transplant] AS,” concluded the authors. “Long-term outcomes appear good with low rates of AS recurrence.”
The authors declare no conflicts of interest. Dr. Kushnir is a consultant for ConMed and Boston Scientific.

New ESC guidelines for cutting CV risk in noncardiac surgery
The European Society of Cardiology guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery have seen extensive revision since the 2014 version.
They still have the same aim – to prevent surgery-related bleeding complications, perioperative myocardial infarction/injury (PMI), stent thrombosis, acute heart failure, arrhythmias, pulmonary embolism, ischemic stroke, and cardiovascular (CV) death.
Cochairpersons Sigrun Halvorsen, MD, PhD, and Julinda Mehilli, MD, presented highlights from the guidelines at the annual congress of the European Society of Cardiology and the document was simultaneously published online in the European Heart Journal.
The document classifies noncardiac surgery into three levels of 30-day risk of CV death, MI, or stroke. Low (< 1%) risk includes eye or thyroid surgery; intermediate (1%-5%) risk includes knee or hip replacement or renal transplant; and high (> 5%) risk includes aortic aneurysm, lung transplant, or pancreatic or bladder cancer surgery (see more examples below).
It classifies patients as low risk if they are younger than 65 without CV disease or CV risk factors (smoking, hypertension, diabetes, dyslipidemia, family history); intermediate risk if they are 65 or older or have CV risk factors; and high risk if they have CVD.
In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:
First, recommendations for preoperative ECG and biomarkers are more specific, he noted.
The guidelines advise that before intermediate- or high-risk noncardiac surgery, in patients who have known CVD, CV risk factors (including age 65 or older), or symptoms suggestive of CVD:
- It is recommended to obtain a preoperative 12-lead ECG (class I).
- It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
- It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).
However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).
Troponins have a stronger class I recommendation, compared with the IIA recommendation for BNP, because they are useful for preoperative risk stratification and for diagnosis of PMI, Dr. Halvorsen explained. “Patients receive painkillers after surgery and may have no pain,” she noted, but they may have PMI, which has a bad prognosis.
Second, the guidelines recommend that “all patients should stop smoking 4 weeks before noncardiac surgery [class I],” she noted. Clinicians should also “measure hemoglobin, and if the patient is anemic, treat the anemia.”
Third, the sections on antithrombotic treatment have been significantly revised. “Bridging – stopping an oral antithrombotic drug and switching to a subcutaneous or IV drug – has been common,” Dr. Halvorsen said, “but recently we have new evidence that in most cases that increases the risk of bleeding.”
“We are [now] much more restrictive with respect to bridging” with unfractionated heparin or low-molecular-weight heparin, she said. “We recommend against bridging in patients with low to moderate thrombotic risk,” and bridging should only be considered in patients with mechanical prosthetic heart valves or with very high thrombotic risk.
More preoperative recommendations
In the guideline overview session at the congress, Dr. Halverson highlighted some of the new recommendations for preoperative risk assessment.
If time allows, it is recommended to optimize guideline-recommended treatment of CVD and control of CV risk factors including blood pressure, dyslipidemia, and diabetes, before noncardiac surgery (class I).
Patients commonly have “murmurs, chest pain, dyspnea, and edema that may suggest severe CVD, but may also be caused by noncardiac disease,” she noted. The guidelines state that “for patients with a newly detected murmur and symptoms or signs of CVD, transthoracic echocardiography is recommended before noncardiac surgery (class I).
“Many studies have been performed to try to find out if initiation of specific drugs before surgery could reduce the risk of complications,” Dr. Halvorsen noted. However, few have shown any benefit and “the question of presurgery initiation of beta-blockers has been greatly debated,” she said. “We have again reviewed the literature and concluded ‘Routine initiation of beta-blockers perioperatively is not recommended (class IIIA).’ “
“We adhere to the guidelines on acute and chronic coronary syndrome recommending 6-12 months of dual antiplatelet treatment as a standard before elective surgery,” she said. “However, in case of time-sensitive surgery, the duration of that treatment can be shortened down to a minimum of 1 month after elective PCI and a minimum of 3 months after PCI and ACS.”
Patients with specific types of CVD
Dr. Mehilli, a professor at Landshut-Achdorf (Germany) Hospital, highlighted some new guideline recommendations for patients who have specific types of cardiovascular disease.
Coronary artery disease (CAD). “For chronic coronary syndrome, a cardiac workup is recommended only for patients undergoing intermediate risk or high-risk noncardiac surgery.”
“Stress imaging should be considered before any high risk, noncardiac surgery in asymptomatic patients with poor functional capacity and prior PCI or coronary artery bypass graft (new recommendation, class IIa).”
Mitral valve regurgitation. For patients undergoing scheduled noncardiac surgery, who remain symptomatic despite guideline-directed medical treatment for mitral valve regurgitation (including resynchronization and myocardial revascularization), consider a valve intervention – either transcatheter or surgical – before noncardiac surgery in eligible patients with acceptable procedural risk (new recommendation).
Cardiac implantable electronic devices (CIED). For high-risk patients with CIEDs undergoing noncardiac surgery with high probability of electromagnetic interference, a CIED checkup and necessary reprogramming immediately before the procedure should be considered (new recommendation).
Arrhythmias. “I want only to stress,” Dr. Mehilli said, “in patients with atrial fibrillation with acute or worsening hemodynamic instability undergoing noncardiac surgery, an emergency electrical cardioversion is recommended (class I).”
Peripheral artery disease (PAD) and abdominal aortic aneurysm. For these patients “we do not recommend a routine referral for a cardiac workup. But we recommend it for patients with poor functional capacity or with significant risk factors or symptoms (new recommendations).”
Chronic arterial hypertension. “We have modified the recommendation, recommending avoidance of large perioperative fluctuations in blood pressure, and we do not recommend deferring noncardiac surgery in patients with stage 1 or 2 hypertension,” she said.
Postoperative cardiovascular complications
The most frequent postoperative cardiovascular complication is PMI, Dr. Mehilli noted.
“In the BASEL-PMI registry, the incidence of this complication around intermediate or high-risk noncardiac surgery was up to 15% among patients older than 65 years or with a history of CAD or PAD, which makes this kind of complication really important to prevent, to assess, and to know how to treat.”
“It is recommended to have a high awareness for perioperative cardiovascular complications, combined with surveillance for PMI in patients undergoing intermediate- or high-risk noncardiac surgery” based on serial measurements of high-sensitivity cardiac troponin.
The guidelines define PMI as “an increase in the delta of high-sensitivity troponin more than the upper level of normal,” Dr. Mehilli said. “It’s different from the one used in a rule-in algorithm for non-STEMI acute coronary syndrome.”
Postoperative atrial fibrillation (AFib) is observed in 2%-30% of noncardiac surgery patients in different registries, particularly in patients undergoing intermediate or high-risk noncardiac surgery, she noted.
“We propose an algorithm on how to prevent and treat this complication. I want to highlight that in patients with hemodynamic unstable postoperative AF[ib], an emergency cardioversion is indicated. For the others, a rate control with the target heart rate of less than 110 beats per minute is indicated.”
In patients with postoperative AFib, long-term oral anticoagulation therapy should be considered in all patients at risk for stroke, considering the anticipated net clinical benefit of oral anticoagulation therapy as well as informed patient preference (new recommendations).
Routine use of beta-blockers to prevent postoperative AFib in patients undergoing noncardiac surgery is not recommended.
The document also covers the management of patients with kidney disease, diabetes, cancer, obesity, and COVID-19. In general, elective noncardiac surgery should be postponed after a patient has COVID-19, until he or she recovers completely, and coexisting conditions are optimized.
The guidelines are available from the ESC website in several formats: pocket guidelines, pocket guidelines smartphone app, guidelines slide set, essential messages, and the European Heart Journal article.
Noncardiac surgery risk categories
The guideline includes a table that classifies noncardiac surgeries into three groups, based on the associated 30-day risk of death, MI, or stroke:
- Low (< 1%): breast, dental, eye, thyroid, and minor gynecologic, orthopedic, and urologic surgery.
- Intermediate (1%-5%): carotid surgery, endovascular aortic aneurysm repair, gallbladder surgery, head or neck surgery, hernia repair, peripheral arterial angioplasty, renal transplant, major gynecologic, orthopedic, or neurologic (hip or spine) surgery, or urologic surgery
- High (> 5%): aortic and major vascular surgery (including aortic aneurysm), bladder removal (usually as a result of cancer), limb amputation, lung or liver transplant, pancreatic surgery, or perforated bowel repair.
The guidelines were endorsed by the European Society of Anaesthesiology and Intensive Care. The guideline authors reported numerous disclosures.

- It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
- It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).
However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).
Troponins have a stronger class I recommendation, compared with the IIA recommendation for BNP, because they are useful for preoperative risk stratification and for diagnosis of PMI, Dr. Halvorsen explained. “Patients receive painkillers after surgery and may have no pain,” she noted, but they may have PMI, which has a bad prognosis.
Second, the guidelines recommend that “all patients should stop smoking 4 weeks before noncardiac surgery [class I],” she noted. Clinicians should also “measure hemoglobin, and if the patient is anemic, treat the anemia.”
Third, the sections on antithrombotic treatment have been significantly revised. “Bridging – stopping an oral antithrombotic drug and switching to a subcutaneous or IV drug – has been common,” Dr. Halvorsen said, “but recently we have new evidence that in most cases that increases the risk of bleeding.”
“We are [now] much more restrictive with respect to bridging” with unfractionated heparin or low-molecular-weight heparin, she said. “We recommend against bridging in patients with low to moderate thrombotic risk,” and bridging should only be considered in patients with mechanical prosthetic heart valves or with very high thrombotic risk.
More preoperative recommendations
In the guideline overview session at the congress, Dr. Halverson highlighted some of the new recommendations for preoperative risk assessment.
If time allows, it is recommended to optimize guideline-recommended treatment of CVD and control of CV risk factors including blood pressure, dyslipidemia, and diabetes, before noncardiac surgery (class I).
Patients commonly have “murmurs, chest pain, dyspnea, and edema that may suggest severe CVD, but may also be caused by noncardiac disease,” she noted. The guidelines state that “for patients with a newly detected murmur and symptoms or signs of CVD, transthoracic echocardiography is recommended before noncardiac surgery (class I).
“Many studies have been performed to try to find out if initiation of specific drugs before surgery could reduce the risk of complications,” Dr. Halvorsen noted. However, few have shown any benefit and “the question of presurgery initiation of beta-blockers has been greatly debated,” she said. “We have again reviewed the literature and concluded ‘Routine initiation of beta-blockers perioperatively is not recommended (class IIIA).’ “
“We adhere to the guidelines on acute and chronic coronary syndrome recommending 6-12 months of dual antiplatelet treatment as a standard before elective surgery,” she said. “However, in case of time-sensitive surgery, the duration of that treatment can be shortened down to a minimum of 1 month after elective PCI and a minimum of 3 months after PCI and ACS.”
Patients with specific types of CVD
Dr. Mehilli, a professor at Landshut-Achdorf (Germany) Hospital, highlighted some new guideline recommendations for patients who have specific types of cardiovascular disease.
Coronary artery disease (CAD). “For chronic coronary syndrome, a cardiac workup is recommended only for patients undergoing intermediate risk or high-risk noncardiac surgery.”
“Stress imaging should be considered before any high risk, noncardiac surgery in asymptomatic patients with poor functional capacity and prior PCI or coronary artery bypass graft (new recommendation, class IIa).”
Mitral valve regurgitation. For patients undergoing scheduled noncardiac surgery, who remain symptomatic despite guideline-directed medical treatment for mitral valve regurgitation (including resynchronization and myocardial revascularization), consider a valve intervention – either transcatheter or surgical – before noncardiac surgery in eligible patients with acceptable procedural risk (new recommendation).
Cardiac implantable electronic devices (CIED). For high-risk patients with CIEDs undergoing noncardiac surgery with high probability of electromagnetic interference, a CIED checkup and necessary reprogramming immediately before the procedure should be considered (new recommendation).
Arrhythmias. “I want only to stress,” Dr. Mehilli said, “in patients with atrial fibrillation with acute or worsening hemodynamic instability undergoing noncardiac surgery, an emergency electrical cardioversion is recommended (class I).”
Peripheral artery disease (PAD) and abdominal aortic aneurysm. For these patients “we do not recommend a routine referral for a cardiac workup. But we recommend it for patients with poor functional capacity or with significant risk factors or symptoms (new recommendations).”
Chronic arterial hypertension. “We have modified the recommendation, recommending avoidance of large perioperative fluctuations in blood pressure, and we do not recommend deferring noncardiac surgery in patients with stage 1 or 2 hypertension,” she said.
Postoperative cardiovascular complications
The most frequent postoperative cardiovascular complication is PMI, Dr. Mehilli noted.
“In the BASEL-PMI registry, the incidence of this complication around intermediate or high-risk noncardiac surgery was up to 15% among patients older than 65 years or with a history of CAD or PAD, which makes this kind of complication really important to prevent, to assess, and to know how to treat.”
“It is recommended to have a high awareness for perioperative cardiovascular complications, combined with surveillance for PMI in patients undergoing intermediate- or high-risk noncardiac surgery” based on serial measurements of high-sensitivity cardiac troponin.
The guidelines define PMI as “an increase in the delta of high-sensitivity troponin more than the upper level of normal,” Dr. Mehilli said. “It’s different from the one used in a rule-in algorithm for non-STEMI acute coronary syndrome.”
Postoperative atrial fibrillation (AFib) is observed in 2%-30% of noncardiac surgery patients in different registries, particularly in patients undergoing intermediate or high-risk noncardiac surgery, she noted.
“We propose an algorithm on how to prevent and treat this complication. I want to highlight that in patients with hemodynamic unstable postoperative AF[ib], an emergency cardioversion is indicated. For the others, a rate control with the target heart rate of less than 110 beats per minute is indicated.”
In patients with postoperative AFib, long-term oral anticoagulation therapy should be considered in all patients at risk for stroke, considering the anticipated net clinical benefit of oral anticoagulation therapy as well as informed patient preference (new recommendations).
Routine use of beta-blockers to prevent postoperative AFib in patients undergoing noncardiac surgery is not recommended.
The document also covers the management of patients with kidney disease, diabetes, cancer, obesity, and COVID-19. In general, elective noncardiac surgery should be postponed after a patient has COVID-19, until he or she recovers completely, and coexisting conditions are optimized.
The guidelines are available from the ESC website in several formats: pocket guidelines, pocket guidelines smartphone app, guidelines slide set, essential messages, and the European Heart Journal article.
Noncardiac surgery risk categories
The guideline includes a table that classifies noncardiac surgeries into three groups, based on the associated 30-day risk of death, MI, or stroke:
- Low (< 1%): breast, dental, eye, thyroid, and minor gynecologic, orthopedic, and urologic surgery.
- Intermediate (1%-5%): carotid surgery, endovascular aortic aneurysm repair, gallbladder surgery, head or neck surgery, hernia repair, peripheral arterial angioplasty, renal transplant, major gynecologic, orthopedic, or neurologic (hip or spine) surgery, or urologic surgery
- High (> 5%): aortic and major vascular surgery (including aortic aneurysm), bladder removal (usually as a result of cancer), limb amputation, lung or liver transplant, pancreatic surgery, or perforated bowel repair.
The guidelines were endorsed by the European Society of Anaesthesiology and Intensive Care. The guideline authors reported numerous disclosures.

The European Society of Cardiology guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery have seen extensive revision since the 2014 version.
They still have the same aim – to prevent surgery-related bleeding complications, perioperative myocardial infarction/injury (PMI), stent thrombosis, acute heart failure, arrhythmias, pulmonary embolism, ischemic stroke, and cardiovascular (CV) death.
Cochairpersons Sigrun Halvorsen, MD, PhD, and Julinda Mehilli, MD, presented highlights from the guidelines at the annual congress of the European Society of Cardiology and the document was simultaneously published online in the European Heart Journal.
The document classifies noncardiac surgery into three levels of 30-day risk of CV death, MI, or stroke. Low (< 1%) risk includes eye or thyroid surgery; intermediate (1%-5%) risk includes knee or hip replacement or renal transplant; and high (> 5%) risk includes aortic aneurysm, lung transplant, or pancreatic or bladder cancer surgery (see more examples below).
It classifies patients as low risk if they are younger than 65 without CV disease or CV risk factors (smoking, hypertension, diabetes, dyslipidemia, family history); intermediate risk if they are 65 or older or have CV risk factors; and high risk if they have CVD.
In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:
First, recommendations for preoperative ECG and biomarkers are more specific, he noted.
The guidelines advise that before intermediate- or high-risk noncardiac surgery, in patients who have known CVD, CV risk factors (including age 65 or older), or symptoms suggestive of CVD:
- It is recommended to obtain a preoperative 12-lead ECG (class I).
- It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
- It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).
However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).
