They also noted the benefits that modality provides over other imaging techniques.
Marco Denina, MD, and colleagues from the pediatric infectious diseases unit at Regina Margherita Children’s Hospital in Turin, Italy, performed an observational study of eight children aged 0-17 years who were admitted to the hospital for COVID-19 between March 8 and 26, 2020. In seven of eight patients, the findings were concordant between imaging modalities; in the remaining patient, lung ultrasound (LUS) found an interstitial B-lines pattern that was not seen on radiography. In seven patients with pathologic ultrasound findings at baseline, the improvement or resolution of the subpleural consolidations or interstitial patterns was consistent with concomitant radiologic findings.
The authors cited the benefits of using point-of-care ultrasound instead of other modalities, such as CT. “First, it may reduce the number of radiologic examinations, lowering the radiation exposure of the patients,” they wrote. “Secondly, when performed at the bedside, LUS allows for the reduction of the patient’s movement within the hospital; thus, it lowers the number of health care workers and medical devices exposed to [SARS-CoV-2].”
One limitation of the study is the small sample size; however, the researchers felt the high concordance still suggests LUS is a reasonable method for COVID-19 patients.
There was no external funding for this study and the investigators had no relevant financial disclosures.
