“DO YOU UTILIZE VASOPRESSIN IN YOUR DIFFICULT CESAREAN DELIVERY SURGERIES?”
ROBERT L. BARBIERI, MD (EDITORIAL; NOVEMBER 2016)
Avoid uterine vessels when injecting vasopressin
Thank you for your recent editorial discussing using vasopressin in difficult cesarean deliveries. I am very interested in using vasopressin for our placenta previa cases.
I reviewed the Kato et al article that Dr. Barbieri referenced, and the authors note a risk of injecting vasopressin into a vessel.1 If you are injecting into the placental bed, how can you confirm you are not in a vessel? (When you withdraw, you will get some blood regardless.)

Dr. Barbieri responds
I agree with Dr. Garmel that we should avoid the intravascular injection of vasopressin. As I noted in the editorial, “I prefer to inject vasopressin in the subserosa of the uterus rather than inject it in a highly vascular area such as the subendometrium or near the uterine artery and vein.” Subserosal injection creates a depot bleb of vasopressin that is absorbed over a few minutes. You can visualize the reduced blood flow to the uterus following vasopressin injection because the uterus blanches and the diameter of the uterine vessels decreases significantly.
