A Novel Approach to Teaching Placement of a B-Lynch Suture: Description of Technique and Validation of Teaching Model

摘要

IntroductionPostpartum hemorrhage is a major cause of maternal morbidity and mortality throughout the world and uterine atony is the leading cause of postpartum hemorrhage. The B-Lynch brace suture is a fertility-sparing approach to treating intractable uterine atony at the time of cesarean delivery. However, many obstetricians lack confidence to perform this procedure, which they may not have performed during residency. In order to train all residents to perform the B-Lynch brace suture, we developed a realistic model by using a flank steak to imitate a gravid uterus.MethodsA convenience sample of obstetrics-gynecology faculty and residents at different levels of training at a single large hospital participated in this pilot project. Each physician reported self-perceived understanding of and confidence in performing the B-Lynch procedure before and immediately after practicing the technique using the flank-steak model, via a Likert-type survey (scale 1??=??low, 5??=??high). A Wilcoxon matched-pairs signed rank test was used to compare the before and after responses.ResultsThirty-four participants completed the flank-steak model training and pretraining/posttraining surveys. The median score (range) for self-perceived understanding was 4 (2–5) and increased to 5 (4–5) ( P ?
