Do adhesions at repeat cesarean delay delivery of the newborn?

OBJECTIVE: We sought to assess whether the presence and severity of adhesions at first repeat cesarean delivery are associated with delayed delivery of the newborn. STUDY DESIGN: We conducted secondary analysis of a prospective cohort of women undergoing first repeat cesarean. Severity and location of adhesions were reported by surgeons immediately postoperatively. We compared adhesion density scores with delivery data. RESULTS: Of 145 women analyzed, 92 (63.5%) had adhesions and 53 (36.5%) did not. Mean incision to delivery time in women with adhesion scores >3 was 19.8 minutes, compared to 15.6 minutes with scores ≤3 (P=.04). More women with adhesion scores>3 remained undelivered at 30 minutes after incision compared to scores ≤3 (17.9% vs 5.1%; odds ratio, 7.6; 95% confidence interval, 1.6 -34.5), after controlling for potential confounders. CONCLUSION: Among women undergoing first repeat cesarean, severity of adhesions may delay delivery of the newborn. Study of techniques to reduce adhesions may be warranted to prevent delayed delivery at repeat cesarean.
