Abstract

Purpose: The "en caul" cesarean section (CS) is a method to keep the amnion intact during CS. This amnion protection effect may have benefits in preterm twin pregnancy. This study aimed to explore the benefits and risks of this method in preterm twin pregnancy.

Methods: This study is a retrospective analysis of preterm twin pregnancies underwent CS in West China Second University Hospital of Sichuan University from January 2011 to December 2022. Data on maternal and fetal outcomes were collected. Univariable analyses and multivariate logistic regression analyses were applied. The level of significance was set at p < 0.05.

Results: A total of 182 patients were included (90 in the "en caul" group, 92 in the conventional group). "en caul" CS was associated with lower incidence for respiratory distress (aOR 0.47, 95% CI 0.25-0.88, for the first fetus; aOR 0.42, 95% CI 0.21-0.82, for the second fetus). This method was proved to have beneficial effects in improving the Apgar scores at 1st minute and reducing the mechanical ventilation rate in the second neonates (aOR 0.41, 95% CI 0.19-0.88).

Conclusion: "En caul" CS is an easy and safe technique to perform during CS for preterm twin pregnancy. The efficacy and safety of this method could be tested by future studies with larger sample size.
