Objective: To evaluate adjunctive membrane sweeping in Foley catheter labor induction for induction-to-delivery interval and maternal satisfaction in women with one previous cesarean delivery.Methods: This randomized trial was conducted from June to December 2020. Sixtythree women at term with one previous cesarean delivery, planned for labor induction with unripe cervixes (Bishop score ≤5), singleton, cephalic presentation with intact membranes and reassuring pre-induction fetal heart rate tracing were recruited.Women were randomized to membrane sweeping or no sweeping before Foley catheter induction of labor. Primary outcomes were induction-to-delivery interval (in hours) and maternal satisfaction with the birth process (assessed by a Visual Numerical Rating Scale 0-10).Results: Induction-to-delivery intervals (hours), mean ± standard deviation, were 25.2 ± 9.8 versus 27.0 ± 9.4 (P = 0.463), and maternal satisfactions on birth process, median (interquartile range), were 8 (7-8) versus 8 (7-9) (P = 0.170), for the adjunctive membrane sweeping with Foley catheter versus Foley catheter alone arms, respectively. Cesarean delivery rates were 22/32 (69%) versus 19/31 (61%) (relative risk 1.12, 95% confidence interval 0.78-1.62; P = 0.603), and insertion-to-catheter removal intervals, median (interquartile range), were 15 (6.3-21.0) versus 19 (11.0-24.0) hours (P = 0.065) for membrane sweeping with Foley catheter versus Foley catheter arm, respectively.
Conclusion:Membrane sweeping before Foley catheter labor induction in women with one previous cesarean delivery and unfavorable cervixes did not improve induction-to-delivery interval and maternal satisfaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
