Abstract:
Preterm induction of labor can be necessary for maternal and fetal wellbeing. Duration of cervical ripening balloon (CRB) use has been studied only in term inductions. Our study investigated duration of time for CRB expulsion and vaginal delivery in preterm inductions of labor. METHODS: This was a single-institution retrospective cohort study of preterm ( 〈 37 weeks) and term (≥37 weeks) inductions with CRB between 2010 and 2021. Cesarean deliveries were excluded. Primary outcome was insertion to expulsion time (IET) of CRB. Secondary outcomes included induction to delivery time (IDT), cervical dilation after expulsion, and misoprostol and Pitocin use. Institutional review board approval was obtained prior to the study. RESULTS: A total of 98 patients with vaginal delivery after preterm CRB use were identified and matched 1:1 on baseline characteristics to patients with vaginal delivery after term CRB use. Mean IET was significantly shorter for term CRB than for preterm induction (mean 7.2±3.09 hours versus 8.5±3.38 hours; P =.004). Mean IDT was significantly shorter for term CRB than preterm CRB induction (18.4±7.6 hours versus 22.5±9.01 hours; P 〈 .001). Increased use of misoprostol, Pitocin, and second CRB were noted among the preterm cohort compared to the term cohort. Among term patients, more CRB placement at start of induction and greater cervical dilation post-balloon were found in comparison to preterm patients. CONCLUSION: Among patients undergoing preterm induction, longer IET, longer IDT, and increased interventions should be expected. Different standards for labor management should be considered for achieving vaginal delivery in preterm inductions.
