“…In line with previous studies that evaluated waiting 4-24 h after amniotomy, [3][4][5][6][7][8]10 we found that women desiring a 'short delay' after an amniotomy may reduce their likelihood of needing oxytocin without significantly prolonging labour. Parous women and those with a more favourable cervix during amniotomy were more likely to avoid oxytocin, which may assist informed decision-making.…”

“…2 Not all women choose to commence oxytocin immediately after amniotomy, and most will labour eventually. In randomised controlled trials, [3][4][5][6] most women who wait after amniotomy are in established labour within 24 h and do not require oxytocin at any stage during labour. Waiting after amniotomy is associated with a significantly longer amniotomy-to-delivery interval.…”

During induction of labour (IOL), the optimal timing of oxytocin following amniotomy is unknown, with limited data to guide decision‐making. This study aimed to see whether a 2‐h delay after amniotomy before starting oxytocin during IOL reduced the use of oxytocin as well as other positive or negative impact. A propensity‐score‐matched cohort study assessed the maternal, neonatal and process outcomes of 1168 women (584 per group) comparing immediate oxytocin to a 2‐h delay (‘wait’) after amniotomy. Women who waited were significantly less likely to receive oxytocin (61.2 vs 100%, P < 0.001) but more likely to receive antibiotics (14.7 vs 10.3%, P = 0.021), to be delivered by caesarean section (20.0 vs 14.6%, P = 0.013) and to be exclusively breastfeeding during discharge (77.2 vs 71.2%, P = 0.019). These findings provide further information for women and caregivers regarding the risks and benefits of a short delay before starting oxytocin.

“…2 Labor occurs within 24 hours of amniotomy for labor induction in 90.1% of women. 3 However, a Cochrane review concludes that data are lacking about the value of amniotomy alone for induction of labor, but there remain clinical scenarios in which amniotomy alone may be desirable and appropriate and this method is worthy of further research. 4 Another Cochrane review states that amniotomy and oxytocin infusion can induce labor, but the optimal timing of oxytocin infusion after amniotomy is not known.…”

Background Induction of labor in women with a previous cesarean section (CS) is associated with increased rates of uterine rupture and failed attempt for vaginal delivery. Prostaglandins use is contraindicated in this population, limiting available options for cervical ripening. Objective To evaluate the efficacy and safety of artificial rupture of membranes (AROM) as a mode of Induction of labor (IOL) in women with a previous cesarean section. Methods A retrospective cohort study conducted in a single tertiary care center between January 2015 and October 2020. Women with one previous cesarean section and a current singleton term pregnancy requiring IOL, with an unfavorable cervix, were included. The primary outcome was a successful vaginal delivery (VBAC); secondary outcomes were rates of chorioamnionitis, uterine rupture and low Apgar score (< 7). Results Of the 665 women who met the inclusion criteria, 492 (74%) did not receive subsequent oxytocin and 173 (26%) did. There were significant differences in the baseline characteristics between these two groups, including maternal age, cervical dilation at presentation, parity, and a history of a previous VBAC. Among women who were induced solely by AROM the rate of a successful TOLAC was higher (81.3% vs 73.9%), total time of IOL was shorter (mean 8.7 h vs.16.1 h) and the risk of chorioamnionitis was lower (7.3% vs 18.4%). When subdividing the women who received oxytocin into early (< 12 h after AROM) vs late (> 12 h after AROM) administration, there were no significant changes in the rates of successful VBAC or of chorioamnionitis. Conclusion AROM as a single mode of IOL in women with a previous CS is a safe and efficient practice with high rates of successful VBAC. When spontaneous labor does not develop, there is no advantage to delay the administration of oxytocin.
