Objective: The aim of our study was to define he best delay for management of spontaneous rupture of the membranes at term.
Materials and methods: We conducted a prospective multicentric study in western France defining 3 groups of expectancy (6, 12 and 24 hours) to assess obstetrical, neonatal and maternal outcomes.
Results: We included 713 patients. There was no significant difference in neonatal and maternal morbidity between the 3 groups. The rate of cesarean section was statistically higher in the 6-hour group (12%). There was no statistical difference between 12 and 24 hours but the rate was lower in the 12-hour group (5.5 versus 7.9%).
Conclusion: Based on our findings and a review of the literature, we have decided that in cased of premature rupture of the membranes at term, a 12 hour delay is best. At most two prostaglandin maturations can be performed in unfavorable cervixes.
