BACKGROUND: Induction of labour (IOL) in low-risk nulliparas at 39 weeks reduces caesarean delivery. Multiparas with ripe cervixes typically have vaginal delivery within eight hours. Delivery at night and weekend are associated with higher maternal and neonatal mortality.
AIMS: To evaluate IOL in full-term multiparas with ripe cervixes to achieve delivery at normal working hours and improve maternal satisfaction.
METHODS: A randomised trial was performed in a tertiary hospital in Malaysia. Low-risk multiparas with ripe cervixes (Bishop score ≥6) were recruited at 38+4 -40+0 weeks, then randomised to planned labour induction at 39+0 weeks or expectant care. Primary outcomes were delivery during 'normal working hours' 09:00-17:00 hours, Monday-Friday and patient satisfaction by visual numerical rating scale.
RESULTS: For IOL (n = 80) vs expectant care (n = 80) arms respectively, primary outcomes of delivery at normal working hours was 27/80 (34%) vs 29/78 (37%), relative risk (RR) 0.9, 95% CI 0.5-1.7, P = 0.41, patient satisfaction was 8.0 ± 1.8 vs 7.8 ± 1.6, P = 0.41; presentation for spontaneous labour or rupture of membranes were 27/80 (34%) vs 70/79 (89%), RR 0.4, 95% CI 0.3-0.5, P
