Objective: The lack of obstetricians in Japan has prevented the implementation of a 24?hour delivery monitoring system for high-risk deliveries such as twin vaginal delivery at many obstetric facilities. To examine the outcomes of a 1-day trial of the vaginal delivery of twins at 36?37 weeks' gestation.
Methods: We induced the vaginal delivery of twins at 36?37 weeks' gestation of 256 women who provided consent between January 2007 and December 2016 using the following protocol: 1) administration of 0.5 mg oral prostaglandin E2 every 1 hour (maximum: 1.5 mg) in the morning; 2) intravenous administration of oxytocin and amniotomy in the afternoon; and 3) selection of caesarean delivery when vaginal delivery was not expected by evening. We examined their perinatal outcomes in a chart review.
Results: The completion rates of vaginal delivery in total, nulliparous, and multiparous women were 79%, 72%, and 84%, respectively. There were no cases of neonatal asphyxia. The total incidence of neonatal respiratory disorders was 2.1%, but there were no cases of persistent pulmonary hypertension. The total incidence of postpartum hemorrhage requiring transfusion was 2.7%.
Conclusion: The 1-day planned vaginal delivery of twins at 36?37 weeks' gestation appears valid and safe, and our findings suggest that it can be an option for the delivery of twins.
