ObjectiveThe 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.MethodsWe 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.ResultsThe 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%.ConclusionThe 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.
Key Clinical Message
In the current case of fetomaternal hemorrhage with reduced fetal movements, the findings of cardiotocography (CTG) seemed to be indicating reassuring fetal status; however, a late deceleration and sinusoidal heart rate (SHR)‐like findings were observed following a weak uterine contraction. Altogether, this case indicates that the presence of reduced fetal movements may precede the appearance of SHR patterns on CTG in cases of chronic fetomaternal hemorrhage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
