Abstract

OBJECTIVE: To estimate neonatal morbidity and delivery outcomes according to planned mode of delivery in twin pregnancies with active second-stage management. METHODS: This was an historic cohort of twin pregnancies delivered in one practice between June 2005 and September 2009 using a strict protocol of second-stage management, including breech extraction of a second noncephalic twin and internal version of a nonengaged cephalic second twin followed by breech extraction. Primary outcome was a 5-minute Apgar score less than 7 for twin B. Secondary outcomes were 5-minute Apgar score less than 7 for twin A and 1-minute Apgar score less than 7 and arterial cord pH below 7.20 for each twin. Results: A total of 287 twin pregnancies were included. There were 157 patients (54.7%) in the planned cesarean group and 130 patients (45.3%) in the planned vaginal delivery group. There was no significant difference in the rates of twin B having a 5-minute Apgar score lower than 7 or an arterial cord pH below 7.20. Among the patients in the planned vaginal delivery group, the cesarean delivery rate was 15.4%. No patients had a vaginal delivery of twin A followed by cesarean delivery of twin B. Among the patients in the planned vaginal delivery group, patients who had a successful vaginal delivery were more likely to be younger (31.56±6.6 compared with 36.88±6.1 years, P=.001) and were more likely to have a prior vaginal delivery (47.3% compared with 15.0%, P=.007). Conclusion: Planned vaginal delivery of twin pregnancies seems to be associated with neonatal outcomes similar to those with planned cesarean delivery. Active second-stage management is associated with good neonatal outcomes and a low risk of combined vaginal-cesarean delivery.
