Maternal postpartum complications according to delivery mode in twin pregnancies.

ABSTRACT

OBJECTIVE: We aimed to examine maternal postpartum complications of twin deliveries according to mode of delivery and investigate the associated risk factors. METHODS: This was a retrospective cohort review of twin pregnancies with delivery after 26 weeks at a tertiary teaching hospital (1993-2008). The rates of maternal postpartum complications were compared among vaginal, elective cesarean and emergency cesarean deliveries. Significant predictors of complications were investigated with stepwise regression analysis and relative risks were calculated. RESULTS: A total of 90 complications were observed in 56/817 (6.9%) deliveries 7/131 (5.3%) vaginal, 10/251 (4.0%) elective cesarean and 39/435 (9.0%) emergency cesarean deliveries. Significant predictors included high-risk pregnancy, gestational age at birth and delivery mode. The occurrence of complications was significantly increased in emergency compared to elective cesarean deliveries (RR=2.34). CONCLUSIONS: Maternal postpartum complications in twin pregnancies are higher in emergency compared to elective cesarean deliveries and are also related to preexisting complications and earlier gestational age at delivery.
