Neonatal outcomes according to actual delivery mode after planned vaginal delivery in women with a twin pregnancy.

Objective: To compare, in women with twin pregnancy with the first twin in cephalic position, neonatal morbidity and mortality rates after actual 1) Vaginal delivery (VD) both twins versus 2) unplanned Cesarean Delivery (CD) of both twins and 3) after VD of twin A and CD of twin B (combined delivery).

Study Design: We describe a nationwide cohort study of women pregnant with twins who planned to deliver vaginally between 32 - 41 weeks with the first twin in cephalic position, between 2000-2012 in the Netherlands. We used multivariate logistic regression analysis to compare neonatal morbidity and mortality according to actual mode of delivery, overall, and for preterm and term groups separately.

The risk of intrapartum/neonatal mortality and morbidity following birth at 37 weeks of gestation: a nationwide cohort study.

Objective: To assess intrapartum/neonatal mortality and morbidity risk in infants born at 37 weeks of gestation compared with infants born at 39-41 weeks of gestation.

Design: Nationwide cohort study.

Setting: The Netherlands.

The impact of mode of delivery on the outcome in very preterm twins.

Studies on the optimal mode of delivery in women with a twin pregnancy <32 weeks are scarce. We studied the effects of the mode of delivery on perinatal and maternal outcomes in very preterm twin pregnancy. Population-based cohort study including all women with twin pregnancy who delivered very preterm (26-32 weeks of gestation) in the Netherlands between January 2000 and December 2010.

Perinatal outcomes according to the mode of delivery in women with a triplet pregnancy in The Netherlands.

In women with a triplet pregnancy, there is debate on the preferred mode of delivery. We performed a nationwide cohort study to assess the impact of mode of delivery on perinatal outcome in women with a triplet pregnancy. Nationwide cohort study on women with a triplet pregnancy who delivered between 26 + 0 and 40 + 0 weeks of gestation in the years 1999-2008.

Comparison of planned caesarean delivery and planned vaginal delivery in women with a twin pregnancy: A nation wide cohort study.

Objective: To compare, in women with twin pregnancy with the first twin in cephalic position, neonatal morbidity and mortality rates after planned caesarean delivery (CD) versus planned vaginal delivery (VD).

Study Design: A nationwide cohort study on women pregnant with twins and the first child in cephalic position, who delivered between 32 + 0-41 + 0 weeks between 2000 and 2012 in the Netherlands, using multivariate logistic regression analysis to compare neonatal morbidity and mortality according to planned delivery mode, and looking at subgroups 32 + 0-36 + 6 and 37 + 0-41 + 0 weeks.

Results: We included 21,107 women, of whom 1384 (6.
