[Neonatal outcome depending on the mode of delivery and fetal presentation in twin gestation]

A retrospective analysis of 301 twin deliveries managed at The Second Department of Obstetrics and Gynecology, Warsaw Medical Academy, from January 1, 1986 to December 31, 1995 was undertaken in order to investigate the impact of the mode of delivery and twin presentation on neonatal outcome. Vertex presentation of both twins was the most common with an incidence of 47.5% followed by vertex-non-vertex (27.6%) and nonvertex presentation of the first twin (24.9%). 186 (61.8%) patients delivered vaginally, while 115 (38.2%) women underwent caesarean section including 6 operations performed after the vaginal delivery of the first twin. In vertex presentation of the first twin and breech second twin there was no significant difference in neonatal outcome measured by 5-minute Apgar score and birth trauma incidence between second twins delivered vaginally and second twins delivered by caesarean section. Vaginal delivery with internal podalic version of the second twin in vertex-transverse presentations was related to increased risk of lower 5-minute Apgar score and increased risk of birth trauma occurrence compared to caesarean section. Time interval between vaginal delivery of twins had no significant impact on neonatal outcome.
