Twin Vaginal Deliveries: Impact of Delivery Time Interval on Twin B
Abstract Background:A vaginal twin delivery is a natural commonplace occurrence, but which can sometimes present a concern which may require action. Recently, the delivery time interval has been recognized as a variable that can be helpful for its safe conduct.Objectives:To view the delivery time interval in an obstetric population undergoing a twin vaginal trial of labor in consecutive deliveries during a specified time period.Study Design:A retrospective observational cohort of twin vaginal trials of labor was investigated to view the delivery time interval and its association with other factors, such as birth weights and the need for cesarean delivery of the second twin. The twin deliveries were divided into 2 groups, those with a delivery time interval of ≤ 30 minutes (Group A) and those with a delivery time interval of > 30 minutes (Group B), in a single institution.Results:No perinatal outcome difference was found between Group A (248 patients) or Group B (72 patients). However, 13 patients in Group B required a cesarean birth for a safe delivery, and 3 patients in Group A. The birth weight difference between each Baby A and Baby B varied according to the delivery time interval. Conclusion:The delivery time interval for vaginal twin deliveries may be useful to predict the need for a cesarean delivery of the second twin. The birth weight difference between Baby A and Baby B may be responsible for this finding.
