The effect of twin-to-twin delivery time intervals on neonatal outcome for second twins

摘要

The objective was to examine the effect of twin-to-twin delivery intervals on neonatal outcome for second twins. This was a retrospective, hospital-based study, performed at a university teaching hospital in Western Sweden. Twin deliveries between 2008 and 2014 at ≥32?+?0?weeks of gestation, where the first twin was delivered vaginally, were included. Primary outcome was a composite outcome of metabolic acidosis, Apgar 30?min (p?< 0.0001). An association, but not necessarily a causality, between twin-to-twin delivery interval and primary outcome was seen. An upper time limit on twin-to-twin delivery time intervals may be justified. However, the optimal time interval needs further studies.
