118: Comparing twin and triplet gestations: how much added risk with a third fetus?

The continued rise of multiple gestations is linked to the widespread use of assisted reproductive technologies (ART). The aim of this study is to quantify the added risk to mothers and neonates with triplet gestation versus twin gestation. Retrospective review of the electronic database created by the Consortium of Safe Labor, reflecting labor and delivery information from 12 clinical centers (19 hospitals) from 2002-2008. All twin and triplet gestations with complete data, liveborn infants and delivery greater than 24 weeks were included. Maternal morbidity was analyzed using univariate and multivariate analysis. Serious neonatal outcomes were compared via analysis of variance (ANOVA). Fetuses were matched by birth order for analysis. Significance was p
