Abstract

Background: This study compared neonatal outcome and maternal complications in multiple pregnancies after assisted reproductive technologies (ART) to spontaneous pregnancies. Materials and Methods: In this cross-sectional study, we reviewed medical records of 190 multiple pregnancies and births conceived by ART or spontaneous conceptions between 2004 and 2009 in Women Hospital. Obstetric history and outcomes were recorded and compared between these two groups. SPSS version 13 was used for data analysis. The results were analyzed using student’s t test, chi square and logistic regression (p<0.05). Results: There were 106 deliveries from spontaneous conceptions and 84 that resulted from ART. Parity history and mode of delivery significantly differed between the two groups (p<0.001). The ART group had significantly higher preterm labor and premature rupture of membranes (PROM) whereas pregnanc-induced hypertension (PIH) was higher in the spontaneous group (p=0.01). Newborn intensive care unit (NICU) admission, duration of hospitalization, still birth and low gestational age were significantly higher in the ART group while neonatal jaundice was higher in the spontaneous group. Logistic regression analysis by considering neonatal complications as the dependent variable showed that respiratory distress syndrome (RDS), NICU admission and Apgar score were independent predictors for neonatal complications. Conclusion: Obstetric and neonatal outcomes must be considered in multiple pregnancies conceived by ART. © 2015, Royan Institute (ACECR). All rights reserved.
