ABSTRACT

Introduction: The twin pregnancy is considered a high risk entity. In our institution, the percentage of live newborns due to double pregnancies varies between 4.8 and 6.5%. Multiple pregnancies have a greater impact on health systems due to high rate of complications. Objective: To describe the maternal and neonatal characteristics of twin pregnancies at the Instituto Nacional de Perinatología, and determine differences in morbidity between the first and second twin. Material and Methods: The study was conducted in the all newborns products of twin pregnancies from January 1st 2007 to December 31st 2008 were included. Descriptive statistics by means of tables and analytical statistics was used to compare the twins. Results: A total of 654 newborn cases from 327 twin pregnancies were included. Spontaneous pregnancy was found in 92%. Preeclampsia was the most common cause of maternal mortality presented in 14.2% of the pregnancies. Intrauterine growth restriction was found in 55.2% and prematurity in 54.9%. No statistical differences were observed in the morbidity between the first and the second twin. Conclusions: Due to an increased maternal and fetal morbidity and mortality observed in twin pregnancies, measures to prevent complications most be applied during the perinatal period.
