Abstract

Objective: To determine the prevalence of risk factors associated with perinatal morbidity and mortality in twin pregnancy (TP).
Methodology: A retrospective study. It took 200 medical records of maternal, diagnosed with EG who visited the emergency department of obstetrics and gynecology at the Hospital Universitario de Santander (Level III) in the period 2008-2011. Related variables were collected from the mother (sociodemographic, gynecological and obstetric and risk factors). Prevalence was calculated (P) with confidence intervals of 95% (95%). The Stata statistical software used was 11.0.
Results: The prevalence of diagnosed TP chance was 78% (95% CI 71.6 to 83.5), the prevailing monocoronic-biamnotic placenta (P = 56% 95% CI 48.8 to 63.0) and presentation cephalic-breech (P = 41.5% 95% CI 34.6 to 48.7). Obstetric complications were more frequent preterm labor (P = 70.5% 95% CI 63.7 to 76.7), preeclampsia (P = 20.5% 95% CI 15.1 to 26.8) and premature rupture of membranes (P = 14.5% 95% CI 9.9 to 20.2). There were 21 TP per 1000 births between 2008 and 2011. The death of both babies was 2% and a 4.5% newborn. Most twins one (G1) (63.5%) and two (G2) (57%) had a weight between 1501 and 2499 gr. There were more G1 minute Apgar normal (63%) compared to G2 (49.0%).
Conclusion: The incidence of TP has remained relatively constant between 2008 and 2011. The twin mortality is low, most twins weigh less than 2500 grams and fetal distress is greater for twin two at one minute. Besides the twin pregnancy presents high levels of neonatal morbidity.
