[Perinatal risk factors and correlation with the incidence of early peri-and intraventricular hemorrhage in neonates with a birthweight under 1500 g].

The goal of this article is to know the incidence of early periventricular-intraventricular hemorrhage (EPIVH) and the risk factors that contribute to its development in low birth weight infants of less than 1500 g. Ultrasonographic brain scan was performed in Newborns with perinatal risk factors with birth weight less than 1500 grams, gestational age less than 34 weeks, and extrauterine age less than 24 hours at the time of the brain scan. 91 patients met inclusion criteria, 48 (52.7%) had EPIVH. 27 (29.7%) had periventricular ecodensities and 16 (17.6%) had a normal brain scan. Statistical significative differences were found between group with EPIVH and patients with normal brain scan respect to birth weight, gestational age, and Apgar score at 5 minutes. Perinatal risk factors that were significative to EIVH more than grade I were, premature rupture of membranes, vaginal delivery and Apgar score of 0-2 at 1 minute. The most relevant risk factors to EIVH grade III and cerebral infarction were twin pregnancy, vaginal delivery, breech presentation, obstetric trauma and urinary tract infection. Our incidence of EIVH is according to literature. cesarean section must be considered to diminish neonatal neurological morbidity and mortality.
