Perinatal mortality: associated risk factors. Regional Hospital of Huacho

Abstract

OBJECTIVES: To determine the rates and risk factors associated with perinatal mortality. DESIGN: Descriptive, analytical study, cross-sectional, case-control type. MATERIALS AND METHODS: 4413 medical records from the database the Perinatal Information System of births that occurred between January 1998 and December 1999 were reviewed in the institution. RESULTS: 4322 items heavier than 999 g or greater than 27 weeks was obtained; there were 42 stillbirths and 43 infants died before seven days. The perinatal mortality rate was 19.5% born of> 999 g> 27semanas; the rate of stillbirth (MFT) was 9.6% of births> 999 g> 27ff; the rate of early neonatal mortality (MNP) was 9.9% of live births> 999 g> 27ff. The most significant risk factors for MFT were third trimester bleeding (RR: 15), uneducated (RR: 5.1), grand multiparity (RR: 4.5) and without prenatal care (PNC) (RR: 3 4); the most common for the same damage were without CPN (n = 584) and only primary education (n = 624). The most significant risk factors for MNP were Apgar 0-3 at 5 minutes (RR: 86), Apgar 0-3 the first min (RR: 78), preterm delivery (RR: 62) and low birthweight (RR: 56); the most common for the same damage were low birth weight (n = 232), preterm birth (n = 205), Apgar 4-6 a first min (n = 162) and breech delivery (n = 141). CONCLUSIONS: Strategies to reduce the MFT have to address the problem of the absence of NPCs and have the means to recruit pregnant women with no education. Strategies to reduce the MNP have to look reduce frequency of low birth weight, reduce somewhat the incidence of Apgar low and very low and, above all, optimize resuscitation measures.
