ABSTRACT
Background: Perinatal period begins at 22 gestational weeks and ends seven days after birth. Perinatal mortality is an important quality indicator of the obstetric and pediatric care available, and representative of the population’s health service.Objective: to know fetal, early neonatal, and perinatal dead rates, and them main mortality causes.
Patients and methods: Descriptive and retrospective study at IMSS’s no. 32 UMAE (Monterrey, Nuevo León, México), from January 2002 to December 2006. Mortality rates during fetal and perinatal, or neonatal periods, were estimated per 1,000 births or 1,000 live born, respectively.
Results: There were 1,681 deaths: 747 stillbirths and 934 neonatal. Two hundred and nineteen (29.3%) stillbirths had 22 to 27 gestational weeks, and 528 (70.6%) had 28. Three hundred and sixty neonatal deaths (38.5%) occurred before 27th gestational week, 320 (34.2%) between weeks 28th and 35th, and 254 (27.1%) after 36 weeks of pregnancy. Seven hundred and sixty four neonates died within 0 to 6 days of life, and 170 (18%) between seventh to 28th days of life. Fetal, neonatal, early neonatal, and late neonatal mortality rates were 7.2 in 1,000 births, 9.08 in 1,000 live born, 7.42 in 1,000 live born, and 1.65 in 1,000 births, respectively, and overall perinatal mortality rate was 14.58 in 1,000 births.
Conclusions: Stillbirth, early neonatal, and perinatal mortality rates of this study were under national mean. Main mortality causes (70%) were congenital defects and prematurity.
