Objective: To assess the asphyxia-mortality relationship.Method: A case-control study involving all live births (NB) between 2005 and 2009 (N=9,535) with hospital records analysis based on stillbirths (cases) and live births (controls) for a 28-day period as regards weight, Apgar, survival and mortality cause. Cases and controls were compared by the Chi-square text (p< 0.05).Results: Out of 9,535 births there were 139 deaths, 58.3% in the first week, 3.6% for serious asphyxia and positive association between mortality and asphyxia, with significantly decreasing figures up to 2,000 g weight. In the < 1,000 g weight group, the asphyxia-mortality relationship was three times higher that that in the 1,000-1,500 g group and 35 times higher that that of the 3,000 g group. Among the 8-10 Apgar index group, mortality rate in low weight was twice that of the > 2,499 g children. The chi-square result for weight-mortality relationship was of 1252.24 (p< 0.0001) and for asphyxiamortality was of 626.46 (p< 0.0001). Asphyxia and prematurity were associated to the early neonatal death, and malformations and asphyxia were associated to late mortality. The death predictive value for Apgar < 4 varied according to weight from 62.74% for the < 1,000 g group to 5.5% for the > 3,000 g group. Asphyxia also correlated with lack of prenatal visits, preterm labor, normal childbirth and urinary infection.Conclusion: Perinatal asphyxia is associated with epidemiological as well as with delivery care, causes neonatal death and is associated with extreme low weight. |
