Asfixia perinatal associada à mortalidade neonatal precoce: estudo populacional dos óbitos evitáveis

Abstract

Perinatal asphyxia associated with early neonatal mortality: populational study of avoidable deathsResults: During the three years, 1.71 deaths per 1,000 live births were associated with perinatal asphyxia, which corresponded to 22% of the early neonatal deaths. From the 2,873 avoidable deaths, 761 (27%) occurred in São Paulo city; 640 (22%), in the metropolitan region of São Paulo city; and 1,472 (51%), in the countryside of the state. In the first two regions, deaths were more frequent in public hospitals, among newborns with gestational age of 36 weeks or less, and among babies weighing less than 2500g. In the countryside, mortality was more frequent in philanthropic hospitals, in term newborns and in neonates weighing over 2500g. Most of these neonates were born during daytime in their hometown and died at the same institution in which they were born within the first 24 hours after delivery. Meconium aspiration syndrome was related to 18% of the deaths.Conclusions: Perinatal asphyxia is a frequent contributor to the avoidable early neonatal death in the state with the highest gross domestic product per capita in Brazil, and it shows the need for specific interventions with regionalized focus during labor and birth care.

Extremes of maternal age and child mortality: analysis between 2000 and 2009

“…The high proportions of death by perinatal conditions are warning signs, as they may indicate early termination of pregnancy or intrauterine retarded growth, the result of inadequate prenatal care 2123 , 27 As for congenital abnormalities, studies indicate a higher incidence among women of advanced age,7 , 10 , 12 , 18 , 21 , 23 corroborating the findings of this study. In contrast, external causes were more evident in the children of adolescent mothers, a fact of concern as they are preventable events that may be associated with the lack of preparedness on the part of young mothers to care for their children.…”

“…As altas proporções de óbito por afecções perinatais constituem sinal de alerta, pois podem indicar interrupção precoce da gravidez ou crescimento intra-uterino retardado, resultado de acompanhamento pré-natal inadequado 2123 , 27 Quanto às anomalias congênitas, estudos apontam maior ocorrência entre mulheres com idade avançada,7 , 10 , 12 , 18 , 21 , 23 corroborando os achados deste estudo. Ao contrário, as causas externas foram mais evidentes nos filhos das adolescentes, fato preocupante por ser um evento totalmente prevenível e que pode estar associado ao despreparo da jovem mãe para cuidar do filho.…”

Risk factors associated with the development of perinatal asphyxia in neonates at Hospital Universitario del Valle, Cali, Colombia, 2010-2011

“…Additionally, the lack of prenatal care or insufficient prenatal care with less than three visits during pregnancy showed a borderline association and was not significantly associated with the development of perinatal asphyxia among the infants in this study; however, in the literature, these factors have shown a clear relationship with poor prognosis of pregnancy (17,18).…”

Risk Factors for Perinatal Asphyxia in Newborns Delivered at Term

“…Studies in Scotland and Brazil corroborate the findings in maternal age because the age group is between 16 -34 years old and are primiparous. In this sense, although this range is considered low risk for complications during pregnancy and childbirth, it is believed that perinatal asphyxia in this segment of the population is a result of weakened actions related to monitoring of the pregnant woman hindering to detect the factors risk resulting in perinatal asphyxia [6] [7].…”
