The objective of this study was to determine the mortality risk related to hypothermia at the moment of admission and other factors such as clinical and geographical related to the transportation of the newborns admitted to the Instituto Materno Infantil de Pernambuco IMIP from 8 March to 11 June 2000. A prospective study involving 320 newborns arriving from home or health centres was carried out. Babies that were dead on arrival or subsequently transferred to other units were excluded. The risk of death was determined according to exposure to hypothermia and other types of exposure, using logistical regression. The risk of death was higher (RR = 3.09; CI = 2.15-4.43) in the group exposed to moderate hypothermia (temperature between 32.5 degrees C and 35.99 degrees C) than in the non-exposed group (temperature equal to or greater than 36.00 degrees C). The relative risk of death was also higher for newborns with a weight of less than 2500 g, that were less than 1 day old, respiratory distress syndrome, premature babies or with congenital malformations, that had used oxygen and/or intravenous infusion during transit, that came from the interior and that had travelled more than 150 km. In the final result of the multivariate analysis, sepsis ('adjusted' RO = 6.23; 95% CI = 5.66-6.80), respiratory distress syndrome ('adjusted' RO = 5.28; 95% CI = 5.03-5.59), moderate hypothermia ('adjusted' RO = 3.49, 95% CI = 3.18-3.81), and distance undertaken greater than 50 km ('adjusted' RO = 2.39; 95% CI = 2.14-2.63) remained. Hypothermia on admission showed itself to be an important and independent risk factor for neonatal death.
OBJETIVOS: conhecer a prevalência de defeito de fechamento do tubo neural (DFTN) em crianças nascidas na maternidade do Centro de Atenção à Mulher do Instituto Materno Infantil Prof. Fernando Figueira (IMIP) no período de 2000 a 2004. MÉTODOS: estudo descritivo, do tipo corte transversal, cujos dados foram coletados de um banco de dados do Sistema de Informações sobre Nascidos Vivos do qual foram selecionados todos os registros de recém-nascidos com malformação fetal. A partir daí selecionaram-se os recém-nascidos com DFTN ocorridos no período considerado. RESULTADOS: entre os 24.964 nascimentos, foram registrados 709 recém-nascidos apresentando alguma malformação ao nascer. Ao se considerar apenas os recém nascidos com DFTN, observaram-se 124 registros, representando uma prevalência de 0,5% entre nascimentos naquele período. Os recém-nascidos com DFTN apresentaram características semelhantes aos recém-nascidos com malformações, de uma forma geral. A maioria (68,5%) desses recém-nascidos era de parto cesariano e 37,7% apresentaram baixo peso ao nascer. CONCLUSÕES: a prevalência de DFTN entre os nascimentos registrados no Centro de Atenção à Mulher do Instituto Materno Infantil Prof. Fernando Figueira foi elevada (5/1000 nascimentos) e isso, provavelmente é reflexo do fato de a maternidade ser referência para gestações de alto-risco.
