ABSTRACT

Introdução: O objetivo do estudo foi determinar a prevalência da Doença da Membrana Hialina (DMH) em prematuros de baixo peso e suas principais complicações. Métodos: Foi realizado um estudo descritivo do tipo série de casos. A população em estudo foram 34 prematuros com peso inferior a 1500 gramas e/ou idade gestacional inferior a 32 semanas nascidos no período de julho de 2010 a julho de 2011 no Hospital Universitário de Canoas/RS. Resultados: Pré-eclâmpsia e trabalho de parto prematuro foram as causas mais frequentes de parto pré-termo. DMH ocorreu em todos os recém-nascidos com peso inferior a 1000 gramas. Em prematuros com peso ao nascer entre 1001 e 1250 gramas e 1251 e 1499 gramas, a prevalência da DMH foi de 71,4% e 44,4%, respectivamente. A complicação da DMH mais frequente foi a persistência do canal arterial. Conclusões: A prevalência da DMH encontrada foi de 100% nos prematuros com peso até 1000 gramas e de 71,4% nos RNs com peso entre 1001g e 1250g. Nos prematuros com peso de 1251g a 1499g, a prevalência foi de 44,4% (AU)


Introduction: The aim of the study was to determine the prevalence of hyaline membrane disease (HMD) in preterm, low birth weight infants and its major complications. Methods: A descriptive study of the case series was conducted. The study population were 34 preterm infants weighing less than 1500 grams and/or gestational age less than 32 weeks born from July 2010 to July 2011 at the University Hospital of Canoas, RS. Results: Pre-eclampsia and preterm labor were the most frequent causes of preterm birth. HMD occurred in all newborns weighing less than 1000 grams. In premature infants with birth weights between 1001 and 1250 grams and 1251 grams and 1499, the prevalence of DMH was 71.4% and 44.4%, respectively. The most frequent complication of DMH was the persistent ductus arteriosus. Conclusions: The prevalence of DMH was 100% in preterm infants weighing up to 1000 grams and 71.4% in newborns weighing between 1001g to 1250g. In premature infants weighing 1251g to 1499g, the prevalence was 44.4% (AU)

ABSTRACT

Se examinó la historia y el estado actual del conocimiento sobre el sistema surfactante pulmonar endógeno, enfatizando en la composición bioquímica y sus funciones biológicas al nivel pulmonar; así como en las fuentes y vías de obtención de los surfactantes exógenos; algunos productos que han logrado introducirse con éxito en la práctica clínica y otros que están en fases avanzadas de su ciclo de obtención y evaluación. Aborda las metas de la investigación en este campo.


The history and present state of the knowledge about the endogenous pulmonary surfactant system was examined, making emphasis on the biochemical composition and its biological functions at the lung level, as well as on the sources and ways of obtention of the exogenous surfactants, on some products that have been successfully introduced into the medical practice and on others that are at advanced stages of their cycle of obtention and evaluation. It also approaches the goals of research in this field.
