RESUMO

Introducción. Con el propósito de determinar la efectividad del surfactante bovino (SB) para el tratamiento del síndrome de dificultad respiratoria (SDR) en recién nacidos prematuros (RNP), se realizó una revisión sistemática y meta-análisis. Métodos. Se incluyeron ensayos clínicos aleatorizados (ECA) donde se comparó SB con placebo. Las variables de desenlace fueron: mortalidad, morbilidad, días de ventilación mecánica (VM) y de estancia hospitalaria. Los ECA publicados hasta el 2010 se identificaron en Medline, EMBASE y la Colaboración Cochrane. La selección de los ECA fue por pares. En el meta-análisis se calculó riesgo relativo (RR) y diferencia de medias ponderada (DMP), con intervalos de confianza al 95% (IC95%). Resultados. De 865 títulos y resúmenes, se revisaron 89 artículos en extenso y se seleccionaron 12 ECA. El SB se mostró efectivo en cuatro variables: mortalidad (RR 0.73, IC95% 0.60-0.88, P =0.001), neumotórax (RR 0.41; IC95% 0.33-0.51, P <0.0001), enfisema intersticial pulmonar (RR 0.45; IC95% 0.36-0.56, P <0.0001) y días de VM (DMP -9.57; IC95% -16.58, -2.56, P =0.007). Para otras, como displasia broncopulmonar, enterocolitis necrosante, hemorragia intraventricular o alteración del desarrollo neurológico, no se determinó ventaja con SB. Conclusiones. En RNP, el uso de SB es efectivo al disminuir la mortalidad, la frecuencia de neumotórax y enfisema intersticial pulmonar, así como el tiempo de VM y, posiblemente, el de estancia hospitalaria.


Background. In order to evaluate the effectiveness of the bovine surfactant (BS) for the treatment of newborns with respiratory distress syndrome (RDS), we performed a systematic review and meta-analysis. Methods. Randomized-controlled trials (RCT) assessing the BS in comparison with placebo for the treatment of prematures with RDS were included. Outcome measures evaluated were: mortality, morbidity, days on mechanical ventilation (MV) and length of hospitalization. RCT published until 2010 were obtained from Medline, EMBASE and Cochrane Collaboration. Selection of included studies was based on a peer-review process. For the meta-analyses, relative risk (RR) and weighted mean differences (WMD) were calculated, with 95% confidence intervals (95%CI). Results. From 865 titles and abstracts obtained, 89 papers were reviewed and 12 RCT were selected. Among the outcome measures assessed, BS was shown to be effective in only in four: mortality (RR 0.73, 95% CI 0.60-0.88, p =0.001), pneumothorax (RR 0.41; 95% CI 0.33-0.51, p <0.0001), pulmonary interstitial emphysema (RR 0.45; 95% CI 0.36-0.56, p <0.0001) and on days of MV (WMD -9.57; 95% CI -16.58 to -2.56, p =0.007). However, we did not find any positive effect on bronchopulmonary dysplasia, necrotizing enterocolitis, intraventricular hemorrhage or abnormal neurological development. Conclusions. In newborns with RDS, bovine surfactant is effective regarding mortality, pneumothorax, and pulmonary interstitial emphysema, as well as on decrease in the length of MV and possibly on length of hospitalization.
