Abstract

For several years now, the survival of preterm infants has been increasing, which has shifted our concern to preterm infants born before 28 weeks of gestation in particular. The timing of umbilical cord clamping may lead to several disorders, especially when done early (10-15 seconds). In the last two decades, several investigations have shown the considerable benefits of delayed cord clamping (2-3 minutes). Delayed cord clamping has been practiced in obstetrics and neonatal care based on the recommendations made by scientific societies and in systematic reviews, which have provided solid evidence to support this practice in preterm infants. This review describes the most relevant articles from the last years, which strongly support the use of delayed cord clamping versus early cord clamping. In addition, this practice reduces the rate of severe disorders in preterm infants.

La prematuridad fue aumentando la supervivencia desde hace varios años, y eso produce, sobre todo, una preocupación en los prematuros nacidos antes de las 28 semanas de gestación. El tiempo del clampeo del cordón umbilical puede generar diversos trastornos, principalmente, cuando se realiza temprano (10-15 segundos). Ya desde hace 20 años, a través de varias investigaciones, se pudieron demostrar los notorios beneficios del clampeo demorado del cordón (de 2 a 3 minutos). Esta práctica fue instalada en la asistencia obstétrica y neonatal por las recomendaciones de sociedades científicas y de las revisiones sistemáticas, que señalaron las sólidas evidencias que apoyaban esta conducta para prematuros. En esta revisión, se describen los artículos más relevantes en los últimos años, que sustentan notoriamente la aplicación del clampeo demorado del cordón versus el clampeo temprano. Asimismo, esta práctica genera una disminución de los trastornos graves en prematuros.
