Umbilical cord clamping in preterm infants.

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.
