A Study of the Effects of Initiating Assisted Ventilation During a Period of Delayed Cord Clamping for Extremely Preterm Infants


About this study

The purpose of this study is to determine whether initiating breathing assistance prior to clamping the umbilical cord influences the occurrence of intraventricular (brain) hemorrhage in extremely preterm infants, compared to the standard care of starting ventilation assistance after cord clamping.
