Effects of Delayed Cord Clamping in Very Low Birth Weight (VLBW) Infants
The purpose of this study was to see if a brief delay in cord clamping for 30 to 45 seconds
would result in higher hematocrit levels, fewer transfusions, healthier lungs, and better
motor function at 40 wks and 7 months of age.
would result in higher hematocrit levels, fewer transfusions, healthier lungs, and better
motor function at 40 wks and 7 months of age.
When cord clamping is delayed at birth or the cord is milked, infants receive a placental
transfusion of 10-15 mL/kg during the first few minutes of life. This additional blood
improves hemodynamic stability and may reduce the risk of intraventricular hemorrhage (IVH)
and the vulnerability of infants to inflammatory processes. This blood also contains stem
cells that are important in repairing tissue and building immunocompetence.
The current randomized controlled trial prospectively tested the effects of DCC for 30-45
seconds followed by 1 cord milking with the aim of confirming our prior work and providing
long-term follow-up. Our a priori hypotheses were that DCC would reduce the incidence of
IVH, LOS, and result in better motor function at 18-22 months.
