Delayed umbilical cord clamping in premature neonates

Area of Science:

• Neonatal Medicine
• Perinatal Care
• Obstetrics

Background:

• Delayed umbilical cord clamping (DUCC) is associated with increased neonatal blood volume.
• The clinical outcomes of DUCC in premature neonates require further investigation.

Purpose of the Study:

• To compare the clinical outcomes of delayed umbilical cord clamping (45 seconds) versus early umbilical cord clamping in premature neonates.
• To assess the impact of DUCC on resuscitation needs, hematocrit levels, and transfusion rates in very low birth weight (VLBW) and low birth weight (LBW) infants.

Main Methods:

• A before-after study design comparing early and delayed umbilical cord clamping in singleton VLBW (401-1,500 g) and LBW (>1,500 g, <35 weeks gestation) neonates.
• Exclusion criteria included neonates requiring immediate major resuscitation.
• Primary outcomes included delivery room resuscitation, hematocrit, red cell transfusions, and Vermont Oxford Network outcomes.

Main Results:

• In VLBW neonates, DUCC was linked to reduced resuscitation, higher 1-minute Apgar scores, and elevated hematocrit.
• In LBW neonates, DUCC showed higher hematocrit without significant changes in resuscitation or Apgar scores.
• Regression analysis identified gestational age, birth weight, and DUCC as predictors of higher hematocrit and less resuscitation.

Conclusions:

• Delayed umbilical cord clamping is a safe procedure for singleton premature neonates.
• DUCC is associated with improved hematocrit levels and decreased need for resuscitation.
• No significant increase in neonatal morbidities was observed with delayed umbilical cord clamping.
