Objective |
To evaluate the effect of blood sampling from the placental end of the umbilical cord compared with initial blood sampling from neonates, on the need for first packed red blood cell transfusion in extremely preterm infants. We hypothesized that cord blood sampling could delay the time to first blood transfusion.
Study design |
In this single-center, assessor blind, randomized controlled trial, we included extremely low birth weight neonates <28 weeks of gestational age at birth. Five milliliter of blood for initial laboratory investigations was collected either from the placental end of the umbilical cord (study group) or from the neonate upon neonatal intensive care unit admission (control group). Both groups received similar anemia prevention strategies. The primary outcome was the time (in days) to the first packed red blood cell transfusion, and was compared using survival analysis.
Results |
Eighty neonates were enrolled. The time to first transfusion was significantly delayed in the cord sampling group (30 vs 14 days, hazard ratio: 0.44, [95% CI 0.27-0.72], P < .001). Fewer neonates in the cord sampling group were transfused in the first 28 days of life (30% vs 75%, P < .001). Overall transfusion requirements and other clinical outcomes were similar in the groups.
Conclusions |
Initial blood sampling from placental end of umbilical cord, when combined with anemia prevention strategies, significantly prolonged the time to first transfusion and reduced the need for early transfusions among extremely premature neonates.
