Abstract;We investigated the clinical effects of late cord-clamping to prevent anemia and avoid transfusions for very low birthweight infants born under 29 weeks gestation. Hemoglobin, hematocrit, and mean arterial blood pressure just after delivery were significatly higher in the late cord-clamping group. The transfusion tate was significantly lower in the late clamping group (38%) than in the non-late clamping group (68%). There were also significant differences between the two groups in accumulation transfusion avoidance curve by the Kaplan-Meier method. Late cord-clamping was effective especially in infants born at 26-28 weeks gestation, and almost all infants born over 27 weeks gestation did not need a transfusion when late cord-clamping was performed, while most infants born at 23-25 weeks gestation needed transfusions even when late cord-clamping was performed. In multivariate analysis, body weight less than 1,000g, necrotizing enteritis, intraventricular hemorrhage, non-late clamping, and an Apgar score (5min.) of less than 6 were independent risk factors for transfusions.
