Abstract

Introduction: umbilical cord blood is useful for certain transplants. Different factors will determine the volume of blood obtained, such as the time of cord clamping. Early clamping is conducted before the first minute of life; among its effects, newborns will present lower levels of haemoglobin, but will require less phototherapy. Delayed clamping is conducted after the first minute of life, increasing the volume of blood transfused to the newborn: hematocrit, haemoglobin and ferritin; but it can cause polycythemia. There is no evidence recommending the required time of clamping for blood collection for donation that will be compatible with collecting a sufficient volume of blood.
Objective: to compare if enough sample for donation is obtained both with delayed and early clamping.
Material and methods: cohort study; one of the arms defined by women who have undergone an early umbilical cord clamping, and the other by those who have undergone delayed clamping. Other variables were also studied, such as gestational age, placenta weight, gender, and percentile and weight of the newborn.
Results: in total, 38.8% valid samples were obtained: 22.4% suitable samples with delayed clamping vs. 59.6% suitable samples with delayed clamping.
Discussion and conclusions: there is a higher (70%) benefit for newborns with a higher number of valid donations (≥ 90 g) through clamping at 30-60 seconds.
