Abstract:
Objective To investigate the effects of different umbilical cord ligation methods on anemia and jaundice in preterm infants with a gestational age less than 32 weeks.Methods A total of 135 preterm infants with a gestational age less than 32 weeks were recruited and randomly divided into the umbilical cord milking group,the delayed cord clamping group and the immediate cord clamping group,with 45 cases in each group.Comparisons among three groups were performed on hemoglobin,hematocrit at 1 h and 1 week after birth,and bilirubin peak,total time of phototherapy,the incidence of anemia,pathologic jaundice as well as polycythemia before discharge.Results Finally 40 cases in the umbilical cord milking group,42 cases in the delayed cord clamping group and 38 cases in the immediate cord clamping group were recruited.Compared with the immediate cord clamping group,Hb(g/L)and hematocrit(％) levels were significantly higher in the umbilical cord milking group and the delayed cord clamping group(P＜0.05),the anemia rate was significantly lower in umbilical cord milking group and the delayed cord clamping group(P＜0.05).However,there were no statistical differences in Hb(g/L) and hematocrit(％) levels as well as ane mia rate between the umbilical cord milking group and the delayed cord clamping group (P＞0.05).There were no significant differences among three groups in bilirubin peak,total time of phototherapy and the incidence of pathologic jaundice as well as polycythemia.Conclusion Umbilical cord milking and delayed cord clamping can both reduce the anemia rate,but not increase the risk of pathological jaundice.Umbilical cord milking can be preferred method for preterm infants with a gestational age less than 32 weeks and asphyxia.
