The impact of umbilical cord ligation at different times on the premature infants de-livered transvaginally in plateau areas
Objective To compare the impact of different times of umbilical cord ligation on the short-term prognosis of premature in-fants in plateau areas,and to provide reference for determining the optimal time of umbilical cord ligation for premature infants in plateau areas.Methods A total of 100 premature infants delivered transvaginally in plateau areas were randomly divided into 25 ca-ses each in the routine group,60 s group,120 s group and 180 s group,and the umbilical cords were ligated at 30 s,60 s,120 s and 180 s after the deliveries of premature infants,respectively.The incidence of hemoglobin,hematocrit,serum bilirubin and re-lated complications of the premature infants in the four groups were compared at 5-7 days after the birth.Results There was no sta-tistical significance in the incidence of hematocrit,feeding intolerance,hyperbilirubinemia and polycytosis among the four groups(all P＞0.05).The hemoglobin of the routine group was significantly lower than that of the other three groups,and the transcuta-neous bilirubin in the 180 s group was significantly higher than that of the other three groups(both P＜0.05),and there was a statistically significant difference in the incidence of anemia among the four groups(P＜0.05).Conclusion Delayed umbilical cord ligation of premature infants in plateau areas to 60 s-120 s can improve hemoglobin and reduce the incidence of anemia at 5-7 days after the birth,and furthermore,it does not increase the incidence of complications such as polycythemia and hyperbilirubinemia.
