【摘要】：目的:探讨不同断脐时间对阴道分娩早产儿的影响。方法:选择120例经阴道分娩的早产儿及产妇作为研究对象。将120例产妇按照随机数字表法分为A、B、C、D组,各30例。A组:产后10 s内立即断脐;B组:产后30 s断脐;C组:产后60 s断脐;D组:产后90 s断脐。收集各组产妇、新生儿基本资料,记录各组新生儿血红蛋白(Hb)和红细胞压积(HCT)值、贫血发生率、输血率、经皮胆红素高峰值、光疗时间、高胆红素血症发生率、颅内出血发生率。结果:B、C、D组早产儿生后24 h Hb和HCT值均高于A组(P0.01),B、C、D组比较差异无统计学意义(P0.05)。B、C、D组早产儿出生后1周Hb和HCT值均高于A组(P0.01),且D组高于B、C组(P0.01),B组与C组之间差异无统计学意义(P0.05)。B、C、D组早产儿贫血率、输血率均低于A组(P0.05),B、C、D组之间差异均无统计学意义(P0.05)。4组早产儿之间经皮胆红素高峰值、光疗时间、高胆红素血症发生率、颅内出血发生率差异均无统计学意义(P0.05)。结论:对经阴道分娩的早产儿延迟断脐30~90 s,可以改善新生儿血供,降低贫血发生率和输血率,且并不增加胆红素升高风险和光疗的风险。如果条件允许,延迟结扎脐带90 s能更好地改善早产儿预后。
[Abstract]:Objective: To investigate the effect of different umbilical time on preterm infants of vaginal delivery. Methods: 120 preterm and parturient women who were given vaginal delivery were selected as the research subjects. 120 cases were divided into A, B, C, D, 30.A groups, each of which were immediately broken umbilical cord within 10 s postpartum; B group: 30 s broken umbilical cord after postpartum; group C: 60 s broken umbilical after postpartum; D group: postpartum 90 s break. The basic data of all groups of mothers and neonates were collected, the values of hemoglobin (Hb) and hematocrit (HCT), the incidence of anemia, the rate of blood transfusion, the high peak value of transdermal bilirubin, the time of phototherapy, the incidence of hyperbilirubinemia, and the incidence of intracranial hemorrhage were recorded. Results: the 24 h Hb and HCT of the premature infants in the group of B, C and D were all higher than those of the A group (P0.01), B, C, and HCT There was no statistical significance (P0.05) (P0.05).B, C, and D in group D were higher than that in group A (P0.01), and D group was higher than B, C group (P0.01). There was no significant difference between the high peak value of the transdermal bilirubin, the time of phototherapy, the incidence of hyperbilirubinemia and the incidence of intracranial hemorrhage (P0.05). Conclusion: delayed umbilical cord 30~90 s in preterm neonates with vaginal delivery could improve the blood supply of the newborn, reduce the incidence of anemia and the rate of blood transfusion, and did not increase the risk of bilirubin elevation and phototherapy. If conditions permit, delayed ligation of umbilical cord 90 s can better improve the prognosis of premature infants.
