脐带挤压对早产儿血红蛋白量、胆红素及心功能的早期影响
Early effects of umbilical cord milking on hemoglobin, bilirubin and cardiac function in premature infants
【摘要】 目的·探讨脐带挤压对早产儿的血红蛋白量、胆红素及心功能的早期影响,以及对预防贫血的意义。方法·选择2017年7月—11月在上海市嘉定区妇幼保健院出生的孕周<37周的早产儿,按随机原则分为脐带挤压组(n=41)与正常断脐组(n=37)。比较2组早产儿经皮血氧饱和度、不同时间段血红蛋白值、生后72 h内左心功能指标、头颅超声、经皮胆红素水平、光疗总时间等。结果·脐带挤压组入院血红蛋白质量浓度较正常断脐组明显升高,差异有统计学意义(P=0.008);生后3~5 d、8~11 d、14~18 d脐带挤压组血红蛋白质量浓度均明显高于正常断脐组(P<0.05);随访至出生后4个月时,脐带挤压组血红蛋白质量浓度仍高于正常断脐组,但差异无统计学意义(P=0.075)。2组早产儿光疗总时间比较,差异无统计学意义(P=0.849)。2组早产儿在生后72 h左心室射血分数及左心室短轴缩短分数比较,差异均无统计学意义(P>0.05)。结论·脐带挤压可提高早产儿生后早期体内血红蛋白水平,可降低出院时贫血的发生率,且未加重其左心负担,也未升高需要光疗的高胆红素血症的发病率,对于早产儿是一项简单、安全而又能有效提升其血红蛋白浓度的方法。
【Abstract】 Objective · To investigate the impact of umbilical cord milking on hemoglobin, bilirubin and cardiac function in premature newborns, and the signifi cance of prevention of anemia. Methods · A randomized controlled trial was performed in Maternal and Child Health Hospital of Shanghai Jiading from July to November 2017 on neonates born<37 weeks. Preterm newborns were randomly assigned to umbilical cord compression group(experiment group, n=41) and control group(cord clamping within 15 s without compression, n=37). Clinical measures of the outcomes were measured by transcutaneous oxygen saturation(TcSO2), hemoglobin at different periods, left heart function within 72 h, cranial ultrasound, transcutaneous bilirubin,the total time of phototherapy. Results · Hemoglobin values were signifi cantly higher in the experiment group than those in the control group in vein at the fi rst time(P=0.008). Hemoglobin values were signifi cantly higher in the experiment group than those in the control group 3-5 d, 8-11 d, and14-18 d after birth(P<0.05). Four months after birth, hemoglobin in the experiment group was higher than that in the control group, but there was no signifi cant difference(P=0.075). There was no signifi cant difference in the total time of phototherapy between the two groups(P=0.849). There were no signifi cant differences between the two groups on left ventricular ejection fraction and left ventricular short axis shortening score 72 h after birth(P>0.05).Conclusion · Umbilical cord milking can increase the hemoglobin level to premature infants and reduce the incidence of anemia at discharge, and it does not increase the risk of cardiac insuffi ciency and hyperbilirubinemia. This practice has been shown to be simple and safe.
