目的对Rh(D)阴性血型孕产妇妊娠结局进行分析,探讨Rh(D)阴性血型对妊娠结局的影响。方法产前常规进行Rh血型检测,观察其平均分娩孕周、剖宫产率、顺产率、阴道助产率、胎儿窘迫发生率、新生儿高胆红素血症发生率及新生儿溶血发生率。结果 31例Rh(D)阴性血型产妇平均孕周为38+6周。31例新生儿出生后常规经皮测胆红素,筛查出高胆红素血症高危儿4人,占12.9%。本研究所统计的31例孕产妇中有既往孕产史者为23例,其中孕7月以上孕产史者11例。2例新生儿发生Rh溶血。结论既往有妊娠史甚至有晚期妊娠史的Rh(D)阴性孕妇,其新生儿并非全部发生Rh溶血。加强Rh阴性血型孕产妇监护,以改善妊娠结局及新生儿预后。
Objective To analyze the pregnant outcome of Rh (D) -negative blood type pregnant women and explore the influence of Rh (D) -negative blood type on pregnancy outcome. Methods Rh blood group was routinely tested in prenatal period. The average gestational age, cesarean section rate, cesarean section rate, vaginal delivery rate, fetal distress rate, incidence of neonatal hyperbilirubinemia and neonatal hemolysis were observed. . Results The average gestational age of 31 pregnant women with Rh (D) negative blood group was 38 + 6 weeks. Thirty-one newborns were routinely percutaneously tested for bilirubin, and 4 were high-risk children with hyperbilirubinemia (12.9%). Statistics of the Institute of 31 cases of pregnant women in the history of previous pregnancy were 23 cases, of which more than 7 months of pregnancy in pregnancy in 11 cases. Two cases of Rh hemolysis occurred in newborns. Conclusion Rh (D) -negative pregnant women, who had a history of pregnancy or even a late pregnancy, did not have all Rh hemolysis in their newborns. Strengthen Rh-negative blood group maternal care to improve pregnancy outcome and neonatal prognosis.
