35～37周孕妇B族链球菌带菌情况及孕妇妊娠结局分析

Group B streptococcus germ carrying and pregnancy outcomes of women at 35-37 weeks of pregnancy

目的分析35～37周孕妇GBS带菌情况及其妊娠结局差异。方法选取2018年1月‐2018年7月进入该院体检和生产的产妇162例进行回顾性分析,根据B族链球菌(GBS)检测结果分为带菌组(42例)和正常组(120例)。比较两组产妇分娩方式及妊娠结局差异,比较两组所产新生儿不良事件发生率。结果带菌组孕妇顺产率35.71%明显低于正常组62.50%(P <0.05),产钳助产率16.67%明显高于正常组2.50%(P <0.05);带菌组产妇出现胎膜早破、早产和产褥感染的比例明显高于正常组(P>0.05);带菌组新生儿患肺炎、败血症、窒息及黄疸的发生率高于正常组(P <0.05)。结论35～37周孕妇GBS带菌率为25.93%,带菌孕妇产钳助产比例高,且孕妇及新生儿出现不良妊娠结局的可能性增加。

【Objective】To analyze the differences of group B streptococcus(GBS)germ carrying and pregnancy outcomes in women at 35-37 weeks of pregnancy.【Methods】Totally 162 cases of pregnant women who entered our hospital for physical examinations and productions from January 2018 to July 2018 were retrospectively analyzed.According to the detection results of GBS,they were divided into germ carrying group(42 cases)and normal group(120 cases).The differences in maternal delivery modes and pregnancy outcomes were compared between the two groups.The incidence rates of adverse events in neonates were compared between the two groups.【Results】The spontaneous delivery rate in germ carrying group was significantly lower than that in normal group(35.71%vs.62.50%)(P<0.05),and the forceps delivery rate was significantly higher than that in normal group(16.67%vs.2.50%)(P<0.05).The proportions of premature rupture of membranes and puerperal infection in germ carrying group were significantly higher than those in normal group(P>0.05).The incidence rates of pneumonia,sepsis,asphyxia and jaundice in neonates in germ carrying group were higher than those in normal group(P<0.05).【Conclusions】The rate of GBS germ carrying is 25.93%among women at 35-37 weeks of pregnancy,the proportion of forceps delivery is high in germ carrying pregnant women,and the possibility of adverse pregnancy outcomes increases in these pregnant women and neonates.
