孕晚期B族链球菌感染孕妇母婴不良结局发生情况

The situation of adverse maternal and infant outcomes of pregnant women with group B streptococcal infection during the third trimester of pregnancy

目的:分析产前B族链球菌(GBS)感染后母婴不良结局发生情况。方法:选取2019年6月-2020年9月本院产前孕晚期(孕35~37周)阴道分泌物GBS检测阳性的孕妇80例作为观察组,阴性孕妇80例作为对照组,追踪母婴结局。结果:观察组胎膜早破(55.0%)及总不良妊娠率(72.5%)均高于对照组(35.0%、45.0%),新生儿窒息(8.8%)及总不良情况(20.0%)均高于对照组(0、2.5%)(均P<0.05)。结论:孕妇产前GBS感染可增加不良妊娠发生,导致新生儿不良结局增加。因此,应加强孕晚期GBS检测,及时干预,降低不良妊娠发生。

Objective:To study the situation of adverse maternal and infant outcomes of pregnant women with group B streptococcal(GBS)infection during the third trimester of pregnancy.Methods:80 pregnant women with positive GBS in vaginal secretion during the third trimester of pregnancy(35-37 gestational weeks)were selected in observation group and 80 pregnant women with negative GBS in vaginal secretion were selected in control group from June 2019 to September 2020.The maternal and infant outcomes in the two groups were followed up.Results:The rates of the premature rupture of membranes(55.0%)and the total adverse pregnancy(72.5%)of the women in the observation group were significantly higher than those(35.0%and 45.0%)of the women in the control group,and the rates of the neonatal asphyxia(8.8%)and the total adverse events(20.0%)in the observation group were also significantly higher than those(0 and 2.5%)in the control group(all P<0.05).Conclusion:The pregnant women with prenatal GBS infection can increase the incidence of their adverse pregnancy,leading to the increase of neonatal adverse outcomes.Therefore,it is necessary to strengthen the detection of GBS infection of the pregnant women during the third trimester of pregnancy,and to intervene timely for reducing the incidence of adverse pregnancy.
