Influence of B group streptococcal infection on pregnancy outcome in pregnant women during 36～38 weeks

目的探究妊娠36~38周孕妇出现B族链球菌感染对于妊娠结局的影响。方法于2015年10月~2016年12月间在我院产科接受B族链球菌感染检测的3000例妊娠36~38周孕妇中将阳性的300例孕妇作为观察组,同时随机选出300例阴性的孕妇作为对照组,对比分析两组孕妇的妊娠结局。结果观察组孕妇的胎膜早破发生率10.7%和产妇感染率11.7%均高于对照组的3.3%、4.0%,P<0.05;在产后出血发生率和羊水污染率上,两组差异无统计学意义,P>0.05;观察组新生儿的肺炎发生率、窒息发生率、呼吸窘迫综合征发生率分别为7.0%、9.0%、6.0%,对照组分别为2.7%、3.3%、2.3%,P<0.05。结论妊娠36~38周孕妇出现GBS感染会对妊娠结局造成一定不良影响,威胁母儿的健康,临床上必须加强对GBS的防治。

Objective To explore the influence of group streptococcal （ GBS ） infection on pregnancy outcome in pregnant women during 36-38 weeks. Methods In the 3000 patients tested for B group streptococcal infection and 36-38 weeks pregnant in department of Obstetrics and Gynecology of our hospital from October 2015 to December 2016, 300 positive pregnant women were selected as observation group, meanwhile, 300 negative pregnant women were selected as control group. The pregnancy outcome of the two groups were compared and analyzed. Results The incidence of prom in the observation group was 10.67% and the rate of maternal infection was 11.67%, which were higher than those in the control group with 3.33% and 4%, P 〈 0.05. In the incidence of postpartum hemorrhage and amniotic fluid contamination rate, the difference between the two groups was not obvious, P 〉 0.05. The incidence of pneumonia, the incidence of asphyxia and respiratory distress syndrome in the observation group were 7%, 9% and 6%, respectively. The control group was 2.67%, 3.33%, 2.33%, P 〈 0.05. Conclusion On 36-38 weeks gestation, GBS infection in pregnant women .will have some adverse effects on pregnancy outcome.
