The rate of lower reproductive tract infection of pregnant and its effect on pregnancy outcome

Abstract

Objective To investigate the rate of lower reproductive tract infection during pregnancy and the its impact on pregnancy outcome.Methods Five hundred and twenty pregnant women were enrolled in the study who were hospitalized for delivery from Jan.2010 to Jan.2012 at Hebei Port Group Company Limited Harbor hospital.All pregnant women were performed the bacteria detection in vagina before delivery,including candida albicans,bacterial vaginosis,trichomonas,mycoplasma,trachomatis and Neisseria gonorrhoeae,group B hemolytic streptococci GBS.The pregnant outcomes were followed.According to the results of bacteria detection,107 patients (20.58％) were with varying degrees of vaginitis and they were served as positive group.Other 403 patients were served as negative group.Results (1) Of 107 vaginitis women,48 cases (44.86％) were infected with candida albicans,and 22 cases (20.56％) were with bacterial vaginosis.The infection by mycoplasma,chlamydia,group B streptococcal infections were majority,while the trichomonas vaginalis,Neisseria gonorrhoeae infection were minority.(2) Compared with the negative group,incidence of premature rupture of membranes,preterm birth,puerperal infection and fetal distress in positive group were higher and the differences were significant(15.89％ vs.5.08％,12.15％ vs.3.15％,8.41％ vs.1.94％,5.61％ vs.1.21％ ; x2 =14.642,14.498,11.264,7.934; P ＜ 0.01).Conclusion The incidence of genital tract infection is higher during the pregnancy.Bacteria infection detection should be performed and treated as early as possible in order to reduce the occurrence of adverse pregnancy outcome.
