Abstract:
Objective:To investigatethe maternal and infant adverse outcomes of group B streptococcus (GBS) colonization during the late pregnancy.Methods:A total of 567 pregnant women who underwent obstetrics and gynecology examination in Yuyao People′s Hospital from December 2018 to June 2019 were selected for the study. Internal vaginal secretions of all the pregnant women were extracted from the lower 1/3 of the vagina for bacterial culture, and GBS culture and screening were performed on pregnant women. According to the results of GBS screening, pregnant women were divided into GBS negative group (8 cases) and GBS positive group (559 cases). The general condition and pregnancy outcomes of pregnant women were compared between the two groups, and the correlation between pregnancy outcomes and streptococcus colonization was analyzed.Results:There were no statistically significant differences in age, gestational weeks, number of births, number of pregnancies, history of abortion, residence area and ethnicity between the two groups ( P>0.05). The incidence of premature rupture of membranes and fetal distress in GBS positive group were higher than those in GBS negative group:5/8 vs. 7.69%(43/559), 3/8 vs. 5.01%(28/559), and the differences were statistically significant ( P<0.05). Spearman single factor correlation analysis showed that GBS colonization in pregnant women were positively correlated with premature rupture of membranes and fetal distress ( r = 0.632, 0.573, P<0.05). Conclusions:GBS colonization in late pregnancy is closely related to pregnancy outcomes, and strengthening GBS screening has great significance to reduce adverse pregnancy outcomes.
