Abstract

Objectives: To determine the incidence of group B streptococcus and related factors in preterm premature rupture of membranes from 22 to 34 gestational weeks at Hanoi Obstetrics and Gynecology Hospital between August 2021 and October 2022. Methods: Our cross-sectional study selected 75 cases with preterm premature rupture of membranes (PPROM). Results: 16 percent of patients with PPROM was positive for GBS. The incidence of GBS patients with premature rupture of membranes in group of lower genital tract infection was 21,4%. Among patients with cultures positive for group B Streptococcus, there was a trend for patients from 28 to 34 gestational weeks compared with those from 22 to 27 gestational weeks (20% vs 5%), but the difference was not statistically significant. The rate of patients who remained undelivered 7 days after admission was 58,3% and ≥ 30 days was 0%. Conclusion: Patients with a history of miscarriage/abortion or genital tract infections had a higher rate of positive for GBS.
