Vaginal Microflora in High Vaginal Swab in Prelabour Rupture of Membrane: A Descriptive Cross-sectional Study.

Abstract

Introduction: Premature rupture of membrane (PROM) refers to the disruption of the fetal membrane before the beginning of labor, resulting in spontaneous leakage of amniotic fluid. Cervicovaginal infection is an important risk factor of PROM and can lead to complications to mother and the child. This study aimed to delineate the bacterial patterns found in PROM so that the ideal appropriate responsive antibiotics can be chosen.

Methods: A descriptive cross-sectional was done during the period of 6 months from December of 2023 to May 2023, to characterize the microorganisms in the vaginal fluid found in antenatal women presenting with premature rupture of membraneafter obtaining ethical approval (IRC number: 20102023/02). A total of 117 antenatal women diagnosed with premature rupture of membrane were included in the study. High vaginal swabs were collected for microbial culture and sensitivity. Data were entered using Microsoft Excel 2000 (v9.0) and Statistical Package for the Social Sciences (SPSS) software version 26.0 was used for analysis.

Results: Out of 117 samples, culture growth was present in the culture of high vaginal swabs of 23 (19.66%) women. The high vaginal swab cultures from the samples collected in women presenting with PROM reported 9 different types of pathogens E. coli in 12 (52.17%), Klebsiella in 4 (17.39%) and Pseudomonas in 2 (8.70%) cultures.

Conclusions: This study reveals diverse microorganisms in premature rupture of membrane cases, with E. coli being the most common. Identifying these bacterial patterns is essential for selecting effective antibiotics, improving maternal and neonatal outcomes, and reducing morbidity and mortality by early detection and treatment of vaginal infections.
