INTRODUCTION
Prelabour rupture of membranes is a common obstetrics problem associated with maternal and perinatal morbidity and mortality. The exact cause is not known although various factors are found to be related to this condition. Hence, the objective of this study was to find out the prevalence of prelabour rupture of membranes among pregnant women in a tertiary care centre.
METHODS
This was a descriptive cross-sectional study conducted from 1 November 2021 to 30 November 2022. Ethical approval was taken from the Institutional Review Committee (Reference number: 2078/79/49). A structured proforma was filled out after taking a detailed history from each pregnant woman. Convenience sampling method was used. Point estimate and 99% Confidence Interval were calculated.
RESULTS
Among 700 pregnant women, the prevalence of prelabour rupture of membranes was 56 (8%) (5.36-10.64, 99% Confidence Interval). Among them, 40 (71.43%) occurred in the term, while preterm (before 37 weeks) occurred in 16 (28.57%) of all pregnancies. Previous miscarriage occurred in 15 (26.78%) followed by gestational diabetes mellitus 8 (14.28%).
CONCLUSIONS
The prevalence of prelabour rupture of membranes was found to be lower than other studies done in similar settings.

引言
胎膜早破是一种常见的产科问题，与产妇和围生儿发病率和死亡率有关。虽然发现了各种与这种情况相关的因素，但确切的原因尚不清楚。因此，本研究的目的是确定在一家三级保健中心孕妇中胎膜早破的发生率。
方法
这是一项描述性的横断面研究，于 2021 年 11 月 1 日至 2022 年 11 月 30 日进行。本研究已获得机构审查委员会的伦理批准（编号：2078/79/49）。在对每位孕妇进行详细病史询问后，填写一份结构化的表格。采用便利抽样法。计算点估计值和 99%置信区间。
结果
在 700 名孕妇中，胎膜早破的发生率为 56 例（8%）（5.36-10.64，99%置信区间）。其中，40 例（71.43%）发生在足月时，而早产（37 周前）在所有妊娠中占 16 例（28.57%）。15 例（26.78%）发生过流产，其次是妊娠期糖尿病 8 例（14.28%）。
结论
胎膜早破的发生率低于其他在类似环境中进行的研究。
