Factors associated with the performance of episiotomy

ABSTRACT Objective: To analyze the factors associated with the performance of episiotomy. Methods: Cross-sectional study, developed with data from the research “Born in Belo Horizonte: Labor and birth survey, “conducted with 577 women who had their children via vaginal birth. In order to verify the magnitude of the association between episiotomy and its possible determinants, logistic regression models were constructed to estimate the odds ratio. Results: Episiotomy was performed in 26.34% of women, and 59.21% knew they had been subjected to it. We observed that younger women, primiparous women, women assisted by a professional other than the obstetric nurse and women who had their babies in a private hospital have an increased chance of being submitted to this procedure. Conclusion: Considering the rates of episiotomy, this study highlights the need for the absolute contraindication to indiscriminate performing it.

摘要
研究目的：分析与会阴切开术（episiotomy）实施相关的影响因素。
研究方法：本研究为横断面研究，依托《贝洛奥里藏特出生：分娩与生产调查》（Born in Belo Horizonte: Labor and Birth Survey）的研究数据开展，纳入577名经阴道分娩的女性作为研究对象。为验证会阴切开术与其潜在影响因素间的关联强度，本研究构建logistic回归模型以估算比值比。
研究结果：26.34%的女性接受了会阴切开术，其中59.21%知晓自己曾接受该手术。研究发现，年龄较小的初产妇、由非产科护士的专业人员助产的女性，以及在私立医院分娩的女性，接受该手术的概率显著升高。
研究结论：结合本次研究中的会阴切开术实施率，本研究强调亟需严格杜绝无指征地开展会阴切开术。
