Does episiotomy prevent perineal trauma and pelvic floor relaxation?
OBJECTIVE: To compare the outcomes of the current practice of liberally or routinely employing episiotomy to prevent perineal tears and pelvic floor relaxation (control group) to a policy of restricting episiotomy use to specific fetal and maternal indications (experimental group). DESIGN: A randomized controlled trial (RCT). SETTING: Three university hospitals in Montreal. SUBJECTS: Seven hundred three low-risk women enrolled at 30 to 34 weeks of gestation were randomized late in labor to the designated trial arm, by parity, and followed up to 3 months postpartum. MAIN OUTCOME MEASURES: Antepartum and postpartum information on perineal trauma and pain, pelvic floor symptoms (urinary incontinence), and sexual activity was collected through the use of standard questionnaires; pelvic floor function was measured by electromyographic (EMG) perineometry. RESULTS: Restricting episiotomy use in primiparous women was associated with similar sutured perineal trauma to the liberal or routine app
