    Abstract:
    STUDY OBJECTIVE: To compare the continuous knotless technique of perineal repair with the interrupted method after spontaneous vaginal birth DESIGN: A randomized controlled trial. DESIGN CLASSIFICATION: Canadian Task Force Classification I. SETTING: This study was undertaken in a university hospital with more than 2200 deliveries per year. The static population of this district includes a wide range of socioeconomic classes and is predominately white. PATIENTS: From May 1 to November 19, 2003, 214 primiparous women with a second-degree perineal tear or episiotomy were randomly allocated to either the continuous knotless technique (CKT; n=107) or the interrupted technique (IT; n=107) suturing method. INTERVENTIONS: The interrupted technique (IT) involves placing 3 layers of sutures whereas the continuous knotless technique (CKT) involves reapproximating vaginal trauma, perineal muscles, and skin with a loose, continuous, nonlocking technique. MEASUREMENTS AND MAIN RESULTS: The primary outcomes of the study were perineal pain (evaluated by visual analogue scale) at 48 hours and day 10 and dyspareunia 3 months after delivery. Secondary outcomes included suture removal, wound dehiscence, analgesia use up to 48 hours, and satisfaction with repair established at 3 and 12 months after childbirth. At day 10, 19 women had dropped out of the study. Significantly fewer women reported pain at 10 days with the CKT than with the IT (32.3% vs 60.4%; p<.001). Analgesia use up to 48 hours postpartum was less in the CKT group than in the IT group (33.6% vs 54.2%; p<.05). No difference was found in superficial dyspareunia at 3 months for the CKT versus the IT group. CONCLUSION: The use of a continuous knotless technique for perineal repair is associated with less short-term pain than techniques with interrupted sutures.
