The objective of this study was to compare continuous versus interrupted sutures for repair of episiotomy following childbirth, regarding the incidence of pain and wound infection. This randomized double blind clinical trial was carried out at Hajar hospital of Shahrecord between September 2008 and July 2009. A total of 148 (74 in each group) healthy women who had undergone vaginal deliveries with episiotomies were allocated to undergone episiotomy using continuous or interrupted suture techniques. In the first group, the incision was repaired with continuous, nonlocking sutures involving the vagina, perineal muscles, subcutaneous, and skin tissues. In the other group the incision was repaired with continuous, locking sutures of the vagina and subcutaneous, interrupted sutures in the perineal muscles and skin. Frequency and degree of pain were evaluated by visual analog scale at 2 hours postpartum and10th and 40th postpartum days. Wound infection was evaluated by edema, ecchymosis, hyperemia, secretion, dehiscence, and fibrosis at 10th days after birth.
