BackgroundEpisiotomy is a deliberate surgical incision of the perineum with the aim of increasing the vulval outlet to facilitate childbirth. However, it could be associated with some complications, such as pain, hemorrhage, and wound infection. It is a surgical procedure that requires adherence to basic surgical principles of providing adequate analgesia.AimTo determine the efficacy of magnesium sulphate (MgSO4) as an adjunct to local anesthetics for analgesia during episiotomy repair among women that had vaginal delivery at Usmanu Danfodiyo University Teaching Hospital Sokoto, Sokoto, Nigeria.Subject And MethodsThis was a single-blind randomized clinical trial. Pregnant women who had episiotomy during the study period were randomized into two groups. Those in Group A had xylocaine administered alone, whereas those in Group B had xylocaine + MgSO4 administered for repair of episiotomy. Pain was assessed by numeric rating scale at commencement of the repair, at 2 and 6 h after the repair. Patient's level of satisfaction, request for additional analgesia, and side effects were also assessed.ResultsThe pain score in the xylocaine + MgSO4 group was lower throughout the period of assessment. There was no significant difference in the pain scores between the two groups at 0 and 6 h. However, there was significant difference in the mean pain scores between the two groups at 2 h (P < 0.001). There was no significant difference in the level of satisfaction, request for additional analgesia, and side effects between the two groups.ConclusionBoth xylocaine alone and xylocaine with MgSO4 provide adequate perineal pain relief during episiotomy repair. MgSO4 improves the analgesic effect of xylocaine at 2 h after episiotomy repair without any significant side effect.
