Epidural pethidine was compared with epidural saline for relief of pain from episiotomy wounds. Pethidine 25 mg administered by the lumbar epidural route produced significant analgesia. However, the incidence and severity of episiotomy pain are so variable that routine use of the technique is not recommended.
