Comparison of Epidural Butorphanol and Fentanyl as Adjuvants in the Lower Abdominal Surgery

Background In recent time it is very popular technique to use epidural opioids in management of acute post-operative pain. Aim 1. To assess& compare the onset& duration of sensory block 2. To assess& compare the onset& duration of motor block 3. To assess& compare duration of post-operative analgesia. Material and methods A Prospective Randomized control double blind study of 75 adult patients of either sex with ASA 1& 2 aged 20 - 60 years under going lower abdominal surgery under epidural anesthesia were enrolled in this study. Result Onset and completion of sensory analgesia was earliest in Bupivacaine-Fentanyl (BF) group followed by Bupivacaine-Butorphanol (BB) group and Bupivacaine (B) group, duration of analgesia were prolonged significantly in BB group followed by BF group as compared with B group. Conclusion Addition of a single bolus dose of Butorphanol and Fentanyl along with Bupivacaine given at the start of epidural anesthesia provides good intraoperative and post-operative analgesia& Butorphanol is an attractive alternative as an adjuvant to bupivacaine as it has excellent sedation in postoperative period& longer duration of analgesia.
