A comparative study between butorphanol and tramadol as adjuvant with epidural bupivacaine for post-operative analgesia after pelvi-acetabular surgery

Epidural analgesia using local anaesthetic agent is popular simple, effective & economical way of providing postoperative analgesia. In few previous study opioids were added with anaesthetics, so that even small doses can provide profound longer duration less side effects. We compared the efficacy epidural butophanol tramadol as adjuvant bupivacaine, for in view safety profile among opioids. Sixty patients undergoing pelvi-acetabular surgery randomly assigned into two groups B T double blinded fashion. Group received 2ml Butorphanol (2mg) group tramadol(100mg) 8ml Bupivacaine (0.125%) first does. 1ml (1mg) 1 ml Tramadol(50mg) 9ml subsequent does when VAS>4. Quality assessed VAS 24hours. Duration calculated by time request. Post-operative nausea vomiting sedation compared. Both butorphanol adequate but significantly lesser requirement analgesic was observed to B. about 6-7 hour 8-9 hours. More PONV more seen. Therefore, it suggests bupivacaine has better quality comparison tramadol. Although causes significant vomiting.
