Comparison of Effect of Intrathecal Sufentanil-Bupivacaine and Fentanyl-Bupivacaine Combination on Postoperative Analgesia

Fifty ASA grade I/II patients scheduled for elective lower abdominal, lower limb and urological procedures were divided into two groups of 25 each .The first group (Group S) received 2.5 ml of heavy bupivacaine with 0.2. ml sufentanil made up to 3 ml with saline. The second group (Group F) received 2.5 ml of heavy bupivacaine with 0.5 ml of fentanyl. From our study it can be concluded that bupivacaine sufentanil combination although had shorter onset of action, but had more side effects especially nausea, vomiting and headache. The time for rescue analgesia in both groups was however similar.
