COMPARISON OF INTRATHECAL BUPRENORPHINE VERSUS CLONIDINE AS AN ADJUVANT TO 0.5% HYPERBARIC BUPIVACAINE IN LOWER ABDOMINAL SURGERIES
Keywords:Clonidine, Buprenorphine, Intrathecal
Introduction: Present study was undertaken to compare the efficacy of intrathecal clonidine or buprenorphine with bupivacaine in lower abdominal surgeries.
Methods:90 ASA I and II patients undergoing lower abdominal surgeries were randomly allocated into three groups(n=30). Group A received 3ml of 0.5% hyperbaric bupivacaine with 1ml normal saline, GroupB received 3ml of 0.5% hyperbaric bupivacaine with 60 mcg buprenorphine(1:5 dilution) and Group C received 3ml of 0.5% hyperbaric bupivacaine with 30mcg clonidine(1:5 dilution) respectively (Total volume 4ml). Onset time and duration of sensory and motor block, duration of analgesia, hemodynamics, VAS score, sedation score and side effect were compared.
Results: The duration of analgesia was significantly longest in GroupC (354.50±38.48min), followed by Group B (277.10±25.47min) and Group A(131.50±20.15min) (p<0.001)
Conclusion: On comparing the two drugs, Clonidine appears to be superior in terms of postoperative analgesia.
