Abstract :

BACKGROUND: A clinical study was undertaken in 100 patients belonging to ASA 1 and 2 scheduled for lower abdominal and lower limb surgeries with 0.5% Bupivacaine and 0.5% Bupivacaine with Ketamine 50mg to compare sensory and motor block in view of onset, level, degree, duration and hemodynamic changes. METHODOLOGY: They are allocated randomly into two groups; Group B and Group BK, 50 members each to compare the effectiveness of 0.5% Bupivacaine and 0.5% Bupivacaine with 50mg Ketamine. In Group B 50 patients received intrathecal 0.5% Bupivacaine 2.5ml(12.5 mg) with 1.0ml normal saline, total volume of 3.5ml. In Group BK, 50 patients received intrathecal 0.5% Bupivacaine 2.5ml (12.5 mg) with 50mg Ketamine (total volume of 3.5ml) RESULT: The onset of sensory blockade was faster in Group BK than compared to Group B. Duration of sensory block and analgesia was significantly prolonged in Group BK. Haemodynamic parameters were comparatively more stable in Group BK. CONCLUSION: Ketamine 50mg with 12.5mg H.Bupivacaine when given intrathecally hastened sensory onset, prolonged the sensory block and improve the quality of analgesia in the early postoperative period
