Abstract
This study was conducted in 106 adult patients with ASA physical status I-II planed for lower abdominal uro -gynac surgeries under spinal anaesthesia. We compared the onset & duration of motor and sensory block and time to two segment regression from maximal level achieved after giving 2.5ml of 0.75% Ropivacaine + 5µg dexmeditomidine (group-RD) versus 2.5 ml of 0.75% Ropivacaine + 25µg fentanyl intrathecally(group-RF).We observed that onset of sensory and motor blocks were not statistically significant in both groups. Duration of complete motor & sensory blocks were significantly shorter in group-RF as compared to group-RD. Time to 2 segment regression of sensory blockade from maximum level was statistically significant in group-RF compared to RD group. Haemodynamic parameters were comparable in both groups. Demand for rescue analgesia was later and number of doses of rescue analgesia was lesser in group RD Peri-operative and post-operative complications were less & comparable in both groups.To conclude, we found that intrathecal (5µg) DXM supplementation with 0.75% ropivacaine seems to be a better alternative to intrathecal (25µg) fentanyl with 0.75% ropivacaine since it produces prolonged sensory& motor blockade and more effective pain relief, thus making it a more lucrative option for lower abdominal and uro-gynacological surgeries.
