Abstract :

AIM AND OBJECTIVE: Comparative study of 0.5% bupivacaine with dexmedetomidine and 0.5% bupivacaine in subarachnoid block in urological surgeries for perioperative analgesia Ÿ Onset and duration of adequate analgesia Ÿ Onset and duration of motor and sensory block Ÿ Adverse effects, if any METHODOLOGY: 60 patients undergoing lower abdominal urological procedures were randomly allocated to 2 groups of 30 each. Group A 30 patients received 12.5 mg of hyperbaric 0.5% bupivacaine plus 0.5ml normal saline in Sub arachnoid block. Group B 30 patients received 12.5mg of hyperbaric 0.5%bupivacaine with 5 microgram of Dexmedetomidine in Sub arachnoid block. Results: The duration of analgesia, time to reach T10 level block (p=0.006), duration of motor blockade (p=0.0) were prolonged in group B which was statistically significant. Conclusion: Intrathecal addition of dexmedetomidine to bupivacaine is associated with prolonged motor blockade,prolonged sensory blockade,more hemodynamic stability, reduced demand for rescue analgesics in 24 hrs compared to Bupivacaine alone for sub arachnoid block.
