Abstract

Spinal anesthesia is most preferred regional anesthesia for lower limb orthopedic procedures. Present study is to assess post-operative analgesia of dexmedetomidine in subarachnoid block for patients undergoing orthopedics lower limb surgeries. Materials and Methods:42 patientsaged 20-65 years selected for lower limb surgeries, belonging to ASA class 1 and 2 were given Subarachnoid block using 0.5% Hyperbaric Bupivacaine 2.5ml with 0.5 ml of 5mcg Dexmedetomidine. Results:Time taken to the onset of sensory block was found to be 2.16±0.37 minutes. Time to onset of motor block was 3.02±0.42 mins. Total duration of motor block was 237.68 ± 11.62 min. The duration of analgesia was 462.08± 18.32 min. No significant variations in the hemodynamic parameters were noted. Conclusion: Dexmedetomidine improves the postoperative analgesia in a dose of 5 mcg and can be safely used inorthopedic lower limb surgeries.
