Abstract

The aim of the study is to study Effects of dexmedetomidine as an adjuvant to levobupivacaine in patients undergoing lower limb surgeries under subarachnoid block. A full assessment of history, clinical examination, and revision of investigations was conducted preoperatively for all patients. Baseline vitals, Sensory and Motor block with analgesi a requirement were recorded. All patients were kept nil per oral overnight. Patients were preloaded with Ringer’s lactate solution 15 ml/kg. Results: Mean duration of sensory block in group Levobipivacaine was 112.28 min and in group Dexmedetomidine with levobupivacaine was 204.74 min. Prolong duration occur in the dexmedetomiine with levobupivacaine group. In the present study there was a significant difference in duration of motor block across the two groups. In group Levobipivacaine mean duration of motor block was 156.51 min, and in group Dexmedetomidine with levobupivacaine was 249.77 min. Conclusion: Dexmedetomidine may be used as an adjuvant to intrathecal hyperbaric Levobupivacaine in elective lower limb orthopaedic surgery to prolong the duration of motor and sensory block when compare to use hyperbaric Levobupivacaine alone.
