Abstract :

 Background : The Study has been undertaken to evaluate the efficacy of dexmedetomidine as an intrathecal adjuvant for spinal anaesthesia by observing the onset, duration of motor and sensory blockade, level of sedation, post operative analgesia and stability of cardiovascular and respiratory system with hyperbaric bupivacaine plus dexmedetomidine in subarachnoid block. Method and material :– Patient were randomly assigned in one of the two groups in a double blind fashion. Group I C (Control) Patient receiving .5% hyperbaric bupivacaine + Normal Saline (2+.05ml) Group II D patient receiving .5% hyperbaric Bupivacaine + preservative free Dexmedetomidine 5 g (2+0.05ml). Smaller volume were taken with insulin syringe and total solution is made 2.05ml. Result :– In our study a total of 60 patient were selected, 30 patients in each group randomly assigned in one of two groups. In our study onset of sensory and motor block was earlier with intrathecal dexmedetomidine in comparison to control group. Addition of dexmedetomidine to intrathecal bupivacaine caused prolongation of duration of sensory block, motor block and post operative analgesia. The study showed better block characteristic in bupivacaine + dexmedetomidine group with respect to bupivaicaine + normal saline. Conclusion :–Addition of dexmedetomidine in spinal anaesthesia produces early onset, prolonged duration of sensory and motor blocks and prolonged pain free post operative period without increasing side effects or complications.
