DEXMEDETOMIDINE AS AN ADJUNCT TO SPINAL ANESTHESIA IN INTRATHECAL VERSUS INTRAVENOUS DEXMEDETOMIDINE LOWER LIMB ORTHOPEDIC SURGERIES

Purpose of the study was to compare about beginning and time period of sensory and motor block, hemodynamic security, duration of analgesia and symptoms between two groups. This study was performed in 60 American Society of Anesthesiologists I / II patients undergoing orthopaedic surgery in the lower limb at Krishna Hospital, Karad. Patients were randomly assigned to the IT and IV groups. Before Subarachnoid block (SAB) in IV group dexmedetomidine was given bolus 1 µg/kg over 10 min and then after SAB 0.5 µg/kg/hr throughout surgery. In IT group equal volumes of normal saline were infused before and after SAB. In IT group with 3ml bupivacaine 5 µg dexmedetomidine was added intrathecally. While in IV group equal volume of normal saline was added in SAB.
