Spinal subarachnoid block (SAB) is the first choice anesthesia in lower abdominal and lower limb surgeries. It produces a varying degree of sensory analgesia, motor blockade, and sympathetic blockade depending on the dose, concentration, and volume of the local anesthetic given. This study was undertaken to assess the degree of sensory and motor block with 150 μg of oral versus intramuscular clonidine as an adjuvant to bupivacaine for spinal anesthesia.
