A Comparative Study of 0.5% Bupivacaine (Hyperbaric) and 0.5% Bupivacaine (Hyperbaric) with Dexmedetomidine for Spinal Anesthesia in Lower Abdominal Surgeries

Spinal anesthesia is preferred choice of anesthesia in lower abdominal surgeries since long time. However, problem with this is limited duration of action, so for long duration surgeries alternative are required. Dexmedetomidine is a highly selective alpha-2adrenergic agonist has property to potentiate the action of local anesthetic used in spinal anesthesia. To evaluate the effects of intrathecal dexmedetomidine on spinal anesthesia with respect to:-Onset and duration of sensory blockade, Onset and duration of motor blockade, Time of two segment regression, Duration of analgesia, Haemodynamic stability, Side effects / complications.
