Epidural Nalbuphine Versus Dexmedetomidine as Adjuvants to Bupivacaine in Lower Limb Surgeries

"Surgery will be started under spinal anesthesia. When sensory block regress to T12 dermatome Epidural bolus dose will be given epidural bolus dose of 12ml (10ml 0.25% bupivacaine + 2ml normal saline) The onset of sensory blockade injected epiduraly with maximal cephalic spread will be assessed by bilateral pinprick method along the midclavicular line, every 5 min for 30 min and then every 30 min.~top up dose of 8ml will be given postoperative (6ml 0.25% bupivacaine + 2ml normal saline)."
