In this prospective randomized trial, investigators compared the analgesic effect of subanesthetic dose of ketamine versus placebo in parturients undergoing cesarean section under spinal anesthesia.~The patients were randomized in two groups:~Group Ketamine: these patients recieved 0.25 mg/kg of Ketamin intravenously 5 minutes after the spinal anesthesia.~Group Placebo: recieved 20 ml of normal saline solution intravenously 5 minutes after the spinal puncture.~The investigators recorded intra demographic, intraoperative and post operative data.~The main outcome was the analgesic score: the visual analog scale (VAS). dynamic VAS was also monitored at 24 hours post operatively.
