Preemptive Analgesic Effect of Ketamine in Patients Undergoing Elective Cesarean Section

Abstract

Intraoperative low-dose ketamine had no effect on morphine consumption during 2 to 24 hours after surgery. No significant differences were seen in the pain scores of the 2 groups during the study period. The preoperative administration of 0.5 mg/kg ketamine in patients undergoing cesarean section did not elicit a preemptive analgesic effect.
