Background and Objectives: Using opioid alone for postoperative pain relief is usually inadequate, and higher doses can cause a multitude of complications. A drug, which has anxiolytic property without the adverse effects of traditional analgesics mentioned, may be an attractive choice for postoperative analgesia. This study was done to compare analgesic efficacy of different nonopioid drugs on early postoperative pain and thus opioid-sparing effect. Materials and Methods: It was a randomized controlled trial. Sixty patients scheduled to undergo elective abdominal surgery under general anesthesia were assessed in the study. Primary Objective: The primary objective of this study was to observe the effect of preemptive pregabalin and pregabalin with intravenous (IV) ketamine on Cumulative analgesic requirement postoperatively. Secondary Objective: The secondary objective of this study was to observe the effect of preemptive pregabalin and pregabalin with IV ketamine on (1) analgesia and (2) adverse effects. Patients were randomly divided into two groups each containing 30 patients. Group P received 150 mg of oral pregabalin, 2 h before induction of anesthesia. Group PK received 150 mg of oral pregabalin, 2 h before induction of anesthesia, and injection ketamine 0.15 mg/kg intravenously just before induction of anesthesia. Heart rate and mean blood pressure (MBP) were observed and recorded at different time intervals during surgery. Heart rate, MBP, time to first analgesic demand, visual analog scale (VAS) score, total postoperative analgesic requirement, sedation score, and side effects were recorded in postoperative period. Results: In Group P, the mean total analgesia requirement in postoperative period was 44.47 ± 5.06 mg, whereas in Group PK, it was 41.8 ± 2.34 mg (P = 0.006). VAS score and time to first analgesic demand were insignificantly higher in Group P. No statistically significant difference was found in side effect profile among the two groups. Conclusion: From our study, it could be concluded that a combination of oral pregabalin and IV ketamine when administered preoperatively can decrease opioid consumption while providing good pain control.
