Efficacy of Pregabalin as preemptive analgesic in laparoscopic cholecystectomy

Abstract

Introduction: Different pharmacological approach for preemptive analgesia have been tried with varying degree of success. Preemptive analgesia results in decrease in postoperative opioid requirement and hence decreases opioid related complication. Objectives: This study aims to evaluate pregabalin as preemptive analgesic in scheduled cases. Methodology: Fourty ASA I and II  patients posted for elective laparoscopic cholecystectomy under general anesthesia were divided into two groups of twenty. Group A received pregabalin 300 mg, two hours before induction of anesthesia but group B were not given any medication. Postoperative VAS Score, Ramsay Sedation Score, postoperative nausea and vomiting and postoperative opioid requirement in two groups were observed over 48 hours and noted.Results: The mean VAS scores were  higher in control group whereas the mean Ramsay score was higher in group pregabalin in the first six hours in the post operative period which was statistically significant. The mean Ramsay sedation score was same (2) in both the group after twelve post operative period. Postoperative nausea and vomiting was lower in the pregabalin group. Requirement of post operative analgesia was higher in the control group. Conclusion: Preemptive use of Pregabalindecreasespostoperateive pain, postoperative opioid requirement and increases postoperative sedation.
