This double blind randomized clinical trial was conducted to evaluate the pre-emptive use of gabapentin 900 mg and pregabalin 300 mg in reducing postoperative pain. Methods: A total number of 75 patients undergoing lower gynecological procedures were prospectively randomized, into three groups (group A, B and C), each group including 25 patients with total 75 patients. Pregabalin, gabapentin or placebo, the pain was assessed on a visual analogue scale (VAS) at 0, 6, 12, 18 & 24 hours postoperatively. Duration of effective analgesia was documented, and administration of extra analgesic doses of meperedine required in the first 24 hours. Results: Patients in the gabapentin or pregabalin had significantly lower VAS scores at 6, 12, 18 and 24 hours, than those in the placebo group. As for rescue analgesia with mepredine consumed in the gabapentin, and pregabalin were significantly less than in the placebo. As for the complications, both drugs had increased incidence of nausea, vomiting and dizziness postoperatively, while no significance was found between all groups as regard hypotension, bradycardia and shivering. Conclusion: Preoperative use of pregabalin or gabapentin provides comparable but significant prolonged postoperative analgesia, less nausea and vomiting compared to placebo after gynecological surgeries. However, it was associated with increased incidence of postoperative dizziness.展开更多
