- ABSTRACT: Objective: This prospective randomized study aimed to evaluate the effect of IV lidocaine infusion or gabapentin and their combination in providing efficient analgesia after thyroid surgery. Methods: Eighty-eight patients scheduled for thyroidectomy were randomized into four equal groups (n = 22). Group P (placebo) patients received placebo capsules 1 h preoperatively and intravenous (IV) saline infusion. Group L (Lidocaine): patients received placebo capsules 1 h preoperatively and IV bolus lidocaine 1.0 mg/kg followed by infusion 2 mg/kg/h. Group G (Gabapentin) patients received 600 mg gabapentin capsules 1 h preoperatively and IV saline infusion. Group LG (Lidocaine-Gabapentin) patients received 600 mg gabapentin capsules 1 h preoperatively and IV bolus of 1.0 mg/kg lidocaine followed by infusion 2 mg/kg/h. (lidocaine or saline infusion started before induction of anesthesia and continued until the end of surgery). Intraoperative fentanyl consumption and hemodynamic changes were recorded. Postoperative total tramadol consumption, time to first analgesic request, visual analog scale (VAS) of pain, sedation level, and side effects were assessed for 24 hours. Results: (LG) group had significant lower intraoperative fentanyl and lower postoperative tramadol consumption (p < 0.001) compared to (P), (L) and (G) groups, with prolonged time of first analgesic request (p < 0.001) compared to (P) and (L) groups, and lower VAS compared to other groups (p < 0.001 or p < 0.01). There was significantly lower postoperative nausea and vomiting (PONV) in G & LG groups compared to (P) group (p < 0.01). Conclusion: The combination of preoperative gabapentin and intraoperative lidocaine infusion provided more analgesic effect than either drug alone with lower and more delayed postoperative analgesic requirements and lower VAS. (PONV) was lower in groups received gabapentin.
