Objective: Postoperative nausea and vomiting (PONV) is a common postoperative complication. The aim of this study was to investigate the efficacy of gabapentin and dexamethasone as new treatment strategies in the treatment of PONV. Methods: This retrospective study included a total of 136 ASA I-II patients aged 18-70 years who underwent elective cholecystectomy. Group D (n=66) received 4 mg intravenously dexamethasone after anesthesia induction and Group G (n=70) received 600 mg gabapentin oral treatment. Standard DII and V5 lead ECG, automatic non-invasive blood pressure and peripheral oxygen saturation monitoring was applied to all patients in the general operating room, anesthesia maintenance was provided with total intravenous anesthesia after orotracheal intubation and at the end of surgery, patients were transferred to the postoperative care unit. Nausea and vomiting symptoms, pain scores and the time and dose of additional antiemetic/analgesic requirements in the first 24 hours were monitored. Results: There were no statistically significant demographic differences between the groups and the results showed that both dexamethasone and gabapentin were effective in preventing PONV. The need for rescue antiemetic therapy was similar in both groups (p=0.2). Significantly less postoperative analgesic was required in the gabapentin group than in the dexamethasone group. Conclusion: Antiemetic drug prophylaxis should be administered to patients at high risk of PONV and treatment with different groups of antiemetic drugs should be considered. Dexamethasone and gabapentin can be considered effective drugs for the prevention of PONV.
