Postoperative nausea and vomiting (PONV) is a well-known entity following surgical procedures and may result in serious complications including aspiration of gastric contents, prolonged recovery period, and impaired surgical wound healing. Laparoscopic surgery is a known risk factor for PONV. Also, the incidence of vomiting after ear nose throat (ENT) surgeries is relatively high.

Our aim of the study is to compare the effectiveness of ondansetron, palonosetron, ramosetron, and metoclopramide to prevent PONV in patients undergoing laparoscopic and ENT surgery under general anesthesia.

The present study was conducted on 120 adult patients scheduled for elective laparoscopic chole­cystectomy and ENT surgery under general anesthesia. All patients were randomized into four groups (O, P, R, and M) with 30 patients each and received injection ondansetron (4 mg), palonosetron (0.075 mg), ramosetron (0.3 mg), and metoclopramide (10 mg) intravenously during premedication. Patients were observed intraoperatively and 24 hours postoperatively for any episodes of nausea and vomiting. All the patients were observed for side effects, such as dizziness, headache, allergic reactions, etc.

Palonosetron is quite effective in prevention of PONV compared with ramosetron, ondansetron, and metoclopramide given intravenously for various surgical procedures under general anesthesia. Its effectiveness in PONV provides a new cost-effective agent to the present recital of antiemetic drugs.
