Comparison of Nausea and Vomiting Incidence After Laparoscopic Cholecystectomy With Pretreatment With Haloperidol and Ondansetron: A Randomization Clinical Trial Study.

Objective: Nausea and vomiting after surgery are the most common complications. Therefore, we performed this study to compare the effect of ondansetron and haloperidol on nausea and vomiting after laparoscopic cholecystectomy.

Patients And Methods: In this randomized clinical trial, 60 patients candidates for elective laparoscopic cholecystectomy were allocated to haloperidol (0.05 mg/kg, n = 30) and ondansetron (0.15 mg/kg, n = 30) groups. An Ocular Analog Scale was used to assess postoperative nausea and vomiting. Every 15 minutes in the recovery room, heart rate and blood pressure were measured up to 6 hours after surgery. In addition, patient satisfaction was assessed postoperatively.

Results: Haloperidol and ondansetron have the same effect on postoperative nausea and vomiting in the recovery room and ward. It was found that the trend of Visual Analog Scale variable changes in the recovery room was similar in the haloperidol and ondansetron group ( P = 0.58); it was also true for the ward ( P = 0.79). Comparing the length of stay in a recovery room in the 2 groups was not statistically significant ( P = 0.19). In addition, the 2 groups did not differ in satisfaction postoperatively ( P = 0.82).

Conclusion: Haloperidol and ondansetron had an equal effect on reducing nausea and vomiting in the recovery room and ward after laparoscopic cholecystectomy. Patient satisfaction and length of stay in the recovery room did not differ between groups.
