الملخص EN

Objective The aim of the study was to assess the effi cacy and safety of palonosetron versus ondansetron for postoperative nausea and vomiting during middle ear surgery.

Patients and methods This study was conducted on 60 patients, ASA I and II, ages ranging between 23 and 48 years, scheduled for middle ear surgery; they were randomly allocated into two equal groups: group 1 received ondansetron (4 mg) intravenously and group 2 received palonosetron (0.25 mg) intravenously.

All medications were given over 30 s immediately before induction of general anesthesia.

The duration of surgery, hemodynamic parameters, the severity and frequency of nausea, retching, and vomiting, time to recovery, and time to discharge of all patients were recorded.

The patient’s requests for rescue antiemetics and details of adverse events throughout the study were recorded.

Results A total of 28 patients in group 2 and 22 patients in group 1 had complete response to antiemetic drugs.

No patient in group 2 needed rescue antiemetic, whereas four patients in group 1 received ondansetron (4 mg) as rescue.

With respect to the severity of nausea, group 2 showed signifi cant decrease in nausea score in comparison with group 1.

With respect to the complications, four patients in group 2 and one patient in group 1 developed headache.

One patient in group 2 had diarrhea.

Conclusion Palonosetron is a good antiemetic alternative during anesthesia with minimal side effects.
