Résumé
The aim of the present study was to compare the antiemetic effect of intravenous Granisetron, Ondansetron & Metoclopramide in a randomized blinded study for prophylaxis of post operative nausea and vomiting (PONV) in patients undergoing laparoscopic cholecystectomy under general anaesthesia. 60 patients (ASA I & II) undergoing laparoscopic cholecystectomy under general anaesthesia were randomly allocated into three equal groups (n=20). Emetic episodes in first 24 hours were recorded and compared in different study groups. Results were analyzed. Minimal emetic episodes were observed in early post-operative period (1-12hrs) in patients who had received intravenous granisetron in comparison to ondansetron and metoclopramide. However, after 12 hours emesis free periods were statistically insignificant between group A and B while patients in group C had no antiemetic effect.
