Granisetron Versus Ondansetron: Comparative Effects on ECG, QTc

Summary

Postoperative nausea and vomiting \[PONV\] are common and distressing symptoms after surgery performed under general anaesthesia. 5HT3 antagonists are routinely used for prevention as well as treatment of PONV. After IRB approval we compared the effects of ondansetron and granisetron on the various intervals on ECG in 70 patients undergoing elective surgery for carcinoma breast after written informed consent. The demographic data was collected. The administration of the anaesthetic was left to the discretion of the operating room staff specialist. In the Postoperative Recovery Room patients were randomised to receive 8 mgs of ondansetron or 1 mg of granisetron intravenously. Serial ECGs were recorded at 0 mins (before injection of study drug), 2 mins, 5 mins, 15mins, 1 hour and 2 hours. Pulse rate, Non-invasive blood pressure and SpO2 were also recorded. T
