This study is a prospective randomized control trial. It is designed to examine the incidence of postoperative nausea and vomiting during 24 hours after elective laparoscopic cholecystectomy in patients receiving preoperative intravenous fluid loading (group F), ondansetron (group O) and receiving neither fluid nor ondansetron or control group (group C). This study is hypothesized that the incidence of PONV in patients receiving preoperative intravenous fluid loading (group F) and patients receiving ondansetron (group O) will be similarly reduced from the control group (receiving neither fluid nor ondansetron).
