Postoperative nausea and vomiting (PONV) is an undesirable clinical condition that increases the likelihood of dehiscence, bleeding, pulmonary aspiration of gastric contents, and electrolyte loss that lead to increased costs, prolonged hospital stays, and delayed recovery. In recent years, selective serotonin 5-hydroxytryptamine sub-type 3 (5-HT3) receptor antagonists such as ondansetron, granisetron, palonosetron have been introduced because they are effective in the prevention and treatment of PONV in bariatric surgery. In this study, the effects of ondansetron and palonosetron on PONV in patients who undergo sleeve gastrectomy will be compared.
Evaluate the safety and efficacy of palonosetron versus ondansetron to reduce and control post-operative nausea in bariatric surgery.
