RANDOMIZED COMPARATIVE STUDY OF ONDANSETRON AND COMBINATION OF ONDANSETRON AND DEXAMETHASONE, AS A PROPHYLAXIS OF POST-OPERATIVE NAUSEAAND VOMITING IN ADULTS UNDERGOING ELECTIVE LAPAROSCOPIC SURGERIES

Abstract

Background: Post-operative nausea and vomiting (PONV) is quite associated with laparoscopic surgery. In-spite of advances in surgery and post surgical care, nausea and vomiting still has a high incidence. This study was planned to explore the efcacy of a combination therapy of ondansetron with dexamethasone against PONVand compare the results with the efcacy of ondensetron-only. Method:Arandomized clinical trial study was conducted in the Department of Anesthesia, GMC Jammu, over a period of 6 months, on 50 patients in the age group of 18-50 years, of either gender, undergoing laparoscopic surgeries under general anesthesia. Patients were divided into two groups of 25 each: Group A received 4 mg of Ondansetron intravenously, while Group B received 4 mg of Ondansetron and 8 mg of Dexamethasone intravenously, soon after intubation. Results: The demographic variables of two groups were similar. While 19 (76%) patients showed post-operative nausea in Group A, while in Group B, only 8 (32%) patients experienced nausea, which was very signicant. Similarly, 11 (44%) patients showed post-operative vomiting in GroupAand only 2 (8%) complained of vomiting. 24% patients did not complain about any kind of nausea or vomiting in GroupA. Mild nausea was observedin60%patientsinGroupA,while amongonly32%patientsingroupB.Nocomplications of anykindwereobservedduringthisstudy. Conclusion: Ondensetron and dexamethasone, administered intravenously, after intubation, in laparoscopic surgery, is safe and has a better patient response in preventing post-operative nausea and vomiting.
