Antiemetic effect of intravenous palonosetron and ondansetron for the prevention of postoperative nausea and vomiting following laparoscopic surgeries under general anaesthesia, a randomised observational study

Post-operative nausea and vomiting(PONV) is one of the common complications in patients undergoing laparoscopic surgeries under general anaesthesia. This study compares efficacy of prophylactic palonosetron and ondansetron in the prevention of PONV. After obtaining the approval of institutional ethical committee, a prospective randomised study was conducted on 60 patients belonging to American Society of Anaesthesiologists Grade I and II, patients of either sex, aged between 18 to 60 years, fulfilling the inclusion criteria were divided into two groups receiving inj. ondansetron 8 milligrams i.v. or inj. palonosetron 75 micrograms i.v. Incidence of PONV and need of rescue antiemetic was recorded post operatively. Data were evaluated statistically using Graph Pad Prism computer software version 6.04.It was found that inj. palonosetron 75mcg i.v. was more efficient in the prevention of PONV and required lesser rescue antiemetic when compared inj. ondansetron 8mg i.v. At conclusion of the study it was found that the prophylactic usage of inj. palonosetron 75 mcg i.v. is more effective than inj. ondansetron 8mg i.v. in the prevention of PONV in patients undergoing laparoscopic surgery (p value < 0.05).
