Background and Aims: Postanesthesia shivering (PAS) is a common, distressing experience. Ondansetron, the classical 5HT3 antagonist has been in use for its prevention since long. Palonosetron, a newly introduced potent antiemetic drug with better pharmacodynamics is currently in use by clinicians. Hence, a study was conducted to compare the efficacy of ondansetron and palonosetron in preventing PAS in patients undergoing elective lower segment caesarean section (LSCS) under spinal anaesthesia. Material and Methods: A total of 84 patients scheduled for elective LSCS under spinal anesthesia were randomly allocated to one of the two study groups (Group O & P). Accordingly, 8 mg of ondansetron or 0.075 mg palonosetron was administered in the same volume intravenously 30 min preoperatively. Sublingual temperature was recorded regularly. All patients were observed for 90 min postspinal for PAS. Observations were analyzed statiscally. Results: No statistically significant intergroup difference was observed in the duration of surgery, and sublingual temperature. However, statistically significant difference was recorded for PAS (23.8% in ondansetron group, 9.5% in palonosetron group). Conclusion: Prophylactic administration of palonosetron significantly reduced incidence of PAS compared to ondansetron. However, further studies with larger sample size and more heterogeneous groups are suggested.
