Comparison of palonosetron and ondansetron in preventing postoperative nausea and vomiting in renal transplantation recipients: a randomized clinical trial

Abstract

Background

End-stage renal diseases patients have a high risk of postoperative nausea and vomiting (PONV), which is multifactorial and need acute attention after renal transplantation for a successful outcome in term of an uneventful postoperative period. The study was done to compare the efficacy of palonosetron and ondansetron in preventing early and late-onset PONV in live donor renal transplantation recipients (LDRT).

Methods

The prospective randomized double-blinded study was done on 112 consecutive patients planned for live donor renal transplantation. Patients of both sexes in the age group of 18...60 years were randomly divided into two groups: Group O (Ondansetron) and Group P (Palonosetron) with 56 patients in each group by computer-generated randomization. The study drug was administered intravenously (IV) slowly over 30.ßseconds, one hour before extubation. Postoperatively, the patients were accessed for PONV at 6, 24, and 72.ßhours using the Visual Analogue Scale (VAS) nausea score and PONV intensity scale.

Results

The incidence of PONV in the study was found to be 30.35%. There was significant difference in incidence of PONV between Group P and Group O at 6.ßhours (12.5% vs. 32.1%, p.ß=.ß0.013) and 72.ßhours (1.8% vs. 33.9%, p.ß<.ß0.001), but insignificant difference at 24.ßhours (1.8% vs. 10.7%, p.ß=.ß0.113). VAS-nausea score was significantly lower in Group P as compared to Group O at a time point of 24.ßhours (45.54.ß...ß12.64 vs. 51.96.ß...ß14.70, p.ß=.ß0.015) and 72.ßhours (39.11.ß...ß10.32 vs. 45.7.ß...ß15.12, p.ß=.ß0.015).

Conclusion

Palonosetron is clinically superior to ondansetron in preventing early and delayed onset postoperative nausea and vomiting in live-related renal transplant recipients.
