نبذة مختصرة : Background Retrospective analysis of post-operative vomiting (POV) in non-human primates at our institution was 11%. Based on this additional risk factor for post-operative complications, we aimed to eliminate or decrease POV by adding an antiemetic, maropitant citrate, to the pre-medication protocol. Methods Retrospective and prospective data were collected over a 5-year period from 46 macaques of two species during 155 procedures. Additionally, blood was collected from five Macaca mulatta to perform a pharmacokinetic analysis. Results A 1 mg/kg subcutaneous dose of maropitant given pre-operatively significantly decreased POV. Findings indicated post-neurosurgical emesis in Macaca fasicularis was significantly greater than in Macaca mulatta. Pharmacokinetic analysis of maropitant in Macaca mulatta determined the mean maximum plasma concentration to be 113 ng/mL. Conclusions Maropitant administration prior to anesthesia for neurosurgeries decreased our incidence of POV to 1%. The plasma concentration reaches the proposed plasma level for clinical efficacy approximately 20 minutes after administration.
