The aim of the study was to compare the effect of naphthylmedetomidine to medetomidine on the behavior of orangutans and chimpanzees. Methods: The immobilization was performed as part of a medical examination in five chimpanzees and three orangutans.
Following pre-medication with midazolam (0.70-1.20 mg/kg p.o.), naphthylmedetomidine (50-70 mu g/kg), or medetomidine (20-30 mu g/kg) was given with ketamine (3 mg/kg) and hyaluronidase (150 M.U.) into musculus deltoideus
