Chemical immobilization of chimpanzees (Pan troglodytes) using a combination of detomidine and ketamine

The combination detomidine (60 μg kg−1) and ketamine (5-6 mg kg−1) can be used for the immobilization of chimpanzees for non- to minimally invasive procedures. A period of 15 minutes should be allowed before handling to avoid unwanted arousal. Oxygen administration is recommended to reduce hypoxaemia. Administration of atipamezole is justified to hasten recovery.
