Abstract

Anaesthesia of wildlife casualties can be challenging. Many patients suffer stress, related not only to disease or injury, but to confinement in captivity. This is exacerbated by restraint and handling and often necessitates the use of sedation or anaesthesia for thorough examination. It is important that the basic principles of good anaesthesia are applied, that the patient and equipment are prepared correctly and that appropriate methods of chemical restraint are chosen.
