The Use of Etorphine Hydrochloride (M99) in the Capture and Immobilization of Wild Dingoes, Canis Familiaris Dingo.

Abstract

Etorphine hydrochloride (M99) with acetylpromazine was tested as an immobilizing agent for captive or trapped dingoes by injections, and for free wild dingoes by darting. A dose of 0.5 mg M99 with 2.5 mg acetylpromazine immobilized dingoes rapidly, with complete analgesia, and with no apparent ill effects over a wide range of dose per unit weight, although hypothermia and tachycardia were always observed. Analgesia was sufficient for a number of physiological samples to be taken. A dose of 0.5 mg cyprenorphine hydrochloride revived the dingoes rapidly.
