Abstract
Confined and unconfined fallow deer (Dama dama) of the black variety kept at Whipsnade
Park were sedated with etorphine in combination with acepromazine, or xylazine or
both, with or without atropine. Induction, sedation and recovery times were recorded.
During the period under sedation, systemic and pulmonary arterial pressures, electrocardiographs,
body temperature, arterial blood gas pressures and pH, packed cell volume and plasma
electrolytes and enzymes were monitored. In both groups, and with all drug combinations,
heart rates (except where atropine was used and respiratory rates were depressed,
pulmonary arterial pressures were elevated, and blood oxygen tension and pH lowered
compared with interspecies norms. In confined animals, systemic arterial pressures
were depressed. Unconfined animals and animals in which atropine was used showed higher
and more varied systemic arterial pressures and more varied heart rates. Cardiac arrests
occurred in eight animals, five during induction and three during sedation, one of
which was revived with oxygen. Severe arrhythmia occurred in an animal in which atrioventricular
block was confirmed and reversed by oxygen treatment.
