Observations on Immobilization of Pere David's Deer

Smithsonian Libraries
Etorphine and xylazine were found to be a safe and reliable drug combination for the immobilization of Pere David's deer, whether excited or unexcited. Excited deer had a longer preimmobilization period, when compared with unexcited deer at comparable dosages. Generally, the acid-base status of Pere David's deer during immobilization was not seriously altered. Deer that had been excited and exercised experienced mild respiratory problems; the unexcited, relatively calm deer experienced minimal acidosis. Significantly high pH and PO2 and significantly lower PCO2 and bicarbonate values were found in the excited deer, when compared with the unexcited deer. Rapid physiologic changes occurred after the intravenous administration of the antagonist, diprenorphine.
