title: Use of xylazine sedation with yohimbine antagonism in captive gray wolves.
abstract: Captive gray wolves (Canis lupus) were given 2.2 mg/kg xylazine hydrochloride intramuscularly resulting in profound sedation in 9.1 +/- 0.6 min (mean +/- SE). Heart rate was 42.0 +/- 1.0 beats per minute and respiratory rate was 20.1 +/- 1.6 respirations per minute during sedation. A variety of manipulations could be performed on sedated animals in relative safety. Thirty min after xylazine administration, the animals were given either 0.15 mg/kg yohimbine hydrochloride or 5% dextrose solution intravenously causing recovery in 5.3 +/- 1.0 and 97.1 +/- 14.0 min, respectively (P less than 0.001).
