We captured 10 free-ranging desert mule deer (Odocoileus hemionus crooki) (five males and five females) by net-gun from a helicopter and immobilized them with xylazine hydrochloride (HCl) (100 mg) and ketamine HCl (300 to 400 mg) injected intramuscularly. Arousal and ambulation times were 13.9 +/- 4.2 and 14.3 +/- 4.2 min in eight deer injected intravenously with tolazoline HCl (3.0 mg/kg). We observed a curvilinear relationship (R = 0.50, P less than 0.01) between rectal temperature and time after induction of anesthesia. Mean peak temperature (41.4 C) occurred at 23.7 +/- 3.2 min postinduction and was greater (P less than 0.01) than the mean temperature measured initially (40.8 C). Heart and respiratory rates (108 beats/min and 75 breaths/min) were elevated prior to immobilization. Mean heart rate increased (P less than 0.05) from 90 +/- 9 beats/min in anesthetized deer to 120 +/- 13 beats/min after tolazoline HCl injection. A 20% capture-related mortality rate suggests this combination of physical and chemical capture has serious limitations. Captive deer permitted to recover from xylazine HCl-ketamine HCl immobilization without a reversal agent were able to walk in 290 +/- 79 min.
我们从直升机上用网枪捕获了10只自由放养的沙漠骡鹿（Odocoileus hemionus crooki）（5只雄性和5只雌性），并用盐酸赛拉嗪（100毫克）和盐酸氯胺酮（300至400毫克）肌肉注射使其麻醉。对8只静脉注射盐酸妥拉唑啉（3.0毫克/千克）的鹿进行观察，其苏醒时间和行走时间分别为13.9±4.2分钟和14.3±4.2分钟。我们观察到直肠温度与麻醉诱导后的时间呈曲线关系（R = 0.50，P<0.01）。平均峰值温度（41.4℃）出现在诱导后23.7±3.2分钟，高于初始测量的平均温度（40.8℃）（P<0.01）。在麻醉前，心率和呼吸频率（分别为108次/分钟和75次/分钟）升高。平均心率从麻醉鹿的90±9次/分钟增加（P<0.05）到注射盐酸妥拉唑啉后120±13次/分钟。20%的捕获相关死亡率表明这种物理和化学捕获的组合存在严重局限性。在没有使用苏醒剂的情况下，从盐酸赛拉嗪-盐酸氯胺酮麻醉中恢复的圈养鹿能够在290±79分钟内行走。
