摘要

鬃毛树懒(Bradypus torquatus)是巴西两个州的特有濒危物种,有许多未知的生物信息需要用于指导保护行动。对其他树懒物种进行过麻醉研究,但对鬃毛树懒的麻醉研究还很缺乏。我们收集了 12 只放养的鬃树懒的麻醉数据,这些树懒被固定起来进行野外检查。这些个体使用氯胺酮(4.0 毫克/千克)和美托咪定(0.03 毫克/千克)进行麻醉,并使用阿替巴唑(0.1 毫克/千克)进行拮抗。记录诱导和恢复时间,并与性别和年龄进行比较。诱导后至使用拮抗剂前,每隔 10 分钟记录一次麻醉期间的生理参数(直肠温度、心率、呼吸频率和血氧饱和度),并随时间变化进行统计评估。与其他研究相比,诱导时间较快(3.21 ± 0.76),但恢复时间较长(113.3 ± 18)。不同性别和年龄组的诱导和恢复时间没有差异。直肠温度、心率和血氧饱和度在整个过程中保持稳定。随着时间的推移,呼吸频率明显下降,从每分钟 18.25 ± 7.03 次下降到 13.17 ± 3.66 次。我们的研究结果表明,氯胺酮和美托咪定的组合是对鬃树懒进行麻醉的一种安全有效的选择。

FIRST REPORT OF CHEMICAL IMMOBILIZATION AND PHYSIOLOGICAL PARAMETERS FOR FREE-RANGING MANED SLOTH (BRADYPUS TORQUATUS), USING A COMBINATION OF KETAMINE AND MEDETOMIDINE.

The maned sloth (Bradypus torquatus) is an endemic and endangered species of two Brazilian states, with much unknown biological information needed to direct conservation actions. Other sloth species have been studied regarding anesthesia; however, there is a lack of anesthesia research for the maned sloth. Anesthetic data were collected from 12 free-range maned sloths that were immobilized for a field examination. Individuals were anesthetized using a combination of ketamine (4.0 mg/kg) and medetomidine (0.03 mg/kg), and antagonized with atipamezole (0.1 mg/kg). Time to induction and recovery were recorded and compared with sex and age classes. After the induction and until antagonist administration, physiological parameters (rectal temperature, heart rate, respiratory rate, and oxygen saturation) were recorded every 10 min during anesthesia and were statistically evaluated over time. Induction was fast (3.21 ± 0.76), but recovery was longer (113.3 ± 18) when compared to other studies. Induction and recovery times were not different across sex or age classes. Rectal temperature, heart rate, and oxygen saturation remained stable throughout the procedure. Respiratory rate significantly decreased over time, from 18.25 ± 7.03 to 13.17 ± 3.66 movements per minute. Our results indicate that the described combination of ketamine and medetomidine is a safe and effective choice for anesthesia of maned sloths.

期刊介绍: The Journal of Zoo and Wildlife Medicine (JZWM) is considered one of the major sources of information on the biology and veterinary aspects in the field. It stems from the founding premise of AAZV to share zoo animal medicine experiences. The Journal evolved from the long history of members producing case reports and the increased publication of free-ranging wildlife papers. The Journal accepts manuscripts of original research findings, case reports in the field of veterinary medicine dealing with captive and free-ranging wild animals, brief communications regarding clinical or research observations that may warrant publication. It also publishes and encourages submission of relevant editorials, reviews, special reports, clinical challenges, abstracts of selected articles and book reviews. The Journal is published quarterly, is peer reviewed, is indexed by the major abstracting services, and is international in scope and distribution. Areas of interest include clinical medicine, surgery, anatomy, radiology, physiology, reproduction, nutrition, parasitology, microbiology, immunology, pathology (including infectious diseases and clinical pathology), toxicology, pharmacology, and epidemiology.
