Abstract

This communication reports a partially reversible chemical immobilization protocol used for translocation and veterinary care in giant otter (Pteronura brasiliensis; GO). Six GOs (three males and three females) weighing 24.8 +/- 4.0 kg (mean +/- SD) and ranging in age from 16 to 42 mo old were anesthetized with an i.m. combination of medetomidine (29 +/- 3 microg/kg) and ketamine (3.9 +/- 0.4 mg/kg). To perform all procedures, two otters required an additional dose of ketamine (1.5 mg/kg). Anesthesia was reversed with atipamezole i.m. (147 +/- 14 mg/kg). The mean induction time and recovery times were 12 +/- 5 and 4 min (range, 0-9 min), respectively, with an anesthesia time of 47 +/- 16 min. According to these results, the combination of medetomidine (30 microg/kg i.m.) and ketamine (4 mg/kg i.m.) is a reasonable choice for inducing anesthesia in GOs.

摘要

本通讯报道了一种用于巨獭（Pteronura brasiliensis；GO）转移和兽医护理的部分可逆化学固定方案。六只巨獭（三只雄性和三只雌性），体重24.8±4.0千克（平均值±标准差），年龄在16至42月龄之间，通过肌肉注射美托咪定（29±3微克/千克）和氯胺酮（3.9±0.4毫克/千克）的组合进行麻醉。为了进行所有操作，两只水獭需要额外注射一剂氯胺酮（1.5毫克/千克）。通过肌肉注射阿替美唑（147±14毫克/千克）逆转麻醉。平均诱导时间和恢复时间分别为12±5分钟和4分钟（范围为0 - 9分钟），麻醉时间为47±16分钟。根据这些结果，美托咪定（30微克/千克肌肉注射）和氯胺酮（4毫克/千克肌肉注射）的组合是诱导巨獭麻醉的合理选择。
