After premedication with intravenous xylazine 30 ponies were anaesthetised for castration under field conditions with intravenous ketamine, thiopentone or methohexitone. The duration of anaesthesia was adequate for surgery and the times taken to stand were similar in each group. The recovery of the ponies after ketamine was quieter than after either of the barbiturates and this may be an advantage when skilled assistance is lacking. However, all the anaesthetics appeared to be suitable for performing minor surgery in the field.
用静脉注射甲苯噻嗪进行预处理后,30匹小马在野外条件下通过静脉注射氯胺酮、硫喷妥钠或美索比妥进行去势麻醉。麻醉持续时间足以进行手术,每组站立所需时间相似。氯胺酮麻醉后小马的恢复比两种巴比妥类药物麻醉后更安静,当缺乏熟练的辅助人员时,这可能是一个优势。然而,所有这些麻醉剂似乎都适合在野外进行小手术。
