OBJECTIVE: To describe the complications with elective orthopaedic MRI of horses, mules, and donkeys under general anaesthesia without the use of peri-anaesthetic antimicrobial prophylaxis at a single large tertiary referral centre. We hypothesised that horses, mules, and donkeys undergoing general anaesthesia for elective orthopaedic MRI, without antimicrobial prophylaxis, will not be at increased risk of complications, including increased risk of infectious respiratory disease.
METHODS: Retrospective cross-sectional study.
METHODS: This retrospective study of 1798 systemically healthy equids that underwent elective orthopaedic MRI under general anaesthesia without peri-anaesthetic antimicrobial prophylaxis between January 2009 and May 2020.
RESULTS: A total of 1655 MRIs were included in the study, with 25 (1.5%) horses having complications. The most common complication was post-anaesthetic fever in 11 (0.7%) horses, of which 4 (0.2%) horses went on to develop pneumonia and one horse was diagnosed with equine herpesvirus (respiratory). Seven (0.4%) horses developed transient post-anaesthetic femoral neuropathy and 7 (0.4%) horses had mild post-anaesthetic colic that resolved with initial medical management. No horses were euthanised or died in this study.
CONCLUSIONS: The retrospective nature of the study led to non-randomised case selection, and some records were incomplete.
CONCLUSIONS: These findings suggest that peri-anaesthetic antimicrobial prophylaxis may not be necessary for performance and sport horses undergoing general anaesthesia for elective orthopaedic MRI.
目的:描述马选择性矫形MRI的并发症,骡子,和驴在全身麻醉下,没有在一个大型三级转诊中心使用周围麻醉抗菌药物预防。我们假设马,骡子,和接受全身麻醉的驴进行选择性骨科MRI,没有抗菌预防,不会增加并发症的风险,包括传染性呼吸道疾病的风险增加。
方法:回顾性横断面研究。
方法:本回顾性研究于2009年1月至2020年5月期间,对1798名全身健康的动物进行了择期骨科MRI检查,在全身麻醉下没有进行围麻醉抗菌药物预防。
结果:本研究共纳入1655个MRI,25(1.5%)马有并发症。最常见的并发症是11匹(0.7%)马的麻醉后发热,其中4匹(0.2%)马继续发展为肺炎,一匹马被诊断患有马疱疹病毒(呼吸道)。7匹(0.4%)马发生了短暂性麻醉后股骨神经病,7匹(0.4%)马发生了轻度麻醉后绞痛,并通过最初的医疗管理解决。在这项研究中没有马匹被安乐死或死亡。
结论:本研究的回顾性性质导致非随机病例选择,有些记录不完整.
结论:这些研究结果表明,对于选择骨科MRI进行全身麻醉的表演和运动马,可能不需要预防周围麻醉抗菌药物。
