Abstract

Objective

To investigate the incidence of peri-anaesthetic complications in dogs undergoing general anaesthesia for thoracic surgery (lateral thoracotomy or median sternotomy) and to identify differences in the rate of peri-anaesthetic complications depending on the surgical approach and American Society of Anesthesiologists (ASA) physical status classification system.

Study design

Retrospective study.

Animals

Dogs that underwent either thoracotomy or sternotomy at The Small Animal Hospital, University of Edinburgh, between January 2019 and August 2022.

Methods

Data recorded included signalment, surgical approach, indication for surgery, general anaesthesia time, surgery time, time to extubation, anaesthetic management and the use of locoregional anaesthetic techniques, neuromuscular blockers, anticholinergics and/or vasopressor and inotropic agents. The occurrence of peri-anaesthetic complications (yes/no) was analysed by surgical approach and ASA classification using chi-square analysis and logistic regression. Statistical significance was set at p < 0.05.

Results

A total of 127 anaesthetic records were reviewed, of which 90 met the inclusion criteria; ASA scores were missing from nine leaving 81. Median sternotomy was associated with a significantly longer surgical (p = 0.03) and anaesthetic time (p < 0.01) as well as the time to extubation (p = 0.023). Hypothermia (n = 72) and hypotension (n = 54) were the most prevalent complications observed despite surgical approach or ASA status. Hypoxaemia was more likely to occur in dogs with ASA status IV (n = 10/29) than in dogs with ASA status II and III (n = 7/52) in chi-square analysis (p = 0.026) and binomial logistic regression (p = 0.046).

Conclusions and clinical relevance

Hypothermia and hypotension were common peri-anaesthetic complications. Higher ASA status was associated with a higher likelihood of hypoxaemia, and no significant association was found between complications and surgical approach. Active warming from the premedication stage and ensuring prompt access to fluid therapy, vasopressors, inotropes and anticholinergics are recommended.

犬行外侧开胸或正中胸骨切开术的围麻醉并发症：一项回顾性研究。

目的：探讨全麻犬胸外科手术（外侧开胸术或正中开胸术）的围麻醉并发症发生率，并探讨不同手术入路和美国麻醉医师协会（ASA）身体状态分类系统对围麻醉并发症发生率的影响。研究设计：回顾性研究。动物：2019年1月至2022年8月期间在爱丁堡大学小动物医院接受开胸或胸骨切开术的狗。方法：记录的数据包括信号、手术入路、手术指征、全麻时间、手术时间、拔管时间、麻醉管理和局部麻醉技术、神经肌肉阻滞剂、抗胆碱能药和/或血管加压药和肌力药物的使用。采用卡方分析和logistic回归分析手术入路和ASA分类，分析麻醉周围并发症（是/否）发生情况。p < 0.05为差异有统计学意义。结果：共审查127份麻醉记录，其中90份符合纳入标准；81人中有9人没有ASA分数。胸骨正中切开术显著延长手术时间（p = 0.03）、麻醉时间（p < 0.01）和拔管时间（p = 0.023）。低温（72例）和低血压（54例）是手术入路或ASA状态下最常见的并发症。卡方分析（p = 0.026）和二项logistic回归分析（p = 0.046）显示，ASA IV状态犬（n = 10/29）较ASA II和III状态犬（n = 7/52）更易发生低氧血症。结论及临床意义：低温和低血压是常见的麻醉周围并发症。ASA水平越高，低氧血症的可能性越高，并发症与手术入路之间没有明显关联。建议从用药前阶段开始积极加热，并确保及时获得液体疗法、血管加压药、肌力药物和抗胆碱能药物。

期刊介绍： Veterinary Anaesthesia and Analgesia is the official journal of the Association of Veterinary Anaesthetists, the American College of Veterinary Anesthesia and Analgesia and the European College of Veterinary Anaesthesia and Analgesia. Its purpose is the publication of original, peer reviewed articles covering all branches of anaesthesia and the relief of pain in animals. Articles concerned with the following subjects related to anaesthesia and analgesia are also welcome: the basic sciences; pathophysiology of disease as it relates to anaesthetic management equipment intensive care chemical restraint of animals including laboratory animals, wildlife and exotic animals welfare issues associated with pain and distress education in veterinary anaesthesia and analgesia. Review articles, special articles, and historical notes will also be published, along with editorials, case reports in the form of letters to the editor, and book reviews. There is also an active correspondence section.
