The aim of this study was to report the anaesthetic management and peri-anaesthetic complications of 57 dogs undergoing pacemaker implantation at a referral institution over 10 years (2002-2012). The median duration of the procedure was 135 minutes (range 25-260 minutes). Patients were classified as American Society of Anaesthesiologist (ASA) III (42 cases) and ASA IV (15 cases). Forty-three patients had third-degree atrioventricular block, and 14 patients had sick sinus syndrome. The anaesthetic protocol most frequently chosen was pethidine (41 cases), etomidate-midazolam (43 cases) and isoflurane in oxygen for maintenance (57 cases). Transthoracic external pacing was used (43 cases) until the internal pacing lead was implanted. Atracurium was administered (48 cases) and intermittent positive pressure ventilation was applied in 52 cases. Complications observed included hypothermia (19 cases) and hypotension (5 cases). Three patients died (5.8%, 95% CI 1.1% to 14.6%) within the first 48 hours after termination of anaesthesia. The outcome for this procedure in sick animals appeared generally good though a number of complications were documented.
本研究旨在报告10年间（2002 - 2012年）在一家转诊机构为57只犬进行起搏器植入手术的麻醉管理及围麻醉期并发症。手术的中位持续时间为135分钟（范围25 - 260分钟）。患者分为美国麻醉医师协会（ASA）Ⅲ级（42例）和ASAⅣ级（15例）。43例患者患有三度房室传导阻滞，14例患者患有病态窦房结综合征。最常选用的麻醉方案为哌替啶（41例）、依托咪酯 - 咪达唑仑（43例）以及异氟烷 - 氧气维持麻醉（57例）。在植入心内起搏导线前使用经胸体外起搏（43例）。使用阿曲库铵（48例），52例采用间歇正压通气。观察到的并发症包括体温过低（19例）和低血压（5例）。3例患者（5.8%，95%置信区间1.1%至14.6%）在麻醉结束后的最初48小时内死亡。尽管记录了一些并发症，但患病动物接受该手术的总体预后似乎良好。
