The aim of this study was to report the incidence of anaesthetic complications associated with feline bronchoscopy.
This was a retrospective analysis of anaesthetic records and electronic case logs of feline bronchoscopies at two university hospitals (centres B and L) between January 2013 and December 2015. A two-tailed Fisher's exact test was used for comparison of variables and outcomes between centres.
Seventy-nine cases were included. Desaturation (SpO <90%) was the most frequently encountered complication, reported in 24 cats (30.3%); centre B reported significantly less desaturation than centre L (22.4% vs 52.4%; = 0.014). The use of an endotracheal tube or laryngeal mask airway resulted in a lower incidence of desaturation (22.9% vs 22.2%) than the use of a tracheal catheter through which oxygen was insufflated (48.0%). The latter method was associated with an increased incidence of desaturation ( = 0.034). Patients to which terbutaline was administered had a lower incidence of desaturation (27.5%) than those that did not receive it (35.7%), although this was not statistically significant ( = 0.46). Airway management method and the use of terbutaline differed significantly between centres, as did the profile of complications. Pneumothorax was encountered in two cats (2.5%) and cardiac arrest resulting in the death in one of these cats (1.3%).
Desaturation is a frequently encountered complication during and after bronchoscopy. Airway management method and the use and timing of terbutaline warrant prospective evaluation for their role in decreasing the incidence of desaturation. Bronchoscopy is a high-risk procedure with frequent requirement for post-procedure oxygen supplementation. Pneumothorax and cardiac arrest are potential complications.
本研究旨在报告猫支气管镜检查相关麻醉并发症的发生率。
这是一项对2013年1月至2015年12月间两所大学医院（B中心和L中心）猫支气管镜检查的麻醉记录和电子病例日志进行的回顾性分析。采用双侧Fisher精确检验对各中心之间的变量和结果进行比较。
共纳入79例病例。低氧血症（SpO₂<90%）是最常出现的并发症，24只猫（30.3%）出现该并发症；B中心报告的低氧血症发生率显著低于L中心（22.4%对52.4%；P = 0.014）。使用气管内导管或喉罩气道导致的低氧血症发生率（22.9%对22.2%）低于通过气管导管吹入氧气的方法（48.0%）。后一种方法与低氧血症发生率增加相关（P = 0.034）。接受特布他林治疗的患者低氧血症发生率（27.5%）低于未接受该治疗的患者（35.7%），尽管这在统计学上无显著差异（P = 0.46）。各中心之间气道管理方法、特布他林的使用情况以及并发症情况存在显著差异。两只猫（2.5%）发生气胸，其中一只猫（1.3%）因心脏骤停死亡。
低氧血症是支气管镜检查期间及检查后常见的并发症。气道管理方法、特布他林的使用及其时机在降低低氧血症发生率方面的作用值得进行前瞻性评估。支气管镜检查是一项高风险操作，术后常需要补充氧气。气胸和心脏骤停是潜在并发症。
