Orotracheal intubation is a commonly performed procedure in the cat, but it is not without complications. Tracheal rupture has been reported in cats, but trauma to the arytenoids from intubation has not been documented.
An otherwise healthy, 5-year-old male domestic shorthair cat presented for total ear canal ablation to resolve intractable otitis media and externa. The cat was premedicated with glycopyrrolate, hydromorphone, and acepromazine. Anesthesia was induced with diazepam and ketamine, and maintained with isoflurane in oxygen. During orotracheal intubation, the larynx was poorly visualized and excessive force was used to perform intubation. Subsequently, blood was observed in the larynx and laryngoscopy revealed a tear lateral to the patient's right arytenoid which had been created during intubation. The larynx was re-intubated normally and the cat suffered no obvious ill effects from the trauma to the larynx.
Direct observation and proper technique must be employed during orotracheal intubation in cats in an attempt to avoid laryngeal trauma.
经口气管插管是猫科动物中常见的操作，但并非没有并发症。猫科动物中曾有气管破裂的报道，但插管导致杓状软骨损伤尚未见文献记载。
一只5岁、健康的雄性家养短毛猫因顽固性中耳炎和外耳炎前来接受全耳道切除术。该猫术前使用了格隆溴铵、氢吗啡酮和乙酰丙嗪进行预处理。用安定和氯胺酮诱导麻醉，并在氧气中用异氟醚维持麻醉。在经口气管插管过程中，喉部视野不佳，插管时用力过大。随后，在喉部观察到血液，喉镜检查显示患者右杓状软骨外侧有一处在插管过程中造成的撕裂伤。喉部正常重新插管，该猫未因喉部创伤出现明显不良影响。
猫经口气管插管时必须采用直接观察和正确技术，以避免喉部创伤。
