Orotracheal intubation in dogs is a common and easily-performed procedure that provides a patent airway during anaesthesia. In dogs with temporomandibular joint ankylosis or pseudo-ankylosis, airway management can be a challenging procedure since these dogs have a limited ability to open their mouth. Methods to provide safe, uneventful intubation in such patients may include minimally invasive techniques such as retrograde intubation using a guide wire and fibre-optic-aided laryngoscopy.
We report a case of a 16-month-old, intact female Bull Terrier weighing 17 kg, admitted to the hospital for surgical treatment of bilateral ankylosis of the temporomandibular joint. Intubation was achieved, without direct observation of the larynx, by retrograde intubation using a vascular access catheter and a vascular wire guide through cricothyroid membrane. Bilateral condylectomy was performed and the dog recovered uneventfully.
In conclusion, retrograde intubation was relatively simple to perform with the guide wire technique and no specific training or equipment were necessary.
犬经口气管插管是一种常见且易于实施的操作，可在麻醉期间提供通畅气道。对于患有颞下颌关节强直或假性强直的犬，气道管理可能具有挑战性，因为这些犬张嘴能力有限。在此类患者中提供安全、平稳插管的方法可能包括微创技术，如使用导丝逆行插管和纤维光学辅助喉镜检查。
我们报告一例16个月大、体重17千克的未绝育雌性牛头梗，因双侧颞下颌关节强直入院接受手术治疗。通过使用血管通路导管和血管导丝经环甲膜逆行插管，在未直接观察喉部的情况下成功插管。实施了双侧髁突切除术，犬恢复顺利。
总之，使用导丝技术进行逆行插管相对简单，无需特殊培训或设备。
