One-lung ventilation (OLV) is an anaesthetic technique utilised for improved visualisation and access of the surgical field during thoracoscopy. The authors present two cases that underwent OLV with use of a double lumen tube (DLT). The first case was intubated with endoscopic guidance for bronchial port intubation of the right mainstem bronchus. This dog experienced prolonged periods of intraoperative hypoxemia. Upon case review, it was suspected intubation of the mainstem bronchus resulted in occlusion of the right cranial lung lobe. In the second case, the DLT was placed bronchoscopically into the left mainstem bronchus with the aid of computed tomography (CT). Excellent intraoperative oxygenation was achieved. When DLTs are used in dogs, their anatomical differences from humans make them susceptible to additional lung occlusion and pulmonary shunting. Computed tomography is recommended as a fundamental addition to bronchoscopy for correct tube placement.
单肺通气（OLV）是一种麻醉技术，用于在胸腔镜检查期间改善手术视野的可视化和可达性。作者介绍了两例使用双腔管（DLT）进行单肺通气的病例。第一例在支气管镜引导下插管，将支气管端口插入右主支气管。这只狗术中出现了长时间的低氧血症。病例复查时，怀疑主支气管插管导致右颅肺叶阻塞。在第二例中，在计算机断层扫描（CT）辅助下，通过支气管镜将双腔管置入左主支气管。术中实现了良好的氧合。当双腔管用于犬类时，它们与人类的解剖学差异使它们易发生额外的肺阻塞和肺分流。建议将计算机断层扫描作为支气管镜检查的基本补充手段，以确保导管正确放置。
