A 62 year old male with a right pyriform fossa lesion extending to the right arytenoid and obscuring the glottic inlet was planned for laser assisted excision. Direct laryngoscopic assessment after topicalization of the airway, showed a Cormack Lehane grade 3 view. We report a case where, in the absence of a fiberscope, a novel inexpensive Universal Serial Bus camera was used to obtain an optimal laryngoscopic view. This provided direct visual confirmation of tracheal intubation with a Laser Flex tube, when capnography failed to show any trace. Capnography may not be reliable as a sole indicator of confirmation of correct endotracheal tube placement. Video laryngoscopy may provide additional confirmation of endotracheal intubation.
一位 62 岁男性，右侧梨状窝病变延伸至右侧杓状软骨并遮挡声门入口，计划行激光辅助切除。气道表面麻醉后直接喉镜评估显示 Cormack Lehane 分级 3 级。我们报告了一例在没有纤维喉镜的情况下，使用新型廉价通用串行总线（USB）摄像头获得最佳喉镜视野的病例。当二氧化碳描记法未能显示任何痕迹时，这为使用激光 Flex 管进行气管插管提供了直接的视觉确认。二氧化碳描记法可能不可靠，不能作为确认气管内导管放置正确的唯一指标。视频喉镜可提供气管插管的额外确认。
