A 68-year-old patient was scheduled for a thoracotomy. A double-lumen endobronchial tube was requested by the surgeon to facilitate operating conditions. Initial attempts at intubation by conventional methods were unsuccessful. The proximal ends of a 37F double-lumen tube were then shortened and a 4-mm fibreoptic bronchoscope was passed through the bronchial lumen. The patient's larynx was easily visualized and the bronchoscope was passed into the trachea. The double lumen tube was then advanced over the bronchoscope and correctly positioned. Shortening a double-lumen tube allows the use of a fibreoptic bronchoscope to aid in tracheal intubation in a patient whose larynx is difficult to visualize by conventional methods.
一名68岁患者计划进行开胸手术。外科医生要求使用双腔支气管导管以利于手术操作。最初尝试用传统方法插管未成功。然后将一根37F双腔导管的近端缩短，并将一根4毫米的纤维支气管镜经支气管腔插入。患者的喉部很容易看清，纤维支气管镜被插入气管。然后将双腔导管顺着纤维支气管镜推进并正确定位。缩短双腔导管可在通过传统方法难以看清喉部的患者中使用纤维支气管镜辅助气管插管。
