Unusually difficult endotracheal intubation was encountered during anesthetic induction of a 41-year-old male, necessitating use of a bronchofiberscope. The usual pre-operative analysis had shown no problems, such as tracheal tumor or stricture. Due to difficult intubation, post-operative evaluations were made and no abnormalities were found. However, investigation of the lateral roentgenogram showed a much greater than average backward bend in the patient's trachea under the vocal cord. It is likely that the sharp bend of the trachea was responsible for difficult intubation.
在对一名41岁男性进行麻醉诱导时，遇到了异常困难的气管插管情况，需要使用支气管纤维镜。常规术前分析未发现气管肿瘤或狭窄等问题。由于插管困难，术后进行了评估，未发现异常。然而，对侧位X线片的检查显示，患者声带下方气管的向后弯曲程度远大于平均水平。气管的急剧弯曲很可能是导致插管困难的原因。
