Two reports concerning difficulties at insertion of a minitracheostomy cannula are presented. In one patient, a minitracheostomy tube perforated the posterior wall of the trachea, resulting in pneumomediastinum. In another patient, conventional signs, i.e. airflow and passing of a suction catheter through the cannula, were misleading in assessing the position of the tube. Fiberoptic tracheoscopy immediately after the performance of minitracheostomy revealed the position of the cannula in both cases.
本文报告了两例关于微创气管切开套管插入困难的病例。其中一例患者，微创气管切开导管穿透了气管后壁，导致纵隔气肿。另一例患者中，传统的判断指标，即气流和吸痰管能否通过套管，在评估导管位置时产生了误导。两例患者在微创气管切开术后立即进行纤维支气管镜检查均明确了套管的位置。
