Even when performed by an experienced physician, endotracheal intubation is more traumatic than previously supposed. Following emergency intubation, patients have little probability of having a normal larynx. One-hundred patients underwent CT scan of the larynx 6 months or more following endotracheal intubation of short duration (up to 8 h). Ten patients (Group 1) with respiratory arrest underwent emergency intubation; 90 surgical patients (Group 2) underwent anesthesia with endotracheal intubation. Indirect laryngoscopy was performed in 59 symptomatic patients. Abnormal CT findings were present in 86 out of 100 patients. CT irregularities, which included tears, scars and small laryngoceles, were noted on indirect laryngoscopy in 59 symptomatic patients. The laryngeal damage following endotracheal intubation is surprisingly high.
即使由经验丰富的医生进行，气管插管造成的创伤也比之前认为的更大。紧急插管后，患者喉部恢复正常的可能性很小。100例患者在短时间（最长8小时）气管插管6个月或更长时间后接受了喉部CT扫描。10例呼吸骤停患者（第1组）接受了紧急插管；90例外科手术患者（第2组）接受了气管插管麻醉。对59例有症状的患者进行了间接喉镜检查。100例患者中有86例CT检查结果异常。59例有症状的患者在间接喉镜检查中发现了包括撕裂、瘢痕和小喉膨出在内的CT异常。气管插管后的喉部损伤惊人地高。
