A 22-yr-old male had a head injury after a road traffic accident. His trachea was intubated for 5 days with a high-volume, low-pressure cuffed tracheal tube. When the trachea was extubated he showed signs of progressive upper airway obstruction which were relieved by tracheotomy. Computed axial tomography demonstrated complete tracheal obliteration at the previous cuff site. The patient underwent resection anastomosis of the destroyed tracheal segment which, on histological examination, showed fibrous tissue and bone formation. It is believed that excessive cuff pressure was the cause of the damage, as monitoring cuff pressure has not yet become a routine practice in anaesthesia and intensive care.
一名22岁男性在道路交通事故后头部受伤。他使用大容量、低压带套囊气管导管进行气管插管5天。气管拔管时，他出现进行性上气道梗阻迹象，气管切开术后梗阻缓解。计算机断层扫描显示先前套囊部位气管完全闭塞。患者接受了受损气管段的切除吻合术，组织学检查显示有纤维组织和骨形成。据信，套囊压力过高是造成损伤的原因，因为在麻醉和重症监护中监测套囊压力尚未成为常规做法。
