长期喉插管的病人约4％发生喉部损伤,多数是轻的,但有0.5—1％的病人是严重的,需经外科处理。插管后喉部的主要病理变化是水肿、溃疡、肉芽形成、喉-气管膜性形成、纤维性粘连及狭窄。最严重的并发症是声门下复发性肉芽肿、声门下狭窄或杓间区纤维性变。本文报导6例严重并发症的治疗经验。并提出下列外科处理方法: 1.气管切开术:必要时作为紧急措施,喉梗阻很少在拔管后2小时内发生。如有感染存在,梗阻可发生于数天后。通常的病理变化是急性喉水肿,但其基本病变是溃疡及肉芽肿。急性
Approximately 4% of patients with long-term laryngeal intubation experience laryngeal lesions, most of them are light, but 0.5-1% of patients are severe and require surgical treatment. The main pathological changes in the larynx after intubation are edema, ulcers, granulation, laryngeal-tracheal membrane formation, fibrous adhesions and stenosis. The most serious complication is subglottic recurrent granuloma, subglottic stenosis, or interspinous fibrosis. This article reports 6 cases of serious complications of treatment experience. And proposed the following surgical methods: 1. Tracheostomy: If necessary, as an emergency measure, laryngeal obstruction rarely occurs within 2 hours after extubation. In case of infection, obstruction can occur in a few days. The usual pathological changes are acute laryngeal edema, but the underlying lesions are ulcers and granulomas. acute
