气管狭窄是长期气管插管和气管切开令人担忧的并发症。其发生率在气管切开为0.6～21%,喉气管插管为6～21%。在Mississippi医疗中心1969～1990年收治的43例气管狭窄中,32例为气管内狭窄,并着重对其术式选择和疗效进行分析。因气管插管和或气管切开而致狭窄者25例占58%(25/43)。诊断是依据X线平片及CT,必要时经MRI检查确定。狭窄的类型和长度则据内窥镜检查评估。狭窄的程度分:管腔阻塞小于70%为轻度;阻塞71～90%为中度;如阻塞大于90%为重度。32例 Tracheal stenosis is a worrying complication of long-term endotracheal and tracheostomy. The incidence of tracheostomy in 0.6 to 21%, laryngeal intubation of 6 to 21%. Of the 43 tracheal stenoses admitted to the Mississippi Medical Center from 1969 to 1990, 32 were endotracheal stenoses, and their surgical options and efficacy were analyzed. Twenty-five patients (58%) had stenosis due to endotracheal intubation or tracheotomy (25/43). Diagnosis is based on X-ray and CT, if necessary, determined by MRI examination. The narrow type and length are assessed by endoscopy. Narrow degree of points: less than 70% lumen obstruction is mild; 71 to 90% of the obstruction is moderate; if more than 90% of the obstruction is severe. 32 cases
