喉罩通气全麻下经纤维支气管镜支架置入治疗重度气道狭窄

Treatment of severe airway stenosis by stent implantation of fibrobronchoscopy under laryngeal mask anaesthesis

目的探讨喉罩通气全麻下经纤维支气管镜支架置入技术在重度气道狭窄中的应用。方法采用喉罩通气下全身麻醉后行纤维支气管镜支架置入术,观察治疗前后患者气道直径、气促症状的改善情况。结果喉罩均一次放置成功,16例患者治疗后完全有效11例(68.6%),部分有效5例(31.3%),近期有效率100%。气促指数由(3.63±0.57)下降为(1.53±0.72),气道直径由(3.33±2.12)mm扩大为(11.78±4.8)mm(P<0.05)。结论喉罩通气全麻下经纤维支气管镜支架置入是一种治疗重度气道狭窄安全、有效的新方法。

[ Objective ] To evaluate the effect of stent implantation of fibrobronchoscopy under the laryngeal mask anaesthesis in the treatment of severe airway stenosis. [Methods] Patients were treated with stent implantation of fibrobronchoscopy under the laryngeal mask anaesthesis. Airway diameters, dyspnea index were evaluated before and after management. [Results] All laryngeal masks were implanted successfully at the first time. There was full effectiveness in 11 cases （68.6%）, partial in 5 cases （31.3%） and the total effective rate was 100%. Dyspnea index decreased from （3.63±0.57） to （1.53±0.72）, airway diameter increased from （3.33±2.12） mm to （11.78±4.8） mm （P〈0.05）. [Conclusions] Stent implantation of fibrobronchoscopy under the laryngeal mask anaesthesis is an efficient, safe method for treatment of severe airway stenosis.
