【摘要】 目的探讨临近I度呼吸困难的双侧声带麻痹患者声门面积以及双侧声带麻痹拔除气管套管的声门面积依据。方法选择临近I度呼吸困难的双侧声带麻痹患者14例,用Olympus电子喉镜、测长仪及GEME2000软件,测量分析声门参数,同时对患者身高、体重及体表面积进行测算。结果声门面积最小为31.00mm2,最大为43.23mm2,统计学逐步回归分析发现,临近呼吸困难的声门面积与体表面积呈线性相关。回归方程为S声门面积=8.412+18.873S体表面积。结论回归方程为临近呼吸困难声门最大开放面积提供较为准确、简便的计算方法 。根据体表面积,也可估测出所有欲解除双侧声带麻痹的呼吸困难、拔除气管套管至少需具有的声门面积。更多还原

【Abstract】 OBJECTIVE To study the size of glottic area on bilateral vocal cords paralysis near to dyspnea degree I,and provide basis of the glottic area for decannulation after tracheotomy due to bilateral vocal cords paralysis.METHODS Fourteen cases were selected according to the criterion.Glottic parameters were measured with electrolaryngoscopy,length metrical apparatus and GEM2000 software.At the same time,the patient’s height,body weigh and the body surface area were measured.RESULTS The minimal glottic area was 31.00 mm 2,and maximal glottic area was 43.23 mm 2.Stepwise regression found the size of glottic area linearly correlated with body surface area.The regression equation is S(glottic area,mm 2)=8.412+18.873S(body surface area,m 2).CONCLUSION An accurate and convenient way was provided through this equation with body surface area to calculate maximal inspiratory glottic area on bilateral vocal cords paralysis near to dyspnea degree I.Furthermore,the size of glottic area that the patient must at least posses on bilateral vocal cord paralysis for decannulation can also be estimated according to patient’s body surface area.更多还原
