一、本文分析了55个肺結核空洞(45个病例)化学疗法治疗一年半以上,气管滴入100次以上疗效不显或无效改用肺导管治疗后的疗效。治疗有效率40％;其中薄壁空洞有效率55.6％,干酪空洞有效率60％,纤維空洞有效率22.7％,硬变空洞无效。空洞閉合率16.4％,其中薄壁空洞閉合率33.4％,干酪空洞30％,纤維空洞及硬变空洞未閉合。痰菌阴轉率为53.3％。二、空洞的类型、洞龄、大小、引流枝气管的通暢度、空洞周围的病变性质、既往治疗等与疗效有密切关系,空洞部位及滴注药物的种类与疗效关系不甚密切。三、治疗过程中的恶化率为12.7％。空洞閉合后随訪3～32个月,空洞复张率为14.3％。
First, this article analyzes 55 tuberculosis cavity (45 cases) chemotherapy for more than a year and a half, less than 100 tracheal instillation or ineffective use of pulmonary catheter therapy. The effective rate of treatment is 40%. The effective rate of thin-walled cavity is 55.6%, the effective rate of cheese cavity is 60%, the effective rate of fiber cavity is 22.7%, and the hard-strain cavity is invalid. The void closure rate was 16.4%, of which the closed rate of thin-wall and void was 33.4%, the cavity of cheese was 30%, and the fibrous and hard-filled cavities were not closed. Sputum negative conversion rate was 53.3%. Second, the type of cavity, cave age, size, the degree of patency of the drainage branch trachea, the nature of the lesions around the cavity, the previous treatment is closely related with the curative effect. The relationship between the type of the empty part and the instillation drug is not closely related to the curative effect. Third, the deterioration rate of the treatment process was 12.7%. After the hole was closed for 3 to 32 months, the void recovery rate was 14.3%.
