电子支气管镜在小儿不明原因呼吸困难疾病诊断中的应用

Application of electronic bronchoscopy in diagnosis of dyspnea

目的探讨电子支气管镜在小儿呼吸困难疾病中的诊断价值。方法对53例临床表现为呼吸困难且常规内科治疗无明显好转的患儿行电子支气管镜检查,并对临床资料进行回顾性分析。结果53例不明原因呼吸困难患儿中喉-气管-支气管软化22例,气管支气管畸形15例,支气管异物4例,肿瘤或支气管赘生物4例,肺结核1例,肺出血1例,未发现异常6例(考虑炎症所致),总诊断率为88.6%。结论电子支气管镜在小儿呼吸系统疾病中具有诊断和治疗双重作用,值得推广应用。

Objectives To explore the diagnosis value of electronic bronchoscopy in dyspnea in children. Methods All pediatric patients with dyspnea that could not be relieved by medicine were performed by electronic bronchoscopy. The clinical data were analyzed retrospectively. Results Among 53 cases, 22 cases was laryngo-tracheo-bronchomalacia, followed by 15 cases of tracheobronchial anomalies, 4 cases of foreign body, 4 cases of tumor or vegetation, one case of pulmonary tuberculosis, and one case of pneumorrhagia. There were no abnormality in 6 cases and they were mostly likely to be caused by inflammation. Total diagnosis rate was 88.6% （except inflammation）. Conclusions Electronic bronchoscopy has dual applications in diagnosis and therapy of respiratory system diseases in children. It should be recommended and more widely used in clinic.
