目的：探讨气管支气管异物患儿延误诊断的原因，以减少误诊率。方法：对初诊为“气管支气管炎”而最后确诊为气管支气管异物36例患儿的临床资料进行回顾性分析。结果：无异物吸入史患儿31例，呼吸音改变患儿32例，单侧或单个肺叶呼吸音减弱患儿31例，肺三维CT可见肺叶气肿和气管堵塞。结论：无异物吸入史是气管支气管异物延误诊断的主要原因。%Objective:To explore the causes of delayed diagnosis of tracheobronchial foreign bodies in children, in order to re-duce the rate of misdiagnosis. Methods:Clinical data of 36 cases with first diagnosed as"bronchitis" and finally diagnosed as tracheo-bronchial foreign bodies were analyzed retrospectively. Results:No foreign-body aspiration history was found in 31 cases, respiratory sound changes in 32 cases, decreased breath sounds of unilateral or a single lobe in 31 cases. Lobar emphysema and airway blockage were seen in pulmonary Three-dimensional CT. Conclusions:No history of foreign-body aspiration is the main reason for the delayed diagnosis of the tracheobronchial foreign bodies.
