目的探讨胸部X线检查在小儿气管支气管异物的诊断价值。方法对我院2005年1月-2012年6月收治的经异物取出而确诊的95例气管或支气管异物患儿的术前胸部X线结果进行回顾性分析。结果 95例气管支气管异物患儿中有92例接受了胸片及胸透检查,发现间接征象83例(90.2%),13例气管异物中10例有条件做胸部X线检查,占76.9%,其中纵隔摆动1例(10%);82例支气管异物均胸部X线检查,发现纵隔摆动为92.7%,两组纵隔摆动发生率统计学有差异性意义(P<0.05)。支气管异物发生纵隔摆动的76例患儿中出现呼气性活瓣阻塞(61.8%)明显多于吸气性活瓣阻塞(38.2%),P<0.05。结论胸透+胸部正位片对小儿气管支气管异物的诊断价值重大,是最主要的检查方法之一。
Objective To investigate the diagnostic value of chest X-ray in children with tracheobronchial foreign bodies. Methods The preoperative chest X-ray findings of 95 children with tracheal or bronchial foreign bodies confirmed by foreign body removal from January 2005 to June 2012 in our hospital were analyzed retrospectively. Results Of the 95 children with tracheobronchial foreign bodies, 92 (92.2%) had chest X-ray and chest X-ray examination and 83 cases (90.2%) had indirect signs. Thirteen of 13 tracheal foreign bodies were eligible for chest X-ray examination, accounting for 76.9% One case of mediastinum swing (10%); 82 cases of bronchial foreign body chest X-ray examination, found that mediastinum swing was 92.7%, two sets of mediastinum swing statistically significant difference (P <0.05). Among the 76 children who developed mediastinum swinging, the occlusion of the expiratory valve (61.8%) was significantly more than that of the inhalation valve (38.2%), P <0.05. Conclusion Chest thoracoscopy + chest anteroposterior diagnosis of pediatric tracheobronchial foreign body is significant, is one of the most important methods of examination.
