目的进一步提高对儿童支气管非金属异物的认识和诊断水平。方法回顾性分析1996～2003年92例儿童支气管非金属异物。全部病例进行了胸透检查,59例透视后摄有呼气相或吸气相胸片,22例摄有呼、吸二相胸片。结果①异物多数为植物性异物,其中约2/3为花生。②异物造成支气管阻塞以呼气性活瓣阻塞最多见。X线表现以纵隔移位、摆动最常见。③X线检查诊断阳性率为90.2%,观察纵隔移位、摆动,胸透和胸片具有显著性差异(P<0.01)。结论①X线检查对儿童支气管非金属异物的发现和定位具有重要作用。②观察纵隔移位、摆动胸透优于胸片。③异物阻塞造成的病理改变决定X线表现。
Objective To further improve awareness and diagnosis of bronchial non-metallic foreign bodies in children. Methods A retrospective analysis of 92 children with bronchial non-metallic foreign bodies from 1996 to 2003 was performed. Chest X-ray examination was performed in all cases. There were 59 cases of exhaled or aspirated chest radiographs after fluoroscopy, and 22 cases of radiofrequency and chest radiographs. Results ① The majority of foreign bodies were plant foreign bodies, of which about 2/3 were peanuts. ② foreign body caused by bronchial obstruction to the most common obstruction of the valve. X-ray showed mediastinal shift, the most common swing. The positive rate of X-ray examination was 90.2%. There was a significant difference (P <0.01) in mediastinum shift, swing, chest radiography and chest radiograph. Conclusions ①X-ray examination plays an important role in the detection and localization of bronchial non-metallic foreign bodies in children. ② observation of mediastinal shift, swing chest through better than chest X-ray. ③ obstruction caused by pathological changes determine the X-ray performance.
