Abstract: ObjectiveTo improve the diagnosis and cure rate of complicated trachea or bronchus foreign bodies. MethodsThe clinical data of 4 cases of complicated trachea or bronchus foreign bodies from June 2004 to June 2007 were retrospectively analyzed. Results2 cases received rigid bronchoscopies two times because of foreign body inlaying but avoided thoracotomy. 1 case of pairs of side bronchi foreign bodies received one operation. 1 case of upper lobe bronchus foreign body was partly taken out, one month later its residue happened to be coughed out. ConclusionsWe should make a full preparation before the operations. The fiberoptic bronchoscopy for a foreign body should be suitable for children above 3 years old. Whether patients with trachea or bronchus foreign bodies should be carried on a routine CT inspection still deserves discussion. A define foreign body can be fetched hard. For the fragile foreign body, we should pay attention to possible multiple ones in the trachea or bronchi. Also there should be such simple apparatus as a crocodile clamp in the emergency room to rapidly remove foreign bodies inlaid in the glottis.
