ABSTRACT

A study on 21 cases of the missing foreign body in respiratory tract caused the relapsed bronchopneumonia in 98 children admitted to the Institute of pediatry during 6/1998- 6/2000 diagnosed by the broncho-endoscopy has shown that the missing foreign body was an important and common cause of the relapsed bronchopneumonia in male children with ages of 1-5. The foreign bodies located mainly in the right broncho- alveolar, especially anterior basal branch of hyporterial bronchus. They had a less photo absorption property and usually are seeds. The clinical symptoms were long-lasting cough, productive cough, bleeding cough. The pathological respiratory sound in brochus with foreign body clearlier than this in the normal side. The organic foreign bodies cause the more severe infection and many times of relapses.
