ABSTRACT
To evaluate the clinical therapeutic effect of limited bronchus granuloma caused by foreign body with medication in trachea, 6F tube was put in sick trachea under fibrobronchoscopy in 26 patients with bronchus granuloma due to foreign body, and 5ml of 2% lidocaine + 10ml of sterile Saline + 5mg dexamethasone +antibiotics (Amikacin0 2g or ceftriazone1 0g) were injected into sick trachea through 6F tube twice a day. 25 were cured, the cure rate was 96 2%,and the other one had to be operated; the course was 6～15d. Other 29 patients were treated with routine antibiotics intravenation+aerosol inhalation or medication in trachea under fibrobronchoscopy every other day, and 24 were cured, the cure rate was 82 8%; the other 5 had to be operated, the course was 6～32d. It is suggested that the former method has good effect in local anti inflammation, and can decrease the intravenous antibiotics dosage and side effect.
