Abstract:

Objective  To improve the diagnosis and treatment of tracheobronchial foreign bodies and lower the complication rate by comparing the applications of rod-lens and conventional bronchoscopy in tracheobronchial foreign body extraction. Methods  The diagnosis, anaesthesia methods,operation methods and therapeutic effect of 206 cases of foreign bodies were reviewed. Rod-lens coupled with grasping forceps sheaths tracheobronchial foreign body extraction was compared with conventional bronchoscopic foreign body extraction. Results  Patients  extracted by rod-lens coupled with grasping forceps were all primarily successful. 10 patients extracted by conventional bronchoscope were operated on for the second time. In bronchoscopic foreign body extraction, 8 cases of laryngospasm and 12 cases of bronchiospasm were found  during operation, and there were one case of mediastinal emphysema, 2 cases of pneumothorax, 4 cases of subcutaneous emphysema, 2 cases of heart failure and 5 tracheotomy after operation. No death and serious complication occurred. Conclusions  Rod-lens coupled with grasping forceps sheaths for extraction of tracheobronchial foreign bodies has its own advantanges of visualization and amplification, avoiding the blindness of conventional bronchoscopic foreign body extraction and making the surgery safer and more successful.
