Complications resulting from or coincident with tracheotomy are unusual. Emphysema of the subcutaneous tissues may occur, and possibly air may extend into the mediastinum and rarely into the pleural cavity. Suturing of the tracheotomy wound really is of no value and may cause or aggravate an emphysematous condition.
Kahler,1 in his study of the literature, found only two cases of perforating injury resulting from bronchoscopy. Both accidents occurred in small children. In one case there was collapse of the lung due to an injury to the pleura by the bronchoscope. In the second case there was emphysema of the body from head to foot resulting from the injection of silver nitrate through the bronchoscope; the child recovered in a few days.
Imperatori2 reported a case of pneumothorax complicating bronchoscopy and later did experimental work on animals showing the effect of puncture of the bronchus, mediastinum and pleural cavity by the
