[General anaesthesia in microlaryngeal surgery by injection-technique with a modified Carden tube (author's transl)].

A method of general anaesthesia and pulmonary ventilation with automatic intermittent positive pressure for endoscopic laryngeal surgery is described. We have used a technique with a modified Carden tube which gives more freedom to the otolaryngologist. Arterial blood gas studies performed on 10 patients indicated adequacy of ventilation throughout and following the procedure. The special features of this technique are mentioned.
