[Anesthesia for bronchoscopy: application of laryngeal mask airway and "minidose midazolam anesthesia"].

Bronchoscopy distresses most of the patients. Therefore, we combines a small dose of midazolam (ca. 2 mg) with laryngeal mask airway. This method of anesthesia has the following features: (1) mild discomfort, (2) day care, (3) putting bronchoscope in or out easily, (4) mild effect on respiration and circulation, and (5) easy respiratory care. But improper cases for this method include non-fasting patients, those at high risk for regurgitation, and those with low pulmonary compliance. This is a very usefull anesthetic method for bronchoscopy.
