In 38 patients requiring diagnostic bronchoscopy, three different procedures of anesthesia have been investigated. Of the three, neurolept analgesia combined with topical anesthesia of the airway proved by far the best form. It is followed by psychic indifference without lessening the patient's voluntary control, thus facilitating intricate technical manipulations on the bronchial system. No severe side effects arise when suitable equipment for diagnosing and treating respiratory and cardiovascular depression is available.
