[5-years of experience with tranquilizing-analgesics in laryngo-tracheo-bronchoscopic procedures in newborns and infants ].

Tranquilizing-analgesics (diazepam-ketamine combination anaesthesia) and O2-injector respiration has proved during a period of 5 years in 270 laryngo-tracheo-bronchoscopies of newborns and infants to be an outstandingly well-controllable anaesthesia applicable by the intravenous route which could be applied without danger of depression of breathing or circulation and without injury of the laryngeal protection reflex in this early period of life by means of a balanced cooperation between operator and anaesthesiologist. No serious complications have been observed. The authors' own experiences in handling of the method are described.
