A procedure in which we are able to insert an endotracheal tube into the airway under visual control even in situations where direct laryngoscopy cannot be performed. The fibroscope is pre-loaded with an intubation tube and then serves as a guide. Usually only under local anesthesia in a spontaneously ventilating patient, the device is inserted into the trachea and after it is withdrawn through the ET tube. After verification of the position of the tube (under direct visualization with the fibroscope - the end of the ET tube is above the carina, and detection of etCO2) we can induce the patient into general anaesthesia.
