Abstract
The laryngo-tracheal analgesia endotracheal tube is a modification of existing endotracheal tubes. It has the addition of an injection port to a lumen in the wall of the tube with exiting holes that correspond to the anatomical position of the epiglottis, larynx and trachea when the tube is correctly placed. The device allows for topical anesthesia to be applied to these pain sensitive areas on ititial placement and while the tube remains in place. The endotracheal tube of the present invention allows a patient to tolerate the presence of an endotracheal tube without discomfort and potentially dangerous reflexes of coughing, gagging, hypertension and tachycardia.
