Ludwig's Angina Emergency Management - Approach, Airway, Imaging * Allow the Ludwig's patient to be in their position of comfort to help maintain a patent airway * These patients will have anatomically challenging airways. If you can, get the patient to the OR for definitive management and let the airway be controlled there with someone present who can do a tracheostomy if necessary. Call your surgeon early. * If immediate control of the airway in necessary, consider awake fiberoptic nasotracheal intubation after thorough topicalization +/- low dose ketamine. A blind nasotracheal approach is a reasonable alernative if you don’t have fiberoptics. Avoid paralytics if the patient is breathing spontaneously and prepare for a cricothyrotomy. * Initiate IV broad spectrum antibiotics including coverage for anaerobes and consider IV dexamethasone as well as nebulized epinephrine * Ludwig's angina is a clinical diagnosis and does not require advanced imaging. Do not delay the patient going to the OR or getting transferred to a hospital with a surgeon for a CT. Remember that the patient has to be comfortable lying flat to get a CT.
