If epiglottitis is treated promptly and effectively, it usually does not affect the patient’s life. When the disease progresses rapidly and untimely treatment causes redness and swelling of the epiglottis, blocking the vocal folds, it can cause suffocation and death. Inflammation of the epiglottis is often caused by bacterial or viral infections or trauma to the larynx. The onset of the disease is often acute and explosive, which can be seen in the sudden onset of sore throat, hoarseness, difficulty in swallowing, and even respiratory distress and other manifestations. At this time, it is necessary to keep the airway open to avoid suffocation. The cure rate of the disease is high, and mostly does not affect the survival rate of patients, so there is no question of how long epiglottitis can live. When epiglottitis occurs, it is important to ensure that the airway is open, otherwise the epiglottis may be red and swollen, resulting in airway obstruction, causing asphyxiation and death, and tracheal intubation, tracheotomy and other measures need to be taken to ensure that the airway is open if necessary. Early application of dexamethasone, cefoperazone sodium sulbactam sodium and other drugs to control inflammation, eliminate edema. When the inflammation is effectively controlled, the patient’s survival time will not be affected. It is recommended to consult the doctor as soon as possible for active treatment.
