Acute epiglottitis is an acute inflammatory lesion of the mucosa of the epiglottis, which often starts quickly because the tissue around the epiglottis is loose, and once acute inflammation occurs, the epiglottis will swell up to 4-5 times its normal size, blocking the airway and easily causing severe respiratory distress and even death by asphyxiation in time for resuscitation. Acute epiglottitis diagnosis and treatment A. The etiology of acute epiglottitis 1, infection is the most common cause of this disease, the causative agents are B. influenzae, Staphylococcus, Streptococcus, D. pneumoniae, Neisseria pupillarum, diphtheria-like bacilli, etc., can also be mixed with viral infections. 2, allergic reactions systemic allergic reactions can also cause a high degree of edema in the epiglottis and aryepiglottic folds, secondary infection and morbidity. 3, trauma Foreign body trauma, irritating harmful gas, irritating food, radiation damage, etc. can cause inflammatory lesions of the eccrine mucosa. 4.Acute inflammation of adjacent organs such as acute tonsillitis, pharyngitis, oropharyngitis, rhinitis, etc. spread and invade the epiglottis. It can also be secondary to acute infectious diseases. Clinical manifestations of acute epiglottitis 1, the onset of acute epiglottitis, mostly fever, chills, headache, general discomfort. 2, pharyngeal pain is severe, aggravated when swallowing, so there is often saliva spillage. 3, due to the swelling of the epiglottis, so that the language is slurred, as if there is something in the mouth. 4. In severe cases, there can be a sense of laryngeal obstruction, breathing difficulties, and even death by asphyxiation. 5. Redness and swelling of the epiglottis can be seen under indirect laryngoscopy, especially on the lingual surface, which can be spherical in heavy cases. Third, the treatment of acute epiglottitis 1, timely and adequate application of broad-spectrum antibiotics. 2, if the epiglottis swelling is obvious, accompanied by respiratory distress should be added at the same time with hormone intravenous drip, to reduce the epiglottis edema. For those with obvious laryngeal obstruction symptoms, tracheotomy should be made in time to avoid asphyxia. 3. For those with abscess formation, laryngoscopic incision can be made to drain the pus. 4. Local steroid hormone nebulizer inhalation should be given to promote the inflammation to subside.
