Acute epiglottitis is an acute inflammatory lesion of the mucosa of the epiglottis that often leads to abscess formation when not treated properly and can be seen in both children and adults. Acute epiglottitis usually occurs in children and older frail patients. Because of the loose tissue space around the epiglottis, once inflammation occurs, it is easy to develop acute and severe edema, and the onset of the disease is rapid, causing respiratory distress. Death is caused by asphyxia in time for resuscitation. Clinical manifestations: (1) rapid onset, mostly fever, chills, headache, general malaise, and in severe cases, respiratory distress. (2) Severe laryngeal pain, aggravated when swallowing, so there is often saliva spillage. (3) Swelling of the epiglottis may cause slurred speech, as if there is something in the mouth. Examination: Indirect laryngoscopy shows redness and swelling of the epiglottis, especially on the lingual surface, which can be spherical in heavy cases, and if an abscess is formed, yellow-white pus spots can be seen on the lingual surface of the epiglottis. Treatment: (1) High-dose broad-spectrum antibiotics (2) If the swelling is severe and accompanied by respiratory distress, hormones should be added intravenously at the same time to reduce epiglottis edema. For those with obvious symptoms of laryngeal obstruction, tracheotomy should be made in time to avoid asphyxia. (3) For those with abscess formation, laryngoscopic incision and drainage of pus can be performed. (4) Local antibiotics plus hormone nebulization inhalation should be given to promote the inflammation to subside.
