Pharyngolaryngeal epiglottitis, acute epiglottitis, can be caused by bacterial and viral infections, allergen exposure, physical and chemical irritation, and trauma, among other etiologic factors. The disease often develops at night, and the history of the disease usually does not exceed 6-12 hours. Early in the onset of the disease, most of the patients will suddenly wake up in their sleep due to pain in the throat or dyspnea, which is aggravated by swallowing, and there may be outflow of saliva. Some patients have normal pronunciation but their speech is slurred. In allergy-induced cases, early symptoms such as obvious laryngopharyngeal blockage, unclear speech, and sudden choking can easily occur when coughing or deep breathing. Once acute epiglottitis occurs, it is necessary to follow the doctor’s advice and timely treatment, so as to avoid the deterioration of the condition and injury to life.
