Most of the acute catarrhal inflammation of the laryngeal mucosa caused by viral infection. The main manifestations are fever, hoarseness, cough, sore throat and so on. Pediatric acute laryngitis is common in children aged 6 months to 3 years. A part of pediatric acute laryngitis is more serious. At the beginning of hoarseness may not be heavy, early laryngospasm is dominant, “empty” like or “barking” cough, with the aggravation of the disease, hoarseness aggravated, inspiratory wheezing, dyspnea and other symptoms. If the treatment is not timely, there may be pale, cyanosis, confusion, etc., and ultimately death due to respiratory and circulatory failure.
