Pediatric acute laryngitis is caused by viral or bacterial infections, mostly occurring at night, mainly with sudden onset of hollow-like cough, hoarseness, inspiratory dyspnea, and fever. Its treatment includes the following two main aspects: 1. It is necessary to control the infection promptly and effectively, and give the application of an adequate amount of antibiotics. If the child does not have a history of drug allergy, penicillin or cephalosporins and macrolides can be given, and children with severe laryngitis can be given a combination of antibiotics. 2. Glucocorticoids are mainly applied, which have anti-inflammatory effects and can reduce the child’s laryngeal edema. For children with mild disease, oral prednisone can be chosen. However, children with laryngeal obstruction of degree II or above should be given intravenous dexamethasone or methylprednisolone and other drugs in a timely manner. For children with significant hypoxia, oxygen and sedation treatment can be given. If the child still has significant hypoxia after treatment, or if the child has laryngeal obstruction of degree III or higher, emergency treatment by tracheotomy should be promptly requested from a quintuple surgeon.
