Pediatric acute laryngitis is often caused by viral and bacterial infections, with barking cough, hoarseness, laryngeal ringing, inspiratory dyspnea as the main manifestations, general treatment, glucocorticoids, infection control, symptomatic treatment and tracheal intubation can be taken. 1. General treatment: pay attention to adequate rest, drink plenty of water, keep the airway open, and give oxygen to those who are hypoxic. 2. Glucocorticoid: it has the functions of anti-inflammation and inhibiting metabolic reaction, etc. It can promptly reduce laryngeal edema and relieve laryngeal obstruction. Oral prednisone can be given to those with mild disease, and children with laryngeal obstruction of more than Ⅱ degree should be injected with dexamethasone and hydrocortisone intravenously. Nebulized inhalation of budesonide suspension can promote the subsidence of mucosal edema. 3. Infection control: including antiviral drugs and antibacterial drugs, commonly used drugs are ribavirin, oseltamivir, penicillin, amoxicillin, azithromycin, ceftriaxone, ceftaradin and so on. 4. Symptomatic treatment: dextromethorphan and oral solution of compound Folcodine can be used in case of severe coughing, and sputum that is thick and not easy to be coughed up can be treated with drugs such as oral solution of aminoglutethimide and aminobromine hydrochloride. 5. Tracheal intubation: If there are still signs of severe hypoxia or laryngeal obstruction of more than Ⅲ degree after the above treatment, tracheal intubation, ventilator-assisted ventilation treatment, tracheotomy if necessary. Pediatric acute laryngitis requires prompt medical attention and evaluation by specialist judgment. All of the above drugs should be used under the guidance of a doctor, avoid self-medication.
