What are the methods for diagnosing acute laryngitis in children? Acute laryngitis in children is one of the acute respiratory emergencies in children. It is an acute diffuse inflammation of the laryngeal mucosa. It is more common in children aged 1-3 years old and is prone to occur in winter and spring. It is serious and must be actively diagnosed and treated once it is found. So, what are the methods for diagnosing acute laryngitis in children?

The diagnosis can be made by the child's symptoms and signs:

The onset is relatively acute, and most patients have fever, hoarseness, and cough. Hoarseness is not serious at first, and there is wheezing when crying. Then the inflammation invades the subglottic area, and the cough becomes "empty" and "empty", and the night sound symptoms worsen. In more serious cases, inspiratory laryngeal wheezing, dyspnea during inspiration, inhalation of suprasternal fossa, supraclavicular fossa, intercostal and upper abdominal soft tissues, and other symptoms of laryngeal obstruction may occur. Severely ill children have cyanosis or pallor around the mouth and nose, cyanosis of fingers and toes, and varying degrees of irritability and sweating. If not treated in time, the face will turn pale, breathing will be weak, circulation and respiratory failure, coma, convulsions, and even death.

Diagnostic tests:

Laryngoscopy can reveal that the laryngeal mucosa is congested and swollen, the vocal cords are also congested and red, with dilated blood vessels on them, the glottis is often covered with mucopurulent secretions, and the subglottic mucosa is swollen and protrudes toward the middle to form a narrow cavity. The diagnosis is usually easy based on its unique symptoms such as hoarseness, laryngeal wheezing, "empty" and "empty" coughing, and inspiratory dyspnea. Laryngoscopy can be performed when necessary.

The key to the treatment of acute laryngitis in children is to relieve laryngeal obstruction as soon as possible, use effective and sufficient antibiotics to control infection as early as possible, give glucocorticoids to promote the disappearance of laryngeal edema, strengthen oxygenation, antispasmodics, expectorants and other treatments, and closely observe the child's breathing. After active treatment, if the symptoms do not improve significantly or further worsen, severe breathing difficulties may occur, and even cause respiratory and circulatory failure and death.
