What is the differential diagnosis of acute laryngitis in children? Our throat is an important channel for keeping breathing and eating smooth, so suffering from pharyngitis is a painful disease for us. Since the throat of children is narrower, acute laryngitis is very harmful. So what is the differential diagnosis of acute laryngitis in children?

Acute laryngitis in children is the abbreviation of acute laryngitis, trachea and bronchitis. It is called "lock throat wind, acute throat syndrome" in traditional Chinese medicine. It is a common acute and severe disease in infants and young children during sudden changes in temperature or cold seasons. It is mainly characterized by hoarseness, cough like dog barking, accompanied by varying degrees of inspiratory wheezing, and worsening at night. It is prone to complications of laryngeal obstruction, pneumonia, and heart failure, and severe cases can be life-threatening.

Diagnosis of acute laryngitis in children

1. Tracheobronchial foreign bodies

The onset is sudden, and there is often a history of foreign body inhalation. Children have symptoms such as severe coughing and dyspnea. Chest auscultation, X-ray examination and bronchoscopy can differentiate the two diseases.

2. Laryngeal diphtheria

Laryngeal diphtheria has a slow onset, with low fever and obvious systemic poisoning symptoms, pale complexion, listlessness, thin and rapid pulse, and a grayish-white pseudomembrane often in the pharynx. Examination of secretions can reveal diphtheria bacteria.

3. Laryngeal spasm

It is common in younger infants, with an acute onset and inspiratory laryngeal wheezing with a sharp and thin tone. The attack is short-lived and the symptoms may disappear suddenly without hoarseness.

4. Laryngoscopy examination shows 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 accompanied by mucopurulent secretions, and the subglottic mucosa is swollen and protrudes to the middle to form a narrow cavity.

5. Based on its unique symptoms such as hoarseness, laryngeal wheezing, "empty" cough, and inspiratory dyspnea, the diagnosis is usually not difficult. Laryngoscopy can be performed if necessary.

Acute laryngitis is often secondary to acute rhinitis and pharyngitis. When children suffer from this disease, they should be actively treated to prevent the progression of inflammation. Acute laryngitis is easily induced when children are malnourished, have low resistance, have allergic constitutions, and have chronic upper respiratory tract diseases. The above causes or inducements should be actively treated or corrected.
