Laryngitis is an acute inflammation of the laryngeal mucosa, mainly in the vocal fold area, which develops in winter and spring, and is common in infants and children. Because of the small laryngeal cavity of children, the laryngeal mucosa is loose and swollen, which can easily lead to obstruction of the vocal cords, and the poor cough reflex of children, the tracheal and laryngeal secretions are not easily discharged, which can easily cause serious laryngeal obstruction; in addition to laryngeal dumbness, there can be obvious breath-holding, breathing difficulties, throat like something stuck, coughing sound like barking; if timely and effective treatment is not taken, the condition can be progressively aggravated, endangering the health and even the life of the child. It is a pediatric emergency. The key to the treatment of acute laryngitis is to release the laryngeal obstruction as soon as possible, early use of adequate amounts of glucocorticoids to promote the decreasing of laryngeal edema, nebulized inhalation of glucocorticoids is the best method, if you have a nebulizer at home, to wait for the ambulance or cab, the first time nebulized 1-2 times, and then rushed to the hospital, can slow down the progress of laryngeal obstruction; at the same time can be given antibiotics to control infection, antispasmodic, phlegm treatment, etc. To minimize the baby crying, shouting, etc., to maintain a quiet state, so as to facilitate the recovery as soon as possible, and more closely observe the child’s breathing. In addition to acute laryngitis resulting in mute throat, attention should also be paid to exclude laryngeal (especially vocal cord) abnormalities, such as vocal cord nodules; congenital laryngeal softening disease and other congenital diseases of the larynx, through laryngoscopy can help differential diagnosis.
