Acute laryngitis is an acute diffuse inflammation of the mucous membrane of the larynx, which is prone to laryngeal obstruction, especially at night, so night care is especially important. What should be paid attention to in night care when acute laryngitis occurs in babies? It is recommended to sleep in a semi-recumbent position at night to keep the airway open, because the anatomical structure of the baby’s respiratory system is characterized by a narrow laryngeal cavity and a narrow vocal folds, and inspiratory dyspnea can occur with mild inflammation, while adopting a semi-recumbent position can effectively prevent the risk of aspiration. Moreover, the living room should be ventilated by opening windows, keeping quiet as much as possible and minimizing noise, so as not to induce the baby to be irritable and dangerous. Parents should pay special attention to observe the baby’s color, breathing and heart rate, once abnormalities occur, go to the hospital in time to seek medical help.
