For laryngitis, it is best to undergo infusion therapy. Acute laryngitis is an otolaryngology emergency, commonly occurring in infants and toddlers because their pharyngeal mucosa is relatively loose. Once infected by bacteria or viruses, it can cause sudden high fever with temperatures above 38℃ (100.4°F), as well as hoarseness and breathing difficulties. In severe cases, it may lead to asphyxiation or even death. Examination with an electronic laryngoscope can reveal significant hyperemia and edema in the pharyngeal mucosa, especially severe around the bilateral vocal cord arytenoid areas, leading to incomplete glottis closure. Under such circumstances, it is best to use antibiotics, such as cephalosporin antibiotics, and the patient should undergo infusion therapy. Additionally, it is advisable to use corticosteroids to reduce local mucosal congestion and edema. A light diet should be maintained during treatment, closely monitoring the patient’s breathing. If breathing difficulties arise, a tracheotomy may be necessary.
