Acute laryngitis generally manifests clinically as hoarseness, more severe dysphonia or complete loss of voice, coughing and dyspnea may lead to asphyxia when it is more severe, and systemic symptoms are generally mild, which may cause infection of adjacent organs and symptoms of upper and lower respiratory tract infection. In terms of treatment, if the vocal cords are obviously congested and swollen, attention should be paid to the administration of glucocorticoids, which can rapidly eliminate mucosal edema in the larynx, reduce the degree of hoarseness, maintain effective respiratory ventilation, and solve the problem of local respiratory distress. Then there should be antiviral and antibiotic treatment. Viral infections can be treated with antiviral drugs, while acute laryngitis secondary to bacterial infections should be treated with antibiotics orally or by intravenous injection. Patients should also be instructed to keep their vocal cords at rest and to keep their voices silent or minimize the number and intensity of vocalizations. The room temperature must be kept constant, the air must be properly circulated, cold and high temperature stimulation should be avoided, and sufficient sleep and rest should be ensured to strengthen the body resistance. Then there can be nebulized inhalation treatment with steroid hormone, which helps to reduce inflammation and swelling, and reduce pain. In terms of prevention, you should actively engage in physical exercise, pay attention to avoiding the stimulation of tobacco, alcohol and spicy food, wear a mask in case of poor air quality, try to avoid possible allergens that may cause laryngitis, and actively treat primary diseases that may cause laryngitis.
