Pediatric acute laryngitis has a rapid onset and changes rapidly, and should be given timely treatment, and can generally be cured in 7-10 days; if the condition is not controlled, it can prolong the recovery time. The first 1-2 days of acute laryngitis in children can progress rapidly from mild cough to hoarseness, and even difficulty in speaking and barking cough, which can lead to respiratory distress in severe cases. If not given timely and effective treatment, laryngeal obstruction and even death may occur. If glucocorticoid nebulization, intravenous medication, and antibiotics are given, the progression of the disease can usually be controlled quickly and can be cured in 7-10 days. If the progression of the disease leads to respiratory distress or even requires tracheotomy to improve ventilation, the recovery time will be further prolonged. If you find that your child has a cough or hoarseness, you should go to the pediatric department of a hospital or an emergency room in a timely manner, so that your child’s condition can be clarified by a professional doctor and then treated in a timely manner to avoid delays.
