Pediatric laryngitis is a very acute and dangerous disease, and only a very small number of patients heal themselves. When parents see that their baby is suffering from pediatric laryngitis, they should not expect pediatric laryngitis to heal itself, but should send their baby to the hospital for specialized treatment. 1. Etiology. A baby’s immune system is much weaker than that of an adult. When a cold causes laryngitis, the laryngeal mucosa becomes edematous, which in turn blocks part of the respiratory passages. In severe cases, most of the respiratory passages are blocked. If not rescued in time, the baby’s life will be in danger. 2. Symptoms. The most obvious symptom of pediatric laryngitis is the baby’s “empty, empty” coughing sound. When you hear this sound and your baby has a fever, you should suspect pediatric laryngitis and go to the hospital to confirm your baby’s illness and get prompt treatment. As the baby inhales less oxygen, his face will turn blue and white. 3. Treatment. Use corticosteroids to normalize the edematous mucous membranes and allow the baby to receive oxygen. If the baby is not hyperthermic, cover the baby’s forehead with a towel to lower the baby’s temperature. Let the baby drink plenty of warm water and rest. Parents can take their babies out for exercise to enhance their physical fitness. Keep an eye on the weather and change your baby’s appropriate clothing in time.
