Common causes and treatment 1, infant asthma: early symptoms of upper respiratory tract infection mostly appear, such as fever, runny nose, sneezing, sore throat and cough, followed by wheezing with thicker and shorter wheezing sounds and lower tone, often accompanied by vesicular sounds. It is recommended to use medications as prescribed by the doctor for control, such as inhalation with budesonide suspension for nebulized inhalation; 2. Bronchitis: wheezing sounds appear in the lungs, mostly caused by bronchitis, which can be secondary to respiratory tract infection, with a more rapid onset, 1-2 days after the cough aggravates, with dyspnea, wheezing, blue lips, wheezing sounds, i.e. similar to “goose goose “sound. Amoxicillin anti-infection can be given as prescribed by the doctor, or β-2 agonist can be applied to treat tracheospasm; 3. Pediatric laryngeal chondrosis: due to immaturity and softening of laryngeal cartilage, resulting in collapse of soft tissue in the upper part of the vocal tract during inspiration, causing airway obstruction and wheezing sound. Most children can heal spontaneously, but surgery is feasible if necessary; 4. Laryngeal edema: infiltration of tissue fluid under the mucosa of the larynx caused by various inflammatory diseases, resulting in laryngeal wheezing and dyspnea, which can be accompanied by fever and sore throat. Based on daily care, keep the larynx moist, try to let the child breathe through the nose, etc. If there is no relief for a long period of time, it is recommended to consult a doctor to find out the cause and avoid delaying the treatment.
