Newborns coughing, snorting and sneezing need to consider neonatal pneumonia, neonatal meconium aspiration syndrome, and dry indoor air. 1. Neonatal pneumonia. Due to intrauterine infection, infection during labor and delivery, contact infection after birth, etc., lung and respiratory tract infections increase secretions, blocking the airway when wheezing and snorting, secretion stimulation, sneezing. 2. Neonatal meconium aspiration syndrome. The lack of oxygen during delivery causes the anal sphincter to relax, expelling meconium, which is inhaled into the respiratory tract, the meconium blocks the airway, secretions increase, and sneezing occurs. 3. Dry indoor air. It may cause cold-like symptoms, which is caused by the dryness of nasal mucosa and increased secretion, pay attention to keep the indoor air moist. Children with uncomfortable symptoms, try to go to the hospital, let the doctor check and diagnose before treatment.
