The main symptom of pediatric bronchitis is cough, which can also be accompanied by coughing up sputum or wheezing and fever. The fever can be high and may be accompanied by febrile convulsions, and smaller babies may have problems such as coughing followed by spitting up. Bronchitis can be caused by pathogens such as bacteria, viruses or mycoplasma, chlamydia, etc. The treatment is different for different pathogenic infections. For viral bronchitis, the treatment is mainly symptomatic, you can give your child expectorant medicine, such as Etanercept or pulmonary cough, and at the same time, use Pramipexole and Ventolin or Corbett to nebulize your baby. For bacterial infections, symptomatic treatment should be accompanied by effective antibiotics, such as cefaclor or cefixime pellets. For mycoplasma or chlamydia, erythromycin or azithromycin should be used.
