For bronchitis in infants, symptomatic treatment must be actively given in order to achieve the best possible outcome. Treatment can be given according to the pathogens causing bronchitis, such as viruses, bacteria, and mycoplasma. In case of viral infection, give antiviral drugs orally or ribavirin pellets, in case of bacterial infection, give drugs such as cefixime or amoxicillin pellets. In case of mycoplasma infection, give azithromycin or erythromycin for treatment. Infants suffering from bronchitis, sputum will not cough up, and often have the phenomenon of sputum blockage and suffocation, can actively give nebulized inhalation treatment, nebulized inhalation can act directly to the airway, which is conducive to the absorption of sputum and the wetting of sputum, and can significantly relieve the child’s symptoms. Oral cough medicine can also be given to treat the cough, such as pulmonary cough combination or amiloride oral solution. Since the infant’s immune function is relatively poor and the disease takes a longer time to cure, it can be combined with adjuvant therapy, applying treatment similar to transfer factor or pidomod oral solution to improve pediatric immunity, which can effectively shorten the course of the disease.
