Bronchiolitis in babies is an inflammation, which may be caused by infections such as bacteria, viruses, or mycoplasma. The primary treatment is anti-infection, for which antibiotics like oral cephalosporins or penicillin can be chosen for the treatment. Additionally, treatment includes expectorants and cough suppressants, where one or two types of traditional Chinese or Western medicine can be used orally. If the coughing is frequent, nebulized inhalation can be administered to achieve local anti-inflammatory, expectorant, and cough suppressant effects. While treating, it's important to observe the effects and administer intravenous infusions if necessary.
