A child’s recurrent cough brings endless worries to parents. There are very many medications for coughs, but many of them are not effective. A child’s repeated coughing seriously affects the rest of the child and the parents. Coughing is a symptom and a protective action. By coughing, you can get rid of phlegm and other garbage. However, if the cough is more severe and seriously affects life, appropriate treatment needs to be given. Cough treatment includes expectorant and phlegm reduction and reduction of respiratory mucous membrane edema. First of all, the cause of the cough should be analyzed and the treatment should be directed to the cause in order to receive good results. 1. If it is inflammation of the tracheobronchial tubes, the blood count and C-reactive protein should be checked. If the blood picture is high, treatment with anti-inflammatory drugs to relieve cough and phlegm is needed. 2. If the chronic cough is caused by sinusitis, chronic rhinitis, or pharyngitis, the ENT doctor should be called to give the appropriate treatment. The treatment of this cough should focus on the protection of the respiratory mucous membrane cilia recovery, too much anti-infective cough treatment is often ineffective. 3. Another special case is allergic cough, which also has a high rate of misdiagnosis. In this case, it is necessary to identify the allergens, keep away from them, and give the appropriate medication. The effect of cough suppression and phlegm reduction alone is often not good, so ketone body powder or albuterol can be given as treatment. If the cause of the cough can be correctly determined, and with proper rest, drinking more water, and keeping the room air moist, along with proper dietary therapy is often more effective.
