The specific treatment for children with bad coughs is as follows: First, you need to take your child to the hospital to identify the cause of the disease and see what pathogenic infections, such as bacterial, viral, and mycoplasma infections, cause further targeted medication. When there is no obvious effect of repeated medication due to long-term infection, it is necessary to take respiratory secretions for drug sensitivity test, and select sensitive drugs for treatment according to the drug sensitivity test in order to play the most fundamental treatment. Second, if the cause is allergic factors need to apply anti-allergic drugs for treatment, such as loratadine, desloratadine, combined with oral montelukast sodium chewable tablets and other common treatment. Third, after detailed examination there is no clear pathogenic bacteria and no allergic factors, foreign body inhalation leading to coughing cannot be ruled out and needs to be removed under bronchoscopy before the child’s coughing problem can be solved. The above is the treatment of the cause, but also to improve the immunity of the child. Many children have a long-term cough caused by a decline in immune function, which can be combined with the application of immunity-boosting drugs, such as transfer factor oral solution or pidomod oral solution, which can be given according to the specific situation of the child.
