Children who cannot spit can be treated with general treatments such as back patting, nebulization therapy and oral phlegm medication. 1. General treatment: If the child can not spit, you can help the child pat the back, from the bottom to the top of the hollow palm patting the back, can effectively promote the discharge of phlegm. You can also drink warm water appropriately to make the throat moist and increase the moisture of the respiratory tract, which can promote the dilution of phlegm and help the liquefaction and absorption of phlegm. Or through swallowing, discharged from the gastrointestinal tract. 2. Nebulization therapy: You can go to the hospital and use sputum-cleansing drugs such as acetylcysteine nebulization therapy as prescribed by the doctor to promote the expulsion of sputum. 3. Oral medication: If your child has a lot of phlegm and can’t spit it out, you can take medication such as aminobromine hydrochloride granules to help dissolve the phlegm and promote phlegm expulsion. Children with phlegm need to be treated in time to avoid aggravating the condition.
