Most coughs and sputum are caused by pneumonia or bronchitis and infectious diseases of the lungs. If the elderly are bedridden for a long time or have serious inflammatory lung infections, it may cause the patient’s sputum to be sticky and not easy to cough up. Treatment methods are as follows: 1. Turn and pat the back of the elderly frequently to promote the discharge of phlegm by patting the back. In addition, because the sputum is sticky, usually make the elderly drink more water to dilute the sputum, so that the sputum can be coughed out easily; 2. Take oral antibiotics or phlegm-cleansing drugs, for example, for patients with serious infection or yellow sputum, antibiotics can be given for treatment. And for patients whose sputum is sticky, they can take oral phlegm-reducing drugs, such as tranylcypromine, etc. If the efficacy is not satisfactory, nebulization treatment can be carried out in a way to dilute the sputum and also reduce the inflammation. 3. Elderly people who suffer from cerebrovascular disease, such as delirium, coma, unconsciousness, dementia, etc., and cough up sputum feebly and with difficulty, need to go to the hospital for aspiration or tracheotomy treatment in time to avoid choking or serious consequences.
