When patients with cerebral infarction have excessive sputum, it may be because the site of cerebral infarction leads to bulbar paralysis and pharyngeal muscle paralysis, which leads to swallowing difficulty, choking and coughing on drinking and eating, so that the patient’s saliva can’t be swallowed and the sputum can’t be eliminated, so it causes excessive sputum. If it is the acute stage of cerebral infarction, the patient’s body resistance decreases after being bedridden, the food is not good, the nutritional status is poor, and the choking cough or misinhalation may lead to pneumonitis or intrapulmonary infection. If the patient is accompanied by fever, we should actively apply antibiotics for anti-infection treatment, apply sputum chemotherapy drugs or nebulized inhalation, static drip to make sputum diluted and discharged, nursing care must be regularly turned over and knocked on the back to increase the resistance, increase nutrition to help the patient’s sputum diluted and discharged.
