Patients with cerebral infarction can be suffocated by phlegm. If patients with dead cerebral infarction appear to have more and sticky sputum, they should be given nebulized inhalation, intermittent aspiration, and regular turning and patting of the back to facilitate the discharge of sputum and prevent life-threatening effects on the patients. Patients who die of cerebral infarction with more sputum are mainly seen in large hemispheric infarcts and brainstem infarcts. Patients with large hemispheric infarcts and brainstem infarcts have heavier clinical signs and symptoms, and most have impaired consciousness. Patients are usually in a passive flat position and bedridden for long periods of time, which can cause crushing pneumonia with cough and sputum, and also fever. If the patient has inflammation, anti-inflammatory treatment should be given. Patients with brainstem infarction can develop bulbar palsy, which can easily cause aspiration and aspiration pneumonia. In aspiration pneumonia, patients may also develop cough and sputum. In case of aspiration pneumonia, anti-inflammatory treatment should be given promptly.
