Cerebral infarction may be complicated by severe pneumonia. According to the data of China Stroke Report 2019, the first in-hospital complication of cerebral infarction hospitalized patients is pneumonia/pulmonary infection, with a proportion of 10.1%. 1. Patients with cerebral infarction are often accompanied by confusion or even fainting during the acute stage of seizure, and at this time, it is very easy for aspiration to occur, such as saliva and vomitus mistakenly entering the airway, which can lead to pneumonia. 2. Patients with cerebral infarction in the brainstem and swallowing-related functional areas often suffer from swallowing dysfunction, which makes them prone to choking and coughing when drinking or eating, leading to aspiration pneumonia. 3. Severe pneumonia is the most common cause of death in bedridden patients with cerebral infarction: 75% of cerebral infarction patients in China are combined with hemiplegia, and 25-50% of cerebral infarction patients are partially or completely dependent. Long-term bed-ridden patients are prone to choking and coughing, causing lung infections, and sputum cannot be discharged, which can easily develop into severe pneumonia. 4. For bedridden patients with cerebral infarction, caregivers must turn over, pat the back and suction more often to avoid aspiration pneumonia caused by bedridden patients and avoid pressure sores caused by patients in one position for too long. For patients with cerebral infarction who have swallowing dysfunction, when feeding water and food, the patient must be allowed to sit up or shake the bed, feed slowly, and if necessary, insert a nasal feeding tube to reduce the occurrence of aspiration pneumonia. It is recommended that patients with cerebral infarction should consult a doctor if they have cough, sputum, or fever, and receive treatment as soon as possible to avoid the occurrence of severe pneumonia.
