During the 7-day dangerous period of cerebral infarction, the following points should be noted when accompanying the patient: 1. Observe the changes of the patient’s state of mind, pupils and vital signs. Patients are prone to cerebral edema, elevated blood pressure, shortness of breath and other complications during this time. Observe whether the patient’s mental state is clear, whether the bilateral pupils are equal in size and roundness, whether the light reflex is sensitive, and whether there are obvious abnormal fluctuations in blood pressure and respiratory rate. If there are obvious abnormalities, we should be alert to cerebral edema and cranial hypertension, and should elevate the head of the bed by 30° to reduce the venous return of the brain and reduce the incidence of cerebral edema. At the same time, dehydration, cranial pressure reduction, oxygen therapy, stabilization of blood pressure should be given urgently, and if necessary, decompression surgery should be performed to remove the bone flap, otherwise it will be a serious threat to the patient’s life safety.2. Patients should be encouraged to cough and expectorate more, and they should be turned over and patted on their backs in 2-3 hours to promote the expectoration of sputum and to prevent lung infections.3. In the acute stage, patients often have choking and coughing on drinking water and they should formulate a feeding program based on the pudding scores. Eat less and more meals, with rice paste, noodles as the main, reduce the amount of one-time water intake. When feeding, the patient should be allowed to sit up to avoid reflux and aspiration.4. Help the patient to move the muscles and joints of the lower limbs to avoid the formation of deep vein thrombosis of the lower limbs.
