After heart attack and cerebral infarction, heart rate, blood pressure is still normal, has been drowsy may be due to insufficient blood supply to the heart and brain, large cerebral infarction or brain stem infarction, arterial blood supply area of local necrosis of the brain tissue, the causes of different specific treatment programs are different. 1. Insufficient blood supply to the heart and brain: Insufficient blood supply to the brain can cause drowsiness. If the patients injected with anesthesia drugs are more sensitive to the drugs, there will be a period of lethargy, which can be restored to wakefulness in general. 2. Massive cerebral infarction or brainstem infarction: the patient should be placed in supine position with head tilted to the side to prevent tongue falling back or secretion blocking the airway causing asphyxiation. Nursing staff should turn over and pat the patient’s back regularly to avoid decubitus ulcers and intrapulmonary infections. Give bedside rehabilitation therapy to prepare for the patient’s wakefulness and rehabilitation, and avoid double lower limb thrombosis. Can be given to promote wakefulness of drugs such as awake brain Jing. 3. Necrosis of local brain tissue in arterial blood-supplying area: patients often have symptoms of neurological deficits such as hemiparesis and hemianesthesia. Low molecular heparin and other anticoagulants can be injected to stabilize the progressive development of the disease. Because the specific physical status of each patient is different, the treatment effect and the choice of program are not the same, it is recommended to go to a higher level hospital for further consultation.
