When patients with cerebral infarction sweat a lot, blood volume should be supplemented in time, and if necessary, volume expansion therapy can be given to prevent hypoperfusion from aggravating the condition of patients with cerebral infarction. Supplementary blood volume and volume expansion therapy are mainly applied to patients with normal cardiac function; if patients have cardiac dysfunction, infusion should generally be slow to prevent aggravation of patients’ cardiac insufficiency. The drugs for supplementing blood volume are generally mainly applied crystalloid fluids, such as saline and sugar saline, and the drugs for volume expansion are mainly 706 plasma substitute. Patients with cerebral infarction may experience profuse sweating due to hyperglycemia, which can cause vegetative nerve dysfunction in diabetic patients, and patients may experience palpitations, chest tightness, and profuse sweating, which can cause electrolyte disorders such as hyponatremia, which may aggravate the patient’s condition, and should be corrected in time.
