Whether a patient with cerebral infarction needs to be treated in ICU in the acute stage depends on the patient’s symptoms, neurological signs, vital signs, and combined with the imaging performance. If the patient shows loss of consciousness, dilated or severely reduced pupils, unstable vital signs, and imaging suggests large cerebral infarction in the acute stage, it is generally necessary to consider going to ICU for intensive treatment. If the patient is conscious, has stable vital signs, no symptoms of cranial hypertension, and imaging does not suggest large cerebral infarction, treatment in a general ward is sufficient. Of course, 30% of patients with cerebral infarction will progress further during the acute phase, and patients with unstable vital signs will also need to be treated in ICU, as well as serious complications with severe pulmonary infections and severe electrolyte disturbances that affect the patient’s breathing and confusion, then they will also need to be transferred to ICU.
