Hemispheric body numbness in cerebral infarction is a kind of hemiplegic body sensory disorder caused by cerebral infarction, which is mainly seen in patients with cerebral infarction in the basal ganglia area and large hemispheric infarction. Patients with cerebral infarction in the basal ganglia region mainly present with hemiparesis and hemiplegia, including hemiplegia and hemianesthesia, and patients with left-sided lesions may have speech dysfunction and generally no impairment of consciousness. In the case of large hemispheric infarction, patients can also have disorders of consciousness, such as drowsiness, lethargy and coma, and most patients have cerebral edema and increased intracranial pressure, and patients with severe increased intracranial pressure can cause brain herniation and even death. If a patient has increased intracranial pressure, cranial pressure-lowering therapy should be given promptly. Commonly used cranial pressure-lowering drugs include mannitol, glycerol fructose and tachyphylaxis. If the patient has impaired consciousness, he or she should be given brain-awakening treatment, and the commonly used drugs are mainly brain-awakening drugs.
