What are the symptoms of cerebral edema after craniotomy?

After craniotomy, cerebral edema may cause symptoms such as headache, nausea, and vomiting. If brain swelling damages local motor nerves or language areas, it can lead to functional disturbances in the limbs, and even cause severe symptoms such as seizures or paralysis. Patients can use medications to alleviate edema, including hyperosmolar dehydrating agents, hypertonic saline, albumin, and diuretics. If brain disorders occur, craniotomy must be performed promptly to prevent cerebral edema, as edema poses significant risks and can endanger the patient's life.
