Rewarming following accidental hypothermia in patients with acute subdural hematoma: case report

A 57-year-old man was admitted to the Emergency and Critical Care Department with accidental hypothermia (31.5 °C) after resuscitation from cardiopulmonary arrest (CPA). Brain CT revealed an acute subdural hematoma. Active core rewarming to 33 °C was performed using an intravenous infusion of warm crystalloid. The patient underwent craniotomy soon after admission, with bladder temperature maintained at 33 to 34 °C throughout the surgery. Therapeutic hypothermia (34 °C) was continued for 2 days, followed by gradual rewarming. After rehabilitation, the patient was able to continue daily life with assistance.
