[Successful use of mild hypothermia therapy in a patient with severe clinical Reye syndrome].
This report describes a case of two-yr-old female with severe clinical Reye syndrome (Stage III and over), who was treated with not only conventional therapies but also mild hypothermia therapy. She presented acute episodes of tonic convulsion, hepatic dysfunction and intracranial hypertension. The first treatment consisted of the administration of anticonvulsant and mannitol, which were not effective to control intracranial pressure. Therefore, we induced mild hypothermia to rectal temperature of 33-34 degrees C for ten days to control intracranial hypertension as well as barbiturate therapy and hyperventilation under mechanical ventilation. Although she had hypokalemia, atelectasis of the right upper lung lobe and thrombocytopenia as the side effects during this therapy, we effectively controlled ICP. Glucose fluid therapy is recommended for Reye syndrome. We especially should pay attention to hypokalemia because of hyperventilation, absorption of potassium with insulin and transudation of potassium from the intestine. We determined the initiation and weaning of mild hypothermia therapy by findings of MRI as well as intracranial pressure. MRI findings will contribute to the determination of initiation and weaning of mild hypothermia therapy. Mild hypothermia therapy should be considered in patients with severe clinical Reye syndrome if conventional supportive therapies are not effective.
