Management of Reye's syndrome. A rational approach to a complex problem.

Five patients suffering from progressive Reye's syndrome were aggressively treated in our ICU. Our protocol consisted of endotracheal intubation, curarization, mechanical ventilation, hypothermia to 31 degrees C, and fluid restriction. Intracranial pressure (ICP) was monitored and remained below 10-20 torr in all patients except one in whom ICP rose only once (for a few minutes) to 27 torr. Pulmonary artery wedge pressure was monitored in 4 patients and was maintained at 4-5 torr. Duration of active intervention as outlined above was 3-4 days. All 5 patients started with clinical stage IV and EEG grade IV or worse. Four patients had complete recovery and one died. In this group of patients, high ICP was not a feature of the disease. We recommend that use of mannitol for active dehydration be reserved for cases with proven rise in ICP, in which case hemodynamics should be carefully monitored.
