FIG. 5.

A 24-year-old man was admitted to our hospital after a severe traumatic brain injury with a prehospital Glasgow Coma Score of 6. The computed tomography (CT) scan was classified as a diffuse brain injury type II of the Marshall's classification. In the three CT scan slices shown here (A, B, and C), a small right frontal contusion together with a small subdural hematoma and subarachnoid blood in the interpeduncular cistern are observed. The white circle in (C) indicates the MD probe that was located at a distance of 41 mm from the subdural hematoma. The table summarizes the ionic concentration in the plasma, the dialysate, and the estimated concentration in the brain calculated according the equations described in the text.
