Pearls & Oy-sters: The effects of renal replacement therapy on cerebral autoregulation

PEARLS  Hemodialysis (HD) has been associated with increases in intracranial pressure (ICP). Osmotic shifts occurring during HD are thought to be associated with the development of this phenomenon.  In comatose patients with acute brain injury, an elevation of ICP during HD may be associated with worse cerebral autoregulation. Continuous veno-venous hemofiltration (CVVH) may be a safer alternative in these patients. OYSTER  HD may increase ICP; therefore, caution should be exercised when HD is needed in patients with acute brain injury. CASE REPORT A 59-year-old man with hyperten
