The osmotic diuretic that has been most effective in the reduction of increased ICP is
a. mannitol. c. urea.
b. furosemide (Lasix). d. glycerol.
A
The most widely used osmotic diuretic is mannitol, a large-molecule agent that is retained almost entirely in the extracellular compartment and has little of the rebound effect observed with other osmotic diuretics. Administration of mannitol increases cerebral blood flow and thus induces cerebral vasoconstriction as part of the brain's autoregulatory response to keep blood flow constant.
