Mannitol promotes diuresis in kidneys by increasing the concentration of filtrates in the kidney and blocking reabsorption of water by kidney tubules.

Besides, how do you give IV mannitol?

One author recommends a test dose of 12.5 to 25 g IV infusion as mannitol 20% to 25% over 3 to 5 minutes. The balance of 50 g IV infusion of 20% mannitol can be administered over 1 hour. Then, 5% continuous IV infusion at a rate sufficient to maintain urine output at 150 to 500 mL/hour.

Does IV mannitol increase blood sugar?

Is mannitol a steroid?

Effects of mannitol and steroid therapy on intracranial volume-pressure relationships in patients. In patients with intracranial hypertension, intravenous mannitol (0.5gm/kg) and intramuscular betamethasone (26 mg) both reduce the volume-pressure response significantly more than they reduce intracranial pressure.

Do If mannitol crystallized?

Mannitol solutions may crystallize when exposed to low temperatures. At higher concentrations, the solutions have a greater tendency to crystallize. Inspect for crystals prior to administration. If crystals are visible, re-dissolve by warming the solution up to 37°C, followed by gentle agitation.

How is mannitol stored?

Cool to body temperature or less before administering. When infusing 25% mannitol concentrations, the administration set should include a filter. Protect from freezing. Store at 20 to 25°C (68 to 77°F).

What should I check before giving mannitol?

Diuresis caused by mannitol administration may exacerbate electrolyte imbalances. Electrolytes should be closely monitored, especially sodium and potassium, during mannitol administration. Urine output should be monitored during mannitol infusion.

Is mannitol a diuretic?


Mannitol is an osmotic diuretic that is metabolically inert in humans and occurs naturally, as a sugar or sugar alcohol, in fruits and vegetables. Mannitol elevates blood plasma osmolality, resulting in enhanced flow of water from tissues, including the brain and cerebrospinal fluid, into interstitial fluid and plasma.

Does mannitol need a filter?
