What happens if you give mannitol too fast?
The obligatory diuretic response following rapid infusion of 25% mannitol (mannitol (mannitol injection) injection) may further aggravate pre-existing hemoconcentration. Excessive loss of water and electrolytes may lead to serious imbalances.
What is mannitol used to treat?
Mannitol has approval for the reduction of intracranial pressure and brain mass. Mannitol is approved to reduce intraocular pressure if this is not achievable by other means. Mannitol can promote diuresis for acute renal failure to prevent or treat the oliguric phase before irreversible damage.
Does mannitol need to be given with whole blood?
Mannitol should not be administered with whole blood. Monitoring When giving mannitol, it is essential to monitor cardiac function as the fluid shifts can precipitate heart failure. Additional electrolytes, including sodium, potassium, and osmolality, all require monitoring.
Why does my mannitol injection solution have crystals?
Manitol Injection solutions may crystalize when exposed to low temperatures. Inspect Mannitol Injection for crystals prior to administration. If crystals are visible, re-dissolve by warming the solution up to 70°C with agitation. Heat solution by using a dry-heat cabinet with overwrap intact.
Should mannitol be given fast?
Administer immediately following insertion of the infusion set. This hypertonic solution should be administered via a large peripheral or preferably a central vein. Rapid infusion in peripheral veins may be harmful. Mannitol solutions may crystallize when exposed to low temperature.
What happens if you give mannitol too fast?
Too rapid infusion of large amounts of mannitol will cause a shift of intracellular water into the extracellular compartment resulting in cellular dehydration and overexpansion of the intravascular space with hyponatremia, congestive heart failure and pulmonary edema.
How fast can mannitol be infused?
The usual dose is 1.5 to 2 g/kg bw (10 to 13 ml/kg bw), infused over 30 to 60 minutes. When used preoperatively, the dose should be administered 1 to 1.5 hours before surgery to obtain the maximum effect. In forced diuresis the dose of mannitol should be adjusted to maintain urinary output of at least 100 ml/hour.
How fast can you bolus mannitol?
Mannitol should be carefully inspected for crystals before it is administered, and it should be administered with an in-line filter, typically 0.22 micron in size. Ideally, the 1g/kg dose of mannitol is administered as a bolus over 30 minutes.
Why IV injection is given slowly?
Medications administered by direct IV route are given very slowly over AT LEAST 1 minute (Perry et al., 2014). Administering a medication intravenously eliminates the process of drug absorption and breakdown by directly depositing it into the blood.

What is the action of mannitol?
Mannitol elevates blood plasma osmolality, resulting in enhanced flow of water from tissues, including the brain and cerebrospinal fluid, into interstitial fluid and plasma. As a result, cerebral edema, elevated intracranial pressure, and cerebrospinal fluid volume and pressure may be reduced.
What should I check before giving mannitol?

Is mannitol hypertonic or hypotonic?
Mannitol, given as a hypertonic solution, is primarily used in the treatment of cerebral edema and glaucoma. Although generally well tolerated, a variety of fluid, electrolyte, and kidney complications can occur if the patient is not carefully monitored.
How does mannitol reduce ICP?
Mannitol exerts its ICP-lowering effects via two mechanisms—an immediate effect because of plasma expansion and a slightly delayed effect related to its osmotic action. The early plasma expansion reduces blood viscosity and this in turn improves regional cerebral microvascular flow and oxygenation.

Until definitive treatment can be arranged, temporary treatments to lower intracranial pressure such as mannitol may be employed.
Why is mannitol given?
Often, the decision to administer mannitol is made due to an acute, severe change in the patient’s neurological status that leads the physician/provider to believe the intracranial pressure is too high. The request is usually for mannitol to be given “STAT.” Variability in dose and administration technique can cause significant delays between the time mannitol is needed and the time it actually gets administered.

How to measure glomerular filtering rate?
Measurement of Glomerular Filtration Rate (GFR): 100 mL of a 20% solution (20 g) should be diluted with 180 mL of sodium chloride injection (normal saline) or 200 mL of a 10% solution (20 g) should be diluted with 80 mL of sodium chloride injection (normal saline). The resulting 280 mL of 7.2% solution is infused at a rate of 20 mL per minute. The urine is collected by catheter for a specific period of time and analyzed for mannitol excreted in mg per minute. A blood sample is drawn at the start and at the end of the time period and the concentration of mannitol determined in mg/mL of plasma. GFR is the number of mL of plasma that must have been filtered to account for the amount excreted per minute in the urine. Normal clearance rates are approximately 125 mL/minute for men; 116 mL/minute for women.
