Q

Hypovolemia in TBI patient is dangerous. What fluids would you use?

A

AVOID HYPOTONIC SOLUTIONS & solutions with sugar, rather use HypERtonic solutions -> Lactated Ringers & Normal Saline 3%-23.4%

Monitor sodium levels. Hyponatremia can cause brain swelling
Careful not to fluid overload and cause pulmonary edema

Q

Mannitol (Osmitrol) is contraindicated in what patients? Why?

A

TBI patient who are Hypotensive &/or Hypovolemic. Because it is a potent osmotic diuretic and can worsen hypotension and cerebral ischemia

Q

Treatment for a euvolemic patient w/ TBI in observation who develops an acute onset of a dilated pupil, has hemiparesis, or loses consciousness? How is it given

A

Mannitol (Osmitrol)
In this case, give a bolus 1g/kg rapidly over 5 minutes & immediately transfer to CT scanner or operating room if a causative surgical lesion is already identified

Q

When using Manitol for treatment of elevated ICP. What should be used for monitoring? What is a contraindication? Goals of treatment?

A

ICP Monitor, unless evidence of herniation. Keep Sasm < 320mOsm. maintain euvolemia, and use bolus rather than continuous drip

Sasm (serum osmolality)
