Solutions
Hypertonic crystalloids
increase osmolality and volume of plasma, draw water away
from cells
Also moves fluids out of tissues and into vasculature
Hypertonic crystalloids examples
3% NaCl
5% NaCl
Hypertonic fluids are used for
Cellular Edema (cerebral edema)
Monitor for overload/HTN
Hypertonic fluids are rarely used d/t
high risk fluids potentially shrinking brain cells
Dextrose solutions
provides calories, reduces catabolism of protein, offers fluid
Glucose + osmotic properties
As dextrose is infused....
The body takes glucose into the cell via insulin
, Leaves the original fluids to have influence on the patient's
fluid/electrolyte status
Monitor for overload/high glucose
