IVF
Anmerkungen:
- Diffusion: solutes move
- Osmosis: Water moves
- Osmolarity
- Hypotonic
Anmerkungen:
- Not for the hypotensive. Treats depleted ICF
- <270 mOsm/L
Anmerkungen:
- Will Lower osmolarity of blood.
Pulls fluids out of ECF n2 ICF
- Any Saline <0.9%. Any
Dextrose < 5%
- Cell Rehydration
- Fluid pulled
from ECF
into ICF
- Extra cellular fluid
Anmerkungen:
- Outside the cells.
Blood, lymph, bone and connective tissue water. Interstital/ transcellular fluids. (CSF,synovial fluid, pleural fluid
- Fluid outside cells
- Intracellular Fluid
- Fluid within cells
- Isotonic
Anmerkungen:
- Wont cause a shift in either fluid compartment.
Treating Hypotension.
- =270-300mOsm/l
- NS 0.9%. D5W. LR
Anmerkungen:
- D5- has calories to decrease catabolism. Once calories are depleted the fluid becomes hypotonic.
Could cause Cerebral edema. Caution with Head injurys
- LR contains Na+,K+,Ca+, Cl-. Ca+ can cause incompatibilities
LR can be helpful in treating metabolic acidosis. Monitor for overtreatment leading to alkolosis
- No fluid shift
- Hypertonic
Anmerkungen:
- >300 mOsm/L
- Dextrose Solutions
> 5%. Saline
solutions >0.9%
Anmerkungen:
- Interstitial edema
- Fluid moves from
ICF into ECF
- Sterile h2o
- Never used as infusion, only dilution
Anmerkungen:
- Could cause cells to explode, too hypotonic
