What are isotonic crystalloids?
|
-Similar osmotic pressure to the fluid it is being compared to
- Distributes evenly into extravascular space (IV) - Only 25% of crystalloid fluid administered in thee intravascular space of ECF after 1 hour - May cause peripheral edema |

|
Negative
|
|
What is an example of a synthetic colloid?

Albumin (produced in liver)
|
|
What are dextrans?
|
- Polysaccharides
- Have high and low molecular weight forms - Metabolized mainly by the kidneys and the remainder by the liver |
|
What are some pros of synthetic colloids?
|
- Safe as small boluses to correct hypovolemia
- Fewer instances of peripheral edema - Less need for positive inotrophs (force of contractions) for BP support - Significantly decreased volume of crystalloids needed when used concurrently |
|
What are some cons of synthetic colloids?
|
- Anaphylaxsis (small percentage)
- May falsely elevate coagulation profiles |
|

|
|
Do you have to cross-match with oxyglobin?
|
No
|
|
What can oxyglobin cause?
|
- Transient yellowing of MM, sclera, skin and urine (not due to liver failure)
|
|
What is the dose for human albumin?
|
0.3mL/kg/hr over 4-24 hours
|
|
What dose do you not want to exceed with human albumin?
|
2g/kg/day
|
|
Does third-space losses change a patients body weight?
|
No, because the third-space is still in the body
|
