5
Q

What is the major colloidal particle contributing to colloid osmotic pressure?

A

Albumin (80%)

6
Q

What happens when colloid osmotic pressure is decreased?

A

Fluid accumulates outside of vascular space (Edema/effusion)

Negative acute phase proteins

A

Synthesis is decreased in response to inflammatory cytokines

13

A

SAA

15
Q

Examples of negative acute phase proteins

A

Albumin
Transferrin
Transthyretin
RBP

16
Q

Why is albumin decreased with inflammation?

A

Allows greater amount of amino acids to be used for APP production

17

Mechanisms of hypoproteinemia

A

Decreased production
Increased loss
Sequestration
Dilution

High total protein with low A:G ratio

A

Hyperglobulinemia

Whole blood loss
Severe exudative skin wound

23
Q

What can cause a sequestration of albumin?

A

Body cavity effusion
Vasculopathy
Iatrogenic dilution (IV fluid)

24
Q

What can cause an increased loss of globulins?

A

PLE

Whole blood loss

25
Q

What can cause a decreased production of globulins?

A

Severe, chronic hepatic failure

*Normal for neonate to have decreased globulins (Increase after colostrum)

26
Q

What causes an increase of albumin?

A

Hemoconcentration (dehydration)

27
