Volume Expanders

Volume expanders include albumin, dextran, and hetastarch. Often the term colloid is used to refer to all volume expanders.

■ Protein solutions: Albumin, plasma, and commercial plasmas (e.g., Plasmanate).
■ Dextran: Complex, synthetic sugar, metabolized slowly, does not stay in the vascular space as long as a colloid.
■ Hetastarch: Synthetic colloid that works similarly to Dextran.

Volume Expanders (Colloids)

Solution
Components
Indications
Albumin
5% and 25%
Human plasma
protein
■ 5%—To expand
volume and
mobilize interstitial
edema
■ 25%—To treat
hypoproteinemia
Plasma
Plasmanate
Plasma protein
fraction (PPF)
Contains human
plasma proteins
in NS
■ To increase serum
colloid osmotic
pressure
Dextran
40 and 70
Synthetic colloid
made of glucose
polysaccharides
■ To expand volume
■ To mobilize
interstitial edema
Hetastarch
Hespan
Synthetic colloid
made from corn
■ To expand volume
■ To mobilize
interstitial edema

■ Rarely used may be
given emergently to
an exsanguinating
patient
Packed Red

(PRBCs)
No clotting factors
or platelets, 80%
plasma removed
■ To treat acute and
chronic anemia,
blood loss
Platelets
Usually given in
pools of 6–10
units
■ To increase low
platelet counts or
treat coagulopathies
■ One unit will
generally increase
platelet count by
6000 units
Fresh Frozen
Plasma

Plasma and
clotting factors
■ To replace clotting
factors, e.g., after
multiple transfusions
(>6 units PRBCs), or
to reverse the effects
of Coumadin
Cryoprecipitate
Clotting factors
■ To treat hemophilia,
fibrinogen deficiency,
DIC

Autologous Blood Donation/Transfusion
■ A procedure for collecting and storing a Pt’s own blood several weeks before its anticipated need by the Pt.
■ Salvage of blood normally lost during a surgical procedure.

■ Used to prevent the transmission of disease from donor blood. It is not without risk: stored blood may still become contaminated.
