Colloids

The term colloid is often 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 vascular space as long as a colloid.
Hetastarch: Synthetic colloid that works similarly to dextran.

Solution	Components	Indications
Albumin 5%	Human plasma protein.	Rapid volume expansion. Mobilize interstitial edema.
Albumin 25%	Human plasma protein.	Pull interstitial fluid back into circulating volume. Hypoproteinemia.
Plasma	Contains human plasma proteins in NS (Plasmanate and plasma protein fraction).	To increase serum colloid osmotic pressure.
Dextran 40 and 70	Synthetic colloid made of glucose polysaccharides.	Volume expansion. Mobilize interstitial edema. Platelet inhibition.
Hetastarch	Synthetic colloid made from corn (Hespan).	Volume expansion. Mobilize interstitial edema.
