Abstract

Colloids are large molecular weight (nominally MW > 30,000), homogenous, non-crystalline substances that largely remain in the intravascular compartment. Colloids are important in capillary fluid dynamics because they are the only constituents which are effective at exerting an osmotic force across the wall of the capillaries. In normal plasma, the plasma proteins are the major colloids present. Albumin solutions are available for use as colloids. In addition, various other solutions containing artificial colloids are available. Most colloid solutions contain colloid molecules dissolved in isotonic saline. The general characteristics of colloids, the types of colloidal plasma substitutes (except hydroxyethyl starch), the indications, contraindications, advantages, disadvantages and the dosage of each of them have been described here.
