It is certainly complex, but does away with the disadvantage of prolonged storage.

Ten days later the patient is operated upon, with two units of blood available which are less than ten days old (Fig.

They are used alone or with 4 % albumin. Starch derivatives (hydroxy-ethyl starches) These are recently developed molecules, not available in France. With a molecular weight of 40,000 to 200,000, their half life is 6 to 8 h. Their effect on blood flow is unknown, but they are good plasma expanders. Plasma derivatives Human albumin, of which the half life is long (from 4 to 5 days), is 30 Hemodilution particularly valuable for use after delayed accidental hypovolemia, with the further advantage that rouleaux formation is inhibited, leading to a marked reduction in blood viscosity with very little erythrocyte deformity.
