Abstract
Aqueous solutions comprising a polysaccharide oncotic agent, a physiologically compatible buffer, a simple hexose sugar, dissolved chloride salts of calcium, sodium and magnesium, and a dissolved organic salt of sodium are disclosed. The solutions are effective substitutes for blood and may be used to preserve the biological integrity of the organs of a mammalian donor organism as shown by superior anatomical integrity of cryopreserved organs and tissues of subjects perfused with the solution. The solutions may be used for maintaining a partially or substantially completely exsanguinated subject at normal temperatures and at temperatures substantially below those normally maintained by a mammal and may be used in conjunction with hypobaric environments to maintain such partially or completed exsanguinated subjects alive without infusing blood back into the subject.
