Hyperosmotic/hyperoncotic solutions for resuscitation of hypodynamic shock
First Claim
1. A physiologically acceptable solution for treating hypodynamic circulatory shock in a mammal, said solution containing a crystalloid having a molecular weight less than about 1000 in a concentration of at least about 1800 mOsms and a colloid having a molecular weight in excess of 30,000 in a concentration so as to render said solution hyperoncotic relative to the colloidal osmotic pressure of the normal blood plasma of said mammal.

Abstract
A physiologically acceptable solution which is both hyperosmotic and hyperoncotic with respect to blood plasma and has utility in treating patients experiencing or threatening to experience hypodynamic shock. The physiologically acceptable solution comprises a hyperosmotic concentration of a crystalloid (in excess of about 1800 mOsms) and hyperoncotic concentration of a colloid (in excess of about 30 mm Hg). The physiologically acceptable solution is easily administered by single, rapid infusion of approximately 4 to 5 ml/kg of body weight and results in a rapid and sustained normalization of circulatory function.
