MICO-SOLV Pre-Injection Fluid, when used as a first injection, cleanses the arterial, capillary, and venous systems; opens up the circulatory system for the main arterial injection; dilates the capillaries, and loosens clots.  It will not shrink tissue or coagulate albumin.  Because it clears the capillary system of blood, expands the blood vessels, and re-oxygenates the tissues, MICO-SOLV Pre-Injection Fluid should be used when discoloration is extensive.
