Why the high potassium chloride in cardioplegia doesnt affect the vein grafts in CABG while it does when given through peripheral veins?

10 May 2017 0 9K Report

KCL is very irritant when given through peripheral veins. It can cause thrombophlebitis. But we give high concentrations of KCL through veins as cardioplegia during CABG ie through vein grafts. Why it doesnt affect veins here?
