Editors Note:

With 2 mEq Being our standard concentration (@ our institutions)–  Here is a break down on one way to work with what’s available:

the 20 mEq/50 ml solution seems to be the best bet:

(0.4 mEq/ml- or 1/5 strength of our current concentration)

So adding 100 cc to a 400 ml NSS bag would give you roughly the 80 mEq/L concentration we use for a 4:1 Blood to Crystalloid (High dose primary KCL) cardioplegia delivery.

And adding 25 cc to a 475 ml NSS bag would give you roughly the 20 mEq / L concentration we use for a 4:1 Blood to Crystalloid (Low dose secondary KCL) cardioplegia delivery.

(I know these are ONLY approximate concentration values)

This is NOT an advertisement for the above products. 

But when discussing it with a good friend and colleague of mine, and in light of the fact that we use the Quest MPS as our cardioplegia delivery system, this seemed to be a reasonable solution. 

My experience with this system ranges 4 years- and it is a solid performer, and effective cooling system.

It allows us to adjust well to the KCL shortage- and eliminates the need for additional heater/cooler hardware additions or heater / cooler modifications.

Any suggestions are welcome ?
