Hi littlebear23, I know that high potassium levels can kill people. But i also now that Acute increase in osmolality, such as hyperglycemia, causes potassium to exit cells and then increases the level of potassium in the blood stream. So i was thinking along those lines that if you treat the hyperglycemia first it will reduce the levels of potassium being released from the cells. Also i guess i should of said that his potassium level is only 6mmol/l and i believe this is only a slight increase and thats why i thought that i would treat the hyperglycemia first. Thanks for your input and i will do some more research as i know i need to. And thanks to david nelson as well for your input i will look into that as well.
