Hi Kimmie,
I have been an ICU nurse for 4 years in the capital district. I have never push insulin during a Code. I am not sure what she may be talking about. It may be a strech but is she talking about treating a patient with high K level during a code? I really have no idea. I am ACLS certified and have not heard of this. It sounds like she is trying to treat a "cause"..aka the high potassium level. Please feel free to contact me via private message if you have questions.

Check out this link. This involves giving a combination of glucose and insulin to rats in asphyxial cardiac arrest. Apparently the combination (but neither glucose nor insulin alone) improved neuro outcomes. Couldn't find any human studies or anything on the specific mechanism.

Rationale for IV glucose/insulin: Glucose and insulin shifts potassium from the extracellular fluids back into the cells. This may reverse severe symptoms long enough to allow correction of the etiology of the hyperkalemia.
Excellent article from eMedicine:
I recently heard a researcher at my school discuss the benefits of infusing a solution containing glucose, insulin, and potassium. Without going into all the details, this is basically cellular food for metabolism. Cellular death occurs during a typical cardiac arrest.
you can tell that researcher that O2, and getting the O2 into the coronaries and brain is paramount, and cellular death occurs after 4 minutes without it.

Last semester my instructor mentioned (off the books) that insulin is sometimes given during cardiac arrest. I forgot what she mentioned the action of this was, and I can't seem to find any information pertaining to it. Does anyone have any insight?
