Mechanism of Hypokalemia in Magnesium Deficiency

In the ICU, we are at times obsessed with making our patients “euboxic” or better said, all labs values within normal ranges. That being said, electrolytes are something we replete every day and our nurses often have protocols which instruct them on how to manage and correct these derangement to hopefully optimize the outcomes of our patients. When I was a resident, one of my mentors and a good friend to this day taught me to correct the Magnesium before correcting the potassium. This left me scratching my head. It made no sense. And the he went on to explain the mechanisms listed in this article and my mind was blown. How much other stuff do I not know? How come I wasn’t taught this in med school? Well friends, there A LOT that we weren’t taught in med school or even residency and fellowship training for that matter. That pretty much why I’m on this lifelong learning journey and hopefully bringing you all along for the ride. This article is free and it’s a good review for you all to check out. To the cool nurses on Instagram, mid sharing this with your colleagues? This is also must know medicine for any internal medicine intern and resident working the wards and ICU. Tony Breu totally killed this subject in a much more thorough and intelligent manner than I did several months ago on twitter. Follow him @tony_breu.
