Advice Rapid potassium repletion in a pericoding patient with severely low K of 1.5 due to mismanaged DKA at outside hospital. How fast would you replete it? What is the fastest you have ever repleted K?
I repleted 40 meq via central line in less than an hour, bringing it up to 1.9. The pharmacist is reporting me for dangerously fast repletion. What I can tell you is the patient was able to breath much better shortly after the potassium was given. Pretty sure the potassium was so low he was losing function of his diaphragm. Any thoughts from docs or crit care who have experience with a similar case?

There must be a final decision maker - one who can weigh all factors, and make the best decision among difficult choices. That is the physician. Physicians are deeply trained precisely so that they CAN go beyond algorithms. Physicians MUST overrule the non-physicians who haven't seen, talked to, or examined the patient
NPs worship the Algorithms (AKA evidence based medicine) and when, as is inevitable, almost every patient at some point gets outside of the patient population described in the EBM paper, someone has to know what to do. And not be befuddled by the fact that their patient who has chest pain does not describe the chest pain precisely as angina is defined in the text books. Or be confused by the 28 year old with cardiac-like chest pain, who was told to go home because he couldn't be having a heart attack, he was too young. He was having post-viral pericarditis.
