I was on call last night and the ER called with a case hyperkalemia. The ER was crazy (literally there was an active shooter in the ambulance bay moments before I received the call clickondetroit.com/news/local/202…)
So you need to be quick and precise with your questions.
How high is the potassium and is it confirmed on the EKG? It is always helpful to quickly establish that this is not pseudohyperkalemia. It was not.
Does the patient have a foley and are they making urine? Quickly correct urinary obstruction which can cause hyperkalemia and determine if you can use the kidneys to clear the potassium.
Every person who ever had a high potassium on labs was told to adopt a low potassium diet. Recently, a meta-analysis and systematic review looked into the data to support this. jrnjournal.org/article/S1051-…
Regarding the question of dietary restriction of potassium to lower serum K, there were 2 studies. TWO. And take a look at the weight of the two studies, Cockram has 90%. So in essence this meta -nalysis can just be replaced by looking at Cockram alone.
And Cockram is a weird study. It is all dialysis patients that were placed on liquid feeds and nothing but liquid feeds for two weeks. 🤮
