Fellow-Level Lecture on Hyponatremia

Today I did a noon conference on sodium for the neph fellows. Instead of a comprehensive sodium lecture I focused on a number of different elements and interesting aspects of hyponatremia. Mostly a deeper dive into aspects that you don't have time to cover in standard sodium lecture.

I opened with 17 quick slides on free water clearance. These slides are old and I think I could do better. Definitely due for an update.

Then I used a slide deck which covers:

• mannitol as a cause of an osmolar gap and pseudohyponatremia
• glycine induced pseudohyponatremia
• a bit of data on rapid correction of sodium by hemodialysis
• exercise induced hyponatremia
• use of FeNa and FeUrea and FeUric acid to distinguish between salt depletion and SIADH

It was a fun lecture and everyone participated in a casual and interactive freewheeling learning session. Great stuff.
