Hi Scott,



By now I'm sure you've seen the work from Jaber's group on using bicarb in critically ill academic patients. Obviously there are limitations to the trial, not the least of them a negative primary outcome. And while the study wasn't powered to look a 28 day mortality or 7 day organ failure in those with a AKIN score of 2-3 I am sure many will take this positive secondary finding and run with it.



My biggest criticism was that they didn't break the study down into patients with anion gap metabolic acidosis (AGMA) vs. non-anion gap metabolic acidosis (NAGMA). I'm a big fan of your acid base pods and tend to agree with your take and the Forsythe paper and don't give bicarb to patients with an AGMA. So I went ahead and emailed Jaber and he got back to me. He told me that "90% of the patients enrolled were hyperlactatemic." Moreover, most GI and renal patients with base loss were excluded b.c. bicarb was considered standard care, therefore the "large majority" had an AGMA. Interesting, now I'm second guessing myself and wondering if I should consider bicarb in AKIN patients with a AGMA.



I'm interested to hear your thoughts. I think it would make a great pod or a topic for Josh or Rory.



I hope all is well,



Keith
