Joining Brian and myself in our virtual studio is Dr Erica Tinson one of our fabulous lecturers in Emergency and Critical Care here at the RVC. Erica has an interest in a variety of topics though we thought that we would discuss the highs and lows of sodium. We focus on the management of the extremes of both, hopefully not something you see commonly, but we hope will help when you do. We hope that you enjoy.

Some equations of interest:
The Androgué-Madias formula:
Change in serum (Na+) = [infusate (Na+) – serum (Na+)] / total body water +1
Or
Change in serum (Na+) = [infusate (Na+) + infusate (K+) – serum (Na+)] / total body water +1
Free water deficit = {(current [Na+] /normal [Na+])-1} x (0.6 x body weight in kg)
Current Na+ is patients current plasma sodium concentration. Normal Na+ is the patients normal sodium concentration.

0:42.1 | So we were going to talk about sodium and I suppose the management of dysnitremia's, if you like, all the highs and lows of sodium. |
0:54.0 | So could I ask you sort of in, maybe in context, do you think you identify these patients, |
1:04.0 | what sort of patients are we talking about? |
1:06.0 | And do you think you identify them when they, when they sort of come in, or is it something that you actually just, you need to have an |
1:13.1 | electrolyte panel and are they presented cases or are they cases we're managing for a while |
1:19.4 | that suddenly get sodium sort of disturbances? What's your feel about the cases that we sort of see |
1:26.1 | with these problems? Yeah, I guess, yeah, as you say, we sort of see a range of these type of cases. |
1:31.5 | And sometimes they're presenting to us with the abnormality. |
1:35.8 | So coming through the door with either a low sodium or a high sodium or it's something that's developing in hospital. |
