OK, so critical care seems as good a place as anywhere to ask this question!
I've been looking at junior doctors knowledge of fluid prescribing in general, and one of the questions I asked was the electrolyte composition of various commonly prescribed fluids - Normal Saline, DexSaline, 5% Dex, Hartmann's and Gelo.
Now, most people got N Saline right (phew!), but as I had thought, everyone hugely overestimated the amount of sodium in DexSaline.
I personally don't like DexSaline, and hardly ever prescribe it. It got me thinking though - when should it be used? I've seen it used in paeds, but no where else, but then I'm fairly new to the whole doctoring lark.
So here's my question: What is DexSaline actually for?
(For those who want to know - 154 mmol Na in N Saline, 30 mmol (not 70-75!) in DexSaline)
