In other words, if you add 50 grams sodium ascorbate to a .9% sodium chloride bag with a 350MMoL osmolarity, dextrose is 272 MMoL. So what is sodium ascorbate?
Riordan says to never exceed a solution of 1200 MMoL, but it sounds like 50 grams sodium ascorbate alone could exceed that in 1000ml. It donates 5grams of sodium alone, plus another 45 of a solution that needs to be absorbed. Thats a lot of stuff
