What is the composition of the final solution that you inject? If I'm right you inject 100g of sodium ascorbate on 1000ml of NS. RIght? And with this solution do you get a 7,4 pH?
Do you know the pH of the NS solution that you use?
I believe, Perico, this has to do with warning a person not to over-alkalinize their blood [please, anyone here correct me if they see it differently]. If you are monitoring the pH of your solution(s), this will not be a factor, e.g. it is my understanding that [healthy] human blood is generally around a pH of 7.35 to 7.45.I have read that intravenous sodium bicarbonate must not be used every day for long periods of time...
-eDOC: The NS that we can get here in the market has a pH between 5,5 and 6,5 (mainly 5,5, rarely 6,5), could you tell me with which substances can we buffer to reach the 7,4? We would need too, the maximum quantities of the buffers to feel confident. I'm form the periphery of Spain eDOC, but I usually go to Madrid. You are from China right? but do you work in the US?
Hi everyone,
We are having trouble with the solution's pH. With a solution of 50g of sodium ascorbate, purity of 100% according to the technical sheet (we buy the powder in a compounding pharmacy), on 500ml of normal saline we get a 6,0 pH. Impossible for us to reach the 7,4 or superior that Carthcart, Levy, eDOC and others reach.
What is going wrong?
