In many neonatal nursery IVF mix is made by adding sterile water and D 50%. Which is more costlier. We can make IVF mix by D10 and D50%.
Formula--
General formula for any two solutions with different dextrosity=
Total volume required= TV
ml of solution containing higher dextrosity(HD%)= X ml
ml of solution containing lower dextrosity(LD%)= TV- X ml
Desired dextrosity= DD
X ml = TV(DD-LD)/(HD-LD) ml of HD in TV
ml of LD in TV = TV- X ml
exp-
Total volume required is 100 ml
Desired dextrosity is 16% and we have D10 and D50%
HD=50%
LD= 10%
ml of D 50 (X ml) = 100(DD-10)/(50-10)
ml of D 50% ( X ml) =100(16-10)/40 ml
= 600/40 ml
= 15 ml
ml of D10%= 100-15=85 ml
