Making IVF mix with D10% and D 50% (or any two solutions of different dextrosity)

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
