2 in 1 Formulations
Dextrose and AA Flexibility in amount of aa and dextrose See precipitation In line filter to remove particles in solution Less microbial growth
3 in 1 Formulations
Decrease time to administer lipids separately
Factors which help to stablizer Lipid Emulsions (3 in 1)
High pH >5.0 Low dextrose concentration Low protein concentration Low amounts of divalent cations Avoid use of trivalent cations Add lipids LAST
46.8 mEq NaCl ordered
3% stock solution NaCl
3% = 513 mEq/1 L = 0.513 mEq/mL
How many mL of NaCl?
46.9 mEq | 0.513 mE
X mL 1 mL
X = 91 mL NaCl
Factors that enhance Ca:P Stability
Ca gluconate Low product ratio Add P then Ca last Refrigerate Infuse within 24 hrs Less than 6.0 High dextrose Addition of l-cysteine Amino acids
