norepinephrine infusion concentrations

Our health authority currently utilizes 3 different concentrations of norepinephrine: 16 mcg/mL, 32 mcg/mL and 64 mcg/mL.
We’d like to reduce this to one concentration, which will likely be 64 mcg/mL (for fluid restricted patients). Does anyone have any experience using 64 mcg/mL concentration (or similar)? Concerns raised are:
- some patients are sensitive to norepinephrine and only need 0.03 mcg/kg/min (1.25 mL/hr in a 45 kg patient)
- is this too concentrated for a peripheral line start in Emergency, if not added to a Y-site with running fluids?

Thanks!
Cynthia
