What concentration norepinephrine infusion does your institution use for patients with epidurals and having C-section? Do your anesthesiologists prepare this in the OR or do you have a standard concentration for them to pull and hang? It has come to light that our anesthesiologists are preparing and using an 8mcg/mL infusion and now would like this built in our EHR so they can document. Our standard concentration is 16mcg/mL - which we prefer to use. Peripheral infusion safety studies range from 4mcg/mL - 64mcg/mL and duration 20 min - 49 hours with all concentrations reporting some extravasations.
