Reasons for needing a sodium bicarbonate (bicarb) drip are discussed in excellent posts by Pulm Crit and LITFL. One can be made by mixing the following:
- 1 liter D5W, remove 150 ml from bag
- 3 ampules of 8.4% NaHCO3 (50 mEq each in 50 ml), inject each into the D5W bag
- Mixing the infusion above yields 150 mEq/L at 300 mOsmol, which is slightly higher than serum concentrations.
- Infuse 1 liter @ 200 ml/hr (urine alkalinization) up 1 L/hr (cardiac arrest with poor pressors response), depending on indication.
