Electrolyte Repletion Guideline
Potassium Repletion
- LOOK AT PHOSPOHORUS
- 3<K<3.5 and asymptomatic: oral (if able)
- <3.0: IV potassium
- K goes up .1 every 10 meq
- Max repletion rate: 1 meq /kg / day
- How to order: e.g. 10 meq in 50mL ran over 1 hour (times how much K needs to increase)
- PIV: 10meq/hr
- Central line: 20meq / hr
** use potassium acetate in presence of concomitant hyperchloremia
Magnesium repletion:
- 1g IV raises Mg .1
Sodium Repletion
- No more than 0.5meq/hour over 24 hours (12meq/day)
- Calculate!!
