Intensive Care Electrolyte Replacement Orders for Hypothermia Therapy

1. The Ordering of replacement protocols automatically discontinues previous (prn, one-time) replacement orders for

each electrolyte ordered.

2. The physician indicates which orders to initiate. These orders will remain in effect until the patient is discharged from the ICU or contraindications are present.

3. Contraindications to using these replacement protocols include:

-Serum creatinine greater than (>) 2 (M.D. may write an order to give at a higher level)

-Urine output less than 200cc over previous eight hours

4. Based on physiological interactions, if several electrolytes are known to be low, they should be replaced in the following order: (This is not an order for additional labs.)
