For Na level <133 mEq/L or a decrease of 6 mEq/L in 24 to 48 hours: |
1. NaCl tabs 3 g PO/NGT every 6 hours |
2. Initiate 3 percent NaCl infusion at 20 mL/hour IV |
3. Check serum Na every 6 hours |
a. If Na <130 mEq/L: |
Increase rate by 20 mL/hour (max rate = 80 mL/hour) |
If on hold at present, initiate 3 percent NaCl infusion at 20 mL/hour IV |
b. If Na = 130 to 135 mEq/L: |
Increase rate by 10 mL/hour (max rate = 80 mL/hour) |
If on hold at present, initiate 3 percent NaCl infusion at 10 mL/hour IV |
c. If Na = 136 to 140 mEq/L: |
No change |
d. If Na ≥140 mEq/L: |
Hold infusion |
