Table 2. The Protocol for Replacement of Electrolytes and Anticoagulation during CRRT.

Electrolytes
K+ (mEq/L)
>4.5	No KCl mix in the 5 L hemozol®
3.6-4.5	20 mEq KCl mix in the 5 L hemozol®
<3.6	40 mEq KCl mix in the 5 L hemozol®
P (mEq/L)
≥2.0	No phosten® mix in the 5 L hemozol®
<2.0	20 mL phosten® mix in the 5 L hemozol®
Anticoagulation
Initial
High risk	No anticoagulation/saline flushing
Low risk	Systemic heparinization
Maintenance
High risk-1	No anticoagulation/saline flushing
High risk-2	Regional anticoagulation (citrate or nafamostat)
Low risk	Systemic heparinization

CRRT, continuous renal replacement therapy.

Potassium and phosphate level check 2 times per day. Phosten®; potassium phosphate. Hemosol®; hemozol B0. Definitions; 1) High risk; active bleeding, post-operative within 48 hours, low platelet count <50000/mm³, prolonged PT/PTT ≥2.0 INR/60 sec. 2) Low risk; all patients except for high risk patients. 3) High risk-1 and high risk-2 were divided according to assessment of clotting in extracorporeal system during CRRT.
