In septic shock burn patients, citrate for CVVHDF was efficient and safe, and superior to heparin for hemorrhagic complications and filter survival. Observed metabolic stability was most likely due to a marked loss of citrate in effluent volume and subsequent low total citrate load for the patient.

In septic shock patients with liver dysfunction citratemia is useful in guiding clinical application of RRT, where the citrate losses in the ultrafiltrate can be efficiently modulated by increasing the effluent volume.

These results demonstrated that in refractory septic shock patients on CPFA at circuit citratemia of 6 mmol/L both HDF predilution and HF pre/postdilution were the best dialysis modalities to maintain a normal systemic citratemia through a high rate of citrate loss in the effluent.
