Toxicokinetics of metformin-associated lactic acidosis with continuous renal replacement therapy.

A 70-year-old diabetic male patient with a baseline serum creatinine of 1.4 mg/dL presented with nausea and vomiting. He was diagnosed with metformin-associated lactic acidosis and acute kidney injury.

Effective ionic dialysance/blood flow rate ratio: an indicator of access recirculation in arteriovenous fistulae.

Effective ionic dialysance (EID) is an online measure of hemodialysis (HD) effective urea clearance that is calculated using changes in dialysate sodium conductivity. Effective ionic dialysance is blood flow (Q(b)) dependent. The presence of significant (> or =5%) access recirculation (sAR) during dialysis lowers EID at a given Q(b), thereby lowering EID/Q(b).
