In most of the case, regional citrate anticoagulation is using diluted citrate around 1% depending on the types used in clinical practice. Diluted citrate is much more safer when compared to highly concentrated citrate around 4% or even more. In clinical practice, trisodium citrate is used in high concentration (around 30%) as a bactericidal agent with anticoagulant properties for locking deep venous catheters used in hemodialysis (HD; close to 25-30% of citrate). In this review article, buffer and anticoagulant potential of citrate are discussed during renal replacement therapy in critically ill patients with particular focus on the practical approach at the bedside.
