Web• Citrate is metabolized to citric acid in the liver, which generates bicarbonate. • Each mmol of citrate generates 3 mmol of bicarbonate. • Citrate can by this process be used as an indirect buffer. • The citric acid, also generated in citrate metabolism, enters the Krebs cycle in skeletal muscles and the renal cortex. WebNov 3, 2024 · Regional Citrate Anticoagulation is the infusion of citrate into the blood circuit during renal replacement therapy (RRT) to chelate ionized Ca2+ forming calcium-citrate complexes, thus preventing coagulation of blood. calcium is required for the generation of thrombin (involved in the activation of factors II, IX and X)
