Regional citrate anticoagulation and influence of recirculation on ionized calcium levels in the circuit.

Regional citrate anticoagulation is now widely used during continuous renal replacement therapy (CRRT), and especially in patients at risk for hemorrhagic complications. A close monitoring is required to avoid citrate overload, leading to metabolic alkalosis or citrate intoxication causing metabolic acidosis. This case report describes a dysfunction of the regional citrate anticoagulation due to the development of a deep vein thrombosis close to the site of insertion of the venous CRRT catheter.

[Management of suspected meningitis in the emergency department].

Febrile meningeal syndrome is a medical emergency. Lumbar puncture keeps its gold-standard status as clinical findings are neither sensitive nor specific enough. Antibiotics and steroids are ideally administered within the first 30 minutes after admission when bacterial meningitis is suspected.
