Title (EN) CONTINUOUS HEMODIALYSIS USING CITRATE
(FR) HEMODIALYSE CONTINUE UTILISANT DU CITRATE
Abstract:
(EN) The present invention provides a method of preventing blood from clotting in a filter during continuous arteriovenous or venovenous hemodialysis on a patient comprising administering to the blood an amount of citrate sufficient to prevent clotting in the filter. The invention preferably utilizes a dialysate having a sodium and calcium concentration below that of normal blood and an alkali concentration sufficiently low to reduce or prevent alkalosis.
(FR) L'invention concerne un procédé empêchant le sang de se coaguler dans un filtre pendant une hémodialyse continue artérioveineuse ou veinoveineuse chez un patient, et consistant à administrer au sang une quantité suffisante de citrate pour empêcher le sang de se coaguler dans le filtre. L'invention utilise de préférence un dialysat ayant une concentration en sodium et en calcium inférieure à celle du sang normal et une concentration alcaline suffisamment faible pour réduire ou empêcher une alcalose.
