Dialysis treatment using an ethylene vinyl alcohol membrane and no anticoagulation for chronic uremic patients.
Anticoagulation used in hemodialysis treatment brings with it the risk of hemorrhagic complications and the possible consequences associated with chronic heparin administration. These problems have not been satisfactorily addressed to date. This study examined a new dialysis method that does not require the administration of anticoagulants. Dialysis is performed for 3 h with a continuous infusion of 750 ml of physiological saline solution in predilution mode and using filters made of ethylene vinyl alcohol copolymer membranes. Eleven patients with chronic uremia underwent more than 2,000 dialysis treatments performed with 9 episodes of coagulation of the dialyzer or blood tubings (0.43%). An evaluation of individual treatments revealed a high degree of biocompatibility and only a scanty activation of coagulation. Blood depuration efficacy was very good as evaluated from pretreatment and posttreatment routine blood chemistries. The technique described here represents a simple and effective method for performing regular dialysis treatment and does not require anticoagulant therapy.
