Membrane plasma separation: complications and

During the last 3 years, 306 membrane plasma separations (MPS) were performed on 40 patients. Activated partial thromboplastin time (APTT), oncotic pressure (OP), blood count, free hemoglobin, prothrombin time, fibrinogen, and factors II, V, VII, VIII, IX, X, XI, and XIII were determined. The complication rate was evaluated.
