[Monitoring the efficiency of heparin anticoagulation in patients on programmed hemodialysis].

The activated partial thromboplastin time (APTT) test is widely used to monitor heparin anticoagulation. The relationship of the APTT to the activity of administered unfractionated heparin was defined in 23 patients on programmed hemodialysis, by using six APTT reagents. A calibration curve was plotted for each reagent.

[Use of continuous high-volume hemofiltration in patients with sepsis and multiple organ dysfunction].

The paper gives the authors' experience in performing continuous high-volume hemofiltration in 38 patients with sepsis and multiple organ failure. The kinetics of proinflammatory cytokines and a number of plasma enzymes as markers of substances having a relatively high molecular mass was studied. The advantages of a procedure using an artificial kidney apparatus equipped with an on-line substituting fluid preparation system are described.
