[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. The heparinized and nonheparinized… (More)
