WitrynaHeparin resistance is a prevalent issue in severe burns. Nucleosome levels were increased post-burn, and showed an inverse association with AFXa consistent with the hypothesis that they may interfere with the anticoagulant effect of heparin in vivo and contribute to heparin resistance. Accurate monitoring of AFXa activity with … Witrynalation effect of LMWH is not reflected by the aPTT. Assessment of LMWH activity requires assessment of the antifactor Xa level, a test that is not universally available and has a longer turnaround. Higher cost.Another limitation of LMWH is its cost.
