ReviewProinflammatory, immunomodulating, and prothrombotic properties of anemia and red blood cell transfusions.
For many years, the traditional treatment for hospitalized patients in the United States who have developed anemia, whether associated with medical illness, surgical procedures or trauma, has been red blood cell transfusion, despite the absence of supporting data in many patient populations. Emerging evidence suggests that transfusions may, in fact, be associated with risk beyond commonly held concerns of microbial transmission and acute antigen-antibody reactions. The following overview represents a biological paradigm for understanding the relationship between medical illness, surgical procedures, inflammatory states, anemia, red blood cell transfusion and immunothrombotic phenomena among hospitalized patients.

The use of a HEMOCHRON JR. HEMONOX point of care test in monitoring the anticoagulant effects of enoxaparin during interventional coronary procedures.
Enoxaparin is increasingly used for the anticoagulation of patients undergoing percutaneous coronary intervention (PCI). Several reports have suggested the utility of using point of care tests in monitoring the anticoagulation levels of enoxaparin in patients undergoing PCI. The objective of this study was to evaluate a new point-of-care test (POCT) HEMONOX in monitoring the anticoagulant effect of enoxaparin in non citrated fresh whole blood samples from patients undergoing elective PCI procedure. ⋯ The HEMONOX test may be able to guide anticoagulation with enoxaparin during PCI. The HEMONOX assay is a one step whole blood coagulation test performed on the HEMOCHRON Jr. Signature + POC system. The method was evaluated to monitor the anticoagulant level of enoxaparin in blood samples from patients undergoing PCI after receiving an intravenous dose of 0.5 mg/kg. The results suggest a clear distinction of HEMONOX CT between the baseline value of untreated patients and patients achieving therapeutic enoxaparin levels.
