22 Sep 2015 The currently available evidence indicates that point-of-care tests may be applied to guide appropriate blood product transfusion and the use of hemostatic therapy prohemostatic agents [9], but has recently re-emerged in various automated and computerized forms as a point-of-care test that can be used
disciplines can reduce the likelihood that a patient will require an allogeneic blood transfusion. The clinical practice described in this document primarily focuses on the point of care coagulation testing (POCCT) component of a bleeding management treatment protocol implemented at The Prince Charles Hospital. The use
Published reports are available on the use of TEG to guide the management of trauma patients,23,24 cardiac surgery patients25 and during postpartum bleeding.26 The evidence on the use of TEG for guidance of transfusion therapy will be discussed below. For the majority of clinicians managing these bleeding patients,
While the rapidly available bedside haemoglobin measurements can guide the transfusion of red blood cells, blood product administration is guided by many in vivo . The aPTT is used as a screening tool for haemophilia A, haemophilia B, coagulation inhibitors and to monitor unfractionated heparin therapy[1] [Table 1].

61 The INTEM test uses ellagic acid to initiate clotting via the intrinsic pathway, whereas the HEPTEM assay uses heparinase in addition to ellagic acid. involving cardiac patients have validated the correlation between FIBTEM tracings and fibrinogen status and have used results of this assay to guide transfusion therapy,
screening of donations, compatibility testing, storage of donations for clinical use, issue of blood units for . Transfusion should be prescribed only when the benefits to the patient are likely to outweigh the risks. . 1.2 g/dL and haematocrit (Hct) 35-45% with no functional platelets or labile coagulation factors (V and VIII)
8 Sep 2014 Papers were included if PT, INR, or aPTT were measured, a threshold for the results of the SLTs was given to determine coagulopathy or the results were used to guide treatment, and the outcomes of interest for this review (blood loss, time to haemostasis, transfusion requirements, mortality) were reported.
1 Dec 2009 Heparin monitors, platelet function monitors for use in transfusion algorithms, and monitoring anti-platelet drugs will be discussed. rapid bedside monitoring to aid the clinician in directing appropriate targeted therapy.59,62 The majority of POC devices used today can perform multiple coagulation tests.
Thromboelastography as a guide for transfusion therapy in a patient with Turner's syndrome, hypoplasia of the aortic arch and aortic coarctation, undergoing recently described and it requires extensive suture lines and an accurate management of coagulation disorders associated with the use of extracorporeal circulation.
