Hemostas vid allvarlig blödning - PDF Free Download

Although TE has not been subjected to the same evaluation processes as conventional haemostatic tests, its use as a POCT monitor in complex major surgery has been shown to significantly reduce the use of blood component therapy and overall blood loss. When comparing suggested blood products using our TEG decision tree and an Intem based decision tree, both devices had the best agreements on transfusion of no products as guided by conventional tests, but lower agreement with abnormal conventional tests that would have resulted in blood component transfusion based on low fibrinogen levels (TEG and ROTEM- 0%), low platelets (TEG 44.4%, ROTEM 54.5%), or elevated PT or PTT (TEG 0%, ROTEM 22.2%). When comparing TEG to ROTEM, with additional Compared with transfusion guided by any method, TEG or ROTEM seemed to reduce overall mortality (7.4% versus 3.9%; risk ratio (RR) 0.52, 95% CI 0.28 to 0.95; I 2 = 0%, 8 studies, 717 participants, low quality of evidence) but only eight trials provided data on mortality, and two were zero event trials. Our analyses demonstrated a statistically significant effect of TEG or ROTEM compared to any comparison on the proportion of participants transfused with pooled red blood cells (PRBCs) (RR 0.86, 95% CI 0.79 to 0.94; I(2) = 0%, 10 studies, 832 participants, low quality of evidence), fresh frozen plasma (FFP) (RR 0.57, 95% CI 0.33 to 0.96; I(2) = 86%, 8 studies, 761 participants, low quality of evidence), platelets (RR 0.73, 95% CI 0.60 to 0.88; I(2) = 0%, 10 studies, 832 participants, low In general, ED physicians should consider using TEG or ROTEM in any patient with a serious or life-threatening bleed in order to identify coagulopathies that may be corrected. In the setting of trauma, studies have shown that both ROTEM- and TEG-guided treatment algorithms result in non-inferior patient outcomes and result in decreased overall usage of blood products compared to empiric massive transfusion protocols.

The two clinical studies TEG and ROTEM: The Basics TEG and ROTEM are close cousins that assess in real time the entire coagulation process, including fibrin formation and clot rate, strength, stability, and lysis. These two viscoelastic measures of whole blood provide essentially the same information on clot formation, kinetics, and strength, though they operate slightly differently. ROTEM and TEG technology provide real‐time, analysis of the viscoelastic properties of clot formation and dissolution in whole blood. Both ROTEM and TEG, using several samples run in parallel with a variety of activators and inhibitors, allow the processes of clot initiation, propagation, stabilization, and dissolution to be evaluated separately.

During a one-week period The RoTEM instrument analyses each parameter in a separate channel while in the TEG, all the parameters are analyzed simultaneously. In the TEG, the cup oscillates around the metal pin, whereas the pin moves around the cup in the RoTEM, conferring more stability against vibrations. Analysis 3.4.
