An investigation into the laboratory control of anticoagulant therapy is presented. The cases were divided into those in the first few weeks of therapy and those on long-term treatment. Variations in the levels of factors VII and X, and factor IX were assessed. Thromboplastin levels were used to control therapy. These were compared with parallel estimations by Thrombotest and with the levels of...
Mitchell J. Cohen discusses why trauma care must go beyond restoring perfusion to target disorders of inflammation and coagulation in severely injured patients.
Standard coagulation tests have a low specificity and sensitivity for diagnosing disseminated intravascular coagulation. The aim of this study was to determine whether whole blood thromboelastometry (TEM) detects lipopolysaccharide (LPS)-induced changes in coagulation. Blood samples from 10 pigs were drawn at baseline, before and at the end of LPS infusion and 2, 3, 4 and 5 h after the start of...
BACKGROUND Transfusion therapy is associated with increased morbidity, mortality and costs. Conventional coagulation tests (CCT) are weak bleeding predictors, poorly reflecting coagulation in vivo. Thromboelastometry (ROTEM) provides early identification of coagulation disorders and can guide transfusion therapy by goals, reducing blood components transfusion. OBJECTIVE The aim of this study ...
INTRODUCTION Today, the pneumatic tube transport system (PTS) is used frequently because of its advantages related to timing and speed. However, the impact of various types of PTS on blood components is unknown. The aim of this study was to examine the influence of PTS on the quality of routine blood cell counts, erythrocyte sedimentation, and certain blood coagulation tests. MATERIALS AND ME...
Coagulopathy associated with massive operative blood loss is an intricate, multicellular and multifactorial event. Massive bleeding can either be anticipated (during major surgery with high risk of bleeding) or unexpected. Management requires preoperative risk evaluation and preoperative optimization (discontinuation or modification of anticoagulant drugs, prophylactic coagulation therapy). Int...
BACKGROUND Bleeding complications in cardiac surgery may lead to increased morbidity and mortality. Traditional blood coagulation tests are not always suitable to detect rapid changes in the patient's coagulation status. Point-of-care instruments such as the TEG (thromboelastograph) and RoTEM (thromboelastometer) have been shown to be useful as a guide for the clinician in the choice of blood p...
