Rotation thromboelastometry (ROTEM) is a viscoelastometric point-of-care-test for the complex evaluation of changes in hemostasis, performed in whole blood. However, no prospective study evaluating the efficacy of the antiplatelet therapy using ROTEM was performed.Fifty-six patients (34 men, 22 women, mean age 67.75 years, and age range 34-88 years) with acute ST-elevation myocardial infarction (STEMI), treated with dual antiplatelet therapy, undergoing urgent coronary angiography and percutaneous coronary intervention (PCI) of culprit coronary lesion were included...

BACKGROUND: Activated methods of thromboelastometry such as EXTEM and INTEM are routinely used in management of severe bleeding. However, sometimes the patient is bleeding despite the normal values of EXTEM/ INTEM. Non-activated thromboelastometry (NATEM) is the most sensitive to coagulopathy and shows pathologic results in such cases. However, it is necessary to find an appropriate time interval between blood sampling and NATEM analysis as the results are strongly influenced by time...

BACKGROUND: Perioperative anemia and blood product transfusion increases short-term and long-term morbidity and mortality during cardiac surgery. We hypothesized that streamlined cardiopulmonary bypass circuit and rotational thromboelastometry (ROTEM) would reduce blood product usage and improve outcomes. METHODS: All patients with Society of Thoracic Surgeons risk scores at our institution from January 2013 to June 2015 were included. Individuals were chronologically stratified into 2 groups according to institutional changes to a streamlined bypass circuit and ROTEM-guided transfusion...

BACKGROUND: Dengue virus infection (DVI) is a prevalent and potentially fatal viral disease associated with coagulopathy. So far, the coagulation profile of DVI patients with thrombocytopenia has not been assessed through a viscoelastic test such as rotational thromboelastometry. We aimed to describe the prevalence and characteristics of coagulation abnormalities in dengue fever outpatients with thrombocytopenia, addressed by both rotational thromboelastometry and conventional coagulation tests...

A 72-year-old woman with antiphospholipid syndrome underwent aortic valve replacement. Her preoperative activated partial thromboplastin time was 61.7 seconds and activated clotting time was 219 seconds. During cardiopulmonary bypass, the Hepcon Hemostasis Management System (HMS) Plus determined the heparin dose needed to maintain whole-body heparin at 3 U/mL. After cardiopulmonary bypass, 100 mg of protamine was administered based on heparin-protamine neutralization, and the activated clotting time decreased...

INTRODUCTION: The absence of a reliable clinical test to predict bleeding tendency leaves factor XI (FXI)-deficient individuals at risk of overtreatment or under treatment. AIM: To assess whether rotational thromboelastometry has value in detection of FXI deficiency and identification of bleeding tendency. METHODS: Thromboelastometry was measured in whole blood and platelet-rich plasma (PRP) samples containing corn trypsin inhibitor (CTI) from controls (n = 50) and FXI-deficient individuals (n = 93) at tissue factor (TF) 0...

Although endoscopic transurethral resection of the prostate (TURP) is a well-established procedure as a treatment for benign prostatic hyperplasia, its complications remain a concern. Among these, coagulopathy may be caused by the absorption of irrigating fluid. This study aimed to evaluate such phenomenon using a rotational thromboelastometry (ROTEM).A total of 20 patients undergoing TURP participated in this study. A mixture of 2.7% sorbitol-0.54% mannitol solution and 1% ethanol was used as an irrigating fluid, and fluid absorption was measured via the ethanol concentration in expired breath...

Coagulopathy and severe bleeding are associated with high mortality. We evaluated haemostatic treatment guided by the functional viscoelastic haemostatic assays, thromboelastography or rotational thromboelastometry in bleeding patients. We searched for randomised, controlled trials irrespective of publication status, publication date, blinding status, outcomes published or language from date of inception to 5 January 2016 in six bibliographic databases. We included 17 trials (1493 participants), most involving cardiac surgery...

Amniotic fluid embolism (AFE) is an unusual cause of life threatening peri partum hemorrhage (PPH). AFE resuscitation is often associated with renal and respiratory insufficiency, and a coagulopathy similar to disseminated intravascular coagulation (DIC). Resuscitation requires immediate recognition and limited use of crystalloid. We present a case of PPH caused by AFE with resultant cardiac arrest, renal and respiratory failure, and DIC-like coagulopathy, whose successful resuscitation was guided by perfusionist-directed serial thromboelastography (TEG)...

BACKGROUND: Patients undergoing liver transplantation (LT) have a high risk of bleeding. The goal of this study was to assess whether the first derivative of the velocity waveform (V-curve) generated by whole blood rotation thromboelastometry (ROTEM(®)) can predict blood loss during LT. METHODS: Preoperative V-curve parameters were retrospectively evaluated in 198 patients. Patients were divided into quartiles based on blood loss: low (LBL) in the first quartile and high (HBL) in the higher quartiles...

Perioperative bleeding remains a major complication during and after surgery, resulting in increased morbidity and mortality. The principal causes of non-vascular sources of haemostatic perioperative bleeding are a preexisting undetected bleeding disorder, the nature of the operation itself, or acquired coagulation abnormalities secondary to haemorrhage, haemodilution, or haemostatic factor consumption. In the bleeding patient, standard therapeutic approaches include allogeneic blood product administration, concomitant pharmacologic agents, and increasing application of purified and recombinant haemostatic factors...

There is increasing interest in the synthesis of low molecular weight heparin and heparan sulfate mimetic polymers because of their various potential biomedical applications. The functional activity of heparin and heparan sulfate is believed to arise from the presence of a number of functional groups, such as hydroxyl, carboxylate and sulfate groups. The design and synthesis of novel heparin-mimetic polymers with a particular functionality poses a formidable challenge and requires carefully control of the selective conversion of functional groups on the polymer chain...

BACKGROUND: Different types of fresh-frozen plasma (FFP) exist, and the concentrations of plasma proteins vary between individuals and blood groups. Furthermore, processing may also influence the content. Quarantine-stored plasma (qFFP) and plasma that was pathogen-reduced using blood-safety (Intercept) technology (piFFP) were analyzed regarding procoagulant and anticoagulant hemostasis proteins, including endogenous thrombin (thrombin-generation) potential (ETP). MATERIALS AND METHODS: Thirty-five samples of each type of FFP were analyzed using only male Blood Group O donors...

Rotation thromboelastometry is a viscoelastometric method that provides a rapid assessment of a patient's hemostatic processes in emergency settings, allowing prompt identification of specific coagulation abnormalities. Its results thus might guide targeted replacement therapy in hemorrhagic conditions, in case of platelet or coagulation factor deficiency, or hyperfibrinolysis, which is difficult to identify otherwise. Although currently used in emergency and traumatic surgery, there are limited data about thromboelastometry in ischemic stroke, particularly in monitoring the coagulative response to recombinant tissue plasminogen activator after intravenous thrombolysis (IVT)...

BACKGROUND: To make plasma readily available to treat major hemorrhage, some centers are internationally using either thawed plasma (TP) or "never-frozen" liquid plasma (LP). Despite the routine use of both, there are limited data comparing the two. The hemostatic properties of LP were evaluated and compared to TP in a paired study. STUDY DESIGN AND METHODS: Two ABO-matched plasma units were pooled and split to produce 1 unit for LP and 1 unit for TP. Samples of TP and LP, stored at 2 to 6°C, were tested for a range of coagulation factors, thrombin generation, and rotational thromboelastometry...

INTRODUCTION: Previous guidelines recommend that FXI:C levels should be used to monitor FXI replacement in factor XI (FXI) deficiency. However, FXI:C levels do not correlate with bleeding tendency in this disorder and may not be the optimal test by which to monitor and determine further treatment in the postoperative period. AIM: To assess whether the thrombin generation assay (TGA) and rotational thromboelastometry can be used to monitor FXI replacement peri-operatively in FXI deficiency and to determine if changes in FXI:C levels correlate with changes in thrombin generation and clot formation parameters following treatment with solvent-detergent fresh frozen plasma (SD-FFP)...
