BACKGROUND Coagulation can be visualised using whole blood coagulation analyses such as thromboelastometry and platelet aggregation tests; however, the role of temperature in the analyses is ambiguous. The aim was to examine whether temperature influences the whole blood coagulation tests. METHODS We included 40 patients treated with targeted temperature management (33 ± 1 °C) after out-of-ho...

Coagulopathy in critically ill patients is common and of multifactorial origin [1]. Coagulopathy-associated risk of bleeding and the use of allogeneic blood pro ducts are independent risk factors for morbidity and mortality [2,3]. Th erefore, prompt and correct identifi cation of the underlying causes of these coagulation abnormalities is required, since each coagulation abnormality necessitate...

Two women, aged 81 and 61, became haemorrhagic after surgery. Their previous surgeries were uneventful with no unexpected bleeding observed. Blood tests prior to the current surgeries indicated normal values including those related to coagulation. There were no problems with the current surgeries prior to leaving the operating room. At 3 hours after the surgery, the 81-year-old patient had an o...

The objectives of this study were to measure the bleeding volume associated with fibreoptic bronchoscopy with transbronchial biopsies (TBB), to correlate it with coagulation tests and to compare bleeding volume in patients with and without lung transplant. A total of 104 consecutive TBB in 51 different patients was evaluated prospectively. Before each procedure, haemoglobin, blood platelets, pr...

BACKGROUND & AIMS Wilson disease (WD) is an autosomal recessive disorder of copper metabolism. Alterations of copper metabolism have been associated with changes in coagulation factors. The aim of the present study was the analysis of coagulation factors in WD patients. METHODS 100 patients attending a tertiary WD outpatient clinic were analyzed in a prospective cross sectional cohort study. ...

INTRODUCTION This section covers the means, as far as we now know them, by which components of the blood plasma produce an insoluble protein meshwork, or gel, at a site of blood-vessel damage. The plasma is normally completely fluid, containing all its proteins in soluble form. When the clotting system is activated at a site of blood-vessel damage, a series of proteolytic reactions is set going...

The possibility of bioterrorism is a looming threat. Potentially deadly biological agents are being studied for their uses in today’s technologically advanced warfare, and the medical community is not prepared for the results of such an attack. Many potential bioterrorist agents may have a significant impact on blood coagulation, because of their effects on immune and inflammatory pathways. Bio...

BACKGROUND Intensive care unit (ICU) patients usually have abnormal biochemical and hematological laboratory test results as a consequence of organ dysfunction and underlying disease. Thromboelastography (TEG®) is a point-of-care laboratory analysis that gives an overview of several aspects of the coagulation process. In order to be able to perform a clinical interpretation of abnormal TEG® res...

INTRODUCTION The emergency laboratory in Hacettepe University Hospitals receives specimens from emergency departments (EDs), inpatient services and intensive care units (ICUs). The samples are accepted according to the rejection criteria of the laboratory. In this study, we aimed to evaluate the sample rejection ratios according to the types of pre-preanalytical errors and collection areas. M...
