The impairment of formation and maintenance of a formed fibrin clot contributes to the prolonged bleeding and high incidence of rebleeding in upper gastrointestinal haemorrhage. To investigate the basis for the use of drug therapy in gastric bleeding, this study used thrombelastography to determine the effects of pharmacological manipulation of gastric juice on coagulation and fibrinolysis. The...

Background. Thromboelastography (TEG) unlike conventional coagulation assays evaluates the dynamic interaction of clotting factors and platelets indicating an overall clot quality. Literature assessing the efficacy of TEG in identifying trauma associated bleeding is lacking. Aim. To compare TEG with conventional plasma based coagulation tests and assess whether TEG can serve as a screening test...

We present a methodology for personalizing the clinical treatment of severely injured patients with acute traumatic coagulopathy (ATC), an endogenous biological response of impaired coagulation that occurs early after trauma and shock and that is associated with increased bleeding, morbidity, and mortality. Despite biological characterization of ATC, it is not easily or rapidly diagnosed, not a...

BACKGROUND Knowledge about the impact of Low-Molecular-Weight Heparin (LMWH) on the coagulation system in patients undergoing minimal invasive lung cancer surgery is sparse. The aim of this study was to assess the effect of LMWH on the coagulation system in patients undergoing Video-Assisted Thoracoscopic Surgery (VATS) lobectomy for primary lung cancer. METHODS Sixty-three patients diagnosed...

BACKGROUND Hydroxyethyl starches (HES) accumulate in the circulation when administered repeatedly. Accumulation is thought to be partly responsible for undesirable effects (tissue storage, blood coagulation impairment, and itching). HES 130/0.42 with low molecular weight and a low level of substitution has recently been developed in order to reduce those risks. METHODS In healthy volunteers, ...

INTRODUCTION Coagulopathy can occur after hemorrhage, trauma and resuscitation, and has been associated with dilution of coagulation factors and hypothermia. Recombinant activated Factor VII (rFVIIa) has been used, often as a last resort, to improve hemostasis in trauma/hemorrhage patients with coagulopathy. The aim of this study was to further characterize the effects of rFVIIa on various coag...

Ultrasonic processing in the cavitation mode is used to produce composite materials based on metal matrix and reinforcing particles of micro- nano-sizes. In such a case, deagglomeration aggregates uniform distribution are expected effects. Although can not only fragment acoustic field, they also coagulate, coarsen precipitate. this paper, theoretical study processes coagulation liquid under ult...

BACKGROUND AND OBJECTIVES Since the impairment of platelet function may cause excess peri-operative bleeding, pre-operative discontinuation of aspirin and heparin bridging are common for cardiac surgery. We evaluated the impact of pre-operative administration of enoxaparin and unfractionated heparin (UFH) on coagulation parameters and peri-operative bleeding in patients undergoing elective coro...

Abstract A data-based multivariate method such as response surface methods and desirability function is considered advantageous for analysing coagulation treatment optimization. Thus, this study investigated the optimization of coagulation–flocculation using methodology. The parameters were pH, alum dose alkalinity. optimum conditions individual responses: turbidity, colour, residual aluminium ...

OBJECTIVES Cadmium (Cd) is a persistent and widespread environmental pollutant, which may constitute a potential risk factor for hormone-dependent tumors such as endometrial cancer. The vascular endothelium is an important target of cadmium toxicity, which may interfere with the coagulation cascade and fibrinolytic system. The aim of this research was to investigate whether in female patients w...
