Thromboelastography (TEG) has been used increasingly as an intraoperative hemostasis monitoring device. Low-molecular-weight heparins are given increasingly to reduce the development of antibodies against the heparin–platelet factor 4 complex, and heparinoids are given to patients who have developed the antibody. We studied the effect of unfractionated heparin, a low-molecular-weight heparin (e...

In this work the suitability of some Tibased coatings as coating for blood-contacting implants is analyzed. Layers of pure Ti, Ti nitride, Ti oxynitrides (TiN1-xOx with x = 0.25, 0.50, and 0.75) and Ti oxides were deposited from a plasma produced by cathodic arc evaporation under addition of N2 and/or O2. The oxynitrides are crystalline with the fcc structure of TiN up to x = 0.25. For x = 0.5 ...

The prevalent assertion that scientific progress is encumbered by the problem of communication gains special validity when directed to the medical sciences. So profuse is the number of publications appearing that keeping abreast of one's specialty is difficult, reading the literature on other subjects a near impossibility. Yet most authorities would agree with Fremont-Smith that "nature is of o...

In cardiac surgical patients we investigated the effects of cardiopulmonary bypass (CPB) with a hollow fiber membrane oxygenator on blood clotting measured by thromboelastography (TEG). We found only a minimal change in the strength of blood clot described either by the TEG parameter MA (maximum amplitude) or by the shear modulus G calculated from MA. After CPB there was also a significant tend...

Y ou or a family member may have developed a blood clot in one of the deep veins in the body (ie, a deep vein thrombosis, or DVT) or had a blood clot that traveled to the lungs (ie, a pulmonary embolism, or PE). As part of your medical care, your doctor may have evaluated you for conditions that may have contributed to developing a blood clot. Thrombophilia is a condition in which there is an i...

Oral anticoagulants (OAC) are intended to enhance the unwanted activation of blood clotting, and they used for prophylaxis treatment thromboembolic events. This study aimed describe verify whether there was a relationship between patient compliance with OAC therapy gender age, using sample 111 individuals. The data were collected through individual forms, from patients in Hospital Unit Great Li...

Blood rheology is completely determined by its major corpuscles which are erythrocytes, or red blood cells (RBCs). That is why understanding and correct mathematical description of RBCs behavior in blood is a critical step in modelling the blood dynamics. Various phenomena provided by RBCs such as aggregation, deformation, shear-induced diffusion and non-uniform radial distribution affect the p...
