Severe trauma-related bleeding is associated with high mortality. Standard coagulation tests provide limited information on the underlying coagulation disorder. Whole-blood viscoelastic tests such as rotational thromboelastometry or thrombelastography offer a more comprehensive insight into the coagulation process in trauma. The results are available within minutes and they provide information ...

BACKGROUND Each year in the UK, ≈3000 children undergo major cardiac surgery requiring cardiopulmonary bypass. Approximately 40 % of these experience excessive bleeding necessitating red cell transfusion or treatment with other blood components. A further 40 % receive blood components because of the perception by clinicians that the risk of bleeding is high. Excessive bleeding and treatment wit...

Cutaneous bruises are a common symptom and a sign of injury and blood coagulation disorders in childhood. A carefully-taken history, coupled with a thorough physical examination, would lead to the diagnosis, or guide the clinician to the necessary laboratory investigations. Most children suffering from non-accidental injury can have their diagnosis established on clinical grounds alone and do n...

glucoronoxylomannan (gxm) is the most important compound of polysaccharide capsule in cryptococcus neoformans that causes infection in its recognition as a foreign agent by immune system. because of its similarity with some naural compounds such as heparin and hyaloronic acid, this study was undertaken to determine the effect of polysaccharide compounds on blood coagulative process and renal pe...

BACKGROUND Vascular targeting of malignant tumors has become a clinically validated new treatment approach with clear patient benefit. However clinical studies have also revealed that some types of vascular targeting agents (VTAs) are prone to coagulation system side effects. It is therefore essential to predetermine coagulation parameters in preclinical studies. As of to date, this has rarely ...

Introduction The coagulation cascade is a dynamic process dependent on many factors. It involves interaction between primary hemostasis, platelet clot formation, secondary hemostasis, thrombin generation, and fibrinolysis. The assessment of this process is particularly important in the surgical patient to properly assess patient coagulation assessment, manage hemostatic therapy and transfusion ...

In this study of coagulation operation, a comparison was made between the optimum jar test values for pH, coagulant and coagulant aid obtained from traditional methods (an adjusted one-factor-at-a-time (OFAT) method) and with central composite design (the standard design of response surface methodology (RSM)). Alum (coagulant) and polymer (coagulant aid) were used to treat a water source with v...

Argon plasma coagulation (APC) is a common and safe bronchoscopic technique used in the management of obstructing lesions and hemorrhage in the central airways. Complications of bronchoscopic APC are uncommon and include hemorrhage, perforation and fire in the airways. While bronchoscopic APC has been reported to cause systemic gas embolization and associated cardiovascular collapse, we report ...

objective(s): echis carinatus is one of the venomous snakes in iran. the venom of iranian echis carinatus is a rich source of protein with various factors affecting the plasma protein and blood coagulation factor. some of these proteins exhibit types of enzymatic activities. however, other items are proteins with no enzymatic activity.   materials and methods: in order to study the mechanism an...

conclusions based on our results, it seems that there were no cases of obi among chronic hcv-infected patients with thalassemia and bleeding disorders, particularly hemophilia. however, to improve decisions concerning obi screening, especially in transfusion centers, and concerning the use of comprehensive screening methods, more original studies with more precise laboratory techniques and larg...
