هپارین یک ماده ضد انعقادی است که در اعمال جراحی عروق، جهت پیشگیری از ترومبوز حین عمل استفاده می شود و پس از مدتی توسط پروتامین که یک داروی ضدهپارین است خنثی می شود. تزریق پروتامین می تواند عوارضی به همراه داشته باشد که این عوارض شامل کلاپس قلبی ـ عروقی، واکنش آنافیلاکسی، افت فشار خون، برادیکاردی و برونکواسپاسم هستند. همچنین دوز بالای آن منجر به تشدید اثر ضدانعقادی شده و باعث خونریزی می گردد. ای...
The clotting values of 50 patients with glomerulonephritis were examined. Three different coagulation groups were recognised: those with normal clotting values (group 1); those with high concentrations of factor VIII but otherwise normal clotting results (group 2); and patients who showed the presence of an activator of the intrinsic coagulation pathway, indicated by the presence of a short act...
BACKGROUND Hemorrhage and coagulopathy are major contributors to death after trauma. The contribution of red blood cells (RBCs) in correcting coagulopathy is poorly understood. Current methods of measuring coagulopathy may fail to accurately characterize in vivo clotting. We aimed to determine the effect of RBCs on clotting parameters by comparing resuscitation regimens containing RBCs and plas...
The process of human blood clotting involves a complex interaction of continuous-time/continuous-state processes and discrete-event/discrete-state phenomena, where the former comprise the various chemical rate equations (which can be written as differential equations) and the latter comprise both threshold-limited behaviors and qualitative facets of the coagulation cascade. We model this proces...
BACKGROUND A single bolus dose of LMW heparin at the start of haemodialysis effectively prevents clot formation in the dialyser and bubble trap. However, there are few studies on the appropriate dosage of LMW heparins in haemodialysis. Therefore we examined the relationship between the anticoagulant effect of dalteparin and clinical clotting during haemodialysis. METHODS We performed an open,...
