THE RELATIONSHIP OF PLASMA PROTHROMBIN CONCENTRATiON AND THE DEGRADATION RATE OF SERUM “PROTHROMBIN- CONVERTING FACTOR” DURING DICUMAROL THERAPY
on fibrinogen and oxalated plasma revealed that serum obtained from recently coagulated whole blood contains a factor which causes conversion of prothrombin to thrombin.” 2 Since fibrinogen could not be converted to fibrin in any significant degree by addition of fresh serum, and since the rapidity of coagulation of oxalated plasma by the serum factor was proportional to the prothrombin concent...
متن کاملEffect of storage conditions on prothrombin time, activated partial thromboplastin time and fibrinogen concentration on canine plasma samples
The present study was to assess the effect of storage conditions on prothrombin time (PT), activated partial thromboplastin time (aPTT) and fibrinogen concentration in blood samples of healthy dogs. Thirty-five dogs of various breeds were included in the study. Citrated blood samples were obtained and plasma was divided into four aliquots to assess selected clotting parameters by means of a coa...
متن کاملPlasma Fibrinogen and D-dimer in Children With Sepsis: A Single-center Experience
Background & Objectives: In sepsis, enhanced fibrin formation, impaired fibrin degradation, and intravascular fibrin deposition lead to a prothrombotic state. The current study aimed at measuring various coagulation parameters to predict an early marker for disseminated intravascular coagulation (DIC). Methods: The current prospective s...
متن کاملDiagnostic utility of comparing fibrinogen Clauss and prothrombin time derived method.
A prothrombin time (PT) derived method has been described to measure plasma fibrinogen concentration. This method is not a direct determination of plasma fibrinogen but an estimation of the fibrinogen concentration from the absorbance changes at 450 nm (delta OD) during the clotting process of the PT on an automated photo optical coagulometers [1,2]. Although this assay is quick, economical and...
متن کاملImpact of fibrinogen concentrate alone or with prothrombin complex concentrate (+/− fresh frozen plasma) on plasma fibrinogen level and fibrin-based clot strength (FIBTEM) in major trauma: a retrospective study
BACKGROUND Low plasma fibrinogen concentration is a predictor of poor outcome in major trauma patients. The role of fibrinogen concentrate for rapidly increasing fibrinogen plasma levels in severe trauma is not well defined. METHODS In this retrospective study we included severe trauma patients treated with fibrinogen concentrate alone (FC group), fibrinogen concentrate with prothrombin compl...
