Background: Bleeding assessment tools are key components in the evaluation of patients suspicious for bleeding disorders. The exact determination of the normal ranges of ISTH-BAT (International Society on Thrombosis and Hemostasis –Bleeding Assessment Tool) in the healthy population is a crucial step for determining who needs to be referred for further coagulation laboratory examinations. We ai...

BACKGROUND Hydroxyethyl starch (HES) may affect blood coagulation. We studied the effects of a modified, balanced, high-molecular weight [mean molecular weight (MW) 550 kDa], high-substituted [degree of substitution (DS) 0.7] HES preparation (Hextend) on coagulation in patients undergoing major abdominal surgery. METHODS Patients were allocated randomly to receive Hextend) (n=21), lactated Ri...

BACKGROUND Hypothermia may be accidental or therapeutic. Therapeutic hypothermia is increasingly used as treatment for various conditions, e.g., neuroprotection after cardiac arrest. Hypothermia leads to an impairment of the coagulation system, but the degree of impairment has been difficult to determine. Most studies have been performed on plasma instead of whole blood. We therefore evaluated ...

In order to find out the sensitive tests to differentiate intravascular coagula tion from intravascular proteolysis, the changes in factors of coagulation fibrinolysis were studied on experimentally produced fibrinolysis, fibrinogenolysis and intravascular coagulation. Fibrinogen, and factors V and VIII were decreased; the prothrombin time, thrombin time and partial thromboplastin time were pro...

Background: Coagulopathy is a common manifestation in cases of snake bite and its abnormality can be detected by blood coagulation tests. There are very few references in the literature related to coagulation parameter abnormalities after snake bite, evaluation of their seriousness and the length of the follow up period. Therefore we have undertaken this study to throw some light on the need of...

This study assessed the effect on coagulation tests of fresh frozen plasma (FFP), given according to guidelines compared with higher doses in critically ill patients. Group 1 (10 patients) received 12.2 ml/kg and group 2 (12 patients) 33.5 ml/kg FFP. Prothrombin time, activated partial thromboplastin time and factors I-XII were measured before and after FFP infusion. Factor levels of 30 IU/dl (...
