A Study of Blood Coagulation Following an Acute Stroke • A battery of blood coagulation tests were performed on 14 acute stroke patients. Various abnormalities were found, notably elevation of blood fibrinogen, factor VIII, prothrombin, platelet factor 3, and a shortened P.T.T. The significance of these findings is discussed and they are considered to be of no importance since similar changes w...
Patients undergoing cardiac surgery with cardiopulmonary bypass (CPB) are at increased risk for excessive perioperative blood loss requiring transfusion of blood products. Strategies to optimize administration of heparin and protamine and the assessment of their effects on coagulation are evolving in cardiac surgical patients. Two recent evaluations have focused on the use of multiple point-of-...
BACKGROUND In a whole blood coagulation test, the concentration of any in vitro diagnostic agent in plasma is dependent on the hematocrit level but its impact on the test result is unknown. OBJECTIVE The aim of this work was to clarify the effects of reagent concentration, particularly Ca2+, and to find a method for hematocrit estimation compatible with the coagulation test. METHODS Whole b...
BACKGROUND Presently the necessity of fasting time for coagulation tests is not standardized. Our hypothesis is that this can harm patient safety. This study is aimed at evaluating whether a light meal (i.e. breakfast) can jeopardize laboratory coagulation tests. MATERIALS AND METHODS A blood sample was firstly collected from 17 fasting volunteers (12 h). Immediately after blood collection, t...

Our knowledge of the blood coagulation system has expanded tremendously in the last 60 years. Many of the coagulation factors were identified through the detailed study of individual patients with a clear hereditary bleeding tendency. However, it became apparent by the mid-1950s that a unified nomenclature was desirable because many of the coagulation factors had been named independently by sev...
Bleeding problems often occur during the neonatal period. Although thrombocytopenia is the most common cause, coagulation problems often occur, and the two problems may co-exist. The causes, diagnosis, and management of coagulation problems in newborn infants are reviewed.
If the outcomes of the recent COAG meeting are implemented, Australia will have a new set of benchmarks for its health system within a few months. This is a non-trivial task. Choice of benchmarks will, explicitly or implicitly, reflect a framework about how the health system works, what is important or to be valued and how the benchmarks are to be used. In this article we argue that the health ...
