Stress-induced alterations in coagulation: assessment of a new hemoconcentration correction technique.
OBJECTIVE For the examination of psychological stress effects on coagulation, the Dill and Costill correction (DCC) for hemoconcentration effects has been used to adjust for stress-induced plasma volume changes. Although the correction is appropriate for adjusting concentrations of various large blood constituents, it may be inappropriate for time-dependent or functional coagulation assays. Two...
متن کاملAlterations in Coagulation Induced by Hypothermia and Acidosis in Swine1
Although clinical coagulopathy is associated with acidosis and hypothermia, the underlying mechanisms by which these factors alter the coagulation process remains unclear. The primary purpose of this study was to investigate the contributory effects of acidosis and hypothermia to the development of coagulopathy. Twentyfour pigs were randomly divided into control (pH 7.4, 39°C), acidotic (pH 7.1...
متن کاملAlterations in the Blood Coagulation System Induced by Bacterial Endotoxins
Bacterial endotoxins in vitro are capable of shortening the coagulation time of normal whole blood, native platelet-rich and platelet-poor plasma, and the blood of a hemophilic patient in silicone but not in glass. The point in the coagulation system at which the endotoxins act has not been found but the search has been narrowed by the demonstration that these materials act independently of leu...
متن کاملAlterations in the Blood Coagulation System Induced by Bacterial Endotoxin
The intravenous injection of bacterial endotoxins alter the coagulation system of rabbits' blood in vivo. Twenty-four hours after the first injection the fibrinogen level rises to twice normal values. The second injection at this time causes a 30 to 40 per cent decrease in fibrinogen content in 4 hours. Twenty hours later it again rises to twice normal values. A marked decrease in whole blood c...
متن کاملComparison of Stress-Hemoconcentration Correction Techniques for Stress-Induced Coagulation
When examining stress effects on coagulation, arithmetic correction is typically used to adjust for concomitant hemoconcentration but may be inappropriate for coagulation activity assays. We examined a new physiologically relevant method of correcting for stress-hemoconcentration. Blood was drawn from healthy men (N = 40) during baseline, mental stress, and recovery, and factor VII activity (FV...
