Thrombotest Dilution Curve

Thrombotest dilution curve.

Initial Experience with Thrombotest.

The initial experience of using Thrombotest instead of Quick's one-stage prothrombin time to control anticoagulant therapy is described.Patients well controlled by the Quick test are often found to be over-anticoagulated by Thrombotest standards, so the introduction of Thrombotest has led to widespread reductions in dosage. No improvement in stability of control has been noted. The main advanta...

Modeling the myocardial dilution curve of a pure intravascular indicator.

The dispersion and dilution of contrast medium through the myocardial vasculature is examined first with a serial model comprised of arterial, capillary, and venous components in series to determine their time-concentration curves (TCC) and the myocardial dilution curve (MDC). Analysis of general characteristics shows that the first moment of the MDC, adjusted for that of the aortic TCC and mea...

Detection of bronchial blood flow from earpiece dye-dilution curve.

In an attempt to detect an increased bronchial blood flow in man from the earpiece dye-dilution curve, the reliability of three indexes was investigated by comparing them with the values of bronchial blood flow measured from the left atrial dye-dilution curve following dye injection into the aortic root. The first index is obtained from the Cp method, in which the ratio of the peak concentratio...

Thrombotest Values in Low Birthweight Infants

Appleyard, W. J., and Cottom, D. G. (1970). Archives of Disease in Childhood, 45, 705. Effect of asphyxia on thrombotest values in low birthweight infants. Thrombotest was used as a measure of coagulation status in 55 low birthweight infants. The initial levels were similar in both babies who were asphyxiated at birth and in those who had uncomplicated deliveries. On the other hand, 24 hours af...
