Abstract:
The complementation test with feedback is described as a method for the assessment of disturbances of volume-pressure compensation. The method is characterized by changing infusion rate and the value of this rate depends on the value of cerebrospinal fluid pressure rise in the test. The infusion is stopped when the relative pressure rise reaches 10 mm Hg. Computer-assisted control of infusion and pressure measurement makes possible achieving of greater accuracy of determination of parameters. The test with feedback was compared with the test with stable infusion rate with regard to the indices characterizing the invasiveness of the method. A statistically significant reduction of this invasiveness was noted.
