[Changes in some plasma parameters in the course of dextran 40].
Changes in certainplasma parameters (Hc, arterial and venous VP, creatinine clearance, potassium, PA and FC) induced by Dextran 40 perfusions (500 ml at 40 drops/min and 250 ml at 20 drops/min) were examined in 50 patients.  The expander effect was more intense, though less protracted when the larger quantity was used.  A rebound effect 24 hr after the test was also more frequent percentage-wise in this group.  Significant changes in Hc were not observed for 24 hr and 96 hr respectively with the higher and the lower dose.  The venous district was primarily concerned.  There were also increases in blood potassium, FC and max PA, while min PA and blood proteins fell.  No relation could be demonstrated between creatinine clearance and diuresis at the end of the test with respect to the amount of Dextran employed.  None of these latter modifications was significant.  There were no signs of intolerance.
