Abstract
Hydroxyethyl starch (H. E. S) is a new plasma expander which is developed from starch. In order to assess its clinical evaluation, we employed 30 cases for H. E. S and 10 cases for daily used low molecular dextran as a control.
Before and after the administration of these fluid, electrolytes in urine, electrolytes in blood, BUN, blood sugar and hematocrit at finger tip were measured in patients under general anesthesia. As muscle relaxant, S. C. C. and Dialferin were used.
Statistically significant differences were observed in urine Na (in Dialferin cases), in urine K (in S. C. C. cases), in Na/K (in Dialferin cases), in BUN (in Dialferin cases), in blood sugar (in S. C. C. cases) and in hematocrit (in Dialferin cases).
In conclusion, our study shows no significant, noteworthy, clinical 'differences between H. E. S and low molecular dextrran, although a little differences were occured by two kinds of muscle relaxants.
