Abstract
Norepinephrine (NE), epinephrine (EPI), and dopamine (DA) were determined in the blood
plasma of 122 subjects by high-performance liquid chromatography with amperometric
detection (HPLCA). The range of normal values in the supine position was 0.15-3.50
nmol/1 for NE, 0.01-0.80 nmol/1 for EPI, and 0.04-4.50 nmol/1 for DA. The effect induced
by inserting intravenous catheters, food intake, cigarette smoking, varying body positions,
and sex differences are also presented in this paper.
As a modified HPLCA method was used, we were able to examine a large collective group.
Thus, it was possible to compare the results of other authors which have been found
in smaller collective groups.
