Abstract: An investigation was conducted in order to determine whether water immersion to the neck (NI) alters plasma catecholamines in normal humans. Eight normal subjects were studied during a seated control study (C) and during 4 hr of NI, and the levels of norepinephrine (NE) and epinephrine (E) as determined by radioenzymatic assay were measured hourly. Results show that despite the induction of a marked natriuresis and diuresis indicating significant central hypervolemia, NI failed to alter plasma NE or E levels compared with those of either C or the corresponding prestudy 1.5 hr. In addition, the diuresis and natriuresis was found to vary independently of NE. These results indicate that the response of the sympathetic nervous system to acute volume alteration may differ from the reported response to chronic volume expansion.
