HEALTHY Clinical Trial
Official title:
Bioimpedance Spectroscopy in Humans During Acute Fluid Volume Expansion With Different Crystalloid Solutions
The objective of the study is to identify a pattern of bioimpedance in humans during acute food changes. As a part of this study the investigators will be administering sodium bromide in oder to measure extracellular water via the bromide dilution technique.
The resistance of the human body to the flow of alternating current is thought to be related
to the volume of fluid within the body. The acute change in fluid status of the human body
alters the body resistance. This change can be measured accurately with bioelectrical
impedance and previous experiments confirmed this observation. However, previous experiments
using a piglet model and subsequently humans, suggested that the changes observed is a result
of changes in salt instead of body water.
An experiment has shown that bioimpedance analysis (BIA) was able to detect changes in total
body resistance when different electrolyte solutions were infused. The changes in resistance
were related to changes in osmolarity and electro-ionic state, not to volume of water
infused. Therefore, BIA measures principally the electro-ionic state. Thus a measurement of
fluid volume can be indirectly obtained from BIA. However, in the non-steady state such as
acute fluid volume expansion, the measurement of water volume cannot be performed accurately.
In this study, we will be administering sodium bromide in oder to measure extracellular water
via the bromide solution technique. Despite the interesting observations, the human study
described above was underpowered. Therefore, we aim to validate the observations that have
been previously made through carrying out an appropriately powered study with an adequate
sample size to validate the observations noted.
