Study Summary

This trial is testing if non-invasive methods are as good as the current gold standard for detecting changes in fluid volume. It is split into two studies, with the first study being a pilot to develop the non-invasive techniques.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Aim 1Experimental Treatment1 Intervention
The ethanol dilution is, in essence, a non-invasive dilution method. It is of interest because of how ethanol readily dissolves itself exclusively into the water space of the body[4], is non-toxic in reasonable concentrations, is metabolized in a 0th order reaction above concentrations of 0.015 g/dL[4], and there are non-invasive methods for determining blood alcohol concentration[5, 6]. Thus, by drinking a known amount of ethanol, total body water can be calculated after a few hours of periodic breathalyzer analyses. Ethanol has been validated against deuterium oxide, the invasive gold standard for determining total body water[4]. The ethanol dose will be 0.5g/kg body weight.
Group II: Aim 2Active Control1 Intervention
30mL/kg body weight of saline will be rapidly infused after the baseline measurements completed in Aim 1. Non-invasive methods for fluid volume determination (CO-pulse-oximetry, ethanol breathalyzer, BIS) will be conducted and change from baseline calculated.
