Summary

Patients with severe infections initially require large amounts of fluid as part of resuscitation. Later on however, problems may arise from excess fluid such as increased time on a ventilator and kidney damage. The amount of fluid a patient has is difficult to assess. One approach is to determine the amount of fluid that is present in a large central vein. This can be done by physical examination of the jugular veins, or by placing a catheter within the vein. Unfortunately this method is unreliable and does not predict the amount of fluid a patient has.

Bioimpedance analysis (BIA), is a device that can determine the amount of fluid in the body by measuring the body's electrical properties. It is a quick and painless test that assesses volume. The primary objective of this study is to determine if BIA measurements are associated with patient important outcomes such as time on a ventilator, risk of kidney failure requiring dialysis and death. We will also determine whether BIA is a measure of fluid status in ICU patients. This study will assess feasibility in establishing a multi-centre study assessing if BIA's role in predicting adverse outcomes and thereby prognosis and fluid status. We hypothesize that shorter vector lengths will be associated with hypervolemia and less ventilator free days.

Bioelectric Impedance Analysis

Bioimpedance devices are compact, portable, easy to use, relatively inexpensive and can be used to make repeated non-invasive measurements. Bioimpedance measures the impedance to the flow of an electric current through body fluids and consists of two components, resistance and reactance. Resistance is a measure of electrical current a substance will oppose and is inversely related to tissue fluid content. Reactance is the capacitative component of impedance and indicates energy stored by cell membranes and organelles; due to this property, reactance is associated with tissue cell mass. These raw measures provide a measure of volume as determined by vector length and the RXc graph method.
