Clinical Trial Summary
ScvO2 is an important parameter in the management of critically ill patient. The only way to
measure it is to have an internal jugular or subclavian central venous catheter. With this
trial, the investigators want to show a positive relationship between invasive ScvO2
measurement and noninvasive SjvO2 measurement with VO 100 medical device from Mespere
LifeSciences, allowing the use of SjvO2 as a noninvasive surrogate of ScvO2 in critically ill
patients.
Description:
ScvO2 measures central venous oxygen saturation level from veins draining the head and upper
body while SvO2 measures mixed venous oxygen saturation from the lower and upper half of the
body. ScvO2 is more conveniently measured and less risky than Sv02 measurement although a
central venous catheter is needed. ScvO2 gives knowledge about the balance between the
delivery of oxygen and oxygen consumption in the body. Interest in ScvO2 monitoring in
anesthesia and critical care has been debated. However, ScvO2 is still recommended as a major
hemodynamic target of early resuscitation of critically ill patients. Even if ScvO2
measurement is far less invasive than SvO2 measurement through pulmonary artery catheter, it
is accompanied with morbidity.
VO 100 medical device from Mespere LifeSciences allows a non-invasive measurement of SjvO2
using the NIRS technique. Jugular venous oxygen saturation (SjvO2) is a measurement of the
amount of oxygen left in the venous system after the brain has removed the oxygen that it
needs.
On the same principle that a positive relationship between ScvO2 and SvO2 has been shown,
what the investigators are trying to do is to show a positive relationship between SjvO2 and
ScvO2 in order to possibly use in the future SjvO2 measured by VO 100 as a noninvasive
surrogate of ScvO2.
