Identifying hypoperfusion in hypothermic trauma patients.

Hypothermia in severely injured trauma patients brings its own risks to an already serious situation¹. The combination of hypothermia with acidosis and coagulopathy, known as the “deadly triad”, is associated with imminent mortality in the severely injured trauma patient.

On May 5,2008, Greg Beilman MD, Professor of Surgery and Anesthesiology, Chief of Surgical Critical Care at the University of Minnesota presented a webinar discussing Hypothermia's relationship to mortality and MODS and the utility of InSpectra StO₂ as a measure of hypoperfusion.

The InSpectra™ StO₂ Tissue Oxygenation Monitor provides a noninvasive, continuous, real-time, and direct measurement of hemoglobin oxygen saturation in tissue (StO₂), providing trauma teams the ability to measure tissue oxygen saturation and monitor it during resuscitation. It is the only perfusion status monitor designed for trauma environments. The InSpectra StO₂ Tissue Oxygenation Monitor uses near infrared light to illuminate tissue, and then analyzes the returned light to produce a quantitative measurement of oxygen saturation in the tissue's microcirculation.

The StO₂ Trauma Study researched the role that tissue oxygen saturation monitoring could play in hemorrhagic shock and resuscitation. Study results demonstrate that StO₂ measurements less than 75% may indicate serious hypoperfusion in trauma patients and that StO₂ functions as well as base deficit in indicating hypoperfusion in trauma patients.
