%X These observations were performed on patients presenting to the 228th CSH, Co B, at Forward Operating Base Speicher, outside of Tikrit, Iraq, between the dates of June 15 and September 11, 2005. We utilized the Inspectra£¿ 325 tissue oxygen saturation (StO2) monitor (Hutchinson Technology, Inc; Hutchinson, MN, USA) with the probe placed on the thenar eminence or on another appropriate muscle bed, and used to monitor StO2 during early resuscitation and stabilization of patients.During the above time period, 161 patients were evaluated at the CSH as a result of traumatic injury and the device was placed on approximately 40 patients. In most patients, StO2 readings of greater than 70% were noted during the initial evaluation. No further information was collected from these patients. In 8 patients, convenience samples of StO2 data were collected along with pertinent physiologic data. In these patients, StO2 levels of below 70% tracked with hypotension, tachycardia, and clinical shock resulted in increases in StO2 after resuscitation maneuvers.Near-infrared spectroscopy-derived StO2 reflected and tracked the resuscitation status of our patients with battlefield injuries. StO2 has significant potential for use in resuscitation and care of patients with battlefield injuries.Optimal treatment for early hemorrhagic shock includes adequate control of bleeding followed by restoration of tissue oxygen delivery with appropriate resuscitation. Unfortunately, from a military perspective, this optimal strategy may not be available for many patients due to field situations that preclude prompt transport to the appropriate treatment facility [1]. Therefore, determination of the magnitude of shock using a rapid, non-invasive method may be useful at the point of care in the field in both military and urban trauma settings. Such a method has the potential to be of use for appropriate triage depending on availability of medical resources.Near-infrared (NIR) spectroscopy utilizes fiber-opt
