Hemorrhagic shock can lead to multiple organ failure and death. We have previously shown that noninvasive measurement of tissue oxygen saturation (StO(2)) has predictive value for outcomes in patients suffering hemorrhagic shock. Our study objectives were twofold: (1) to compare invasive and noninvasive measurements of local and systemic tissue hemoglobin oxygenation and (2) to compare the effects of various physiologic conditions seen in patients in hemorrhagic shock on tissue hemoglobin oxygenation. ⋯ Noninvasive StO(2) measurements are valid and durable over a wide range of physiologic conditions and correlate with invasively-measured oxygen delivery.

Traumatic craniocervical dissociation (CCD), which includes atlanto-occipital dissociation and vertical distraction between C1-C2, is often an immediately fatal injury that has increasingly been associated with survival to the hospital. Our aim was to identify survivors of CCD based on clinical presentation. ⋯ Trauma patients diagnosed with CCD in the ED, with cervical cord injury, requiring CPR, and with GCS of 3 will not survive their injury. Wider BDI is associated with mortality.
