Aggressive screening for blunt cerebrovascular injury (BCVI) has uncovered an astonishing incidence of vertebral artery injuries (VAIs) and associated stroke rate. Stroke incidence is reduced with early recognition and prompt anticoagulation. Because of the proximity of the cervical spine and vertebral arteries, we queried whether all patients with cervical spine fractures required arteriography to rule out VAI. ⋯ Blunt vertebral artery injury is associated with complex cervical spine fractures involving subluxation, extension into the foramen transversarium, or upper C1 to C3 fractures. Routine screening should incorporate these findings to maximize yield while limiting the use of invasive procedures.

Blunt injury to the colon is rare. Few studies of adequate size and design exist to allow clinically useful conclusions. The Eastern Association for the Surgery of Trauma Multi-institutional Hollow Viscus Injury (HVI) Study presents a unique opportunity to definitively study these injuries. ⋯ Colonic injury after blunt trauma is rare and difficult to diagnose. No diagnostic test or combination of findings reliably excluded blunt colonic injury. Despite the inadequacy of current diagnostic tests, almost all patients with colonic injury were taken to the operating room within 24 hours. Even with relatively prompt surgery, patients with colon injury were at significantly higher risk for serious complications and increased length of stay. In contrast to small bowel perforation, delay in operative intervention appears to be less common but is still associated with serious morbidity.

The gradient of end-tidal CO2 to arterial CO2 (Pa-ET)CO2 has been identified as a predictor of mortality in patients undergoing emergency trauma surgery. In an effort to further elucidate this phenomena, we accumulated additional data on trauma patients undergoing emergency surgery. ⋯ (Pa-ET)CO2 can be used as a predictor of mortality and may be useful as an intraoperative tool for assessing the physiologic conditions of the patient. This predictor of mortality was valid even in patients that died greater than 24 hours after surgery. This information is almost always already available and may be used to further guide the decisions regarding patient care, particularly in decisions regarding damage control surgery.
