Comparative Study
Rectal pH measurement in tracking cardiac performance in a hemorrhagic shock model.
We evaluated the utility of rectal mucosal pH measurement for tracking cardiac performance in hemorrhagic shock as compared with gastric tonometry. ⋯ Rectal mucosal pH tracks cardiac performance as well as does gastric tonometry in hemorrhagic shock without as many limitations.

Comparative Study Clinical Trial
Emergent abdominal sonography as a screening test in a new diagnostic algorithm for blunt trauma.
Although there is an interest in emergent abdominal sonography (EAS), the clinical utilization of EAS in North America is minimal. The purpose of this study was to develop a new diagnostic algorithm for blunt abdominal injury based on a prospective blinded comparison of EAS, diagnostic peritoneal lavage (DPL), and computed tomography (CT). EAS (+ = fluid, - = no fluid) was performed before the DPL or CT, in 400 patients with a mean Injury Severity Score of 26; 293 had a CT and 107 had a DPL. ⋯ Based on these results, a diagnostic algorithm was developed using EAS as a screening test with selective use of DPL and CT. Emergent abdominal sonography performed by clinician sonographers is a rapid and accurate test for peritoneal fluid in blunt trauma victims, and the need for laparotomy in patients with a negative EAS is rare. Our study supports the routine use of EAS as a screening test in a diagnostic algorithm for the evaluation of blunt abdominal trauma.

Comparative Study
Abbreviated Injury Scale does not reflect the added morbidity of multiple lower extremity fractures.
To determine if patients with multiple lower extremity fractures have worse outcomes than do patients with isolated femur fractures, and to determine if the Abbreviated Injury Scale (AIS) should distinguish between single and multiple lower extremity fractures. ⋯ Although AIS and ISS appropriately reflect the impact of extraskeletal injuries in patients with femur fractures, they do not adequately reflect the increased morbidity associated with multiple lower extremity fractures. The AIS-Extremity Score may need to be upgraded for multiple long bone fractures of the lower extremities.

Comparative Study
Predicting the need to pack early for severe intra-abdominal hemorrhage.
To determine if the decision to pack for hemorrhage could be refined. ⋯ Patients who suffer severe injury, hypothermia, refractory hypotension, coagulopathy, and acidosis need early packing if they are to survive. Failure to control hemorrhage is related to severity of injury and delay in the use of pack tamponade. A specific protocol that mandates packing when parameters reach a critical limit should be considered.

Trauma care reimbursement in rural hospitals: implications for triage and trauma system design.
American College of Surgeons triage guidelines recommend rapid identification and transfer of seriously injured patients to regional trauma centers, bypassing local hospitals if necessary. This approach raises concerns about the potential negative financial impact of implementing such triage strategies on already strained rural hospitals. ⋯ The study demonstrates that as injury severity increases, costs and charges increase, but reimbursement does not keep pace with these increased charges. The rural hospital was projected to lose an average of $25,000 for each patient with an Injury Severity Score over 15. This study supports the rapid triage and transport of the seriously injured patient from the rural hospital to the regional trauma center both for improved patient outcome and for the hospital's best interest. The potential impact of such a system on the trauma center also needs to be addressed.
