To determine the utility of near-infrared spectroscopy in the diagnosis of lower extremity compartment syndrome (CS). ⋯ Near-infrared spectroscopy-derived StO2 values in the lower extremities of trauma patients with CS were diminished relative to the control patients and usually normalized after fasciotomy. Near-infrared spectroscopy evaluation may offer a rapid, noninvasive method of assessing extremities at risk for CS.

To compare the hemostatic capabilities of poly-Nacetylglucosamine (p-GlcNAc) with three currently available products: Actifoam, Surgicel, and Bolheal fibrin glue. This study was conducted in a controlled animal model, with monitoring of hematologic parameters over the course of the study. Two series were conducted, one in unheparinized animals comparing Bolheal fibrin sealant, Actifoam (absorbable collagen, AC), and Surgicel (ORC) with p-GlcNAc, and the second in systemically heparinized animals comparing p-GlcNAc with AC. ⋯ The results of the previous series in unheparinized animals demonstrated that p-GlcNAc in the form of a membrane is a more effective topical hemostatic agent than Bolheal fibrin glue, AC or ORC. The results in the anticoagulated animals similarly demonstrate that p-GlcNAc is a more effective topical hemostatic agent than the control material AC. These data indicate that p-GlcNAc is a promising hemostatic agent as evaluated in this model.

Because of the need to improve the quality of care of trauma patients in our country, we decided to evaluate the epidemiology and find the most powerful tool for prediction of survival. The Trauma and Injury Severity Score (TRISS) has been known as conventional method for this purpose. We planned to test its ability for prediction of survival of our trauma patients, and also we wanted to compare its ability with the New Injury Severity Score (NISS) in combination with Revised Trauma Score (RTS) and age. We used the most suitable model to evaluate the trauma care in our centers. ⋯ Based on our descriptive findings, we proposed some suggestions that seem to be necessary for improvement of trauma care in our centers. Among them were improved measures for prehospital service, and emergency department and other health care units of our centers. The findings of this study suggest that conducting trauma surgery training programs and direct transportation to trauma centers can improve the outcome of trauma patients. We conclude that small sample size, mixing penetrating trauma cases with blunt trauma cases, and differences in the mechanism of trauma between study populations may be responsible for the difference between our results and others.

Limb salvage for chronic tibial osteomyelitis: an outcomes study.
The decision to undergo a limb salvage procedure is difficult and multifaceted. This study reviews the outcomes of patients with chronic tibial osteomyelitis who underwent limb salvage and hopes to enhance our understanding of the impact this complex procedure has on the patient's ability to have a functional and fulfilling life. ⋯ Limb salvage seems to be a satisfactory option for patients with chronic tibial osteomyelitis. A history of smoking and advanced age may have adverse affects and are relative contraindications.

The circumstances of failure for nonoperative management of blunt traumatic brain injury have been poorly defined. In this study, all trauma patients identified over a 12-year period with progression of neurologic injury requiring craniotomy were retrospectively reviewed. ⋯ Of the variables investigated, only anatomic location of injury was found to be predictive of early failure of nonoperative management. Frontal intraparenchymal hematomas are particularly prone to early failure. Clinical examination and intracranial pressure monitoring are equally important in detecting failure and should be an integral part of nonoperative management.
