Optimal timing of femur fracture fixation remains controversial. This study examines the association between the timing of femur fracture fixation and outcome in patients with concomitant chest and head injuries. ⋯ Our data show that early femur fracture fixation (< 24 hours) is associated with an improved outcome, even in patients with coexistent head and/or chest trauma. Fixation of femur fractures at 2 to 5 days was associated with a significant increase in pulmonary complications, particularly with concomitant head or chest trauma, and length of stay. Chest and head trauma are not contraindications to early fixation with reamed intramedullary nailing.

Multicenter Study Comparative Study
Motor vehicle restraints: primary versus secondary enforcement and ethnicity.
Efforts to increase motor vehicle restraint use have been broadly based rather than focused on specific populations. Identifying specific issues, including populations with low restraint use, can help target educational campaigns. Previous studies have reported differences in restraint use by ethnicity. This study was performed to determine whether differences exist in motor vehicle restraint use by ethnicity and whether these differences are altered by the presence of primary versus secondary restraint laws. ⋯ In a state with secondary enforcement laws, restraint use varied significantly with ethnicity. Restraint use was markedly increased in all ethnic groups by the presence of a primary enforcement law. Implementation and enforcement of primary restraint laws is essential to improving motor vehicle restraint use. Educational campaigns to increase restraint use need to target specific populations.

Knee dislocation, which poses a significant risk for injury of the popliteal artery, prompts many surgeons to evaluate these patients with arteriography routinely. Our hypothesis was that physical examination alone (without arteriography) accurately confirms or excludes surgically significant vascular injuries associated with knee dislocation. ⋯ This limited series suggests that the presence or absence of an injury of the popliteal artery after knee dislocation can be safely and reliably predicted, with a 94.3% positive predictive value and 100% negative predictive value. Arteriography appears to be unnecessary when physical examination is negative but may avert negative vascular exploration when physical examination is positive. This approach substantially reduces cost and resource use without adverse impact on the patient.

Brain injury as well as early inflammatory and endocrine responses were found to be indicators for infectious complications in patients with multiple injuries. In this context, brain-derived inflammatory response as well as centrally triggered neuroendocrine activation and systemic immunodepression seem to be of major importance. Therefore, we hypothesize that a circulating index of inflammatory or endocrine function measured soon after brain injury (in patients with admission Glasgow Coma Scale [GCS] score of 4-7) would discriminate severe from moderate injury as indexed by GCS status on postinjury day 7. ⋯ The IL-6 plasma level 1 day after the acute event with a cut-off of 100 pg/mL (Immulite) seems to be a predictor for short-term prognosis and infectious complications in brain-injured patients.

Echocardiography has been shown to be valuable in critically ill surgical patients. Transthoracic echocardiography (TTE) often fails to provide adequate imaging in critically ill patients, necessitating subsequent transesophageal echocardiography (TEE). The objective of this study was to determine and quantify factors associated with failure of transthoracic echocardiography (TTE) in critically ill surgical patients, and to define a cost-effective strategy for echocardiography in these patients. ⋯ The routine use of TTE to initially evaluate all critically ill surgical patients who require echocardiography should be abandoned because it is not cost-effective. TEE appears to be the most cost-effective echocardiographic modality in the surgical intensive care unit.
