Ever-increasing numbers of in-house acute care surgeons and competition for operating room time during normal daytime business hours have led to an increased frequency of nonemergent general and vascular surgery procedures occurring at night when there are fewer residents, consultants, nurses, and support staff available for assistance. This investigation tests the hypothesis that patients undergoing such procedures after hours are at increased risk for postoperative morbidity and mortality. ⋯ Patients undergoing nonemergent general and vascular surgery procedures at night in an academic medical center do not seem to be at increased risk for postoperative morbidity or mortality. Performing nonemergent procedures at night seems to be a safe solution for daytime overcrowding of operating rooms.

It remains to be determined whether spine-targeted computed tomography (thoracolumbar spine computed tomography [TLS-CT]) images and visceral organ-targeted CT (abdominopelvic [AP]-CT) images are comparable for the evaluation of thoracolumbar spinal fractures using 16-channel multidetector row CT. The elimination of an additional spine-targeted CT protocol would substantially reduce time, the storage burden, and potential patient radiation exposure. ⋯ Sixteen-channel multidetector row CT images reconstructed using a soft algorithm and a wide display FOV that cover the entire abdomen using a visceral organ-targeted protocol with 1.5-mm collimation are sufficient for the evaluation of spine fractures in trauma patients, given that multiplanar-reformatted images are provided.

Long-duration blasts are an increasing threat with the expanded use of thermobaric and other novel explosives. Other potential long-duration threats include large explosions from improvised explosive devices, weapons caches, and other explosives including nuclear explosives. However, there are very few long-duration pulmonary blast injury assessments, and use of short-duration exposure injury metrics is inappropriate as the injury mechanism for long-duration exposures is likely different from that of short-duration exposures. ⋯ New injury risk assessment curves were determined for both incident and reflected pressure conditions for reflecting surface and free-field exposures. Position dependent injury risk curves were also determined. The resulting curves are an improvement to existing assessments, because they use actual data to demonstrate theoretical assumptions on the injury risk.

Comparative Study
Risk of mortality: the relationship with associated injuries and fracture treatment methods in patients with unilateral or bilateral femoral shaft fractures.
The aim of the study was to determine the relative contributions to mortality of a unilateral or a bilateral femoral fracture in patients with or without injuries to other body regions. ⋯ The increase in mortality with BFs is more closely associated with the presence of associated injuries and poor physiologic parameters than with the presence of the BF alone. The presence of BFs should alert the clinician to the very high likelihood (80%) of significant associated injuries in other body systems and their life-threatening potential. Damage control fixation options should be considered in the subgroup with a very high New Injury Severity Score.

To investigate the association between a number of hospital level composite index methodologies developed from trauma indicators with inhospital mortality. ⋯ Trauma composite indices demonstrate construct validity when used as measures of hospital level process and represent potentially useful methods of analyzing and reporting quality indicators.
