Comparative Study
Biodistribution of indocyanine green in a porcine burn model: light and fluorescence microscopy.
Infrared-excited fluorescence of intravenously administered indocyanine green (ICG) is being used as a method of early determination of burn depth. ⋯ The intensity of ICG fluorescence measured at the surface of the wound for burns of similar age was shown to decrease exponentially with the depth of the burn. The enhanced fluorescence of partial-thickness burns is attributable to increased permeability, and the decreased signal associated with deeper injuries is attributable to vascular occlusion. These results suggest that it is possible to differentiate burns that will heal spontaneously with minimal granulation from those that will not by measuring the intensity of ICG fluorescence.

To determine the value of follow-up abdominal computed tomography in patients with splenic trauma managed nonoperatively. ⋯ Follow-up abdominal CT scans are not routinely necessary in patients with splenic injuries managed nonoperatively.

The purpose of this study was to characterize the geographic epidemiology of serious nonfatal firearm injuries (NFFI) within Pennsylvania during a 6-year period. ⋯ Significant variation in NFFI was observed across population-based regions in Pennsylvania. Rural areas demonstrated relatively high risks of NFFI committed unintentionally, in the home, and with rifles. As regional populations increase, relatively high risks of NFFI, committed as assaults, in the street, and by handguns, are highlighted. Although handguns were the most prominent firearm associated with NFFI, nonfatal shotgun injuries produced substantially longer hospital stays and may be an underappreciated cause of nonfatal firearm assaults in the urban setting.

Definitive trauma team leadership, although difficult to measure, has been shown to improve trauma resuscitation performance. The purpose of this study was to evaluate the effect of an identified command-physician on resuscitation performance. In addition, the leadership capability of four physician combinations functioning as command-physician was studied. ⋯ An identified command-physician enhances trauma resuscitation performance. Completion of the primary and secondary survey is not affected by the physician combination. Prompt formulation of a definitive plan is facilitated by the active involvement of an attending traumatologist or a properly mentored trauma fellow.

The role of plate fixation in the management of fresh displaced midclavicular fractures is unsettled. The objective of this study was to evaluate the drawbacks and pitfalls of this treatment method. ⋯ Patient noncompliance with the postoperative regimen could be suspected to have been a major cause of the failures. The high complication rate supports a reserved attitude toward plate fixation of fresh midclavicular fractures. The method should be reserved for patients who have trustworthy personal motives for quick pain relief and functional recovery.
