Comparative Study
Effectiveness of helicopter versus ground ambulance services for interfacility transport.
Helicopters provide rapid interfacility transport, but the effect on patients is largely unknown. ⋯ The patients transported by helicopter did not have improved outcomes compared with patients transported by ground. These data argue against a large advantage of helicopters for interfacility transport. A randomized trial is needed to address these issues conclusively.

Case Reports
Delayed hemothorax after blunt thoracic trauma: an uncommon entity with significant morbidity.
To describe the nature of delayed hemothorax occurring after blunt thoracic trauma and to identify the population at risk for this complication. ⋯ Delayed hemothorax after blunt trauma is a unique entity occurring in patients with multiple or displaced rib fractures. Vigilance for the recognizable prodrome in the high-risk population should allow early remediation of this complication.

Changes in the management of torso gunshot wounds (TGSWs) have evolved in recent years as a result of differences between military and civilian injuries and increasing interest in avoiding nontherapeutic invasive procedures. The objective of this study was to establish the utility and accuracy of computed tomography (CT) in the evaluation of selected patients with TGSWs. ⋯ CT of selected TGSW patients is safe and may reduce the incidence of invasive diagnostic procedures. A prospective evaluation of CT for TGSW patients is warranted.

Previous series of traumatic amputations have noted that delay in amputation results in prolonged hospital stay and delayed rehabilitation. A series of major extremity amputations after burn injury was analyzed to identify the frequency of delayed amputation and to identify factors resulting in the delay. ⋯ There is a bimodal distribution of time to amputation determined by mechanism of injury, severity of burn, and infectious complications. Earlier identification of nonsalvageable limbs may decrease infectious complications and improve the chances of patient survival.

Hypothermia is considered harmful in trauma patients. In surgery, hypothermia is occasionally used to reduce metabolism and protect the brain. Recent studies in animals have also shown protective effects of hypothermia in hemorrhagic shock. The aim of this study was to evaluate the metabolic and endocrine effects of induced hypothermia in hemorrhagic shock. ⋯ In porcine hemorrhagic shock, induced hypothermia increases arterial oxygen tension and stabilizes serum levels of potassium and catecholamines.
