The TRISS methodology (composite index of the Revised Trauma Score and the Injury Severity Score) has become widely used by trauma centers to assess quality of care. The American College of Surgeons recommends including negative TRISS fallouts (fatally injured patients predicted to survive by the TRISS methodology) as a filter to select patients for peer review. The purpose of this study was to analyze the TRISS fallouts among patients with lethal abdominal gunshot wounds admitted to a level I trauma center. ⋯ "TRISS fallouts" were predominantly patients who died despite receiving rapid prehospital transport, rapid senior-level trauma-team response, and surgical intervention for a serious complex of injuries. We conclude that without regional adjustment of coefficients used to predict the probability of survival, the TRISS methodology is of limited use in patients with abdominal gunshot wounds.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
The first randomized trial of human polymerized hemoglobin as a blood substitute in acute trauma and emergent surgery.
Human polymerized hemoglobin (PolyHeme) is a universally compatible, disease-free, oxygen-carrying resuscitative fluid. This is the first prospective, randomized trial to compare directly the therapeutic benefit of PolyHeme with that of allogeneic red blood cells (RBCs) in the treatment of acute blood loss. ⋯ PolyHeme is safe in acute blood loss, maintains total [Hb] in lieu of red cells despite the marked fall in RBC [Hb], and reduces the use of allogeneic blood. PolyHeme appears to be a clinically useful blood substitute.

The aim of operative chest wall stabilization in patients with flail chest and respiratory insufficiency is to reduce ventilator time and avoid ventilator associated complications. The purpose of this retrospective study was to analyze the indications and outcomes of operative chest wall stabilization in defined groups of patients sustaining flail chest with and without pulmonary contusion. ⋯ In patients with flail chest and respiratory insufficiency without pulmonary contusion, operative chest wall stabilization permits early extubation. Patients with pulmonary contusion do not benefit from chest wall stabilization. Secondary operative chest wall stabilization in these patients is indicated when progressive collapse of the chest wall is evident during weaning from the ventilator.
