The past century has seen improvement in trauma care, with a resulting decrease in therapeutically preventable deaths. We hypothesize that further major reduction in injury mortality will be obtained through injury prevention, rather than improvements in therapy. ⋯ Dramatically improving therapy (no errors, cure for multiple organ failure, sepsis, and pulmonary embolus) in a modern trauma system would decrease trauma mortality by 13%. In contrast, more than half of all deaths are potentially preventable with preinjury behavioral changes. Injury prevention is critical to reducing deaths in the modern trauma system.

Alteration of the postinjury hyperinflammatory response by means of resuscitation with a red cell substitute.
Transfusion of stored packed red blood cells (PRBCs) has unintended effects beyond the desired results of increased oxygen delivery. A particular concern is the potential for lipid and cytokine mediators present in PRBCs to augment the postinjury inflammatory response that sometimes culminates in multiple organ failure. Through the use of a polymerized human hemoglobin (PolyHeme), we have been able to measure the inflammatory response in patients resuscitated with minimal exposure to banked components in the early postinjury period. ⋯ Consistent with concerns about the immunoinflammatory response to transfusion of PRBCs, we observed exaggerated levels of three markers associated with adverse outcome. The clinical significance of these findings with respect to the development of multiple organ failure awaits further study.

Uncertainty about the definition and diagnosis of blunt cardiac injury (BCI) leads to unnecessary hospitalization and cost while trying to rule it out. The purpose of this study was to examine whether the combination of two simple tests, electrocardiography (ECG) and serum troponin I (TnI) level, may serve as reliable predictors of BCI or the absence of it. ⋯ The combination of normal ECG and TnI at admission and 8 hours later rules out the diagnosis of SigBCI. In the absence of other reasons for hospitalization, such patients can be safely discharged.

We describe the surgical response of two affiliated hospitals during the day of, and week following, the September 11th, 2001 terrorist attack at the World Trade Center in New York City. The city of New York has 18 state designated regional trauma centers that receive major trauma victims. The southern half of Manhattan is served by a burn center, two regional trauma centers, and a community hospital that is an affiliate of one of the regional trauma centers. This report accounts for the surgical response by a regional trauma center (Hospital A, located 2.5 miles from the World Trade Center) and its affiliate hospital (Hospital B, located 5 city blocks from the World Trade Center) on September 11th when two commercial jets crashed into the Twin Towers at the World Trade Center mall. ⋯ The September 11th, 2001, terrorist attack in New York City, involving two commercial airliners crashing into the World Trade Center, led to 911 patients received at two affiliated hospitals in lower Manhattan. One hospital is a regional trauma center and one was an affiliate community hospital. Eighty five percent of the patients received were walking wounded. Of the rest, 13% underwent surgical procedures with an overall critical mortality rate of 37.5%.

Polymorphonuclear leukocyte (PMNL)-derived microparticles (MPs) have been recently reported as activators of vascular endothelium in vitro. The objectives of the present study were to evaluate the production of MPs in severely injured patients and to clarify the role of these MPs. ⋯ Activated PMNLs enhance production of PMNL-derived MPs with increased adhesion molecule expression on days 2 to 5 after severe trauma. This response per se, however, may not progress to systemic vascular endothelial damage.
