Experimentation involving human subjects requires careful attention to the protection of their rights. Beginning with the Belmont Report in 1979, the United States has developed various sets of rules and regulations that identify the requirements for performing human subject research. In addition, these standards attempt to define the fundamental difference between what constitutes research versus clinical treatment versus innovation. We explore the intersection between two areas of independent bioethics, surgical innovation and emergency research; the point we refer to as emergency innovation. ⋯ For emergency innovation, where it is unclear what ethical principles and regulatory powers apply, it is imperative to be unambiguous about the purpose of the investigation, to adhere to all applicable ethical principles, and to have utmost consideration for protection of the research subject. To determine intent, the goals of the study must be outlined precisely - and if those include the prospect of publication, institutional review board (IRB) approval should be involved early. If, however, the innovation is subtle and the goal geared toward improved patient care, a small feasibility trial would be an appropriate first step before transitioning to a formal larger study approved by an IRB. In either case, the degree of the change in practice must be carefully evaluated and the vulnerability of the research subjects respected. With careful attention paid to all applicable ethical principles at the emergency innovation intersection, medical progress can continue at minimized risk to the human subject participants.

Comparative Study
Comparison of the plasma volume-expanding effects of 6% dextran 70, 5% albumin, and 6% HES 130/0.4 after hemorrhage in the guinea pig.
We still lack comparing data of the plasma volume (PV)-expanding effect of the most commonly used colloids including dextran 70. This study compares the PV-expanding effects of 6% dextran 70, 5% albumin, and 6% hydroxyethylstarch (HES) 130/0.4 after a standardized hemorrhage. ⋯ After hemorrhage, the PV-expanding capacity of 6% dextran 70 was better than that of 5% albumin, which was in turn better than that of HES 130/0.4 given in equal volumes.

Mechanically ventilated trauma patients have a high risk for the development of ventilator-associated pneumonia (VAP). We have recently reported that reduced plasma protein C (PC) levels early after trauma/shock are associated with coagulopathy and mortality. Furthermore, trauma patients with tissue injury and shock are at higher risk for the development of VAP. ⋯ Critically ill trauma patients have an early activation of the PC pathway, associated with a rapid decrease in the plasma levels of this protein and increase in EPCR. Plasma levels of PC return to normal levels within 24 hours in most patients. However, patients who go on to acquire VAP have persistently low plasma levels of PC in the immediate period after trauma. Whether PC could play a mechanistic role in the host response against nosocomial lung infection warrants further study.

The objective of this study was to survey Trauma Center (TC) members of the National Foundation for Trauma Care/Trauma Center Association of America to determine usage and consistency of trauma team response charge codes and critical care accommodation charges for severely injured patients. Potential over- and underutilization of these enhanced reimbursements was assessed. ⋯ Significant underused opportunities exist for enhanced revenue by improved implementation of trauma response codes. Wide ranges in charges and the low frequency of full implementation suggest that education and coordination are needed among hospital departments involved, as well as among the trauma care community at large, to realize optimal reimbursement for trauma care services.
