The use of open abdomen techniques in damage control laparotomy and abdominal compartment syndrome has led to development of several methods of temporary abdominal closure. All of these methods require creation of a planned hernia with later reconstruction in patients unable to undergo fascial closure in the early postoperative period. We review a method of late primary fascial closure, thus eliminating the need for delayed reconstruction in some patients. ⋯ VAFC enables late fascial closure in open abdomen patients up to a month after initial laparotomy. Complication rates do not differ from patients with planned hernia, and the need for future abdominal wall reconstruction is avoided.

Hemorrhagic shock (HS) is associated with the generation of reactive oxygen species, which may contribute to delayed multiple organ system failure and death. Previous studies have shown that the antioxidant Tempol improved physiologic variables, although not necessarily outcome, in septic shock and HS. We hypothesized that the combination of free Tempol with polynitroxylated albumin (PNA)-bound Tempol (which prolongs half-life and decreases toxicity) improves outcome after HS in rats. ⋯ When infused early in HS, PNA + Tempol can increase survival. When given late, it significantly improves acid-base and serum antioxidant status, without an effect on survival. Additional studies will be required to determine whether early resuscitation with PNA + Tempol attenuates reactive oxygen species-mediated injury as the mechanism for preventing the progression toward multiple organ failure and death after HS. The results suggest that antioxidant therapy with Tempol deserves further study as a potential adjunct in the initial resuscitation from HS.

The importance of psychological morbidity after major trauma, such as posttraumatic stress disorder (PTSD), is continuing to gain attention in trauma outcomes research. The Trauma Recovery Project is a large prospective epidemiologic study designed to examine multiple outcomes after major trauma, including quality of life (QoL) and PTSD. Patient outcomes were assessed at discharge and at 6, 12, and 18 months after discharge. The specific objectives of the present report are to examine gender differences in prolonged PTSD (L-PTSD) and to assess the impact of PTSD by gender on QoL at the 6-, 12-, and 18-month follow-up time points in the Trauma Recovery Project population. ⋯ These results provide important new evidence that high rates of PTSD persist in the long-term aftermath of major trauma. The association of gender with PTSD was independent of mechanism and injury event-related factors such as perceived threat to life. Within categories of specific mechanism of injury and injury event-related factors, women were at significantly higher risk of prolonged PTSD onset. Prolonged PTSD was associated with significantly reduced quality of life in both men and women, with markedly worse QWB outcomes in women regardless of prolonged PTSD status.

Continuing controversy surrounding the value of scene helicopter evacuation of urban trauma victims led to the present study. ⋯ The helicopter is used excessively for scene transport of trauma victims in our metropolitan trauma system. New criteria should be developed for helicopter deployment in the urban trauma environment.
