Management of the open abdomen in trauma and nontrauma patients is difficult, and some areas of controversy remain. Gastrointestinal fistulas are serious complications that are associated with significant mortality. We present our method for management of patients with open abdomen and also present a logical technique of subsequent repair of the late giant ventral hernias that uniformly occur in these patients. ⋯ Immediate closure of the open abdomen with bilateral bipedicle anterior abdominal skin flaps is an effective technique for dealing with such potentially complicated problems. Management of late giant ventral hernias with retrorectus prosthetic mesh repair is theoretically reasonable and, so far, no recurrence has been observed in our patients.

A study was performed to demonstrate that slower respiratory rates (RRs) of positive-pressure ventilation can preserve adequate oxygenation and acid-base status in hemorrhagic states, whereas "normal" or higher RRs worsen hemodynamics. ⋯ After even moderate levels of hemorrhage in animals, positive-pressure ventilation with "normal" or higher RRs can impair hemodynamics. Hemodynamics can be improved with lower RRs while still maintaining adequate oxygenation and ventilation.

Traumatic combat injuries differ from those encountered in the civilian setting in terms of epidemiology, mechanism of wounding, pathophysiologic trajectory after injury, and outcome. Except for a few notable exceptions, data sources for combat injuries have historically been inadequate. Although the pathophysiologic process of dying is the same (i.e., dominated by exsanguination and central nervous system injury) in both the civilian and military arenas, combat trauma has unique considerations with regard to acute resuscitation, including (1) the high energy and high lethality of wounding agents; (2) multiple causes of wounding; (3) preponderance of penetrating injury; (4) persistence of threat in tactical settings; (5) austere, resource-constrained environment; and (5) delayed access to definitive care. Recognition of these differences can help bring focus to resuscitation research for combat settings and can serve to foster greater civilian-military collaboration in both basic and transitional research.
