Angiographic embolization (AE) is used with increasing frequency as an alternative to surgery for control of intraperitoneal and retroperitoneal bleeding. There are no prospective studies on its efficacy, safety, and indications. ⋯ AE is highly effective in controlling bleeding caused by abdominal and pelvic injuries and difficult to manage by surgery. Older age, the absence of long-bone fractures, and emergent angiography increase the likelihood of finding active bleeding angiographically. However, there are no clinical characteristics to exclude reliably all patients who are not actively bleeding internally. Because of this and its reasonable safety profile, AE should be offered liberally in patients with selected injuries of the pelvis and abdominal visceral organs.

Massive transfusion of blood products in trauma patients can acutely deplete the blood bank. It was hypothesized that, despite a large allocation of resources to trauma patients receiving more than 50 units of blood products in the first 24 hours, outcome data would support the continued practice of massive transfusion. ⋯ The 43% survival rate in trauma patients receiving > 50 units of blood products warrants continued aggressive transfusion therapy in the first 24 hours after admission.

After the onset of sepsis, there is a marked dysfunction in cell-mediated immunity that contributes to the morbidity and mortality seen in this condition. Although both nitric oxide (NO) from inducible NO synthase (iNOS) and the activation of p38 mitogen-activated protein kinase (p38 MAPK) appear to contribute to this immune dysfunction, the extent to which NO regulates p38 MAPK activity in sepsis remains unknown. ⋯ These data suggest that NO release from iNOS regulates aspects of sepsis-induced immune dysfunction by the activation of p38 MAPK.

Our institution was one of the first to report the use of laparoscopy in the management of penetrating abdominal trauma (PAT) in 1977. Despite early interest, laparoscopy was rarely used. Changes in 1995 resulted in an increase in interest and use of laparoscopy. We present our recent experience with laparoscopy. ⋯ An aggressive laparoscopic program can improve patient management after PAT.
