Recombinant factor VIIa (rFVIIa) has been used to decrease bleeding in a number of settings including hemophilia, liver transplantation, intractable bleeding, and cirrhosis. Experience in the trauma setting is limited. This study was performed to determine whether rFVIIa would reduce bleeding after a grade V liver injury in hypothermic, dilutionally coagulopathic pigs when used as an adjunct to abdominal packing and to determine whether increasing the dose of the drug increased its hemostatic efficacy. ⋯ rFVIIa reduces blood loss in hypothermic, dilutionally coagulopathic pigs with grade V injuries when used as an adjunct to packing. Increasing the dose does not enhance the hemostatic effect.

Helicopter transport of pediatric trauma patients in an urban Emergency Medical Services system remains controversial. ⋯ The majority of pediatric trauma patients transported by helicopter in our study sustained minor injuries. A revised policy to better identify pediatric patients who might benefit from helicopter transport appears to be warranted.

During the past decade, nonoperative management (NOM) of hemodynamically stable blunt trauma patients with liver (L) or spleen (S) injury has become the standard of care. This trend has led to concerns over missed associated intra-abdominal injuries with concomitant morbidity. To better understand the incidence and risk of missed injury, patterns of associated intra-abdominal injury were examined in all patients with blunt liver and spleen injuries, and missed injuries were reviewed in patients undergoing NOM. ⋯ Damage to the pancreas and bowel is significantly associated with liver as opposed to spleen injuries. Actual missed intra-abdominal injury with NOM mirrors this pattern, occurring more often with liver than with spleen injuries. However, the overall incidence of missed injury is quite low, and should not influence decisions concerning eligibility for NOM. We speculate that the greater amount and/or different vector of energy transfer needed to injure the liver versus the spleen accounts for the greater rate of associated injuries to the pancreas/small bowel.

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.
