Temporary intravascular shunts (TIVS) have been used as a damage control surgery (DCS) adjuncts in superior mesenteric artery (SMA) injuries, both experimentally and clinically. However, no study to date has evaluated the relationship between shunt indwelling time and resultant endothelial cell (EC) injury. We hypothesized that prolonged use of TIVS in SMA injuries would jeopardize EC integrity. ⋯ When possible, vascular reconstruction following use of shunts should include an interposition graft after debridement of the arterial edges having interfaced with the shunt. Finally, to minimize intimal injury to the native vessel, this model suggests that indwell times of shunts should be <9 hours.

Pediatric trauma results in lower mortality than adults and a high potential for lifelong functional impairment and reduced health-related quality of life (HRQL). There is no consensus regarding the best approach to measuring outcomes in this group. ⋯ Seriously injured children showed ongoing disability and reduced HRQL 12 months after injury. The CHQ-PF28 and PedsQL, and the mGOS and KOSCHI, performed comparably. The FIM demonstrated considerable ceiling effects, and improvement over time was not shown. The results inform the methodology of pediatric outcomes studies and protocol development for the routine follow-up of pediatric trauma patients.

Comparative Study
Comparison of trauma mortality and estimated cancer mortality from computed tomography during initial evaluation of intermediate-risk trauma patients.
Computed tomography (CT) is the primary source of nontherapeutic medical radiation exposure. Radiation exposure is associated with an increased risk of cancer mortality. Although the risk of cancer mortality is negligible in comparison with that of trauma mortality in high-risk patients, the balance of risk versus benefit in patients with less severe mechanisms of injury is unknown. ⋯ The risk of mortality from trauma is six times higher than the estimated risk of radiation-induced cancer mortality in intermediate level trauma patients. The mortality due to trauma is greatest in older patients, suggesting lower clinical suspicion is needed to warrant CT studies in this population. Efforts to reduce radiation exposure to trauma patients should focus on young patients with minor injuries.
