Multicenter Study
The effect of age on functional outcome in mild traumatic brain injury: 6-month report of a prospective multicenter trial.
Elderly patients (aged 60 years and older) have been demonstrated to have an increased mortality after isolated traumatic brain injury (TBI); however, the prognosis of those patients surviving their hospitalization is unknown. We hypothesized that surviving elderly patients would also have decreased functional outcome, and this study examined the functional outcome of patients with isolated TBI at discharge and at 6 months posthospitalization. ⋯ Functional outcome after isolated mild TBI as measured by the Glasgow Outcome Scale and modified FIM is generally good to excellent for both elderly and younger patients. Older patients required more inpatient rehabilitation and lagged behind their younger counterparts but continued to recover and improve after discharge. Although there were statistically significant differences in the FIM score at both discharge and 6 months, the clinical importance of these small differences in the mean FIM score to the patient's quality of life is less clear. Measurable improvement in functional status during the first 6 months after injury is observed in both groups. Aggressive management and care of older patients with TBI is warranted, and efforts should be made to decrease inpatient mortality. Continued follow-up is ongoing to determine whether these outcomes persist at 12 months.

The purpose of this report is to identify the most important research questions pertaining to the acute care of the injured patient using a Web-based Delphi technique to achieve expert opinion consensus. ⋯ This report identifies the areas of trauma care in which research efforts might best be directed. Fully 40% of the key research questions could be considered to fall under the interest and auspices of the CDC-NCIPC. The remaining questions cover a broad range of topics and likely funding sources, emphasizing the need for a coordinated oversight of research funding in trauma care.

Comparative Study
Sixty-five clinical cases of free tissue transfer using long arteriovenous fistulas or vein grafts.
Traumatic limb injuries requiring free tissue transfer for coverage, often lack healthy recipient vessels adjacent to the defect. In these patients, vein grafts are required to bridge the gap of either the artery, vein or both. For the latter situation, a temporary arteriovenous fistula (AVF) can be created and allowed to mature and then divided and used as recipient artery and veins for the free flap. ⋯ Although a longer graft length seemed to be associated with a higher re-exploration rate, there was no statistical significance. One-stage AVFs can be used with good results, however, two-stage AVFs are associated with a high graft occlusion rate, wound failure rate and limb amputation rate. In all cases, a large caliber graft such as the great saphenous vein provided a large (relatively low resistance) conduit for bridging the defect.

Clinical Trial Controlled Clinical Trial
Protocol-driven ventilator weaning reduces use of mechanical ventilation, rate of early reintubation, and ventilator-associated pneumonia.
Mechanical ventilation is the defining event of intensive care unit management. To reduce use, a literature-based protocol was introduced to facilitate weaning. The effect of protocol-driven ventilator weaning on ventilator use, ventilator-associated pneumonia (VAP), and intensive care unit (ICU) length of stay (LOS) is described in a survey of 2 years' activity in a multidisciplinary surgical ICU. ⋯ Protocol-driven weaning reduces use of mechanical ventilation and VAP. Injured and general surgical patients show reduction in complications, but shorter ICU LOS depends on resources elsewhere in the health care system.

Comparative Study
Therapeutic potential of exogenous ubiquitin during resuscitation from severe trauma.
Recent studies suggest that extracellular ubiquitin could have a physiologic role in immunodepression in sepsis and trauma. The therapeutic potential of exogenous ubiquitin after trauma has not been examined. To fill this gap, we designed a series of experiments in a clinically relevant trauma model. ⋯ Ubiquitin is apparently safe and effective for reducing fluid requirements as a measure of diffuse capillary leak. This immunomodulatory property suggests a new therapeutic approach after injury in particular, and for infectious and noninfectious inflammation in general.
