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.

Comparative Study
A comparison of prehospital and hospital data in trauma patients.
The use of prehospital data as an indicator for trauma team activation has been established. The relationship between field (Fd) and emergency department (ED) systolic blood pressure (SBP), Glasgow Coma Scale (GCS) score, and airway control as it relates to outcomes is unclear. We hypothesized that ED and Fd physiologic parameters are equally valid predictors of outcomes. In addition, we hypothesized that early field intubation will improve survival compared with later ED intubation. ⋯ Early field intubation was associated with a decreased risk of fatal outcome compared with ED intubation. ED-GCS score was not significantly different from Fd-GCS score, and either one can be used to predict fatal outcome. However, ED-SBP was different from Fd-SBP in 40% of the patients, with the majority of cases having higher ED-SBP. Although ED-SBP was a better predictor of outcome, the best model is achieved when both ED and field SBP are used.

Despite current recommendations by the Brain Trauma Foundation regarding the placement of intracranial pressure (ICP) monitoring devices, advances in computed tomographic (CT) scan technology have led to the suggestion that increased ICP may be predicted by findings on admission head CT scan and that patients without such findings do not require such monitoring. A linear relationship exists between characteristics of admission head CT scan and initial ICP level, allowing for selective placement of ICP monitoring devices. ⋯ Therefore, the current Brain Trauma Foundation recommendation of ICP monitoring in those patients presenting with a GCS score < 8 with an abnormal CT scan or a normal CT scan with age > 40 years, systolic blood pressure < 90 mm Hg, or exhibiting posturing should be followed.

Endotracheal intubation remains the gold standard for trauma airway management. Rapid sequence intubation (RSI) has traditionally been performed by anesthesiologists but increasingly, emergency physicians are also undertaking RSI. We aimed to compare success and complication rates for trauma intubations for the two specialties. ⋯ There is no significant difference in complication rates for trauma RSI between emergency physicians and anesthesiologists in Scottish urban centers. A collaborative approach to the critical trauma airway is vital. Emergency physicians should consult with senior anesthesiologists before RSI when intubation is predicted to be difficult.

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.
