Multicenter Study Comparative StudyClinical evaluation of a portable near-infrared device for detection of traumatic intracranial hematomas.
The purpose of this multicenter observational clinical study was to evaluate the performance of a near-infrared (NIR)-based, non-invasive, portable device to screen for traumatic intracranial hematomas. Five trauma centers collected data using the portable NIR device at the time a computed tomography (CT) scan was performed to evaluate a suspected traumatic brain injury (TBI). The CT scans were read by an independent neuroradiologist who was blinded to the NIR measurements. ⋯ For all 96 cases with intracranial hemorrhage, regardless of size and type of hemorrhage, the sensitivity was 68.7% (CI 58.3,77.6%), and specificity was 90.7% (CI 86.4,93.7%). These results confirm the results of previous studies that indicate that a NIR-based portable device can reliably screen for intracranial hematomas that are superficial and of a size likely to be of clinical importance. The NIR device cannot replace CT scanning in the diagnosis of TBI, but the device might be useful to supplement clinical information used to triage TBI patients, and in situations in which CT scanning is not readily available.

Multicenter Study Comparative StudyOutcomes of patients with severe traumatic brain injury who have Glasgow Coma Scale scores of 3 or 4 and are over 65 years old.
The goal of this study was to investigate the outcomes of patients with traumatic brain injury (TBI) who had Glasgow Coma Scale (GCS) scores of 3 or 4, and were aged 66 years or older. Between January 2001 and December 2005, 13 European centers enrolled patients with severe brain trauma. Data sets of all patients who had a GCS score of 3 or 4 and were 66 years of age or older were analyzed. ⋯ Patients with GCS scores of 3 or 4 who are older than 65 years have a poor, but not hopeless, prognosis. Confirmed factors predicting poor prognosis for this group of patients were closed basal cisterns and midline shift >15 mm on the first CT scan. Factors possibly related to favorable outcomes were female gender, lower trauma severity, open or partially open basal cisterns, and no midline shift on the first CT scan.
