Brainwave Self-Regulation During Bispectral Index Neurofeedback in Trauma Center Nurses and Physicians After Receiving Mindfulness Instructions.

Fifty-seven level I trauma center nurses/physicians participated in a 4-day intervention to learn relaxed alertness using mindfulness-based instructions and EEG neurofeedback. Neurofeedback was provided by a Bispectral Index (BIS) system that continuously displays a BIS value (0-100) on the monitor screen. Reductions in the BIS value indicate that power in a high-frequency band (30-47 Hz) is decreased and power in an intermediate band (11-20 Hz) is increased.

Hypertonic saline administration and complex traumatic brain injury outcomes: a retrospective study.

Although hypertonic saline (HTS) decreases intracranial pressure (ICP) with traumatic brain injury (TBI), its effects on survival and post-discharge neurologic function are less certain. We assessed the impact of HTS administration on TBI outcomes and hypothesized that favorable outcomes would be associated with larger amounts of 3% saline. This is a retrospective study of consecutive-patients with the following criteria: blunt trauma, age 18-70 years, intracranial hemorrhage, Glasgow Coma Scale score (GCS) 3-12, and mechanical ventilation ≥ 5 days.

Cerebral hypoxia in severely brain-injured patients is associated with admission Glasgow Coma Scale score, computed tomographic severity, cerebral perfusion pressure, and survival.

Background: The purpose of this study was to determine the relationship of cerebral hypoxia with admission Glasgow Coma Scale (GCS) score, brain computed tomographic (CT) severity, cerebral perfusion pressure (CPP), and survival in patients with severe brain injury.

Methods: CPP and noninvasive transcranial oximetry (Stco2) were recorded hourly for 6 days in patients with a GCS score < or = 8 (3,722 observations). CT score was derived from midline shift (0/1) plus abnormal cisterns (0/1) plus subarachnoid hemorrhage (SAH) (0/1) (range, 0-3).
