Social and behavioral outcomes following traumatic brain injury: What predicts outcome at 12 months post-insult?
This study sought to investigate social and behavioral outcomes 12 months following childhood traumatic brain injury (TBI) and to identify predictors of these outcomes. The study also compared rates of impairment in social and behavioral outcomes at 12 months post-injury between children with TBI and a typically developing (TD) control group. The study comprised 114 children ages 5.5 to 16.0 years, 79 with mild, moderate, or severe TBI and 35 TD children, group-matched for age, sex and socio-economic status. ⋯ Analysis of covariance models identified a significant mean difference between the mild and moderate groups for social problems only, but the moderate and severe TBI groups showed a higher rate of impairment, particularly in externalizing problems. Pre-injury function, injury severity, parent mental health, and child self-esteem all contributed significantly to predicting social and behavioral outcomes. Both injury and non-injury factors should be considered when identifying children at risk for long-term difficulties in social and behavioral domains.

The Impact of Prehospital Intubation With and Without Sedation on Outcome in Trauma Patients With a GCS of 8 or Less.
Although unconsciousness (Glasgow Coma Scale [GCS] 3 to 8) necessitates intubation according national guidelines, there is a notable lack of evidence to support this approach. This study evaluates the impact on outcome of prehospital intubation with and without sedation in trauma patients with a GCS of ≤8. ⋯ Observed outcome of prehospital intubated patients with a GCS of ≤8 seems less poor than predicted compared with nonintubated patients. Sedation before intubation might potentially decrease mortality and improve early neurological outcome. Further studies are required to clarify this issue.

Intracranial pressure monitoring after primary decompressive craniectomy in traumatic brain injury: a clinical study.
Intracranial pressure (ICP) monitoring represents an important tool in the management of traumatic brain injury (TBI). Although current information exists regarding ICP monitoring in secondary decompressive craniectomy (DC), little is known after primary DC following emergency hematoma evacuation. ⋯ Intracranial hypertension and/or low CPP occurs frequently after primary DC; their occurence is associated with an unfavorable neurological outcome. ICP monitoring appears useful in guiding therapy after primary DC.

Comparative StudyPOLYNITROXYLATED PEGYLATED HEMOGLOBIN: A NOVEL, SMALL VOLUME THERAPEUTIC FOR TRAUMATIC BRAIN INJURY RESUSCITATION: COMPARISON TO WHOLE BLOOD AND DOSE RESPONSE EVALUATION.
Resuscitation with polynitroxylated pegylated hemoglobin (PNPH), a pegylated bovine hemoglobin decorated with nitroxides, eliminated the need for fluid administration, reduced intracranial pressure (ICP) and brain edema, and produced neuroprotection in vitro and in vivo versus Lactated Ringer's solution (LR) in experimental traumatic brain injury (TBI) plus hemorrhagic shock (HS). We hypothesized that resuscitation with PNPH would improve acute physiology versus whole blood after TBI+HS and would be safe and effective across a wide dosage range. Anesthetized mice underwent controlled cortical impact and severe HS to mean arterial pressure (MAP) of 25-27 mm Hg for 35 min, then were resuscitated with PNPH, autologous whole blood, or LR. ⋯ PNPH was well tolerated across the dosing range and dramatically reduced fluid requirements in all doses-even 2 or 5 mL/kg (p < 0.001). ICP was significantly lower in PNPH-treated mice for most doses tested versus in LR-treated mice, although %-brain water did not differ between groups. Resuscitation with PNPH, versus resuscitation with LR or blood, improved MAP, HR, and ICP, reduced acidosis and hyperkalemia, and was well tolerated and effective across a wide dosing range, supporting ongoing pre-clinical development of PNPH for TBI resuscitation.

Meta AnalysisUpdating Evidence for Using Hypothermia in Pediatric Severe Traumatic Brain Injury: Conventional and Bayesian Meta-Analytic Perspectives.
To evaluate clinical trials of hypothermia management on outcome in pediatric patients with severe traumatic brain injury using conventional and Bayesian meta-analyses. ⋯ Conventional meta-analysis shows the null hypothesis-no difference between hypothermia versus normothermia on mortality and poor outcome-cannot be rejected. However, Bayesian meta-analysis shows chance of relative risk reduction of death greater than 20% with hypothermia versus normothermia is 1-in-3, which may be further altered by one's optimistic or skeptical belief about a patient.
