Multicenter Study Comparative Study Observational StudyThe Impact of Pre-Hospital Administration of Lactated Ringer's Solution versus Normal Saline in Patients with Traumatic Brain Injury.
Lactated Ringer's (LR) and normal saline (NS) are both used for resuscitation of injured patients. NS has been associated with increased resuscitation volume, blood loss, acidosis, and coagulopathy compared with LR. We sought to determine if pre-hospital LR is associated with improved outcome compared with NS in patients with and without traumatic brain injury (TBI). ⋯ Fluid type had no effect on admission biochemical or physiological parameters, 6-hour RBC, or crystalloid requirement in either group. LR was associated with increased mortality compared with NS in patients with TBI. These results underscore the need for a prospective randomized trial comparing pre-hospital LR with NS in patients with TBI.

The effect of continuous hypertonic saline infusion and hypernatremia on mortality in patients with severe traumatic brain injury: a retrospective cohort study.
Hypertonic saline (HTS) is used to control intracranial pressure (ICP) in patients with traumatic brain injury (TBI); however, in prior studies, the resultant hypernatremia has been associated with increased mortality. We aimed to study the effect of HTS on ICP and mortality in patients with severe TBI. ⋯ Hypertonic saline and hypernatremia are not associated with hospital mortality in patients with severe TBI.

Longitudinal Diffusion Tensor Imaging Detects Recovery of Fractional Anisotropy Within Traumatic Axonal Injury Lesions.
Traumatic axonal injury (TAI) may be reversible, yet there are currently no clinical imaging tools to detect axonal recovery in patients with traumatic brain injury (TBI). We used diffusion tensor imaging (DTI) to characterize serial changes in fractional anisotropy (FA) within TAI lesions of the corpus callosum (CC). We hypothesized that recovery of FA within a TAI lesion correlates with better functional outcome. ⋯ In this retrospective longitudinal study, we provide initial evidence that FA can recover within TAI lesions. However, FA recovery did not correlate with improved functional outcomes. Prospective histopathological and clinical studies are needed to further elucidate whether lesional FA recovery indicates axonal healing and has prognostic significance.

Multicenter StudyTracheostomy is associated with decreased hospital mortality after moderate or severe isolated traumatic brain injury.
Data regarding the impact and timing of tracheostomy in patients with isolated traumatic brain injury (TBI) are ambiguous. Our goal was to evaluate the impact of tracheostomy on hospital mortality in patients with moderate or severe isolated TBI. ⋯ Despite the greater severity of head injury, patients with isolated TBI who underwent tracheostomy had a lower risk-adjusted mortality than patients who remained intubated. Reasons for this difference in outcome may be multifactorial and require further investigation.

Randomized Controlled Trial Multicenter StudyFever control management is preferable to mild therapeutic hypothermia in traumatic brain injury patients with Abbreviated Injury Scale 3-4: a multicenter, randomised controlled trial.
In our prospective, multi-center, randomized controlled trial (RCT)-the Brain Hypothermia (B-HYPO) study-we could not show any difference on neurological outcomes in patients probably because of the heterogeneity in the severity of their traumatic condition. We therefore aimed to clarify and compare the effectiveness of the two therapeutic temperature management regimens in severe (Abbreviated Injury Scale [AIS] 3-4) or critical trauma patients (AIS 5). In the present post hoc B-HYPO study, we re-evaluated data based on the severity of trauma as AIS 3-4 or AIS 5 and compared Glasgow Outcome Scale score and mortality at 6 months by per-protocol analyses. ⋯ The fever control group demonstrated a significant reduction of TBI-related mortality compared with the MTH group (9.7% vs. 34.0%, p = 0.02) and an increase of favorable neurological outcomes (64.5% vs. 51.1%, p = 0.26) in patients with AIS 3-4, although the latter was not statistically significant. There was no difference in mortality or favorable outcome in patients with AIS 5. Fever control may be considered instead of MTH in patients with TBI (AIS 3-4).
