Meta Analysis
Intracranial Pressure Monitoring in Moderate Traumatic Brain Injury: A Systematic Review and Meta-Analysis.
The principal aim of this study was to determine the prevalence of intracranial pressure (ICP) monitoring and intracranial hypertension (IHT) in patients treated for moderate traumatic brain injury (TBI). A secondary objective was to assess factors associated with ICP monitoring. ⋯ The prevalence of ICP monitoring in moderate TBI is low, but the prevalence of IHT is high among patients undergoing ICP monitoring. Current literature is limited in size and quality and does not identify factors associated with ICP monitoring or IHT. Further research is needed to guide the optimal use of ICP monitoring in moderate TBI.

On the basis of increased mortality associated with hyperchloremia among critically ill patients, we investigated the effect of occurrence of early hyperchloremia on death or disability at 90 days in patients with intracerebral hemorrhage (ICH). ⋯ ClinicalTrials.gov: NCT01176565.

Randomized Controlled Trial
The Prognostic Roles of Perihematomal Edema and Ventricular Size in Patients with Intracerebral Hemorrhage.
Conflicting data exist regarding the association of perihematomal edema (PHE) with outcomes after intracerebral hemorrhage (ICH). We performed a post hoc analysis of the ICH Deferoxamine trial to examine whether an early change in ventricular size (VS), as a composite measure of PHE growth and mass effect, intraventricular hemorrhage, and hydrocephalus, is a more accurate predictor of outcome than PHE measures alone. ⋯ Within the context of a randomized controlled trial with standardized imaging and functional assessments, we did not find significant associations between measures of PHE and outcome but documented an independent association between early increase in VS and lower odds of good clinical outcome.

Early neurological deterioration (END) after endovascular thrombectomy (EVT) is strongly associated with poor prognosis in patients with large vessel occlusion. The relationship between body temperature and END after EVT is unknown, which we aimed to investigate in this study. ⋯ In summary, there is a J-shaped association between the maximum body temperature within 24 h after EVT and END. Moreover, the risk of END differed according to the timing of fever onset.

Adequate oxygenation in patients with aneurysmal subarachnoid hemorrhage (SAH) is imperative. However, hyperoxia increases formation of reactive oxygen species and may be associated with a dose-dependent toxicity. We postulated a threshold for arterial partial pressure of oxygen (paO2) above which toxicity effects precipitate and sought to study the effects on 30-day mortality, favorable outcome at discharge and at 3 months, and delayed cerebral ischemia. ⋯ Integrals above the defined paO2 thresholds were dose-dependently associated with an increase in mortality in ventilated patients with SAH. When we considered time-weighted mean paO2, unfavorable outcomes and 30-day mortality were more frequent both below and above a certain range. Unfavorable outcomes increased in paO2 ranges usually defined as normoxia. This emphasizes the necessity to further characterize oxygenation thresholds in ventilated patients with SAH in prospective clinical studies.
