ReviewThe Role of Multimodal Invasive Monitoring in Acute Traumatic Brain Injury.
This article reviews the role of modalities that directly monitor brain parenchyma in patients with severe traumatic brain injury. The physiology monitored involves compartmental and perfusion pressures, tissue oxygenation and metabolism, quantitative blood flow, pressure autoregulation, and electrophysiology. There are several proposed roles for this multimodality monitoring, such as to track, prevent, and treat the cascade of secondary brain injury; monitor the neurologically injured patient; integrate various data into a composite, patient-specific, and dynamic picture; apply protocolized, pathophysiology-driven intensive care; use as a prognostic marker; and understand pathophysiologic mechanisms involved in secondary brain injury to develop preventive and abortive therapies, and to inform future clinical trials.

Moderate traumatic brain injury (MTBI) is poorly defined in the literature and the nomenclature "moderate" is misleading, because up to 15 % of such patients may die. MTBI is a heterogeneous entity that shares many aspects of its pathophysiology and management with severe traumatic brain injury. Many patients who ''talk and died'' are MTBI. ⋯ On the other hand, those with higher range GCS (11-13) can be managed more conservatively with serial neurological examination and CT scans. Given the available evidence, MTBI is an entity that needs reclassification. Large-scale and well-designed studies are urgently needed.

Randomized Controlled Trial Multicenter Study
Plasma Potassium Concentration on Admission Correlates with Neurological Outcome in Traumatic Brain Injury Patients Treated with Targeted Temperature Management: a Post Hoc Analyses of a Multicenter Randomized Controlled Trial.
Recent studies have focused on the association between plasma electrolytes, particularly potassium level and neurologic outcomes in patients with traumatic brain injury (TBI). We hypothesized that potassium level on admission is an indicator for initiation of targeted temperature management in patients with severe TBI. ⋯ The initial potassium level may be an indicator in determining appropriate targeted temperature management for patients with TBI. Fever control may be considered instead of MTH for normokalemia patients with TBI on admission.

Integration of palliative care (PC) into the neurological intensive care unit (neuro-ICU) is increasingly recommended, but evidence regarding the best practice is lacking. We conducted a qualitative analysis exploring current practices and key themes of specialist PC consultations in patients admitted to a single neuro-ICU. ⋯ PC consultations in the neuro-ICU emphasize family coping and decision-making by helping discuss prognosis and exploring patient and family values as well as their ability to understand the medical information. Several features suggest that earlier integration of PC into neuro-ICU care may enhance both coping and the decision-making process.

Head injury following explosions is common. Rapid identification of patients with severe traumatic brain injury (TBI) in need of neurosurgical intervention is complicated in a situation where multiple casualties are admitted following an explosion. ⋯ Following an explosion in the civilian setting, 65 patients (38%) with GCS scores of 3 to 14 did not experience severe TBI. The proportion of patients with severe TBI and severe TBI in need of a neurosurgical intervention were similar in patients presenting with GCS scores of 3 to 8 and GCS scores of 9 to 14. In this study, GCS and Simplified Motor Score did not help identify patients with severe TBI in need of a neurosurgical intervention.
