The use of antithrombotic agents, including anticoagulants, antiplatelet agents, and thrombolytics has increased over the last decade and is expected to continue to rise. Although antithrombotic-associated intracranial hemorrhage can be devastating, rapid reversal of coagulopathy may help limit hematoma expansion and improve outcomes. ⋯ This guideline provides timely, evidence-based reversal strategies to assist practitioners in the care of patients with antithrombotic-associated intracranial hemorrhage.

Multicenter Study Observational Study
Multi-Center Study of Diffusion-Weighted Imaging in Coma After Cardiac Arrest.
The ability to predict outcomes in acutely comatose cardiac arrest survivors is limited. Brain diffusion-weighted magnetic resonance imaging (DWI MRI) has been shown in initial studies to be a simple and effective prognostic tool. This study aimed to determine the predictive value of previously defined DWI MRI thresholds in a multi-center cohort. ⋯ In patients who remain comatose after cardiac arrest, quantitative DWI MRI findings correlate with early recovery of consciousness. A DWI MRI threshold of 650 × 10(-6) mm(2)/s in ≥10% of brain volume can differentiate patients with good versus poor outcome, though in this patient population the threshold was not 100% specific for poor outcome.

Randomized Controlled Trial Multicenter Study
Glyburide Advantage in Malignant Edema and Stroke (GAMES-RP) Trial: Rationale and Design.
Patients with large territory infarction are at high risk of cerebral edema and neurological deterioration, including death. Preclinical studies have shown that a continuous infusion of glyburide blocks edema formation and improves outcome. We hypothesize that treatment with RP-1127 (Glyburide for Injection) reduces formation of brain edema in patients after large anterior circulation infarction. ⋯ GAMES-RP was designed to provide critical information regarding glyburide for injection in patients with large hemispheric stroke and will inform the design of future studies.

The risk of death from venous thromboembolism (VTE) is high in intensive care unit patients with neurological diagnoses. This is due to an increased risk of venous stasis secondary to paralysis as well as an increased prevalence of underlying pathologies that cause endothelial activation and create an increased risk of embolus formation. ⋯ The lack of a solid evidentiary base has posed challenges for the establishment of consistent and evidence-based clinical practice standards. In response to this need for guidance, the Neurocritical Care Society set out to develop and evidence-based guideline using GRADE to safely reduce VTE and its associated complications.

Review Case Reports
Bowel Ischemia in Refractory Status Epilepticus: Report of Two Cases and Review of the Literature.
Bowel ischemia is a rare life threatening complication seen in patients with refractory status epilepticus (RSE). The few reported cases of bowel ischemia in this setting have been associated with the use continuous barbiturate infusions. We report two patients with RSE in the absence of barbiturate infusion and without clear structural, infectious, anatomic, vascular, or autoimmune etiology. We review the clinical details of the cases and potential factors involved in the development of non-occlusive bowel ischemia in patients with RSE. ⋯ The mechanism of bowel infarction in these cases is likely multifactorial and was not associated with barbiturate use. Likely contributors to ischemia include RSE itself, systemic hypotension, vasopressor use, general anesthesia, and abnormal cardiac function. During the management of RSE, every effort must be made to avoid the secondary complications such as bowel ischemia.
