Large intracerebral hemorrhages (ICHs) are associated with significant morbidity and mortality. Patient transfer to higher level centers is common, but care in these centers rarely demonstrably improves morbidity or reduces mortality. Patients may rapidly progress to brain death, but a large number die shortly after transferring because of withdrawal of life-sustaining treatment (WOLST). This outcome may result in poor resource use and unnecessary cost to patients, families, and institutions. We sought to determine clinical and radiographic predictors of early death or WOLST that may alter potential transfer. ⋯ Early death or WOLST after ICH within 24 h of presentation was most associated with DNR/DNI code status, warfarin use, ICH score, and lower level of consciousness at presentation. These characteristics may be used by clinicians to guide conversations prior to transfer to tertiary care centers.

All available recommendations about the management of antithrombotic therapies (ATs) in patients who experienced traumatic brain injury (TBI) are mainly based on expert opinion because of the lack of strength in the available evidence-based medicine. Currently, the withdrawal and the resumption of AT in these patients is empirical, widely variable, and based on the individual assessment of the attending physician. The main difficulty is to balance the thrombotic and hemorrhagic risks to improve patient outcome. ⋯ The initial establishment of a thrombotic and/or bleeding risk scoring system can provide a vital theoretical basis for the evaluation of effective management in individuals under AT who sustained an iTBI. The listed recommendations can be implemented into local protocols for a more homogeneous strategy. Validation using large cohorts of patients needs to be developed. This is the first part of a project to update the management of AT in patients with iTBI.

Malignant brain edema (MBE) is a life-threatening complication that can occur after mechanical thrombectomy (MT) for acute ischemic stroke. The hypoperfusion intensity ratio (HIR) reflects the tissue-level perfusion status within the ischemic territory. This study investigated the association between HIR and MBE occurrence after MT in patients with anterior circulation large artery occlusion. ⋯ The presence of a higher HIR on pretreatment perfusion imaging serves as a robust predictor for MBE occurrence after MT, irrespective of successful recanalization.

The objective of this study was to identify barriers to surrogate decision-maker application of patient values on life-sustaining treatments after stroke in Mexican American (MA) and non-Hispanic White (NHW) patients. ⋯ Stroke surrogate decision-makers may benefit from (1) continued efforts to make advance care planning more common and more relevant, (2) assistance in how to apply their knowledge of patient values to actual treatment decisions, and (3) psychosocial support to reduce emotional burden. Barriers to surrogate application of patient values were generally similar in MA and NHW participants, though the possibility of greater guilt or burden among MA surrogates warrants further investigation and confirmation.

Somatosensory evoked potentials (SSEPs) help prognostication, particularly in patients with diffuse brain injury. However, use of SSEP is limited in critical care. We propose a novel, low-cost approach allowing acquisition of screening SSEP using widely available intensive care unit (ICU) equipment, specifically a peripheral "train-of-four" stimulator and standard electroencephalograph. ⋯ Somatosensory evoked potentials can reliably be recorded using the proposed approach. Given the very good but slightly lower sensitivity of absent SSEPs in the proposed screening approach, confirmation of absent SSEP responses using standard SSEP recordings is advised.
