The principle of optimizing oxygen delivery to the injured brain rests on the premise that both hypoxia and hyperoxia are important mediators of secondary brain injury and should be avoided. This rationale has prompted a move towards incorporating oxygenation endpoints into the management of neurocritical care patients, particularly those with traumatic brain injury. The present review will seek to describe clinical strategies to optimize oxygenation in the acutely brain-injured patient, drawing upon relevant physiologic principles and clinical data, where it exists. ⋯ Although there is growing interest in the use of brain tissue oxygenation as a resuscitative endpoint, many of these therapies are based on physiologic principles with little robust clinical evidence to guide their application. Clinicians must be mindful of this and balance the putative benefits of improving oxygenation against the risks associated with the use of such therapies.

There is a lack of consistent, evidence-based guidelines for the management of patients with fever after brain injury. The aim was to update previously published consensus recommendations on targeted temperature management after intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke in patients who require admission to critical care. ⋯ Based on a modified Delphi expert consensus process, these guidelines aim to improve the quality of targeted temperature management for patients after intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke in critical care, highlighting the need for further research to improve clinical guidelines in this setting.

Neurocritical care is a relatively young subspecialty that is rapidly coming into its own. As the neurocritical care community has expanded, the process of training and credentialing physicians in this growing field has undergone a rapid evolution. This article will review the history and current state of neurocritical care training and education, physician certification, and program accreditation in the United States within the larger context of critical care training across subspecialties.

Observational Study
Myocardial dysfunction assessed by speckle-tracking in good-grade subarachnoid hemorrhage patients (WFNS 1-2): a prospective observational study.
Cardiac complications due to non-traumatic subarachnoid hemorrhage (SAH) are usually described using classical echocardiographic evaluation. Strain imaging appears to have better sensitivity than standard echocardiographic markers for the diagnosis of left ventricular dysfunction. The aim of this study was to determine the prevalence of cardiac dysfunction defined as a Global Longitudinal Strain (GLS) ≥ - 20% in patients with good-grade SAH (WFNS 1 or 2). ⋯ Strain imaging showed a higher prevalence (60.6%) of left ventricular dysfunction during the acute phase of good-grade SAH (WFNS 1 or 2) than previously described.

This proceedings article presents the scope of pediatric coma and disorders of consciousness based on presentations and discussions at the First Pediatric Disorders of Consciousness Care and Research symposium held on September 14th, 2021. Herein we review the current state of pediatric coma care and research opportunities as well as shared experiences from seasoned researchers and clinicians. Salient current challenges and opportunities in pediatric and neonatal coma care and research were identified through the contributions of the presenters, who were Jose I. ⋯ Boerwinkle, MD, with overview by Mark Wainwright, MD, and subsequent audience discussion. The program, executively planned by Varina L. Boerwinkle, MD, Mark Wainwright, MD, and Michelle Elena Schober, MD, drove the identification and development of priorities for the pediatric neurocritical care community.
