Data on health-related costs after aneurysmal subarachnoid hemorrhage (aSAH) are limited. The aim was to evaluate outcome, return to work and costs after aSAH with focus on differences between high- and low-grade aSAH (defined as World Federation of Neurological Surgeons [WFNS] grades 4-5 and WFNS 1-3, respectively). ⋯ Favorable outcome can be achieved in a considerable proportion of high-grade aSAH patients, but costs are greater compared to low-grade aSAH. Further cost-effectiveness studies in the current era of aSAH management are needed.

Comparative Study Observational Study
Comparison of Three Point-of-Care Ultrasound Views and MRI Measurements for Optic Nerve Sheath Diameter: A Prospective Validity Study.
Point-of-care ultrasound of the optic nerve sheath diameter (ONSD) to diagnose increased intracranial pressure (ICP) is of great interest in various clinical scenarios. Yet, the lack of examination standardization has made clinical utility difficult. We compare three ultrasound ocular plane views (inferior, sagittal, and transverse), which are currently used in the literature to evaluate their consistency. Comparisons for each view to magnetic resonance imaging (MRI) measurements were also made. ⋯ Our findings suggest that absolute measurements should not be compared across different ultrasound orientations given the wide variability in the correlation between the ultrasound views used to assess the optic nerve sheath. The inferior and transverse ultrasound views are the most likely to yield high-quality images, although the specific view, for the best image, in an individual patient can vary. We would caution against absolute values of ONSD to indicate increased ICP, as it may be view dependent.

Observational Study
Sleep Measure Validation in a Pediatric Neurocritical Care Acquired Brain Injury Population.
Lingering morbidities including physical, cognitive, emotional, and psychosocial sequelae, termed the Post-Intensive Care Syndrome, persist years after pediatric neurocritical care (PNCC) hospitalization. Sleep disturbances impact other Post-Intensive Care Syndrome domains and are under-evaluated to date due to a lack of appropriate measurement tools. The present study evaluated the validity of the Sleep Disturbance Scale for Children (SDSC) to address the growing need for assessing sleep problems after PNCC. ⋯ The SDSC is a valid and reliable measure for assessing sleep disturbances in children after PNCC. Results support the use of the SDSC to measure sleep disturbances after PNCC. Targeted interventions for sleep disturbances may be key to overall patient recovery.

For years, the use of ketamine as an anesthetic to patients suffering from acute brain injury has been debated because of its possible deleterious effects on the cerebral circulation and thus on the cerebral perfusion. Early studies suggested that ketamine could increase the intracranial pressure thus lowering the cerebral perfusion and hence reduce the oxygen supply to the injured brain. However, more recent studies are less conclusive and might even indicate that patients with acute brain injury could benefit from ketamine sedation. ⋯ The overall level of evidence concerning the use of ketamine in brain injury is low. Only two studies found a small increase in intracranial pressure, while two small studies found decreased levels of intracranial pressure following ketamine administration. We found no evidence of harm during ketamine use in patients suffering from acute brain injury.
