ReviewPrecision Medicine in Acute Brain Injury: A Narrative Review.
Over the past few years, the concept of personalized medicine has percolated into the management of different neurological conditions. Improving outcomes after acute brain injury (ABI) continues to be a major challenge. Unrecognized individual multiomic variations in addition to multiple interacting processes may explain why we fail to observe comprehensive improvements in ABI outcomes even when applied treatments appear to be beneficial logically. ⋯ The challenge is to incorporate all the information obtained from genomic studies, other omic data, and individual variability into a practical tool that can be used to assist clinical decision-making. The effective execution of such strategies, which is still far away, requires the development of protocols on the basis of these complex interactions and strict adherence to management protocols. In this review, we will discuss various omics and physiological targets to guide individualized patient management after ABI.

ReviewA Narrative Review of the Published Literature, Hospital Practices, and Policies Related to External Ventricular Drains in the United States: The External Ventricular Drain Publications, Practices, and Policies (EVDPoP) Study.
External ventricular drain (EVD) placement and management pose risks to neurocritically ill patients. Yet, little is known about EVD management or hospital EVD management practices and policies in US hospitals. A narrative review was conducted to describe EVD-related publications reported in PubMed and Embase between 1953 and 2019, and a survey was used to examine US hospital EVD practices and policies, including adherence to EVD guideline recommendations. ⋯ In summary, the published literature related to EVD insertion and maintenance, and reported EVD hospital practices and policies, primarily focus on reducing EVD-associated infections. Still, overall adherence of hospital EVD policies to guideline recommendations is modest. To promote a culture of EVD safety, clinicians should focus on reducing all EVD-associated adverse events.

Pituitary Dysfunction After Aneurysmal Subarachnoid Hemorrhage: A Prospective Cohort Study.
The prevalence of pituitary dysfunction after aneurysmal subarachnoid hemorrhage (aSAH) remains incompletely elucidated. Furthermore, it is not clear whether these abnormalities impact patient outcomes. The aim of this study was to evaluate the prevalence of pituitary dysfunction after aSAH and its effect on outcomes. ⋯ Pituitary dysfunction is common after aSAH, but does not affect 6 to 12-month clinical outcomes.

Effect of Respiratory Physiological Changes on Optic Nerve Sheath Diameter and Cerebral Oxygen Saturation in Patients With Acute Traumatic Brain Injury.
Severe traumatic brain injury (TBI) results in raised intracranial pressure (ICP). Ultrasonographic measurement of the optic nerve sheath diameter (ONSD) is a noninvasive method for the assessment of raised ICP. Manipulation of positive end-expiratory pressure (PEEP) and end-tidal carbon dioxide (ETCO2) are often used to optimize ICP and improve oxygenation in TBI patients. This study evaluated the effects of PEEP and ETCO2 on ONSD and regional cerebral oxygen saturation (rScO2) in patients with acute TBI. ⋯ Increasing PEEP resulted in significant increases in ONSD and rScO2, whereas reducing ETCO2 significantly decreased ONSD and rScO2.

Feasibility of Full Neuromuscular Blockade During Transcranial Motor Evoked Potential Monitoring of Neurosurgical Procedures.
Transcranial motor evoked potential (TcMEP) monitoring is conventionally performed during surgical procedures without or with minimal neuromuscular blockade (NMB) because of its potential interference with signal interpretation. However, full blockade offers increased anesthetic management options and facilitates surgery. Here, the feasibility of TcMEP interpretation was assessed during full NMB in adult neurosurgical patients. ⋯ TcMEP interpretation may be feasible under greater levels of NMB than previously considered, allowing for monitoring with greater degrees of muscle relaxation. Consideration for monitoring TcMEP during full NMB should be made on a case-by-case basis, and baseline responses without blockade may predict which patients will have adequate responses for interpretation.
