ReviewRole of Dexmedetomidine in Aneurysmal Subarachnoid Hemorrhage: A Comprehensive Scoping Review.
Dexmedetomidine (DEX), an α2-adrenergic agonist, has been widely used for anesthesia, pain control, and intensive care unit sedation. Besides sleep-like sedation, DEX has many other beneficial effects, such as anti-inflammation, antioxidation, and anticell death. Subarachnoid hemorrhage (SAH), a severe and potentially fatal form of stroke, is a complex disease that is divided into 2 phases: early brain injury and delayed cerebral ischemia. ⋯ In this scoping review, we critically assess the existing data on the potential protective effect of DEX after SAH. So far, only 1 retrospective clinical trial assessing the effect of DEX on clinical outcomes after SAH has been performed. Hence, more trials are still needed as well as translational research bringing results from bench to bedside.

Randomized Controlled TrialEffect of Electroencephalography Spectral Edge Frequency (SEF) and Patient State Index (PSI)-Guided Propofol-Remifentanil Anesthesia on Delirium After Laparoscopic Surgery: The eMODIPOD Randomized Controlled Trial.
The effect of SedLine electroencephalography (EEG)-guided anesthetic care on postoperative delirium (POD) has not been studied. ⋯ Compared with usual care, SedLine spectral edge frequency-guided and patient state index-guided propofol-remifentanil anesthetic care neither alters anesthetic delivery nor decreases the unexpected low incidence of POD in relatively young Chinese patients undergoing laparoscopic surgery.

ReviewThe Effects of Anesthetics on Glioma Progression: A Narrative Review.
There are many established factors that influence glioma progression, including patient age, grade of tumor, genetic mutations, extent of surgical resection, and chemoradiotherapy. Although the exposure time to anesthetics during glioma resection surgery is relatively brief, the hemodynamic changes involved and medications used, as well as the stress response throughout the perioperative period, may also influence postoperative outcomes in glioma patients. There are numerous studies that have demonstrated that choice of anesthesia influences non-brain cancer outcomes; of particular interest are those describing that the use of total intravenous anesthesia may yield superior outcomes compared with volatile agents in in vitro and human studies. Much remains to be discovered on the topic of anesthesia's effect on glioma progression.

Hemoglobin Concentration May Influence the Incidence of Postoperative Transient Neurological Events in Patients With Moyamoya After Extracranial-intracranial Arterial Bypass: A Retrospective Single Center Experience.
Moyamoya is a rare condition characterized by cerebral angiographic findings of intracranial carotid artery stenosis with abnormal net-like vessels in the brain, and often presents as transient ischemic attacks or intracranial hemorrhage. Revascularization in the form of extracranial-intracranial (EC-IC) artery bypass has demonstrated efficacy in preventing ischemic attacks and intracranial hemorrhage, although it is associated with a relatively high rate of perioperative ischemic and hemorrhagic stroke. This retrospective analysis aims to evaluate the possible association between postoperative hemoglobin (Hgb) concentration and early postoperative transient neurological events (TNEs) experienced at our center. ⋯ This study reports a possible association between postoperative Hgb level and the occurrence of TNEs within the first 24 hours after surgery in patients undergoing EC-IC for moyamoya.

Observational StudyUtility and Predictive Value of CHIIDA Score in Pediatric Traumatic Brain Injury: A Prospective Observational Study.
The Children's Intracranial Injury Decision Aid (CHIIDA) is a tool designed to stratify children with mild traumatic brain injury (mTBI). The aim of this study was to assess the utility and predictive value of CHIIDA in the assessment of the need for intensive care unit (ICU) admission in pediatric patients with mTBI. ⋯ CHIIDA score does not serve as reliable triage tool for identifying children with TBI who do not require ICU admission.
