Practice GuidelineAnesthetic Management of Endovascular Treatment of Acute Ischemic Stroke During COVID-19 Pandemic: Consensus Statement from Society for Neuroscience in Anesthesiology & Critical Care (SNACC)_Endorsed by Society of Vascular & Interventional Neurology (SVIN), Society of NeuroInterventional Surgery (SNIS), Neurocritical Care Society (NCS), and European Society of Minimally Invasive Neurological Therapy (ESMINT).
The pandemic of coronavirus disease 2019 (COVID-19) has unique implications for the anesthetic management of endovascular therapy for acute ischemic stroke. The Society for Neuroscience in Anesthesiology and Critical Care appointed a task force to provide timely, consensus-based expert recommendations using available evidence for the safe and effective anesthetic management of endovascular therapy for acute ischemic stroke during the COVID-19 pandemic. ⋯ It provides a framework for selecting the optimal anesthetic technique (general anesthesia or monitored anesthesia care) for a given patient and offers suggestions for best practices for anesthesia care during the pandemic. Institutions and health care providers are encouraged to adapt these recommendations to best suit local needs, considering existing practice standards and resource availability to ensure safety of patients and providers.

Hypotension and Hypocapnia During General Anesthesia in Piglets: Study of S100b as an Acute Biomarker for Cerebral Tissue Injury.
Hypotension and/or hypocapnia might increase general anesthesia (GA)-related neuromorbidity in infants, but safe levels of perioperative blood pressure are poorly defined. Serum protein S100b has been used as screening, monitoring, and prediction tool in the management of patients with traumatic brain injury. Using an animal model, we investigated serum S100b as an acute biomarker of cerebral hypoperfusion and cerebral cell dysfunction during hypotension, hypocapnia, or combined hypotension/hypocapnia during GA. ⋯ S100b did not increase following 60 minutes of systemic hypotension and/or hypocapnia during GA in piglets. In this setting, the use of S100b as a biomarker of cerebral cell tissue dysfunction cannot be supported.

Practice GuidelineNeuroanesthesia Practice During the COVID-19 Pandemic: Recommendations from Society for Neuroscience in Anesthesiology & Critical Care (SNACC).
The pandemic of coronavirus disease 2019 (COVID-19) has several implications relevant to neuroanesthesiologists, including neurological manifestations of the disease, impact of anesthesia provision for specific neurosurgical procedures and electroconvulsive therapy, and health care provider wellness. The Society for Neuroscience in Anesthesiology and Critical Care appointed a task force to provide timely, consensus-based expert guidance for neuroanesthesiologists during the COVID-19 pandemic. ⋯ This consensus statement provides information on the neurological manifestations of COVID-19, advice for neuroanesthesia clinical practice during emergent neurosurgery, interventional radiology (excluding endovascular treatment of acute ischemic stroke), transnasal neurosurgery, awake craniotomy and electroconvulsive therapy, as well as information about health care provider wellness. Institutions and health care providers are encouraged to adapt these recommendations to best suit local needs, considering existing practice standards and resource availability to ensure safety of patients and providers.

Randomized Controlled Trial Comparative StudyIntubating Laryngeal Mask Airway-assisted Flexible Bronchoscopic Intubation is Associated With Reduced Cervical Spine Motion When Compared With C-MAC Video Laryngoscopy-guided Intubation: A Prospective Randomized Cross Over Trial.
In the evolving research into cervical spine mechanics during airway intervention, new devices are being constantly added to the armamentarium of anesthesiologists. In this study we compared cervical spine movement during orotracheal intubation using an intubating laryngeal mask airway (LMA Fastrach) assisted flexible bronchoscope or video laryngoscope. ⋯ There was significantly less movement in the craniocervical and upper cervical spine during LMA Fastrach assisted flexible bronchoscopic intubation compared to video laryngoscopic intubation.

Observational StudyImpact of Anesthesia on Long-term Outcomes in Patients With Supratentorial High-grade Glioma Undergoing Tumor Resection: A Retrospective Cohort Study.
Intravenous and inhalational anesthesia might have different associations with long-term outcome in cancer patients, with reports of adverse effects of inhalation anesthesia. However, the effects of anesthesia in patients with high-grade glioma (HGG) are not known. ⋯ Compared with maintenance of anesthesia with propofol, sevoflurane did not worsen progression-free or overall survival in patients with HGG undergoing tumor resection. However, propofol might be beneficial in patients with poor preoperative Karnofsky performance status.
