      Abstract: imageThe 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. The goal of this consensus statement is to provide recommendations for anesthetic management considering the following (and they are): (1) optimal neurological outcomes for patients; (2) minimizing the risk for health care professionals, and (3) facilitating judicious use of resources while accounting for existing variability in care. 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.

  • Perioperative Care of Patients at High Risk for Stroke During or After
           Non-cardiac, Non-neurological Surgery: 2020 Guidelines From the Society
           for Neuroscience in Anesthesiology and Critical Care
    • Authors: Vlisides; Phillip E.; Moore, Laurel E.; Whalin, Matthew K.; Robicsek, Steven A.; Gelb, Adrian W.; Lele, Abhijit V.; Mashour, George A.
      Abstract: imagePerioperative stroke is associated with considerable morbidity and mortality. Stroke recognition and diagnosis are challenging perioperatively, and surgical patients receive therapeutic interventions less frequently compared with stroke patients in the outpatient setting. These updated guidelines from the Society for Neuroscience in Anesthesiology and Critical Care provide evidence-based recommendations regarding perioperative care of patients at high risk for stroke. Recommended areas for future investigation are also proposed.

  • Impact of Anesthesia on Long-term Outcomes in Patients With Supratentorial
           High-grade Glioma Undergoing Tumor Resection: A Retrospective Cohort Study
    • Authors: Dong; Jia; Zeng, Min; Ji, Nan; Hao, Shuyu; Zhou, Yang; Gao, Zhixian; Gu, Hongqiu; Zhang, Li; Ma, Daqing; Peng, Yuming; Han, Ruquan
      Abstract: imageBackground: 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.Methods: This study investigated 154 patients who received propofol and 140 patients who received sevoflurane for maintenance of anesthesia during HGG tumor resection. The primary outcomes were progression-free survival and overall survival.Results: Median progression-free survival was 10 months (interquartile range [IQR], 6 to 18) versus 11 months (IQR 6 to 20; P=0.674), and median overall survival was 18 months (IQR, 11 to 39) versus 18 months (IQR, 10 to 44; P=0.759) in patients maintained with propofol and sevoflurane, respectively. Higher preoperative Karnofsky performance status and postoperative chemotherapy were associated with a reduced hazard of tumor progression or death, whereas higher age-adjusted Charlson comorbidity index and longer duration of anesthesia were associated with an increased hazard of progression or death. World Health Organization tumor classification IV and incomplete tumor resection were associated with an increased hazard of tumor progression but not death. Anesthesia maintenance with sevoflurane increased the risk of death in patients with Karnofsky performance status

  • Near-infrared Spectroscopy–derived Cerebral Autoregulation Indices
           Independently Predict Clinical Outcome in Acutely Ill Comatose Patients
    • Authors: Rivera-Lara; Lucia; Geocadin, Romegryko; Zorrilla-Vaca, Andres; Healy, Ryan; Radzik, Batya R.; Palmisano, Caitlin; White, Mirinda A.; Sha, Dhaval; Ponce-Mejia, Luciano; Brown, Charles; Hogue, Charles; Ziai, Wendy C.
      Abstract: imageObjective: Outcome prediction in comatose patients with acute brain injury remains challenging. Regional cerebral oxygenation (rSO2) derived from near-infrared spectroscopy (NIRS) is a surrogate for cerebral blood flow and can be used to calculate cerebral autoregulation (CA) continuously at the bedside from the derived cerebral oximetry index (COx). We hypothesized that COx derived thresholds for CA are associated with outcomes in patients with acute coma from neurological injury.Methods: A prospective cohort study was conducted in 88 acutely comatose adults with heterogenous brain injury diagnoses who were continuously monitored with COx for up to 3 consecutive days. Multivariable logistic regression was performed to investigate association between averaged COx and short (in-hospital and 3 mo) and long-term (6 mo) outcomes.Results: Six month mortality rate was 62%. Median COx in nonsurvivors at hospital discharge was 0.082 [interquartile range, IQR: 0.045 to 0.160] compared with 0.042 [IQR: −0.005 to 0.110] in survivors (P=0.012). At 6 months, median COx was 0.075 [IQR: 0.27 to 0.158] in nonsurvivors compared with 0.029 [IQR: −0.015 to 0.077] in survivors (P=0.02). In the multivariable logistic regression model adjusted for confounders, average COx ≥0.05 was associated with both in-hospital mortality (adjusted odds ratio [OR]=2.9, 95% confidence interval [CI]=1.15-7.33, P=0.02), mortality at 6 months (adjusted OR=4.4, 95% CI=1.41-13.7, P=0.01), and severe disability (modified Rankin Score ≥4) at 6 months (adjusted OR=4.4, 95% CI=1.07-17.8, P=0.04). Area under the receiver operating characteristic curve for predicting mortality and severe disability at 6 months were 0.783 and 0.825, respectively.Conclusions: Averaged COx ≥0.05 is independently associated with short and long-term mortality and long-term severe disability in acutely comatose adults with neurological injury. We propose that COx ≥0.05 represents an accurate threshold to predict long-term functional outcome in acutely comatose adults.

  • Intubating 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
    • Authors: Swain; Amlan; Bhagat, Hemant; Gupta, Vivek; Salunke, Pravin; Panda, Nidhi B.; Sahu, Seelora
      Abstract: imageBackground: 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.Materials and Methods: In total, 40 consenting patients without history of abnormalities of cervical spine and planned for elective neuroradiologic interventions in the angiography suite were enrolled in this randomized crossover trial. Every patient was subjected to LMA Fastrach-guided flexible bronchoscopic as well as video laryngoscopy guided intubation. Cervical spine motion at the occipital bone, C1-C5 vertebrae, the occiput-C1, C1-C2, C2-C3 and C4-C5 junctions was investigated using continuous fluoroscopy during intubation. The primary outcome of the study was combined craniocervical motion from occiput to C5 between the 2 intubation techniques.Results: There was less (62%) combined craniocervical movement from occiput to C5 during the LMA Fastrach-flexible bronchoscopy-guided technique as compared with video laryngoscopy-guided intubation (17.55±14.23 vs. 28.95±11.58 degrees, respectively; P

  • Cervical Spine Movement During Awake Orotracheal Intubation With
           Fiberoptic Scope and McGrath Videolaryngoscope in Patients Undergoing
           Surgery for Cervical Spine Instability: A Randomized Control Trial
    • Authors: Dutta; Kaustuv; Sriganesh, Kamath; Chakrabarti, Dhritiman; Pruthi, Nupur; Reddy, Madhusudan
      Abstract: imageBackground: Cervical spine movement during intubation with direct laryngoscopy can predispose to new-onset neurological deficits in patients with cervical spine instability. While fiberoptic-guided intubation (FGI) is mostly preferred in such patients, this is not always possible. Videolaryngoscopy results in less cervical spine movement than direct laryngoscopy and may be an alternative to FGI in patients with cervical spine instability. The objective of this study was to compare cervical spine movement during awake FGI with those during awake McGrath videolaryngoscope-guided intubation (VGI) in patients undergoing surgery for cervical spine instability.Methods: Forty-six adult patients with upper cervical spine instability scheduled for stabilization surgery were randomized to awake FGI or awake VGI. Cervical spine movement during intubation was assessed by changes in lateral fluoroscopic-measured angles (α and β at C1/C2 and C3 levels, respectively) at 3 time points: T1, preintubation; T2, during intubation; T3, postintubation. Motor power was assessed before and after intubation.Results: Patient demographics and airway characteristics were similar between the 2 groups. Cervical spine motion (in degrees) during intubation was significantly greater with VGI than FGI at C1/C2 (T3-T1, −8.02±8.11 vs. −1.47±3.31; P

  • High-fidelity Training Model for Measurement of Dynamic Optic Nerve Sheath
           Diameter Using Transorbital Ultrasonography
    • Authors: Hajat; Zakir; Dinsmore, Michael; Venkatraghavan, Lashmi
      Abstract: imageBackground: Transorbital ultrasonographic measurement of optic nerve sheath diameter (ONSD) is an important technique for bedside assessment of raised intracranial pressure (ICP). However, developing competency for this clinical skill requires practice scans on both normal subjects and patients with raised ICP. The aim of this study is to develop a high-fidelity training model capable of measuring dynamic changes in ONSD and to test the reliability and reproducibility of the model at different simulated ICP values.Materials and Methods: We designed and developed a high-fidelity training model for dynamic ONSD measurement using a hemispherical table tennis ball, mounted on a 3.0-mm pediatric microcuffed endotracheal tube (ETT). Two independent investigators then performed a randomized blinded study to assess the reliability and reproducibility of the model. A total of 30 ONSD measurements (10 measurements each for 3 ETT cuff volumes of 0.1, 0.2, and 0.3 mL, simulating an ONSD of a normal, borderline, and raised ICP, respectively) were performed by each investigator. Intraclass correlation coefficients and Bland-Altman plots were calculated to analyze the level of agreement between the investigators.Results: Our model was able to provide dynamic changes in ONSD secondary to ETT cuff volume changes. Small increments of 0.1 mL cuff volume changes produced immediate changes in ONSD that are similar to those observed in patients. The median interobserver difference in ONSD was 0.3 mm (interquartile range, 0. to 0.4 mm). Intraclass correlation coefficient was 0.89, 0.89, and 0.90 for 0.1, 0.2, and 0.3 mL ETT cuff volumes, respectively.Conclusions: We have developed a clinically relevant model capable of simulating changes in ONSD in patients with normal and raised ICP. This model could be a valuable training tool to gain scanning experience in optic nerve ultrasonography, and improve operators’ technical abilities.

  • Pulse Pressure Variations and Plethysmographic Variability Index Measured
           at Ear Are Able to Predict Fluid Responsiveness in the Sitting Position
           for Neurosurgery
    • Authors: Bapteste; Lionel; Carrillon, Romain; Javelier, Stéphanie; Guyotat, Jacques; Desgranges, François-P.; Lehot, Jean-j.; Lukaszewicz, Anne-c.
      Abstract: imageBackground: Pulse pressure variation (PPV) and plethysmographic variability index (PVI), dynamic indicators of preload dependence based on heart-lung interactions, are used to predict fluid responsiveness in mechanically ventilated patients in the supine position. The sitting position for neurosurgery, by changing intrathoracic blood volume, could affect the capacity of PPV and PVI to predict fluid responsiveness. The aim of the study was to assess the ability of PPV and PVI to predict fluid responsiveness during general anesthesia in the sitting position.Methods: In total, 31 patients were included after settling in the sitting position but before surgery began. PPV, PVI with a finger sensor (PVI finger), and PVI with an ear sensor (PVI ear) were recorded before and after a fluid challenge of hydroxylethylstarch 250 mL over 10 minute. Esophageal Doppler was used to record stroke volume. Patients were defined as fluid responders if stroke volume increased by more than 10% after the fluid challenge.Results: In total, 13 (42%) patients were fluid responders. PPV and PVI ear were higher in responders than in nonresponders before the fluid challenge (12±5 vs. 7±3; P=0.0005 and 14±5 vs. 8±3; P=0.001, respectively). Areas under the receiver-operating curves to predict fluid responsiveness were 0.87 for PPV (P

  • Language Monitoring in Brain Surgery Under General Anesthesia
    • Authors: Martin; Jennifer; Tyrand, Rémi; Lopez, Ursula; Bernasconi Pertusio, Françoise; Lysakowski, Christopher; Laganaro, Marina; Schaller, Karl; Boëx, Colette
      Abstract: imageBackground: Awake surgeries for cerebral lesion resection have several limitations including patient fear, discomfort, or pain. This study aimed to determine whether components of language function could be measured under general anesthesia. In this study, the occurrence of mismatch negativity (MMN) was searched in evoked potentials for phonological sounds.Materials and Methods: Five normal hearing, French native speaker, awake volunteers participated in evaluating the phonological task (4 females and 1 male). Eleven normal-hearing, French native speaker patients (6 left and 5 right hemisphere lesions) participated at the time of their tumor neurosurgery (3 females and 8 males). Repetitions of the standard syllable /pa/ with the insertion of 1 deviant /po/ were presented through earphones. The difference between averaged epochs of standards and deviants syllables determined the MMN. During surgery, total intravenous anesthesia was performed with propofol and synthetic opioid sufentanil. The bispectral index was targeted (40 to 60).Results: The MMN was found in all awake volunteers and validated by an N250 component. In the patient group, the electroencephalogram analysis was not possible in 4 of 11 patients because of anesthesia being too deep, burst suppression, or a high level of noise (>40 μV). Significant N250 response was obtained in 5 of 7 (71.4%) patients under general anesthesia. The 2 other patients also showed MMN which did not reach significance.Conclusions: To our knowledge, this is the first demonstration that phonological processing can be measured during brain surgery under general anesthesia, suggesting that some language processing persists under the condition of unconsciousness. These results encourage further study of language processing under general anesthesia with the goal of making intraoperative neuromonitoring.

  • Hypotension and Hypocapnia During General Anesthesia in Piglets: Study of
           S100b as an Acute Biomarker for Cerebral Tissue Injury
    • Authors: Clausen; Nicola G.; Antonsen, Steen; Spielmann, Nelly; Hansen, Tom G.; Weiss, Markus; Ringer, Simone K.
      Abstract: imageBackground: 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.Methods: Fifty-seven sevoflurane-midazolam anesthetized piglets aged 4 to 6 weeks were randomly allocated to control (n=9), hypotension (n=18), hypocapnia (n=20), or combined hypotension and hypocapnia (n=10). Hypotension (target mean arterial blood pressure: 35 to 38 or 27 to 30 mm Hg) was induced by blood withdrawal and nitroprusside infusion, and hypocapnia by hyperventilation (target PaCO2: 28 to 30 and 23 to 25 mm Hg). Serum S100b and albumin were measured at baseline, before and 60 minutes after the interventions, and following 60-minute recovery.Results: Serum S100b concentrations decreased over time (P=0.001), but there was no difference in S100b between control piglets and those exposed to hypotension, hypocapnea, or a combination of the both (P=0.105). Albumin decreased in all 4 groups (P=0.001).Conclusion: 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.
