We are pleased to share several updates from the Journal of Neurosurgical Anesthesiology with the SNACC membership!

  • Update on the Neuroanesthesiology Update: JNA will no longer be publishing Neuroanesthesiology Update. Thanks to Drs. Jeff Pasternak and Bill Lanier for 18 annual literature summaries. JNA will continue to provide its readership with easily accessible key literature syntheses but in different formats. You can read more about these changes in an editorial in the January 2022 issue of JNA .
  • SNACC 2021 Abstracts: The abstracts from the virtual 2021 Annual Meeting are now published and available on the JNA website . Congratulations to all the authors!

The January issue of the Journal will feature several Editor’s Picks that are free to access:

  • Rizk A, Lashmi V, Shankar J, Schaller B, Chowdhury T. Reappearance of Neurological Deficits in Pathologic Brain: Are Sedatives and Opioids Culprits? A Systematic Review. Journal of Neurosurgical Anesthesiology 2021; 34(1)

    This systematic review of 12 studies demonstrated a consistent re-occurrence of neurological deficits following the administration of benzodiazepines and opioids. These manifestations were typically transient and involved unmasking and/or extension of prior injuries.

  • Buhl LK, Mueller AL Boone DM, Nozari A. Risk Factors for Delayed Extubation Following High Posterior Cervical and Occipital Fusion. Journal of Neurosurgical Anesthesiology 2021; 34(1)

The authors present a retrospective cohort study that identified the following risk factors for delayed extubation after surgery: age, procedure length, the fusion of C2, and percentage colloid administered. This analysis did not detect a difference in the rate of postoperative pulmonary complications between delayed and immediate extubation.

  • Cardim D, Czosnyka M, Chandrapatham K, Badenes R, Bertuccio A, Corradi F, Donnelly J, Pelosi P, Hutchinson PJ, Robba C. Arterial and Venous Cerebral Blood Flow Velocities and Their Correlation in Healthy Volunteers and Traumatic Brain Injury. Journal of Neurosurgical Anesthesiology 2021; 34(1)

This study compared the relationship between arterial and venous cerebral blood flow velocities between healthy volunteers and those with traumatic brain injury (TBI). The authors found a significant correlation in healthy volunteers and but not those with TBI overall. In addition, there were age and sex differences noted in healthy volunteers.

  • Yu B, Peng Y, Qiao H, Liu B, Wang M, Yang Z, Han R. The Application of Regional Cerebral Oxygenation Monitoring in the Prediction of Cerebral Hypoperfusion During Carotid Endarterectomy. Journal of Neurosurgical Anesthesiology 2021; 34(1)

During carotid endarterectomy under general anesthesia, decreases in rSO2 correlated with decreases in evoked potential amplitude during internal carotid clamping. A reduction of 16% or greater had the optimal diagnostic performance for the detection of hypoperfusion. The false-positive rate was 8.9% and represented a potential limitation in the use of this monitor to predict postoperative deficits.

  • Rajan S, Devarajan J, Krishnaney A, George A, Rasouli JJ, Avitsian R. Opioid Alternatives in Spine Surgery: A Narrative Review. Journal of Neurosurgical Anesthesiology 2021; 34(1)

This narrative review provides a comprehensive overview of multimodality analgesic regimens incorporating opioid-sparing adjuvants to manage pain after spine surgery.
