Using the Spectrogram to Interpret Electroencephalographic (EEG) Waveforms

Authors: Seyed A. Safavynia, MD, PhD; Shobana Rajan, MD, FASA ASA Monitor May 2024, Vol. 88, 28–29. Electroencephalographic (EEG) monitoring has become increasingly commonplace in the anesthesiologist’s practice since the Bispectral IndexTM (BISTM) Monitor (Medtronic) was approved by the U.S. Food and Drug Administration (FDA) in 1996 for monitoring anesthetic depth. Today, several other intraoperative EEG devices exist, […]

Rethinking Coagulation Activation during Extracorporeal Membrane Oxygenation: Insights from the Case of Mr. Hageman

Authors: Kenichi A. Tanaka, M.D., M.Sc. et al  Anesthesiology July 2024, Vol. 141, 7–9. “… their findings … may have clinical implications for understanding ECMO-related bleeding. While they did not conclusively demonstrate a causal relationship, their data suggest that patients who bled had significantly elevated signals of contact activation based on biomarkers.” Blood surface interfacing that […]

Cortical Dynamics and Postoperative Cognition: Comment

Authors: Akira Kubo, M.S.; Koji Hosokawa, M.D., Ph.D. Anesthesiology July 2024, Vol. 141, 193–194. To the Editor: We read with great interest the recent article by Vlisides et al.  The authors demonstrated that while intraoperative cortical connectivity measured using 16-channel electroencephalography (EEG) was not linked to postoperative cognitive function, global theta activity was associated with postoperative delirium. The […]

Classification of Epiglottal Displacement

Authors: Akihiro Suzuki, M.D., Ph.D. et al  Anesthesiology July 2024, Vol. 141, 161–162. Displacement of the epiglottis, also known as epiglottic folding, downfolding, or prolapse, is an unexpected complication associated with tracheal intubation and supraglottic airway device insertion. Recent advancements in endoscopic technology and the widespread use of video/optical devices, such as videolaryngoscopes, have brought this […]

Science, Medicine, and the Anesthesiologist

Endovascular thrombectomy plus medical care versus medical care alone for large ischaemic stroke: 1-year outcomes of the SELECT2 trial. Lancet 2024; 403:731–40. PMID: 38346442. Author: Jamie Sleigh, M.D. Anesthesiology July 2024, Vol. 141, A13–A15. Although many trials have shown improved early recovery in patients with large ischemic stroke treated with endovascular thrombectomy, it is unknown whether […]

Activity of the Sodium Leak Channel Maintains the Excitability of Paraventricular Thalamus Glutamatergic Neurons to Resist Anesthetic Effects of Sevoflurane in Mice

Authors: Yujie Wu, M.M. et al  Anesthesiology July 2024, Vol. 141, 56–74. Background Stimulation of the paraventricular thalamus has been found to enhance anesthesia recovery; however, the underlying molecular mechanism by which general anesthetics modulate paraventricular thalamus is unclear. This study aimed to test the hypothesis that the sodium leak channel (NALCN) maintains neuronal activity in […]

Laryngeal Keel and Its Implications during Airway Management

Authors: Kirti Sahu, M.D. et al  Anesthesiology July 2024, Vol. 141, 159–160. A 15-YR-OLD boy with dysphonia and difficulty clearing secretions due to a glottic web underwent an endoscopic excision and Gore-Tex (W. L. Gore & Associates, Inc., USA) laryngeal keel placement (fig. 1). Laryngeal keels are used to achieve and maintain separation at the anterior […]
