In this episode of The Nurse Anesthesia Podcast, host Jeremy Heiner, is joined by co-host Mark Gabot, and special guest Zohn Centimole, PhD, CRNA, for a practical discussion about moving “beyond the BIS Index number” and using electroencephalography (EEG) to better understand the brain’s response to anesthesia. The conversation explores how raw and processed EEG can provide anesthesia professionals with a real-time window into the organ they are actually anesthetizing—the brain.Jeremy, Mark, and Zohn then break down the characteristic EEG frequencies encountered during anesthesia. They talk about burst suppression, the density spectral array (DSA), and how recognizing patterns may allow clinicians to titrate anesthetics more thoughtfully and individualize care rather than relying exclusively on MAC values, vital signs, or traditional dosing strategies.The takeaway is simple: let’s start looking at the EEG! Put the monitor on, observe the changes from induction through emergence, correlate the patterns with anesthetic interventions, and begin developing the skills necessary to use brain monitoring as another tool for individualizing anesthesia care.References1.    Aldecoa C, Bettelli G, Bilotta F, et al.
