Episode SummaryIn this episode of the nurse anesthesia podcast, Jeremy dives into some Airway Management Adventures! He discusses three airway cases from the Emergency Department to the Operating Room. Each case illustrates critical decision-making under challenging circumstances where key actions by the CRNA are essential. The cases include information on preoxygenation with nasal cannula and a non-rebreather mask, RSI, successful first-pass intubation using video-laryngoscopy, cricothyrotomy, and awake intubation. Major themes discussed in this episode involve preparation with airway plans, checklist use, stress preparation, adaptability, team coordination, and continuous learning from both success and difficulty in airway management. Resources/information discussed in podcast·         Get your free The Nurse Anesthesia Crisis Checklists at www.thenurseanesthesia.com·         Sign up for our Crisis Management Video Series.

In Episode 26 we welcome a special guest…Rhea Temmermand from the Atomic Anesthesia Podcast! Jeremy talks with Rhea about cognitive aids—like crisis checklists—which are essential tools in anesthesia for guiding rapid decision-making during high-stakes medical emergencies. Originally inspired by aviation’s Crew Resource Management, these aids were adapted for anesthesia…giving rise to Anesthesia Crisis Resource Management (ACRM). Using crisis checklists can help enhance performance, boosts patient safety, and supports better outcomes in perioperative care.

Asthma is a chronic inflammatory disorder of the airways characterized by hyperresponsiveness, variable airflow obstruction, and airway remodeling. In the OR, we’re less concerned about chronic control and more focused on acute airway events…namely, bronchospasm.Bronchospasm during general anesthesia can be insidious. You may see rising peak airway pressures, decreased tidal volumes, wheezing if you’re lucky…and if you’re unlucky…desaturation and hypotension. Time is tissue. That’s when it’s time to get medications like albuterol and epinephrine out of the anesthesia cart.In today’s episode, Sass and Jeremy discuss the pharmacology of albuterol and epinephrine as they relate to the management of intraoperative bronchospasm. ReferencesMaddah SA, et al.

Episode 23 begins with Jeremy and Sass discussing the historical background of cannabis or “marijuana” use, and then dive into how this psychoactive drug affects each body system. They focus on what you need to know when providing anesthesia for an individual who is a chronic user or acutely intoxicated.

Episode SummaryMonitoring the depth of anesthesia, as a CRNA, is important for any surgical or medical procedure. In this episode of The Nurse Anesthesia Podcast, Jeremy and Sass review the bispectral index (BIS) monitor. They discuss the various electroencephalographic (EEG) waveforms the BIS monitor uses to determine depth of anesthesia, and identify the factors and medications that influence the BIS monitor. They finish the episode with an interesting set of studies that investigated at how electromyographic (EMG) activity is incorporated into the BIS algorithm. This is definitely one episode you’ll want to download and catch up on! References1.    Gu, Yichun et al. “Effectiveness Assessment of Bispectral Index Monitoring Compared with Conventional Monitoring in General Anesthesia: A Systematic Review and Meta-Analysis.” Anesthesiology research and practice vol. 2024 5555481. 7 Aug. 2024. 2.    Messner, M et al. “The bispectral index declines during neuromuscular block in fully awake persons.” Anesthesia and analgesia vol. 97,2 (2003): 488-491. 3.    Schuller, P J et al. “Response of bispectral index to neuromuscular block in awake volunteers.” British journal of anaesthesia vol. 115 Suppl 1 (2015): i95-i103.  About The Nurse AnesthesiaWe are building a commUNITY of learning in anesthesia and critical care!

In this episode of The Nurse Anesthesia Podcast, Jeremy & Sass discuss what happens when the routine treatments for intraoperative hypotension don’t work, and focus on the interventions you can consider when refractory hypotension occurs. They talk about different causes of refractory hypotension with a focus on vasoplegic syndrome. They discuss the differences between refractory hypotension and vasoplegic syndrome, and then identify the potential causes and specific treatments for this rare condition. ReferencesArevalo VN.

Anesthesia induced hypotension is commonly treated with push dose vasopressors. Today Jeremy & Sass dive into what the evidence is showing us about the use of phenylephrine, ephedrine, and norepinephrine IV bolus doses. We talk about cerebral oxygen concentrations and cardiac output when administering these vasopressors, and ultimately ask ourselves…should we be less pushy?ReferencesKee W, et al.
