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.

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?

Episode Summary
Point of care ultrasound (POCUS) assessments of the airway is simply awesome! By utilizing POCUS during our preoperative airway examination, we can now determine with a greater certitude the level of difficulty of a patient’s airway as well as locate anatomical structures (such as the cricothyroid membrane) and endotracheal tube positioning within the airway.
In today’s episode Jeremy and Mark go over basic ultrasound skills and then discuss the various POCUS airway assessments. They then discuss two POCUS techniques for locating the cricothyroid membrane and finish up with a discussion on how to determine where the endotracheal tube is positioned using POCUS. It most definitely is POCUS “Go Time”!

Episode Summary
Every fourth episode we will release a podcast where we ask and answer questions about an anesthesiology or pharmacological topic and we’ll call it ANESTHESIA Q&A. We do this to help our community solidify their learning! We also produce these episodes because nurse anesthesia students and practicing CRNAs are all engaged in answering questions whether it be on exams during anesthesia school or for CRNA recertification.
In today’s episode we focus on reversal medications for opioids, benzodiazepines, and neuromuscular blocking drugs…all medications commonly used in ICUs and during anesthesia practice. This is Anesthesia Q&A Round 4!

We all experience acute stress. Sometimes on a daily basis. In this episode Jeremy breaks down acute stress and talks about the anatomy and physiology of stress. He reviews a theory on how highly stressful situations can both physiologically and psychologically affect our thinking and performance. He also points out how a certain amount of acute stress is actually helpful.
Then Jeremy discusses the meaning of BVM and how breathing, body position, visualizing success, speaking positively and motivating oneself with a mantra can help us deal with acute stress and come out on top. Got stress? BVM it!

In Episode 15 of the Nurse Anesthesia Podcast, Jeremy and Sass dive into the pharmacological world of ketamine. They talk about all the anesthesia situations where it can be useful. They discuss the pharmacology of ketamine, appropriate dosing, what the current evidence really shows about its use with increased intracranial pressure, and how it is frequently used for analgesia. It really is the Swiss army knife of anesthetic meds!

In today’s podcast Jeremy and Mark review several anesthesia concepts that were covered in previous episodes…specifically Malignant Hyperthermia, Pulse Oximetry, and Adrenal Crisis.
As educators we know it’s important to revisit and review anesthesia concepts in order to help with long term memory retention. There’s actually a learning technique called
spaced learning (or spaced repetition) where information is reviewed at increasing intervals over time, instead of being crammed in a single session.
This method leverages the psychological spacing effect, where learning and retention are more effective when study sessions are spread out. And in the context of learning anesthesia concepts, spaced learning helps learners more efficiently memorize and deeply understand complex topics by reinforcing the material at various intervals, allowing for better long-term retention.
Also, since all CRNAs will need to recertify their credential in the future with the NBCRNAs new MAC questions…these episodes will help with that too!

In today’s episode Jeremy and Sass start by diving into normal physiologic function of the Hypothalamic-Pituitary-Adrenal (HPA) Axis. They then review how it’s regulated and the pathology/medications that can alter the HPA Axis. After that, it’s all about the adrenal glands, and Jeremy and Sass differentiate between Acute Adrenal Crisis and Adrenal Insufficiency. They talk about why chronic steroid use puts patients at risk for Adrenal Crisis and why cortisol is necessary for proper cardiovascular function and a whole lot more. This is definitely the nuts and bolts of “What you need to know”!

This is a special episode where Jeremy & Sass talk with the one and only Dr. John Nagelhout, PhD, CRNA, FAAN. They talk with him about what it was like when he first went to anesthesia school, his transition into academics, how he gathered a group of CRNAs together to write the very first Nurse Anesthesia textbook, and the thousands of lives he’s influenced with his pharmacology lectures.
There’s a reason we call him the “Grand Master of Nurse Anesthesia Education” and this is a piece of history you won’t want to miss!

Anesthesia induction agents are essential anesthesia medications that anesthesia providers need to learn about and understand so they can select the correct medication for the right patient/situation. The primary induction agents used in today’s anesthesia practice include: Propofol, Etomidate, and Ketamine…we refer to these as “The Knock Out Buch!”
Without a doubt, propofol is used more often than any other anesthesia induction agent.
In today’s episode, we talk about the pharmacokinetics, pharmacodynamics, mechanism of action, and clinical indications of each one of the anesthesia induction medications. Get ready, because this is an episode filled with key concepts and important information used for exams that is hard to find!

In this episode we highlight the various difficult airway algorithms and failed airway checklists developed by professional airway organizations. These tools used by anesthesia providers to develop their personal airway management plans and to help guide decision making in the event of a difficult or failed airway.

We’ve heard from a lot of anesthesia students, RNs, and CRNAs about how they want some question-and-answer episodes…so we’re here to deliver! This is the first Anesthesia Q&A, and we’re calling it Round 1 (ding! ding! ding!). What better way to start Anesthesia Q & A than with some respiratory anatomy and physiology.
We’ve had extensive experience writing questions for anesthesia students, CRNAs, and for national certifying exams. So put the gloves on, it’s time to jump into the ring and dive into some of the favored respiratory topics that are tested in anesthesia school and on national certification exams.

Episode Summary
Laryngoscopy and intubation are core skills that anesthesia providers need to perfect. In this episode Jeremy and Sass discuss some of the keys to direct laryngoscopy and intubation. They start by identifying the primary keys when preparing to perform a direct laryngoscopy called “SOAP ME”. They then discuss the keys used when actually performing direct laryngoscopy and intubating the trachea. Spoiler alert…it’s all about “Epiglotoscopy”!

Episode Summary
Jeremy and Mark begin this episode by discussing the history of anesthesia gases. They discuss how volatile agents work and why we actually call them “volatile agents”. They discuss the pharmacokinetics and pharmacodynamics, get into the mechanism of action and discuss those test heavy topics of Oil:Gas and Blood:Gas Partition Coefficients. Phew! They round it out by talking about both adverse effects and contraindications. This is a great discussion about some core medications used in current anesthesia practice!
