Episode 10: John Nagelhout – The Grand Master of Nurse Anesthesia Education

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.

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!ReferencesAleksandrova LR, et al.

In this episode Jeremy and Mark focus on the cricothyroid membrane. They discuss the anatomy, sizing, vasculature and orientation of this important airway landmark. They then highlight techniques for palpating the cricothyroid membrane, and finish up with a discussion that explains how to use Point of Care Ultrasound (POCUS) to mark where exact position of this membrane is on the neck.

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! ReferencesBruder EA, Ball IM, Pickett W. 2015.

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”! References1. Bruder EA, Ball IM, Pickett W. 2015.

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!About The Nurse AnesthesiaFor anyone who wants to learn or review anesthesia concepts…we will set you up for a successful educational jOURney by providing short, meaningful courses to accelerate your nurse anesthesia learning, tackle your training, and become the successful CRNA you have always dreamed of.

Episode SummaryThe pulse oximeter is a primary anesthesia and critical care monitor. Not only does it help identify hypoxemia, but it provides several other pieces of essential information when monitoring a patient during anesthesia and surgery. In this episode, we go over how the pulse oximeter functions, the current advantages and disadvantages, and other practical considerations that make pulse oximetry monitoring simple awesome!ReferencesWilkins MC.
