Thank you Pat for being part of this project to help part 1 exam learning! This would be a daunting experience for anyone and Pat did a great job under pressure to give us a well structured and knowledgeable answers to our questions. The topics and questions we lined up today were Stem 1 1. What is nitrous oxide? 2. What are the advantages of using nitrous oxide? 3. What are the disadvantages of using nitrous oxide? 4. How is nitrous oxide stored in hospitals? 5. What is Entonox? Stem 2 1. What ...

In this episode we dive into the basics of the immune system and how it is affected by anaesthesia. Additionally we discuss Covid19 as a way pf explaining some of the crucial elements of immunity to make it relevant to the most life changing event of our generation. *Correction: Angiotensin 2 receptor is not the ACE-1 receptor. ACE-1 receptor converts angiotensin 1 to angiotensin 2. ACE-2 receptor converts angiotensin 2 back to angiotensin 1. Please rate, post a review and subscribe! Check out h...

Hi everyone! In this episode we go through a trainee's practice SAQ about the cardiovascular changes in morbid obesity. We also have a detailed chat about the important aspects of obese patients perioperatively, intubation, extubation and some of the dilemmas we all face. Stan's model answer is ~ 27mins Stan's rule of 5s for SAQ answers is 5 teaching points and 5 reasons for each point to gain maximum marks for your answer! Please rate, post a review and subscribe!

Here is our deep dive into what exactly occurs to volatile washout in an anaesthetised person if cardiac output changes. Out of the textbooks we reviewed, only MILLER'S ANESTHESIA (thought by many to be the bible of anaesthesia) comments on exactly what occurs! In this episode we reveal what Dr Stan discovered by running his very own transparent simulations using Gasman. https://www.gasmanweb.com The cardiac output/washout analysis begins at approx 9mins 30seconds. Our parameters for wash-in and...

This is one of the more complex questions in anaesthesia! Here's the actual WHO definition that doesn't use the term morbid obesity but rather obesity class 1, 2 and 3. Obesity is frequently subdivided into categories: Class 1: BMI of 30 to < 35 Class 2: BMI of 35 to < 40 Class 3: BMI of 40 or higher. Class 3 obesity is sometimes categorized as “extreme” or “severe” obesity. NB LISTEN TO NEXT EPISODE FOR DEEP DIVE INTO THE EFFECT OF CARDIAC OUTPUT ON WASHOUT!!! Millers Chapter 20 Inhaled A...

You've probably performed a few RSIs in your anaesthesia practice. But have you though about all the techniques you do to make this inherently risky technique safer? In this episode we chat about the approach to the question from the April 2014 and September 2013 SAQ paper Describe the physiological basis of methods used to prevent hypoxaemia prior to intubation in a rapid sequence induction. Include any adverse effects of these methods. The exam paper https://networks.anzca.edu.au/d2l/le/conten...

In this Episode we discuss the effects of pregnancy on a patient's respiratory physiology. We step through the SAQ #3 from the 2019 feb/march ANZCA exam paper: Discuss the effects of pregnancy on the respiratory system that are relevant to the practice of anaesthesia. Include in your answer how these effects influence the conduct of anaesthesia. Respiratory changes during pregnancy affects: 1. Airway management 2. Pre-oxygenation 3. Ventilation 4. Lung mechanics 5. Uptake of inhalational agents ...

In this episode we tackle the SAQ, explain the changes on FRC that take place with the administration of anaesthesia. July SAQ paper 2005 question 16. https://networks.anzca.edu.au/d2l/le/content/7669/viewContent/86778/View This is an important core topic that requires a broad understanding of the 1) A definition and normal values 2) How to measure FRC 3) and how it changes with anaesthesia 4) functions of FRC I use a categorised answer of anaesthetic, surgical and patient factors to get a broad...

Control of breathing is one of the most practically useful subjects you will learn in respiratory physiology! In this video we go through the most interesting aspects, exam tips, structures and how it relates to our own practice. The particular SAQ we address is from the ANZCA 2006 February exam paper, question 10: List the physiological factors which increase respiratory rate and include a brief explanation of the mechanism by which each achieves this increase. https://networks.anzca.edu.au/d2l...
