Time for round 2 with Pat are very generous trainee who's offered to be quizzed on our podcast. Here are the questions from this round: Stem 5 1.     How does heparin work? 2.     How about low molecular weight heparin? 3.     Why do we monitor unfractionated heparin but not low molecular weight heparin?   Due to lower binding to plasma proteins and to cell surfaces, the plasma anti Xa activi...

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 disad...

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 recepto...

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 p...

In this episode we talk about the main steps that facilitate gas exchange at the placenta.  This is great applied respiratory physiology and a common question in the viva and SAQs!

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...

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 LI...

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....

This is one of the most common dilemmas that will arise during your anaesthesia practice! In this episode we will step through the ANZCA part 1 SAQ, Q9 from 2014 September https://networks.anzca.edu.au/d2l/le/content/7669/Home?itemIdentifier=D2L.LE.Content. ContentObject.

In this episode we delve into lung compliance! We chat about the 2020 aug/sep SAQ Q3: Discuss respiratory system compliance and outline factors that affect it. We also go into how to use this theoretical knowledge to improve ventilation of patients with poor static or dynamic compliance and high ventilating pressures in pneumoperitoneum. Some basic resources: https://en.wikipedia.org/wiki/Hysteres...

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...
