Count to 10 - Anaesthetic Primary Podcast

Dive into the intriguing world of pain physiology, where sensory pathways and the transition from acute to chronic pain are dissected. Explore the different types of pain, including visceral and somatic experiences, especially during labor. Discover how neuropathic pain differs and how pain perception can change as we age. With a focus on practical insights and exam strategies, this discussion simplifies complex concepts, making the challenging aspects of pain easier to navigate.

The discussion dives into the fascinating world of neurophysiology, focusing on intracranial pressure (ICP) and cerebral blood flow (CBF). Key concepts include the Monro-Kellie Doctrine and how ICP is measured. The host explains Cushing's reflex and emergency management strategies. Listeners will learn about the interplay between CO2, O2, and CBF, as well as how anesthetic drugs influence these dynamics. Spinal cord perfusion is also covered, emphasizing its continuous link to brain physiology, alongside practical insights for exam preparation.

Dive into the fascinating world of nerve conduction physiology and the essential differences between sleep and general anaesthesia. Explore how EEG measures brain activity, examining various processed types like BIS and entropy. Gain insights into sleep architecture and its systemic effects, alongside expert tips on tackling past exam questions related to these complex subjects. Perfect for anyone looking to deepen their understanding of neurophysiology and pain!

Dive into the intricate world of neurophysiology and pain as the discussion kicks off with the autonomic nervous system's structure and function. Learn how sympathetic and parasympathetic systems operate, along with their key neurotransmitters. The blood-brain barrier's anatomy and its critical roles in selective permeability are explored, alongside the production and dynamics of cerebrospinal fluid. To cap it off, insightful exam-style questions are tackled, making this a must-listen for aspiring professionals.

In this lively discussion, trainee anaesthetist Nic showcases his exam skills while being evaluated by special guest Celia, an experienced examiner. They delve into essential topics like the components and storage of blood products, the mechanisms of opioids, and the intricacies of thermoregulation. Nic explains how the body senses temperature and compares non-invasive vs invasive blood pressure measurement techniques. The pair wraps up with constructive feedback, highlighting Nic's strengths while identifying areas for improvement, all in a supportive learning atmosphere.

Today's episode is huge!! I go through all the little things not covered in PK or PD with regards to general pharmacology. First, I go through broadly drug preparation and packaging within pharmaceutics (01:18) followed by isomerism (08:11). Then I move on to drug variability starting off with some definitions (19:05) and then moving on to changes in PD and PK among different physiological states (22:47) and pathological states (38:29). Lastly, I look at a classification for adverse drug reactions (44:20). As always, I finish with a look at the past SAQs (48:13). There were so many to go through here! Thanks for listening! As always if you have any feedback let me know

This informative discussion is a must for anyone aiming to grasp the essentials of drug administration in clinical practice.

Dr. Anthony Haidt, an esteemed primary exam examiner and anesthesia specialist, joins to explore the complexities of propofol pharmacokinetics and Target Controlled Infusion (TCI). He breaks down vital equations and utilizes analogies, like a bucket analogy, to clarify rate constants and drug compartment models. The conversation covers age and weight variations in anesthesia dosing, practical applications for clinicians, and the significance of understanding the Marsh and Eleveld models in patient safety. It’s a must-listen for anyone looking to deepen their anesthesia knowledge!
