GasGasGas - Primary FRCA ’fun’
The Primary FRCA Podcast This will fit into a corner of your day, delivering a well explained concept critical to the knowledge required to pass the FRCA Primary Exam! This is relevant to anyone in the world interested in these pharmacological, physiological, clinical, physical and chemical concepts, naturally it is flavoured towards UK practice. Episodes will be (mostly) succinct, conceptually specific, and exam material focussed.

Remifentanil is an anaesthetist’s dream: ultra-short acting, reliably titratable, and deeply potent. This episode takes a dual-pronged approach—covering both the FRCA-relevant pharmacology of remifentanil and introducing the Minto target-controlled infusion (TCI) model.

In this explainer episode of GasGasGas, James delves into the joyful complexities of neuraxial opiate pharmacology. Why do we bother putting opiates into this space at all? What governs their journey, how do they behave once administered, and what clinical pearls can be drawn from their behaviour? This episode follows the journey of a single opioid molecule through the fatty labyrinth of the epidural space, across barriers, and int...
In this episode of Gas, Gas, Gas, we dive deep into the pharmacology of diamorphine — also known by its more notorious street name, heroin. Diamorphine is a synthetic diacetylated derivative of morphine, and this episode details its mechanism of action, clinical applications, pharmacokinetics, pharmacodynamics, and side effect profile. The episode is structured to support FRCA Primary revision with an irrelevant clinical anecdote (...
Episode Description: In this episode of GasGasGas, we a plunge into the pharmacology of oxycodone, a potent semi-synthetic opioid analgesic widely used in perioperative and chronic pain settings. Aimed at FRCA Primary candidates and anaesthetic trainees, this episode explores oxycodone's mechanism of action, pharmacokinetics, and pharmacodynamics, as well as its clinical indications, side effect profile, and relevance in anaesthesi...
In this episode of the GasGasGas Primary FRCA podcast, we explore methadone—its pharmacology (pharmacodynamics and pharmacokinetics), diverse receptor activity, and its clinical uses.
While traditionally associated with managing opioid dependency, methadone’s unique pharmacodynamics and potential utility may have been overlooked given its other uses…

In this episode of GasGasGas, we explore Alfentanil, a short-acting μ-opioid receptor agonist pivotal for anaesthetic practice. Discovered in 1976 by Janssen Pharmaceuticals, Alfentanil remains a super handy agent, especially for (modified) rapid-sequence inductions and acute pain management.

Welcome back to Gas, Gas, Gas—the podcast that breaks complex anaesthesia concepts into digestible, high-yield episodes. Today, we’re doing a deep dive into the TIVA Models for Propofol particularly the: Marsh, Schneider, and Eleveld TCI models.
This isn’t just academic—understanding the underpinnings of these models means you can dose more precisely, tailor your anaesthetic plan to the patient in front of you, and avoid the classi...
In this VivaCast episode, we simulate a comprehensive FRCA Primary physiology viva covering three key topics: physiological response to acute blood loss, nerve conduction and classification, and acid-base balance including pH regulation and anion gap interpretation.

Welcome to a special interview edition of GasGasGas – the podcast that explores anaesthetic life in all its glorious detail, venturing out into its terrifying, and deeply human dimensions.
I want those thinking about anaesthetics to gain insight, and I want everyone else Post IAC to remember the IAC experience and focus on what we can do to make IAC even better! Today, host James sits down with James, a CT2 ACCS anaesthetic traine...
In this VivaCast episode, we present a complex clinical scenario involving an intravenous drug user (IVDU) presenting with an infected pseudoaneurysm.
Tom grapples with the challenges of these high BBV risk cases and managed local anaesthetic toxicity as it all goes terribly pear shaped!

Tom experiences some catecholamine release of his own in this episode as he talks serpiginous GPCRs, Adenyl cyclase, PKA and comparing local anaesthetics, and getting tied up (like we all do) with the clinically pointless, but delightfully examinable Vaughan-Williams Anti-arrythmic classes!
