If you like a story about tenacious testicular traction and slamming shins then this is the episode for you. 

This FRCA Primary Podcast episode explores cocaine and the exposure patients have to it in the clinical environment, chiefly courtesy of the ENT surgeons. The episode explores mechanism, side effects, onset, implications, but also the history of spinal anaesthesia and treatment of cocaine toxicity in the A&E department.

This FRCA Primary Podcast episode burrows into bupivacaine, exploring its friends (additives), mechanism of action, and clinical applications. We'll cover the key differences between neuronal and cardiac action potentials, and discuss why levobupivacaine has become the preferred choice in many clinical scenarios.

Opioids are a significant cornerstone of anaesthetic practice, forming part of the triad of anaesthesia with their analgesic properties. We utilise these analgesic properties not just because "surgery hurts," but also because our interventions cause physiological upset - laryngoscopy being a prime example.

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, we make our descent 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 into its final destination: the dorsal horn of the spinal cord, before it potters away to realms of mischief in the brainstem.

In this episode of Gas, Gas, Gas, we drill a figurative oil well into the pharmacology of diamorphine — also known by its more notorious street name, Heroin/Smack/Golden Brown. 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 (but sound advice I would argue) and exam-focus.

We are plunging into the pharmacology of oxycodone, a potent semi-synthetic opioid analgesic widely used in perioperative and chronic pain settings. We explore oxycodone's mechanism of action, pharmacokinetics, and pharmacodynamics

We dissect its action on mu-opioid receptors, compare it to morphine and other opioids, and review evidence regarding oral vs intravenous formulations, metabolism via CYP450 enzymes + implications for renal and hepatic impairment.

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…
