GasGasGas - Anaesthetic Science for Anaesthesia!
An anaesthesia podcast focusing on the scientific knowledge anaesthetists should know, tracking the UK Primary FRCA Curriculum. Each episode delivers a treatise on a drug, concept, or practice critical to passing the FRCA Primary Exam, with natural tangents to keep it engaging. Relevant to anyone interested in pharmacological, physiological, clinical, physical, and chemical concepts in anaesthesia. Notes are available on the podcast's website.

Vasopressin and its pals
We tumble into a flatspin at 35000 ft, the landing gear is of no use, so you reach for vasopressin instead of the ejector seat. But how can it remediate this situation, should you look for DDAVP instead? Or was it a Terlispin!
Have I seen TopGun recently, is this a seriously intriguing episode on vasopressin and its mates that will put your brain into a nose dive?
All possible, you will have to li

Specifically : Comparisons between the blood gas partition coefficient their oil gas partition coefficient the boiling points and saturated vapour pressure differences and we’re going to define those two points a little bit and then also th
MAC & Blood:Gas Coefficients: Volatile Anaesthetic Pharmacology
Today we're covering more volatiles, thinking a bit more about the defining characteristics of volatiles and exploring MAC, Minimum alveolar concentration.
Including MAC BAR and MAC Awake - and what you really need to aim for to make sure no one remembers having their insides rummaged about in by a surgeon!

Thiopentone: Barbiturate Anaesthesia, does it still have a place?
Talking Thiopentone, the bits needed for the exam and the practical bits of when it might get used (rarely, unless the boss happens to be from the 1940's) or you're doing obstetrics.

Gas Gas Gas - Compartmentalised Volatiles and a brief jaunt with Sevoflurane
This episode explores how volatile anaesthetics behave and affect patients. Chiefly thinking about how the compartments in a breathing circuit and patient interplay to achieve depth / maintain anaesthetic depth and emerge from anesthesia.
Absolutely worth a listen to get your head around compartments and also starting thinking about blood gas and oil gas partition coefficients

Hepatic Clearance: A key principle in anaesthesia
This primary FRCA podcast episode introduces clearance and then descends into bedlam trying to think about how the liver really clears drugs on a kinetics level.

I am not making you run for the hills by talking phase 1 and 2 metabolism, CYP and all that jazz, that's for a later episode.
