Episode notes
Origins Of Ether Anaesthesia
- Dr Gas Lurks recounts early ether anaesthesia history from Crawford W. Long to William T.G. Morton.
- These stories show how accidental inhalation discoveries led to rapid worldwide adoption of ether for painless surgery.
Ether's Potent But Slow Pharmacology
- Ether is a small, highly soluble volatile with a low MAC but very high blood:gas solubility, slowing onset and recovery.
- Its oil:gas solubility is high, explaining strong potency despite slow kinetics.
Microwave Sterilisation Mishap
- Dr Gas Lurks shares a personal microwave sterilisation mishap that blasted the microwave door open.
- He uses it to illustrate a mechanical explosion from trapped steam and pressure.
