  1. 6: The Depth of the Problem

    Over sixty years after the discovery of chloroform anaesthesia, doctors would finally get a conclusive answer about its risks. And as we head towards the 200th anniversary of William Morton’s ether demonstration, new problems with the modern inhaled anaesthetics we use are being debated.…

  2. 5: The Commissions

    Chloroform could stop patients breathing if you accidentally gave too much, but could it also cause the heart to suddenly stop beating? John Snow thought it did, but doctors in Scotland disagreed. Through the second half of the 19th century, the commissions and committees that investigated...

In the mid 19th century, scientists were discovering new gases, and new ways to experiment with them, but the origins of anaesthesia don't...

    Ether/Or is about the discovery of anaesthesia, and all its advantages. But it's also about the many problems that came with it. From failed attempts to fatal consequences, the introduction of anaesthesia in 1846 was a major leap forward for medicine and surgery. But it forced doctors and…
