Did you know that before anaesthesia was discovered, surgeries were performed on fully awake patients who were held down by force with assistants restraining them, while screaming in pain?
The surgeon would then work as fast as humanly possible. The quicker the operation, the higher the chance the patient might survive the shock.
The history of anaesthesia isn’t as straightforward as we know it. Most of what we read comes from Western accounts, but the truth is, people across the world were trying to ease pain long before the first ether bottle was opened in Boston.
Japanese surgeon Seishu Hanaoka had already cracked it — almost forty years earlier. He spent decades experimenting with herbs and came up with a mix that could put patients into deep, reversible sleep. He performed major surgeries without pain, long before the West even dreamt of ether or chloroform.
Even before that, there are scattered stories — monks in medieval Europe brewing herbal sedatives in monastery gardens, ancient Indian and Chinese texts describing mixtures that dulled pain. Some worked, some didn’t. But the idea was always there: pain could be controlled.
Then came 16 October 1846, the day everything changed. At Massachusetts General Hospital, William Morton used ether during surgery — and for the first time, the patient didn’t scream. The news spread fast and within weeks, surgeons in England tried it too.
Before that, surgery was nothing short of torture. Patients were strapped down, surgeons worked as fast as they could, and survival often depended on luck. After ether, everything changed. Surgery slowed down and it became precise.
A year later, James Simpson in Edinburgh started using chloroform — easier to give, but far riskier. Still, it spread across hospitals everywhere. Over time came local anaesthesia, spinal blocks, nerve blocks, IV drugs, and muscle relaxants — each making surgery safer and smoother.
By the 1950s, halothane arrived which is much simpler and more predictable. The rest followed: better machines, better drugs, better training.
Today, anaesthesiologists do far more than “put people to sleep.” They manage pain, run ICUs, handle emergencies, and keep patients alive during the toughest surgeries. The mortality rate from anaesthesia in developed countries is now less than one in 250,000.
And that brings us to today. In modern medicine, we can hardly imagine a surgery, a procedure, or even the administration of medicine itself without anaesthesia. That’s how precise, important, and indispensable it has become. From medieval monks brewing herbs and terrified patients screaming on the table, to high-tech operating theatres with machines monitoring every heartbeat, the journey of anaesthesia shows just how far modern medicine and research have come.
