The History of Anaesthesia: How Did Doctors Perform Surgeries Before Modern Painkillers?

Have you ever wondered how patients endured pain during surgery in the old days? We are talking about days when anaesthesia was not even invented. From ancient herbal remedies to sophisticated medical science, the journey of conquering surgical pain spans thousands of years. Today, we will explore the fascinating history of anaesthesia. 

Timeline: A Look Into The History of Anaesthesia

Based on historical records from the Wood Library-Museum and the World Federation of Societies of Anaesthesiologists, here’s a timeline of events that led to the invention of modern anaesthesia. 

Ancient Remedies

(4000 BCE - 1600 BCE)

Around 4000 BCE, Sumerian artifacts provided the earliest known depictions of the opium poppy. They were used for its medicinal effects. By 2250 BCE, Babylonians were actively using henbane to relieve severe toothaches. Later, around 1600 BCE, ancient Chinese civilizations started practicing acupuncture as documented by Shang Dynasty pictographs.

Early Chemistry

(1540 - 1659)

The German physician and botanist Valerius Cordus successfully synthesised diethyl ether in 1540. He originally called it the ‘sweet oil of vitriol’. Over a century later in 1659, Sir Christopher Wren and Robert Boyle pioneered intravenous therapy. This was achieved by them by injecting opium through a goose quill directly into a dog's vein.

Gases and Extracts

(1771 - 1805)

Between 1771 and 1786, the English chemist Joseph Priestley made the discovery of nitrous oxide and isolated oxygen. Building on this work in 1800, Humphry Davy observed that nitrous oxide can destroy physical pain. 

Davy brilliantly suggested it can be used advantageously during surgical operations. In 1804, Japanese surgeon Hanaoka Seishu formulated a highly effective oral herbal anesthetic known as Tsusensan. This reproducible technique allowed him to perform painless major surgeries decades before Western medicine adopted similar practices. Shortly after, in 1805, pharmacist Friedrich Sertürner isolated a powerful new substance from opium. He named it ‘morphium’.

The Ether Era Begins

(1846)

William Morton and surgeon John Warren staged the first public demonstration of modern ether anesthesia in Boston on October 16, 1846. That same year, by December 19, ether anesthetics were successfully administered during surgeries in both Dumfries and London. These momentous events changed surgery from a terrifying, agonising last resort into a careful, calculated medical procedure.

Chloroform and Local Anesthetics

(1847 - 1877)

James Simpson introduced chloroform as a more potent, riskier, alternative to ether in In November 1847. The next major leap in pain management happened in 1877 with the introduction of cocaine as a local anesthetic. This innovation finally paved the way for modern local infiltration and spinal block techniques.

Modern Anesthesiology Takes Shape

(1920s - 1950s)

Throughout the 1920s and 1930s, doctors perfected the use of tracheal tubes to properly control a patient's breathing during operations. In 1943, Dr Harold Griffith revolutionised the field again by introducing curare as a muscle relaxant in clinical anesthesia. 

This allowed surgeons to operate on a relaxed abdomen without using dangerously deep levels of inhaled anesthetics. Later, in the mid-1950s, the introduction of halothane gave a much safer and easier inhalational agent for the growing medical specialty.

Today, anesthesiologists are highly trained physicians who utilise these centuries of innovation to ensure patient safety across a wide range of medical procedures.

Conclusion

From ancient herbal remedies to modern chemical agents, the evolution of anaesthesia is a most remarkable triumph in medical history. It has conquered the agony of the operating table. These crucial discoveries changed surgery from a terrifying ordeal into a safe, calculated science. Today's highly trained anaesthesiologists continue to build upon this centuries-old legacy, making sure that complex medical procedures remain both painless and life-saving.
