A Revolution in Surgery: Anaesthetics and Antiseptics
Surgery Before 1846: Speed Was Everything
Before anaesthetics, surgery in Britain was a last resort. Patients screamed; surgeons worked at speed because every second of pain risked shock. The London surgeon Robert Liston could amputate a leg in 28 seconds. Operations were limited to crisis cases — trauma, tumours visible on the surface, gallstones, amputations — because anything inside the body chest or abdomen meant near-certain death from pain, blood loss or infection. Most patients refused surgery until the alternative was definitely worse.
Three early anaesthetics changed surgery: nitrous oxide (Davy 1799), ether (Morton, Boston 1846) and chloroform (James Simpson, Edinburgh 1847). Simpson tested chloroform on himself and friends after dinner.
Simpson and Chloroform, 1847
James Simpson was an Edinburgh obstetrician searching for a better anaesthetic than ether, which irritated the lungs. In November 1847 he and two colleagues sniffed chloroform after dinner and woke up on the floor. Within days he was using it in childbirth. Chloroform was easier to administer and worked faster than ether, and it spread quickly across British surgery.
There was sharp opposition. Some clergy quoted Genesis 3:16 — ‘in sorrow shalt thou bring forth children’ — arguing that pain in childbirth was God’s will. Surgeons feared patients dying from the anaesthetic itself; in 1848 Hannah Greener, a 15-year-old, died under chloroform during a toenail operation. The objections were overcome partly by Queen Victoria, who used chloroform when she gave birth to Prince Leopold in 1853. Royal endorsement made chloroform respectable.
Anaesthetics encouraged surgeons to operate longer, deeper and on patients who would once have refused. But operating theatres were filthy. Surgeons wore unwashed coats stiff with old blood, used unsterilised instruments and worked in wards crowded with infected patients. Post-operative infection — gangrene, sepsis, ‘hospital fever’ — killed up to 50% of surgical patients. Surgeons called these years the ‘Black Period’: more operations, more deaths. Anaesthetics had solved the pain problem and exposed an infection problem the older system had hidden behind speed.
Lister and Carbolic Acid, 1865–1867
Joseph Lister was a Glasgow surgeon who read Pasteur’s germ theory in 1864. If germs in the air caused decay, Lister reasoned, they must also cause wound infection. Carbolic acid was already used to deodorise sewage in Carlisle. Lister tried it on a compound fracture in August 1865: he soaked dressings in carbolic and rinsed instruments and hands with carbolic solution. The wound healed without infection. He published his results in The Lancet in March 1867. Antiseptic surgery — killing germs during surgery — had begun.
Lister’s carbolic spray cut amputation deaths from around 46% to 15% in his Glasgow ward by 1869. Yet many British surgeons rejected his system into the 1880s — the spray was unpleasant, results were variable in untrained hands, and surgeons could not see the germs Lister claimed to be killing.
From Antiseptic to Aseptic Surgery
Lister’s carbolic system killed germs during surgery. By the 1890s a better idea had taken hold: stop germs reaching the wound in the first place. Aseptic surgery meant sterilising instruments in steam autoclaves (1880s), wearing surgical gowns and face masks, scrubbing hands before operating and using rubber gloves — introduced by William Halsted in Baltimore in 1889 after the antiseptics in his theatre cracked his nurse’s hands. By 1900 most British operating theatres were aseptic rather than antiseptic, and infection rates had fallen sharply.
Industrial-scale shrapnel wounds in the trenches forced surgical innovation. Röntgen’s X-rays (1895) became routine in field hospitals from 1914 to locate metal fragments. Blood transfusions, made possible by Karl Landsteiner’s identification of blood groups (1901), saved lives at the front by 1916. Surgeons learned to debride wounds — cut away dead tissue before infection set in. Plastic surgery began with Harold Gillies treating facial injuries at the Queen’s Hospital, Sidcup. War accelerated changes that peacetime medicine would have taken decades to adopt.
Linking to the Factor Essay
Anaesthetics and antiseptics show science and technology driving change — Pasteur’s germ theory was the precondition for Lister’s breakthrough, and chemistry produced the carbolic. The role of the individual matters too: Simpson and Lister both pushed personally against opposition. Religion resisted chloroform on biblical grounds. Chance appears in Simpson’s after-dinner experiment. War accelerated the spread of antiseptic and aseptic surgery from 1914. The strongest factor essays note that no single factor explains the whole story: science enabled it, individuals pushed it, religion slowed it, war broadcast it.
