H20: Surgery and Anaesthetics

📖 The Three Problems of Surgery

😣 The Problem of Pain

Surgery Before Anaesthetics

• Patients were fully conscious and had to be held down by assistants during operations
• Speed was the surgeon's most valued skill - the fastest surgeons were the most sought after
• Robert Liston could amputate a leg in 28 seconds, but even he accidentally cut off an assistant's fingers and a spectator's coat during one operation
• Patients often died of shock from the sheer agony of the procedure
• Many patients chose to endure their condition rather than face the horror of surgery
• Operations were limited to surface procedures: amputations, setting broken bones, removing bladder stones

Early Anaesthetics: Nitrous Oxide and Ether

Nitrous Oxide (Laughing Gas):

• Discovered by Joseph Priestley in 1772
• Humphry Davy noted its pain-relieving properties in 1799, but it was not adopted for surgery
• Used as a party trick ("laughing gas demonstrations") by showmen like Gardner Quincy Colton
• In 1844, American dentist Horace Wells saw a demonstration and had a tooth extracted under nitrous oxide - he felt no pain
• However, nitrous oxide was difficult to control and a public demonstration by Wells in 1845 failed when the patient cried out

Ether:

• First used as an anaesthetic by William T.G. Morton in Boston, USA, on 16 October 1846
• Morton successfully removed a tumour from a patient's neck while the patient was anaesthetised with ether
• News of the success reached England by December 1846, and ether was first used in London by Robert Liston on 21 December 1846
• Liston amputated a leg in just 25 seconds - the patient felt nothing

🧪 James Young Simpson and Chloroform (1847)

Simpson's Discovery

• James Young Simpson (1811-1870) was a Scottish obstetrician and professor of midwifery at Edinburgh University
• He was searching for a better anaesthetic than ether, which had many drawbacks
• On 4 November 1847, he and two friends inhaled a new chemical - chloroform - at a dinner party and fell unconscious
• He quickly realised chloroform was a more effective and pleasant anaesthetic than ether
• He began using chloroform to relieve the pain of childbirth, which was highly controversial

Opposition to Anaesthetics

• Religious opposition: Some argued that the Bible (Genesis 3:16) said childbirth should be painful as God's punishment for Eve's sin. Using anaesthetics was "defying God's will"
• Medical opposition: Some doctors argued that pain was actually beneficial - it helped the body recover and surgeons could gauge the success of operations by patient reactions
• Safety concerns: Chloroform was genuinely dangerous - the death of 15-year-old Hannah Greener on 28 January 1848, who died during a chloroform-anaesthetised toenail operation, raised serious safety fears
• Military opposition: Army surgeons believed soldiers needed to be brave and endure pain

🦠 The Problem of Infection

The Danger of Post-Operative Infection

• After anaesthetics were introduced, surgeons attempted more complex operations inside the body
• But patients often died from infections acquired during surgery - the death rate actually rose in some hospitals
• Hospitals were filthy: surgeons operated in blood-stained coats, used unwashed instruments, and operated in unventilated rooms
• Up to 50% of amputation patients died from sepsis (blood poisoning)

Lister and Carbolic Acid (1865)

• As covered in H19, Joseph Lister applied Pasteur's germ theory to surgery by using carbolic acid to kill germs
• He introduced carbolic acid spray in the operating theatre, soaked bandages in carbolic acid, and washed instruments in it
• His death rate for amputations fell from 46% to 15%

From Antiseptics to Aseptic Surgery

🩸 The Problem of Bleeding

The Challenge of Blood Loss

• Bleeding was a major cause of death during and after surgery
• Paré had introduced ligatures in the 16th century, but they were slow and not always effective
• Surgeons needed a way to replace blood lost during operations - blood transfusion
• Early attempts at blood transfusion were mostly failures - patients often died after receiving another person's blood

Karl Landsteiner and Blood Groups (1901)

• In 1901, Austrian physician Karl Landsteiner discovered that human blood falls into different groups - initially three, later four (A, B, AB, and O)
• This explained why earlier blood transfusions had failed: if a patient received blood of the wrong type, their immune system would attack the foreign blood cells, causing a potentially fatal reaction
• Landsteiner won the Nobel Prize for Medicine in 1930 for this discovery
• Once blood groups were understood, safe blood transfusions became possible

WWI and Blood Banks

• WWI (1914-1918) created enormous demand for blood transfusions due to the massive number of casualties
• In 1914, the discovery that sodium citrate could prevent blood from clotting meant blood could be stored
• In 1915, Richard Lewisohn discovered that adding citrate and dextrose allowed blood to be stored for up to a month
• The first blood depot was established in 1917 by Oswald Robertson at a US Army base near the Western Front
• By 1918, blood transfusions were being used routinely on the battlefield
• After WWI, the first civilian blood banks were established: the first in London in 1922

📊 The Impact of Solving the Three Problems

⚔️ The Impact of War on Surgery

• Crimean War (1853-56): Highlighted the need for better wound care and nursing (Florence Nightingale)
• American Civil War (1861-65): Advanced amputation techniques and field hospital organisation
• WWI (1914-18): Developed blood transfusion, improved treatment of burns and fractures, advanced brain surgery (Harvey Cushing), and developed reconstructive surgery (Harold Gillies - "father of plastic surgery" - treated facial injuries at Sidcup)
• WWII (1939-45): Advanced penicillin production, improved burns treatment (Archibald McIndoe at East Grinstead), and developed mobile surgical units

❓ Practice Questions

✅ Answers

1. Surgery was dangerous before anaesthetics because patients were fully conscious and felt every cut. They often died of shock from the pain. Surgeons had to work as fast as possible (Liston amputated a leg in 28 seconds), meaning operations were rough and inaccurate. Patients were unwilling to undergo surgery, so only life-threatening conditions were treated.
2. Opposition to chloroform came from several sources: religious opposition based on the Biblical argument that childbirth pain was God's punishment for Eve's sin; medical opposition from doctors who believed pain helped recovery; safety concerns after Hannah Greener's death in 1848 from chloroform during a minor procedure; and military opposition from army surgeons who believed soldiers should bravely endure pain. Queen Victoria's use of chloroform in 1853 helped overcome this opposition.
3. Landsteiner's discovery of blood groups (A, B, AB, O) in 1901 explained why earlier transfusions had killed patients - mismatched blood caused fatal immune reactions. By matching donor and recipient blood groups, transfusions became safe. Group O was identified as the universal donor, meaning it could be given to any patient in an emergency.
4. Antiseptic surgery (Lister) involved killing germs on wounds and instruments using carbolic acid. It was effective but imperfect because germs could still enter from the air or the surgeon's hands. Aseptic surgery went further by preventing germs from entering the wound at all, through sterilised instruments, clean operating theatres, rubber gloves, and sterile gowns. Aseptic surgery was more effective because it addressed the root cause - preventing contamination rather than just treating it.
5. A balanced answer should discuss all three problems: pain (anaesthetics allowed longer, more complex operations but didn't prevent infection or bleeding); infection (killing germs was crucial because more operations led to more infections after anaesthetics were introduced); bleeding (blood transfusions allowed patients to survive major surgery). A strong answer would argue that solving infection was arguably most important because it addressed the highest cause of surgical death, or that all three were interdependent.
6. WWI advanced blood transfusions by creating urgent demand due to massive casualties. The discovery that sodium citrate prevented clotting (1914) meant blood could be stored. Oswald Robertson established the first blood depot near the Western Front in 1917. The techniques developed during wartime proved that large-scale transfusion was practical and saved thousands of lives, leading to civilian blood banks after 1918.

🎯 Exam Tips

• Always use specific dates: Simpson 1847, Lister 1865, Landsteiner 1901
• Remember the three problems framework: Pain, Infection, Bleeding - it's an excellent way to structure answers
• Explain why solving one problem sometimes made another worse (e.g. anaesthetics led to more operations, which led to more infections)
• Use the named examples: Hannah Greener, Queen Victoria, James Greenlees, Oswald Robertson
• Link war to medical progress - WWI is essential for blood transfusions
• For evaluation questions, show how the three problems were interdependent
• Don't forget the role of technology (steam sterilisers, citrate storage) alongside individual discoveries
