Why study the History of Anaesthesia?
• An understanding of our past guides our future
• The history of surgery is inextricably linked to the development of appropriate anaesthetic techniques and so the history of surgery follows the history of anaesthesia
• We are all part of it
History of Anaesthesia
• Pre-1846 - the foundations of anaesthesia
• 1846 - 1900 - establishment of anaesthesia
• 20th Century - consolidation and growth
• 21st Century - the future
Pre 1846 - The Foundations of Anaesthesia
……..so the Lord God caused him to fall into a deep sleep. While the man was sleeping, the Lord God took out one of his ribs. He closed up the opening that was in his side……...
Genesis 2:21 NIrV
The Foundations of Anaesthesia
• Drug methods– Alcohol
– Opium (poppy)
– Hyoscine (Mandrake)
– Cannabis (Hemp)
– Cocaine (New World)
• Non-drug methods– Cold
– Concussion
– Carotid compression
– Nerve compression
– Hypnosis
– Blood letting
The Foundations of Anaesthesia
• Status of surgery– Barber shop surgeons
• Types of surgery– Amputations & dental
extractions– No antisepsis – Appalling mortality
• Indications– Unbearable pain– Crippling deformity– Imminent death
“…the case was an interesting one of a white swelling, for which the thigh was to be amputated. The patient was a youth of about fifteen, pale, thin but calm and firm. One professor felt for the femoral artery, had the leg held up for a few moments to ensure the saving of blood, the compress part of the tourniquet was placed upon the artery and the leg held up by an assistant.The white swelling was fearful, frightful. A little wine was given to the lad; he was pale but resolute; his Father supported his head and left hand. A second professor took the long, glittering knife, felt for the bone, thrust the knife carefully but rapidly. The boy screamed terribly; the tears went down the Father’s cheeks. The first cut from the inside was completed, and the bloody blade of the knife issued from the quivering wound, the blood flowed by the pint, the sight was sickening; the screams terrific; the operator calm….”
Contemporary description of surgery, 1841
Industrial and Scientific Revolution
• 1540: synthesis of ether• 1628: circulation of blood
• 1744: ether inhalation suggested to treat pain
• 1770’s: research on CO2
• 1771: discovery of O2
• 1772: “Mesmerism”
• 1773: discovery of N2O
• 1794: gas therapy in illness
• 1709: iron formed from coke• 1712: first steam engine• 1733: flying shuttle• (1745: Battle of Culloden)• 1769: water frame• 1769: Watt steam engine• 1771: cotton mills
• 1779: first iron bridge• (1789: French Revolution)• 1801: first steam carriage
Industrial and Scientific Revolution
• Late 1700’s– lots of new gases identified– attempts to apply gas knowledge to medicine– directed at treatment of existing diseases
rather than novel use
• Gases of importance– nitrous oxide– ether– carbon dioxide– oxygen
Gas Therapy in Illness • Pneumatic Institute, Dowry Square, Clifton, Bristol
• founded by Thomas Beddoes (1760-1808) in 1794 with equipment designed by James Watt (1736-1819)
• attempted to use used gas therapy (incl. oxygen, nitrous oxide & ether) to treat diseases incl. asthma, dropsy, consumption, & venereal disease
Pneumatic Institute
New medical institution.Upper end of Dowry-Square, Hotwells, corner house. Treating incurable diseases.Medical professors at Edinburgh.Many Physicians in England.Consumption, Asthma, Palsy, Dropsy, obstinate Venereal Complaints, Scrophula or King's Evil.Other incurable diseases.Patients treated gratis.Expectation: Considerable portion of cases will be permanently cured.Methods are not hazardous or painful. Attendance will be given from 11 till 1 o'clock by Thomas Beddoes or Humphrey Davy. Subscriptions for support of Institution received by John Savery, Esq., Narrow Wine Street, Bristol.
Bristol Gazette March 21 1799
Pneumatic Institute
Humphrey Davy (1778-1829)
• became Superintendant in 1798
• continued Priestley’s and Beddoe’s Work
• Nitrous oxide & Ether
Humphrey Davy & the Pneumatic Institute
• Recognised analgesic properties of N2O and christened it “laughing gas”
• first tentatively suggested a use during surgery“…as nitrous oxide in its extensive operation
appear capable of destroying physical pain it may be used with advantage during surgical operations in which no great effusion of blood takes place …”
Nitrous oxide
• 1800: Davy’s thesis
• 1834: Colton “anaesthetised” 6 Red Indians by mistake
• 1844: Horace Wells had his own tooth pulled under N2O - “a new era in tooth pulling”
• 1845: Wells “failed” to demonstrate N2O at MGH
Ether• 1540: synthesised and named “sweet oil of
vitriol” by Valerius Cordus
• renamed “ether” by Frobenius
• 1744: Matthew Turner published essay suggesting its inhalation in certain types of pain
• late 1790’s: research at Pneumatic Institute
Ether
• 1821: Benjamin Brodie (1783-1862) demonstrated to Royal College of Surgeons that ether inhalation could induce insensibility in a guinea pig - “….ether acted like a narcotic poison……”
Ether
• 1842: first use as clinical anaesthetic in USA
• 16th October 1846: first public demonstration of ether anaesthesia in Boston, Mass.
• William T G Morton“Inventor and Revealer
of Inhalational Anaesthesia: Before Whom, in All Time, Surgery was Agony; By Whom, Pain in Surgery was Averted and Annulled; Since Whom, Science has Control of Pain.”
So why no anaesthesia until 1846?
• Why did Davy not pursue his work?
• no real concept of “anaesthesia” in late 1700’s / early 1800’s how can you achieve a state which you assume impossible or cannot envisage achieving
• Pneumatic Institute concerned with treatment of disease by “Physicians” - surgery did not have same standing and therefore influence
• State of surgery - almost inevitably fatal - why encourage them?
• General moral / religious beliefs and fear / concerns about animal experimentation
• Born at Lady Halton, Bromfield, Shropshire
• matriculated at Edinburgh University 1819
• attended lecture “On Asphyxia” by Henry Goldwyer - “a temporary suspension of the vital functions arising from a deficiency of atmospheric air..” and described reversal using artificial respiration & electrical restarting of heart
• admitted as member of RCS London 1820
• set up practice in Ludlow, Shropshire
Henry Hill Hickman and carbon dioxide
• 1821-1824: series of experiments on small animals to induce “suspended animation”
• semi-asphyxiation due to air starvation or by breathing Carbonic Acid (CO2) gas
• after unconsciousness was induced Hickman operated on them - amputations, removal of ears, skin incisions - and observed responses to surgery, evidence of pain, amount of bleeding and time to recovery
• 1824: attempted to bring work to notice of Royal Society
Henry Hill Hickman
“……there is not an individual who does not shudder at the idea of an operation however skillful the Surgeon or urgent the case, knowing the great pain that the patient must endure, and I have frequently lamented, when performing my own duties as a Surgeon, that something has not been thought of whereby the may be tranquillised and suffering relieved …..I have been induced to make experiments on Animals, endeavouring to ascertain the practicability of such treatment on the human subject……I have witnessed results which show that it may be applied to the animal world , and ultimately I think will be used with perfect safety and success in Surgical operations…..I have never known of a case of a person dying after inhaling Carbonic Acid gas if proper means were taken to restore the animal powers …..”
Henry Hill Hickman
Henry Hill Hickman• 1824: moved to
Shifnal
• 1824: “A Letter on Suspended Animation” (W Smith, Ironbridge, 1824) to TA Knight of Downton Castle
Henry Hill Hickman
• 1825: having failed to attract attention of Knight, Davy and Royal Society wrote to Shrewsbury Chronicle (dated 3rd June)
• Anonymous writer (“Antiquack”) responded to “Letter on Suspended Animation” and Shrewsbury Chronicle article in The Lancet 1825
Henry Hill Hickman
• “…can he for a moment suppose that any medical man of sense and judgement will be so far led away by a proposal so utterly at variance with all he has ever heard, saw, or read, of the deleterious effects of respiring the fixed air to believe that that this letter was published with any intention of benefiting mankind... intended to serve as a decoy by which credulous may be induced to give up their senses as well their cash to men…”
• “…an open and downright quack is superior to a plausible quacking physician… “
Henry Hill Hickman
• “…I sincerely hope, and believe, for the credit of the profession, be utterly impossible to find any surgeon so great a fool, and so unwarrantably bold as to undertake that operation on such terms..”
• “…I do fervently hope that the letter itself may be a complete hoax, and not written by Dr Hickman; for, in this age of science and gentlemanly acquirement, I feel assured, that no man who has any claim to the honourable appellation of a Doctor of Physic would so far disgrace both his profession and himself by writing such a tissue of quackery, which he himself, and every medical man must know is (to say the least) humbug”
signed Antiquack, The Lancet 1825
Henry Hill Hickman
• 1828: appeal to Charles X of France - referral to Royal Academy of Medicine in Paris
• 1829: returned to practice in Tenbury Wells, Shropshire
Henry Hill Hickman• 1847: letters in Lancet by
Thomas Dudley of Kingswinford identifying Hickman’s work with reports of “the Letheon”

1846-1900
• General Anaesthesia– Ether
• spread to Europe
– Nitrous oxide
– Chloroform• James Young
Simpson• John Snow
• Local Anaesthesia– anaesthesia
without sleep
• New techniques– early landmarks
Ether
• 16th October 1846: first public demonstration of ether anaesthesia in Boston, Mass.
• “Gentlemen this is no humbug. We have seen something today that will go round the world”
Ether - the news spreads
• Letter and other papers from Jacob Bigelow (description of his daughters surgery under ether and relevant copy of Boston Daily Adveriser) sent to Francis Boott in London
• News carried by Cunard paddle steamer “Acadia” leaving Boston 3rd Dec 1846 and arriving Liverpool 16th Dec 1846
Ether - the news spreads• 17th Dec 1846: Boott received letter and
arranged with dentist James Robinson to experiment with ether inhalation
• 19th Dec 1846: ether administered by James Robinson to a Miss Lonsdale for molar extraction at Boott’s home
• 21st Dec 1846: Robert Liston, Professor of Surgery at University of London publicly amputated the leg of Frederick Churchill at UCH - “This Yankee dodge beats mesmerism hollow”
Ether - the Dumfries connection
• William Fraser– Cunard Ship’s surgeon
• 19th December 1946– ? 1st European use of
Ether anaesthesia
• What case?– probably an
amputation of a leg in a patient run over by a cart - patient died
Ether - the news spreads• 1847: arrival of Ether
Anaesthesia announced in first edition of “The Lancet” of 1847
• Letter from Francis Boott
• Letter to Boott from Henry Bigelow
• Paper from Boston Medical and Surgical Journal
• Robert Liston’s own experiences
Ether - the news spreads• 1847: Liston became an increasingly important
supporter of ether in the following months at a time when many surgeons tried, then abandoned its use returning to practice without anaesthesia
• Reasons for possible abandonment– attempts to “patent” anaesthesia and so limit its use– inadequate anaesthesia – excessive secretions – vomiting patients– risk of explosion and fire (candlelight!)– perceived “risks” of rendering patient unconscious for
surgery
Nitrous oxide
• 1847: Horace Wells published paper “A History of the Discovery of the Application of Nitrous Oxide Gas, Ether and Other Vapours to Surgical Operations”

• Tried chloroform on himself and friends at suggestion of David Waldie, a chemist
• Secured and popularised chloroform as clinical anaesthetic, esp. in Obstetrics
James Young Simpson
• many objections to analgesia for childbirth
• religious and moral
• Genesis 3:16 - “…..The Lord God said to the woman, I will greatly increase your pain when you give birth. You will be in pain when you have children. You will long for your husband. And he will rule over you……..”
Chloroform
• 1847: John Snow’s regulating inhaler

• became interested in anaesthesia via work in toxicology
• apprenticed in Newcastle, then worked in London 1836-1858 until his death
• acknowledged as “first full-time” anaesthetist developing ways to improve methods of ether and chloroform administration
John Snow (1813-1858)
John Snow• “Chloroform a la Reine”
• Prince Leopold– born 7th April 1853
• Princess Beatrice – born 14th April 1857
• helped to overcome religious and moral objections to analgesia for childbirth
“….administered Chloroform to the Queen in her confinement…. Dr. Locock was sent for about nine o'clock this morning, stronger pains having commenced, and he found the os uteri had commenced to dilate a very little. I received a note from Sir James Clark a little after ten asking me to go to the Palace. I remained in an apartment near that of the Queen……………. At a twenty minutes past twelve by a clock in the Queen's apartment I commenced to give a little chloroform with each pain, by pouring about 15 minims by measure on a folded handkerchief……. Her Majesty expressed great relief from the application, the pains being very trifling during the uterine contractions, and whilst between the periods of contraction there was complete ease. The effect of the chloroform was not at any time carried to the extent of quite removing consciousness. Dr. Locock thought that the chloroform prolonged the intervals between the pains, and retarded the labour somewhat. The infant was born at 13 minutes past one………..consequently the chloroform was inhaled for 53 minutes. The placenta was expelled in a very few minutes, and the Queen appeared very cheerful and well, expressing herself much gratified with the effect of the chloroform…”

– more TCI
– “closing the loop” techniques
– new airway management techniques
– new monitoring - anaesthetic depth
Anaesthesia in the 21st Century
• Staffing and workload issues– increased demand for “anaesthetic services”
– questioning of roles outside theatre
– questioning of roles within theatre
Anaesthesia in the 21st Century
• Staffing and workload issues– development of non-medical anaesthetist
– pilot sites up and running– how best to integrate with “medical
anaesthesia”– who to recruit
» nurse-based» postgraduate science-based» other background
– already raising a number of other training & service issues
Anaesthesia in the 21st Century
The future of Anaesthesia is assured - but we may see our roles and how
we practice it change
