The History of Therapeutics • The ups and down of blood-letting therapy • The origin and development of surgery
The ups and down of bloodletting • The therapy of Bloodletting (phlebotomy) began before Hippocrates time • The theological basis of bloodletting is Four Humors Theory, it was said to cure inflammation, infection strokes, manic psychosis and more Ancient Greek painting in a vase, showing a physician (iatros) bleeding a patient

Three Breakthroughs in Modern Surgery Pain, infection, bleeding were the three major problems to prevent surgery from progressing into modern science. The development of modern surgery has been benefited from three inventions: • Anesthesia麻醉术 • antisepsis and disinfection防腐消毒术 • transfusion输血术
Invention of anesthesia • Before invention of anesthesia the most commonly used analgesic agents were: marijuana, opium, stramonium, belladonna, alcohol or hypnogenesis. • The effects were rather poor, which cumber the number of elective surgical procedures
Invention of anesthesia 1772, British chemist Joseph Priesley seprated nitrous oxide (N2O), because it can relax diaphragm muscle and make people laughing so called laughing gas 1800,Humphry Davy found the analgesic effect of nitrous oxide
Invention of anesthesia Due to the euphoric effects of inhaling it, a property that has led to its recreational use as an inhalant drug As dancing outreach (ecstasy) today
Invention of anesthesia • March 30,1842a country doctor Crawford Long(1815-1878)successfully remove a neck tumor with ether anesthesia for a child, but the results not published • His Alma Mater Johns Hopkins University recognized him as the first one using ether as anesthetic agent • National Doctor’s Day – March 30 in USA (since 1993)
Invention of anesthesia • December1844 a American dentist Horace Wells(1815-1848) successfully extracted his own cheek teeth with inhaled N2O • But he failed in demonstration in Harvard Medical School Hospital February 1844 • 1864, American Association of Dentists gave the credit of invention of anesthesia to him.
Invention of anesthesia • October 16,1846, Wells’ assistant William Morton (1819-1868) during a public demonstration in MGH let a patient to inhale ether, and the famous surgeon Warrendissected a mandible tumor from the unconscious patient. • Morton was recognized the inventor of surgical anesthesia
麻醉术的发明 Obstetrician James Simpson(1811-1870)applied Chloroform instead ether as anesthetic agent,the Queen Victoria inhaled chloroform during the child birth.
Invention of anesthesia • “Inventor and Revealer of Inhalation Anesthesia: Before Whom, in All Time, Surgery was Agony; By Whom, Pain in Surgery was Averted and Annulled; Since Whom, Science has Control of Pain.“ (to William Morton) • Who was the first one to use anesthesia has always been a big debate • 1868, in Boston a monument was erected to commemorate the first operation under anesthesia in 1846, in which engraved: “To Ether or Either”
Invention of Surgical Antisepsis • Semmelweis a Hungarian obstetrician investigated the cause of high incidence of puerperal fever (childbed fever) in Vienna General Hospital and advocated hand wash with chloride of lime solution leading to the maternal death rate dropping from 18% to 1%. Ignac Semmelweis 1818-1865
Invention of Surgical Antisepsis • Semmelweis was attacked by his conserved colleagues and incurred persecution. • Ironically he died at 47 in an asylum from septicemia, but was honored as the “savior of mothers” after his death IQ Vs EQ Your character is your destiny
Invention of Surgical Antisepsis • In middle of 19th century the sepsis caused by operation was most popular with a mortality rate of 50% • Inspired by Pasteur’s discovery Joseph Lister created using carbolic acid in surgical antisepsis,with this method he saved a 11-year boy’s life who suffered a open complicated fracture in 1865 • The fetal rate for amputation,before antisepsis invention:16/35(45.7%),after 6/40(15.0%) Joseph Lister 1827-1912
外科防腐消毒法 • Lister’s antisepsis method was ignored in Britain and US • 1870, German adapted his method in Prussian-French warand saved many soldiers’ life. • 1877, Lister took the position of Department Head of Surgery in King’s College,and made his name in surgical circle and his surgical antisepsis was popularized • 1895-1900Lister was appointed as the Chairman of British Royal Society. Your character is your destiny
Progress of Surgical Techniques • 1877 German doctor von Bergmann sterilized the surgical instrument and dressing with high-temperature vapor • 1885German surgeon Neuber: surgical gown • 1889 American surgeon Halsted: rubber gloves,Austrian surgeon Mikulicz-Radecki: surgical mask • 1890,Halstedproposed the basic principles of surgery,laid the foundation of modern surgery

Invention of Blood transfusion • Blood loss is a threat for patient’s life, to control blood loss: cauterization, ligature, and blood replace • 1665, British physician Richard Lower first tried transfuse blood from sheep to a psychiatric patient • Transfusion was soon banned because of death caused by transfusing animal blood
Invention of Blood transfusion • 1818, Britishobstetrician Blundellfirst transfused blood to a postpartum bleeding woman from her husband • Afterwards he tried 10 times and 5 was successful
Invention of Blood transfusion • 1875,Landoisfound the cause of transfusion reaction- agglutination of red cells • 1900, Austrian scientist Landsteiner discovered agglutination was caused by immune reaction,and proposed the ABO blood types • 1939-41 Rh type was found (Rhesus monkey ) Karl Landsteiner 1868-1943
