Chapter 2 - The Beginnings Of Change Flashcards
What was the Renaissance
It was triggered by the rediscovery of a love of all things classical
Led to people challenging ideas and beliefs in science, technology and how the world was viewed
Led to many Eminent people to question the beliefs of Galen and other classical scholars
New inventions such as the microscope revolutionised the work of both scientists and physicians
Inventions of caxtons printing press enabled the more rapid spread of ideas across Britain
Who was Andreas Vesalius
1514-1564 challenged galens works on human anatomy and developed much more accurate views of the inside of the human body, by unlike Galen dissecting humans rather than animals
Carried out his own dissections
Believed anatomy was the key to understanding how human body worked
Published de humani corporis fabrica in 1543 which changed attitudes to medicine
Tell me about being ill in the seventeenth century
Biggest killer diseases in 17th century were fever, consumption, teeth, grilling in the guts and convulsions - not so different from 16 or 15tj century
Treatments not so very different than before
What changed during the Renaissance
Introduced idea of a more scientific method which was readily adopted by some people and scorned by others
Who was ambroise paré,
A French barber surgeon, became a surgeon in French army
He ran out of oil for cauterising wounds so made a mixture of egg yolk, turpentine and oil of roses to dress wounds - much less painful and much more effective at helping healing
Also used ligatures to tie off wounds after amputation instead of cauterisation - found wounds healed better
Later developed artificial limbs for those who had lost a hand or leg due to wounds
Time as an army surgeon allowed paré to observe his patients and treat them more effectively
Published experiences in a book “Les oeuvres in 1575” and became famous across Europe
Considered one of the fathers of modern surgery
What part did art play in improving people’s health during the Renaissance
Artists like Leonardo da Vinci went to great lengths to study the human body so they could better represent it in their drawings and paintings
Began to study corpses to help them accurately draw humans
Short step from dissecting parts of body’s to see how muscles and sinews worked
Artists also illustrated the medical books, helping to spread new knowledge and ideas
Tell me about the Renaissance and Galen
Many of galens works retranslated into Greek and Latin - compared and efforts made to get back to the original meaning
Galen regarded as the font of all medical knowledge
- but this didn’t last
More artists and surgeons studied anatomy and the more humans dissected they began to notice discrepancies between what Galen said and what they were discovering for themselves
Initial reaction was that Galen was right, and the current anatomists were wrong
Gradually enough opinions grew to successfully challenge Galen and cast doubts on his observations - once challenged on anatomy then other challenges followed
Medical world split in 2 - physicians who learned from texts such as Galen and surgeons who were exploring the human body on a daily basis and we’re learning by experiment
Scientific discovery played a part in this as new tools like the microscopes - so both scientists and medical men could look at things in ever more detail
Tell me about William Harvey
Most famous work was on the “on the motion of the heart” was published in 1628, challenged the work of Galen and the ancients
While studying In Padua, Harvey was taught that veins in the human body had valves and blood pumped only 1 way but no one knew how or why
Harvey experimented on animals and discovered blood was pumped around the body in a circular motion - lead to discovery of circulation of blood
Discovery made as a result of theoretical work as he was unable to see capillaries in bloodstream and made due to experiment and observation
Work on amphibians allowed him to see the blood circulating much more slowly
Showed in diagrams blood only flowed one way
Also able to show that galens belief that the liver not the heart was the centre of the human body was completely wrong
Galen believed liver made new blood to prescribe that lost around the body
But circulation of blood proved this wrong and also challenged bleeding as a cure - if Harvey was right then it was impossible for body to have To much blood
How was Harvey’s work reacted to
Those who supported Galen heavily rejected it
Argued Harvey couldnt see capillaries and therefore couldn’t prove their existence
Most we’re conservative and resistant to change - Harvey lost a lot of patients due to his crazy ideas
Who was Thomas Sydenham
Said to be English Hippocrates
Said best medical book was to read Don Quixote
Believed in close observations of symptoms of a disease and as little intervention as possible
carefully Monitor I symptoms and treatments given that way to build up a body of knowledge
B
Believe each disease had different characteristics
Developed a successful treatment to treat smallpox- used piled blankets on the patient and administered lots of hot drinks trying to sweat the disease out of body. Sydenham divised a cool ther lay prescribing lots of fluids, very moderate bleeding and keeping the patient as cool as possible - has echoes of 4 humours
What was the don Quixote
First published in 1605
Follows adventures of Don Quixote as he travels around the country, righting wrongs and having adventures
Regarded as one of the best novels in any country at the time and would have been well known by educated people in Britain
Tell me about John hunter
1728-93
Was a famous surgeon and anatomist and came to believe the best way to heal deep wounds was to leave as much as possible to nature
Served as a surgeon during the seven years war where he dealt with gunshot wounds and amputations
Edward Jenner was one of his students
He was known as the father of scientific surgery
Summarise the impact of the Renaissance in Britain
Initially Renaissance strengthened the ideas of Galen in the way disease should be treated
The Renaissance also brought about a more questioning approach to the work of Galen and Hippocrates
Harvey and Sydenham Made advances in the way people understood and treated diseases
Some people supported the new ideas while others opposed them, sticking closely to galens teaching
It’s difficult to decide to what extent these new ideas impacted on health and the people
Were people more likely to survive surgery then in medieval times than in early modern Britain
Ambrose paré improved surgery
Surgeons skilled improved too, still no reliable anaesthetics although wine and opium began to be. Used widely with unpredictable results - an incorrect dose could prove fatal
Tell me about Samuel Pepys
Gave an example of how ordinairy people viewed the prospect of an operation
On March 26 1658 he underwent an operation successful to remove s stone from his bladder
