Medicine Flashcards
Why were strong stubborn theories a barrier to progress in Britain?
Some people thought that the outbreak if disease was a divine punishment for sinful living.
Others believed in the theory of the four humours, which was an ancient concept.
They also believed in miasma, which was drifting clouds in air that carried rotting matter, in the form of a bad smell.
What was the theory of four humours?
Blood, phlegm, yellow bile and black bile, They thought that disease was caused by an imbalance in the humours, and could only be restored by restoring balance.
Why were these theories widespread and deeply held?
People did not devote time and thought to studying. They thought that they already knew what was causing disease.
Training and treatment of doctors based on these theories of causation, so discouraged young doctors from questions flaws/assumptions, which led to little progress
Existing attitudes were a barrier.
Why was there a lack of progress in identifying and developing cures?
Lack of funding - no consensus that government should fund research in 1848
Lack of development in technology- no macroscopic by 1848
Ignorance of human body - small number of dissections, but religion objected to performing dissections.
Who is Florence Nightingale and her significance (at Scutari)?
Florence nightingale was a nurse during the Crimean War (1853-6)
Because of a scandal concerning high death rate in Scutari, she was asked to take a team of handpicked nurses to improve matters.
When was the Crimean war?
1853-56
Conditions of medical wards in Scutari before Nightingale?
Soldier died due to infection in unsustained numbers rather than due to the severity of wounds.
Disease spread easily in wards
How did the death rate change in Scutari due to Nightingale?
After nightingale, death rate fell from 40% to 2%
What were Nightingale‘s innovations?
Hygiene, Ventilation, food and organization
Systematic and regular cleaning of hospital wards and equipment
Frequent cleaning of wounds and changing dressings.
Regular washing of patients and changing of dressing.
Ventilation of wards allowed fresh air to enter and circulate/
Insistence on restructuring the layout of hospitals, with space between beds.
Sub-division of hospitals into different wards
Establishment of kitchen to provide fresh food
Rating of money to ensure fresh medical supplies sent from Britatin
Why is it important not to mythologize Florence Nightingale?
She believed in miasma
She did not realise that the hospital was built on a cesspool (affected water supply and air quality)
In 1855, gov sanitary commission improved drains and water supply (could be argued that it helped with the death rate)
What were the 3 main problems in surgery by 1848?
Pain - alcohol was used as a painkiller, or patients were knocked unconscious
Infection- Ignorance of causes of infections, so doctors did not clean hands sterilise equipment or change clothes. This meant operations were very unhygienic, and most people were more likely to die due to infection.
Bleeding - The surgeons can not see what they are doing.
Blood loss - by 1848, methods for restriction were harmful, tourniquets clamps caused nerve damage when left too long (cauterization) and ligatures led to infection if applied with dirty hands.
Who was James Simpson and what did he discover?
He discovered Ether as an effective anaesthetic had had problems with dosage and side effects so discovered chloroform and chloroform mask.
What is chloroform and how was it democratised?
An anaesthetic and was democratised when Queen Elizabeth used it for childbirth and recommended it public good example of how persistence of individual and prestige of another individual can result in lasting change.
What were the problems with anaesthesia?
Dosage - before chloroform mask had been invented safe dosages could not be determined as it depended on factors.
Confidence of doctors - death rate increased as a result of anaesthesia. Doctors could perform more evasive and complex surgeries which were fatal, as blood loss and infection had not been solved.
What were the problems with public health in 1848?
Rapid industrialisation had led to overcrowding in cities as people left countryside for work in cities.
Poor quality of housing and poor sanitation in cities as toilet facilities were basic and sewers ran into rivers.
What were the consequences of the problems in public health in 1848?
Promoted spread of disease, high death rate, short life expectancy among industrial workers.
Who was Edwin Chadwick and what did he do?
Tasked by government to produce report on sanitary conditions.
His report in 1842 recommended local authorises provide clean water, build proper drains and sewers, and collect rubbish from houses and streets. He achieved limited success because he was stubborn and arrogant.
What really lead to the Public Health Act 1848, and what did it do?
The cholera outbreaks due to poor hygiene and unsanitary conditions, would have even middle and upper class people dying.
It could no longer be ignored, so an Act of a Board of Health was created and towns collected rubbish and built sewer systems.
How significant was the Public Health Act in 1848?
Local authorities were only permitted to make improvement if they wished to they were not forced. This is because actions required money which required local taxes, so some authorities were unwilling to pay; there was no link between hygiene and disease.
The board of health was not permanent and lasted 5 years, Chadwick was forced out in 1854
Why was cholera a major threat?
The persistence of outbreaks (1842, 1848) which killed 50,000 people.
Cholera was a major killer with typhus, but it was most feared because prevention did not work (miasma)
What was the significance of John Snows work on cholera?
Snow hypothesised that cholera was caused by food or liquid taken orally and tested this theory.
He was right but his finding did not lead to rapid change, because people did not believe that dirty water caused cholera (miasma beliefs)
It showed that to break a harmful change of continuity and caused lasting change an important individual had to make a related breakthrough.
What leads to Snows work gaining greater acceptance?
Pasteur‘s germ theory proved water carried disease.
What factors contributed to Pasteur‘s germ theory?
Advancement in technology; powerful microscopes
Role of individuals and funding
When and what was Pasteur‘s germ theory?
1861 theory proposed that germs caused disease.
1878, book published on germ theory with specific application to medicine.
