Q

problems with chloroform

A
  • it was hard to gain an exact does and it could be dangerous/lethal - the healthier the more likely you were to die because you inhaled more in - Hannah Greener died from an overdose in 1848 during an operation to remove her toenail

Q

how anaesthetics made a contribution

A
  • surgeons could do longer operation - 1850 - Queen Victoria successfully gave birth using chloroform which changed attitudes towards painkillers

Q

how anaesthetics did not make a contribution

A
  • army surgeons in the Crimean War (1853-56) thought that soldiers should put up with the pain - anaesthetics did not battle infections so death rates were still high - religious oppositions was that childbirth pain was a punishment from God - patients died from incorrect dosage

Q

why did surgeons stop using chloroform/painkillers

A
  • having no pain allowed for longer operations = more exposure to unclean environment = patients often got infections that would later kill them - death rates rose - surgeons stopped using painkillers in 1870s

Q

germ theory proof/experiment

A

Q

why did the swan neck flask work

A

the curve in the neck allowed for air to reach the juice but didn’t allow any dust particles through thus stopping bacterial growth

Q

development of pasteurisation

A

spoiled wine contained microbes so pasteur tired killing microbes with heat - high temperature = bad taste -low temperature = not all the microbes killed

pasteur on silk worms

A

1865 - asked to investigate disease affecting silkworms (that was causing problems in the economy) - he worked out that the infection was transmitted by parasites and showed how infected worms could be isolated and destroyed

Q

pasteur’s main problems

A

Pasteur was convinced that microbes caused disease in humans, but he was never able to directly link one microbe with a disease. People could have doubts because of this.

Q

what happened in 1868 (koch)?

A

French doctor showed animals injected with anthrax infected blood caught the disease - koch continued this work - koch found the anthrax microbe produced spores that lived after the animals death - proved spores could develop into the germs and infect

41
Q

Paul Ehrlich - background

A
  • introduced into cellular staining by family - continued work on cellular staining He reasoned that chemical agents could be used to heal diseased cells or to destroy infectious agents
42
Q

Paul Ehrlich discoveries

A
  • a new way to stain the tuberculosis bacterium - differentiated between different types of blood cells of the body - discovered uses of methylene blue in nervous conditions and for dyes
43
Q

Paul Ehrlich and syphilis

A

1909- Salvarsan 606 helped treat syphilis and became known as the magic bullet.

44
Q

magic bullet

A

Salvarsan 606 only targeted the infected cells

45
Q

what happened during the cattle plague?

A

1866 - many still believed in spontaneous generation - farmers were reluctant to kill infected cows - disease spread very quickly

46
Q

solution to the cattle plague

A
  • government appointed Lionel Beale to investigate - only quarantining seemed to work but lead to food shortages - found that a specific microbe was responsible
47
Q

effects of the cattle plague

A

-showed that the microscope could be useful to everyday life - the germ theory was correct

48
Q

charles bastion

A
  • professor of anatomy - high level individual - 1860s wrote articles that argued for spontaneous generation theory
49
Q

john tyndall

A
  • highlighted bastion’s errors - lectured on dust and disease and about koch - demonstrated the existence of tiny microbes in the air
50
Q

contagionists - causes of disease

A

infection was spread by contact with infected individual or bacteria

51
Q

contagionists - solutions

A
  • epidemics controlled by quarantine or preventing contact - they could not explain why some people did not always get the disease despite contact
52
Q

anti-contagionsist - cause of disease

A
  • diseases like cholera, plague and typhoid were caused when infections interacted with the environment - linked with the miasma theory
53
Q

anti-contagionsists - solutions

A
  • epidemics controlled by cleaning up the environment - couldnnt explain why it worked
54
Q

typhoid fever - effects

A
  • changed many ideas on spontaneous generation - germ theory became widely accepted - government attitude started to change
55
Q

Cheyne and Robert koch

A

1879 - translated koch’s work and wrote about his findings - having many others support and spread koch and pasteur’s theories persuaded many

56
Q

william dallinger and john drysdale

A

1874 - microscope research into life cycle of germs

57
Q

Franco-prussian war

A

1870-71 - created a large rivalry between koch and pasteur which pushed them to discovery

58
Q

ignas semmelweiss

A

in 1847 used antiseptics to lower death rate from 35% to 1% but few followed suit

59
Q

Joseph lister - carbolyic acid

A

recommended the use of carbolic acid for surgery as an antiseptic: room sterilised, surgical equipment sterilised and the wound also wrapped in carbolic acid soaked dressings

60
Q

Joseph lister - numbers

A

rate or infection dropped from 50% to 15% in 4 years

61
Q

joseph lister’s invention

A

1871 - machine that sprayed carbolic acid around the room and patient during surgery

62
Q

joseph lister’s invention negatives

A
  • carbolic acid dried skin and irritated lungs - took a long time to prepare
63
Q

joseph lister downfalls

A
  • still operated in usual clothes - still believed microbes were simple only one type
64
Q

reasons for opposition to joseph lister

A
  • jelousy - opposed to change - inaccuracies could cause increased mortality rates - british military surgeon said it was good to hear the shout and brawl of patients, not die quietly
65
Q

charles chamberland

A

1881 - steam sterilizer for medical instruments

66
Q

gustav neuber

A
  • insisted on throughly scrubbing staff before entering - first sterile operating theatre - air was sterilized - published results in 1886
67
Q

berkeley moynihan

A
  • first british surgeon to use rubber gloves but he was ridiculed - facemasks. gloves, surgical gowns, smaller operating theatres reduced infections
68
Q

joseph lister’s success

A

1865 - mended a fractured boy’s leg and wrapped it in dressing soaked in carbolic acid, it did not get infected and he recovered (usually gets infected and leads to amputations)

69
Q

florence nightingale

A
  • during the Crimean War (1853-56) she took notice of the dirtiness and deterioration of the military hospitals so improved cleanliness and sanitation - she helped bring down the death rate from 40-2% - Nightingale fundamentally changed the role of nursing in hospitals - key figure in introducing new professional training standards -she published “notes on hospitals” in 1863 setting out her principals for running clean, safe and well-ventilated hospitals
70

typhoid (contaminated food and water) tuberculosis (passed by sneezing and coughing) cholera (contaminated water)

73
Q

main disease/injury for workers

A

coal miners - pneumoconosis (lung disease) factories making match heads - “phossy-jaw” (jaaw would be eaten away and could also include brain damage) this was due to the inhaled phosphorus fumes machines in factories didn’t have guards so often limbs got stuck and many people died or needed amputations

“do nothing” the attitude many people shared that the government should not be involved in public matters or health

80
Q
