A

It created a sleep like state with none of the side effects of ether

12
Q

3) Easier to unconscious than awake
4) Behaviour; un-womanly/manly behaviour
5) Infection (black period of surgery)
6) Religious reasons
7) Dosages - hard to get right
8) Speed - loss of skill

16
Q

Why did the Church oppose Chloroform/anesthetics (2) ?

A

2) Chloroform was a new development and people were wary.
3) Felt it was easier to die unconscious than awake and struggling.
4) Couldn’t explain rise in the infection and death rate (black period of surgery) and were put off. (Hannah Greener)

19
Q

When and what was the black period of surgery

A

1847 to 1877. Whilst patients were unconscious surgeons could try out more complicated operations, this lead to more people getting infections, losing blood and dying.

20

1) Natural suspicion
2) Victorian Britain was very religious

Give 3 reasons why Simpson didn’t help solve the problem of pain relief…

A

1) Snow made Chloroform safe and usable (inhaler) Simpson’s chloroform had fatal side effects
2) Without Queen Victoria’s endorsement it would’ve been forgotten; opposition to chloroform meant it wasn’t used
3) Simpson wasn’t the first to develop pain relief (N.O and Ether)

26
Q

What did the invention of anaesthetics allow

A

Unconscious patients allowed more complex surgeries to be developed and refined (could remove tumours and gallstones)

27
