However, this problem was
solved by 1900.…read more

The first anaesthetics
Nitrous oxide (or laughing gas) discoveries to have anaesthetic
properties by Sir Humphrey Davy in 1799. some surgeons had
some success with it and it reduced pain but did not knock them
out, meaning that its impact was limited.
In 1846, American surgeon named John Collins Warren used
ether as an anaesthetic. It was bit better than laughing gas as
made patient unconscious ­ famous British surgeon and
showman Robert Liston used ether as amputation in 1847.
However, ether was an irritant that caused coughing and
sickness and also very liable to catch fire…read more

in 1853
· John Snow invented a special inhaler to regulate doses, which

public accept chloroform more willingly.

Dealing with infection
Following the development of
anaesthetics, deaths from surgery
increased. This was because surgeons
did more and more complex operations
but had not solved the problem of
infection. In the 1980's surgeons still had
very little understanding of how germs
spread and what causes gangrene and BREAKTHROUGH
sepsis ­ both big killers of surgical
patients. NUMBER 2
Even after the germ theory was
published in 1861 it took 6 years to apply
it to surgery and the treatment of
patients. It was Joseph Lister who made
the breakthrough and developed the first
effective antiseptics and helped solve
the problem of infection…read more
