Read p. 173-4 and find out the reasons why surgery has
improved in recent years. Complete a spider diagram
including the following categories:
Improved anaesthetics
Antibiotics
Teamwork
Resources
Keyhole surgery
Microsurgery
Improved anaesthetics

1930s Helmuth Wesse discovered a method of
injecting anaesthetics into blood stream –
allowing dosage to be controlled and operations
to last longer
Antibiotics


Discovery & mass production of penicillin
helped to increase success rate of operations
Led to developments in more complex surgical
techniques e.g. transplants and replacement
surgery
Penicillin tablets – extremely difficult to obtain
initially, but now a very common drug
Teamwork

Dr Christian Barnard (below) – doctor who
pioneered heart transplant surgery required
teams of doctors and who were expert in
different fields from anaesthetics to
cardiography
Resources


Complex operations very expensive – teams of
surgeons, expensive drugs, aftercare etc.
Government and media question how much
should be spent on healthcare and where
resources should be directed
Should the NHS pay for controversial operations like cosmetic surgery?
Keyhole surgery


Reduces size of wound created and reduces
chance of infection
Fibre-optics and computer-assisted surgery have
made this approach possible
Microsurgery

Ability to attach fine blood vessels and nerve
endings, e.g. severed limbs
This picture shows the limb of a
Taiwanese vet which was successfully
reattached following an incident at a zoo
in Taiwan in 2007
