X-rays and the development of blood transfusions
X-rays
Their development was accidental
Discovered by
Wilhelm Roentgen
in
1895
Radiology departments opened as soon as
1896
in some British hospitals
Dr John Hall-Edwards
was one of the first doctors to make a diagnosis based on information from an x-ray
Early problems
The health risks associated with x-rays were not fully understood
The amount of radiation in early x-rays is 1500 times the amount that is emmited in their modern counterparts
Exposure to x-rays could cause hair loss and burns
Early x-rays took a very long time
Larger x-ray machines were difficult to move around
Blood transfusions
James Blundell
started experiments with blood transfusion in
1818
to help women who lost blood during birth
Between
1818-1829
, he carried out ten transfusions, up to half of which were successful
At the time, blood transfusions were carried out with the donor directly connected to the reciver
Problems
Blood clots clogged the tubes that transferred the blood
High rejection rates of the blood due to incompatible donors
There was a danger of infection from unsterilized equipment
