Western Front - Development of Surgical Methods and Medical Innovation
Descrição
The development of new types of weapons in World War One caused death and injury on a scale never seen before; new methods of treating soldiers that were wounded and injured were needed. Including: plastic surgery, brain surgery, blood transfusions and portable x-rays.
The development of new types of weapons in World War One caused death and injury on a scale never seen before; new methods of treating soldiers that were wounded and injured were needed.
Vaccination:
Many soldiers in the trenches died from tetanus and typhus
In the first year of the war, tetanus was the cause of 32 deaths per 1000 deaths on the Western Front
The development of vaccinations in 1915 against typhus and tetanus reduced the death rate to 2 per 1,000 deaths
Amputations and artificial limbs:
Many soldiers had limbs amputated to stop the spread of gangrene
The war years saw advances in the development of artificial limbs and moving joints
Plastic surgery:
This was a great advance for soldiers who suffered serious wounds from bullets and shell damage, especially to the face
End of 1915 - seven hospitals in France had specialist areas for coping with wounds requiring plastic surgery
One key figure was Harold Gillies, a British army surgeon, who developed a specialist department in Kent to treat facial injuries
This department opened in 1917, providing 1,000 beds and treating over 2,000 soldiers injured in the Battle of the Somme
Medical professionals discovered how to graft skin also
Brain surgery:
Huge numbers of head and brain injuries required surgeons to develop surgical methods, especially brain surgery
Two developments helped this process:
The ability to undertake blood transfusions
Use of X-rays to locate metal fragments inside the head
Harvey Cushing, an American surgeon, invented a magnet to extract bullets from head wounds
The Thomas Splint:
In the first few years of war, 80% of soldiers who had their femur broken by gunfire died from the injury
Medical officers only had simple splints which did not stop the broken bones from moving, causing blood loss and infection
In 1916, an invention by Welsh surgeon, Hugh Owen Thomas, caused the death rate to reduce from 80% to 20%
This invention was the 'Thomas splint'
It stabilised the fracture, putting the leg lengthways to prevent the bones from grinding against each other
This reduced blood loss and infection and decreased the number of amputations required
Robert Jones, Thomas' nephew, who worked as the British Army's Director of Military Orthopaedics in 1916, made sure the 'Thomas splint' was available for use at the front

Treating Wounds and Injuries
Development of aseptic surgery:
One of the biggest causes of death was infection
In the late-19th century, surgeon Joseph Lister pioneered aseptic surgery (performing surgery under sterile conditions reduced the onset of infection post-operation)
On the battlefield, less hygienic conditions meant it was difficult to prevent infection of a wound
It was through a trial and error process that surgeons attempted to overcome difficulties of infection
Use of chemicals such as carbolic acid and hydrogen peroxide to kill bacteria already in wounds
Surgeons discovered cutting away infected tissue and soaking a wound in saline solution reduced infection rates
It was only really by World War Two and after the discovery of penicillin that infection was properly addressed
Slide 5
Treating Wounds and Injuries
Blood transfusion:
Blood transfusions had been tried since the time of William Harvey, but most patients died shortly afterwards
Major advance in 1900, when Karl Landsteiner discovered blood could be divided into four types and each patient needed blood from someone of the same type
This advance meant that many soldiers were saved on the Western Front
However, the problem remained that it was not possible to store blood because it clotted so quickly
Blood transfusion:
A solution to the blood clotting problem came through a number of discoveries:
1914 - American scientist, Richard Lewisohn, discovered sodium citrate could be added to blood to prevent it from clotting
O. H. Robertson used this method to keep blood fresh during the war
Scientists discovered keeping blood refrigerated allowed it to be stored for longer periods
1917 - British surgeon, Geoffrey Keynes developed a portable machine that could store blood to enable transfusions
Portable X-rays:
Discovered by William Rontgen in 1895 and became significant during the First World War
X-rays saved lives by allowing surgeons to easily locate bullets, shrapnel and fragments of metal in a wounded soldier
This reduced infection which was a common cause of death
The problem in 1914 was that there was very few X-ray machines portable enough to be used on the front
Marie Curie, a pioneer in radiography, at the start of the war concentrated on developing a portable X-ray machine
October 1914 - 20 radiology vehicles constructed carrying X-ray machines were available on the front line
By 1916 X-ray machines became the standard across casualty clearing stations
