Blood Transfusions in WW1

Blood transfusion WW1

method of replacing lost blood in injured soldiers

Early problem

blood quickly clotted making transfusions difficult

Clotting issue

blood would thicken and block flow between donor and patient

Anticoagulant discovery

sodium citrate used to stop blood clotting

Sodium citrate

chemical that prevents blood from clotting during storage

Richard Lewisohn

helped introduce safe anticoagulant use in transfusions

Blood storage improvement

allowed blood to be kept for short periods before use

Direct transfusion method

blood passed directly from donor to patient

Indirect transfusion method

blood stored and then given to patient later

Donor requirement

healthy soldiers or volunteers needed to donate blood

Blood typing discovery

helped match donor and patient blood groups

ABO blood groups

classification system for human blood compatibility

Importance of matching blood

prevents clumping and death during transfusion

Karl Landsteiner

discovered blood groups and improved transfusion safety

Blood banks WW1

not fully developed but early systems began to form

Geoffrey Keynes

developed portable blood transfusion equipment

Portable transfusion kits

allowed blood to be used closer to battlefield

Franz Grobbel

developed early blood transfusion techniques in Germany

Shock treatment WW1

transfusions helped treat blood loss from injuries

Haemorrhage

severe blood loss from wounds

Effect of blood transfusion

increased survival rates of injured soldiers

Battlefield injuries

shrapnel and bullets caused major blood loss

Timing of transfusion

early transfusion improved chances of survival

Transport of blood

had to be carefully handled to avoid contamination

Sterilisation importance

equipment had to be clean to prevent infection

WW1 medical advancement

transfusion became more reliable over time

Medical limitation WW1

lack of refrigeration made storage difficult

Use in hospitals

transfusions often done in casualty clearing stations

Emergency transfusion

used for severely wounded soldiers in shock

Blood donor pools

soldiers from same regiment often used as donors

Effect on surgery

allowed more complex operations due to blood replacement

Medical innovation WW1

war accelerated development of transfusion techniques

Survival rate impact

more soldiers survived severe injuries than in earlier wars

Key problem solved

blood loss was one of the main causes of death in WW1
