Immunohematology
Deals with the preparation of blood and blood components for transfusion, which includes the selection of appropriate and compatible components for transfusion. Each of the blood components have different indications depending on the patient's needs
Packed red blood cells, Fresh frozen plasma, Platelet concentrate, Cryoprecipitate
Examples of blood components
Blood banking
Immunohematology is commonly known as?
Transfusion medicine
This term replaced "Blood banking"
Transfusion medicine
Stresses on patient care and the increasing role of the evaluation of clinical results
Transfusion medicine
Concerned with the proper selection and utilization of blood components, as well as the removal of blood and blood components in the treatment or prevention of disease
Transfusion medicine
When indicating for transfusion therapy, the physician has to weigh the expected benefits vs the potential dangers.
To restore or maintain oxygen carrying capacity, blood volume, hemostasis, and leukocyte function
Expected benefits of Transfusion medicine
To restore or maintain oxygen carrying capacity
Expected benefit of Transfusion medicine such as in the case of anemic hypoxia where the oxygen carrying ability of the blood is decreased
To restore or maintain blood volume
Expected benefit of Transfusion medicine such as when the patient underwent major surgery or had a serious injury and lost blood has to be replaced
To restore or maintain hemostasis
Expected benefit of Transfusion medicine such as in the case of dengue hemorrhagic fever where there is thrombocytopenia and so platelet concentrate needs to be transfused to the patient
To restore or maintain leukocyte function
Expected benefit of Transfusion medicine such as in the case of patients with lifethreatening bacterial and fungal infections, and have low WBC counts. (To augment their WBC levels, leukocyte concentrates may be transfused)

Development of the method of anticoagulant and preservation of blood for transfusion
What major factor that greatly influenced the field of transfusion medicine transformed the transfusion procedure, from one that had to be performed with both donor and recipient in the same place at the same time, to basically the blood banking system in use today?
Pope Innocent VII
The first blood transfusion recorded in history was done on this person who had an apoplectic stroke, became weak, and went into a coma.
Blood was extracted from 3 young boys and was transfused to the pope, hoping that the boys' blood could cure him. Unfortunately, all four of them died
William Harvey
His description of the circulation of blood first kindled the interest in blood transfusion
William Harvey
He showed that the heart was a pump and that the pulse wave was caused by the contraction of the heart which expel blood into the arteries. The same blood return to the heart by travelling through the veins.
William Harvey
He deduced that the function of the valves was to prevent backflow of blood in the veins
Richard Lower
He experimented on animal-to-animal transfusion
Richard Lower
He began his experiments on animal to animal transfusion (Dog to dog blood transfusion). He joined the jugular veins of 2 dogs, but the blood clotted in the tubing since there was no anticoagulant.
It is most likely that the first public demonstration of transfusion was done by him. Although unsuccessful, his efforts provided the stimulus for series of experiments on animals, and eventually lead to animal to man transfusion
Jean-Baptiste Denis
He was the first to perform animal to man transfusion
Jean-Baptiste Denis
He transfused calf blood to a man who manifested insanity. Although the first transfusion had no adverse reactions, a second transfusion on the man resulted in a hemolytic transfusion reaction.
Several months later, the man died. The widow accused Denis and his assistant of causing the death
Hemolytic transfusion reaction
Jean-Baptiste Denis's second transfusion on the man (calf blood to man transfusion) resulted in this condition
Jean-Baptiste Denis
He is the reason why the faculty of medicine in Paris issued a decree which stated that the procedure of transfusion was a criminal act unless given sanction by the faculty of medicine

James Blundell
He assisted Samuel Armstrong Lane in performing the first successful whole blood transfusion to treat a blood condition
Hemophilia
What blood condition were Samuel Armstrong Lane and James Blundell trying to treat with their whole blood transfusion?
Factor VIII
What clotting factor is missing in hemophilia A?
(Genetic disorder where blood does not clot properly due to lacking clotting factors, leading to excessive bleeding and hemorrhages and is fatal in some cases.)
Factor IX
What clotting factor is missing in hemophilia B?
(Genetic disorder where blood does not clot properly due to lacking clotting factors, leading to excessive bleeding and hemorrhages and is fatal in some cases.)

He recommended sodium phosphate and this was perhaps the first example of blood preservation research. However, his attempts using sodium phosphate were unsuccessful.
Clotting
This was the principal obstacle for Joseph Braxton Hicks to overcome in blood transfusion
Sodium phosphate
The non-toxic anticoagulant Joseph Braxton Hicks experimented with using chemical methods to prevent the coagulation of blood at St. Mary's Hospital in London.
Transfusion of Milk from Cows/Goats to Man
In 1873-1880, physicians in the United States were documented to have transfused milk from cows/goats to humans.

Francis Peyton Rous, J.R. Turner
They introduced citrate dextrose solution for the preservation of blood.
Francis Peyton Rous, J.R. Turner
After the development of devices used for transfusion, research on the different anticoagulants, then the development of preservative solutions to enhance the metabolism of RBCs followed. Glucose was tried as early as 1916.
Following World War I, these two men introduced the citrate dextrose solution for the preservation of blood. This aided in the transition from vein to vein method to direct transfusion.
Oswald Robertson
He is credited as the Creator of "Blood Depots"
Blood depots
The medical corps would look for volunteers, these were usually lightly wounded soldiers, with a Type O blood. Each soldier would then donate about 2 cups of blood, which would be put in a bottle and treated with sodium citrate. The bottles would be stockpiled near the fighting in ammunition boxes packed with saw dust and ice, which help them keep for a few weeks. The result is the first ___, the precursor of modern Blood Bank. Transfusion kits were soon taken into the field allowing medics to give blood quickly to soldiers in shock.

This was used to separate the whole blood into different blood components.
1
After centrifugation, each blood component is used for a different indication thus the component separation maximized the utility of how many whole blood units?
Refrigerated centrifuge
It is refrigerated since the low temperature storage slows down the glycolytic activity and allows the shelf life of the component to be extended.

Blood component therapy
Therapy that solved the problems of frequent transfusions such as circulatory overload
Blood component therapy
is the therapeutic use of specific components of blood instead of whole blood so that 1 patient can benefit from 1 donated blood unit at the same time avoiding TACO.
