In the United States, blood transfusions were performed nearly 3 million times during hospitalizations in 2011, making it the most common procedure performed. The rate of hospitalizations with a blood transfusion nearly doubled from 1997, from a rate of 40 stays to 95 stays per 10,000 population.
Patient Blood Management (PBM) [1] [2] [3] is a set of medical practices designed to optimise the care of patients who might need a blood transfusion. Patient blood management programs use an organized framework to improve blood health, thus increasing patient safety and quality of life, reducing costs, and improving clinical outcomes.
Under these conditions, to achieve the maximum benefit from the technique if ANH is used, no homologous blood will be required to maintain the H m if blood loss does not exceed 2940 ml. In such a case, ANH can save a maximum of 1.1 packed red blood cell unit equivalent, and homologous blood transfusion is necessary to maintain H m , even if ANH ...
This review also found no difference in the number of people who had clinically significant bleeding between platelet transfusions that contained a small number of platelets and those that contained a large number of platelets (high dose – 4.4 x 10 11 /m 2). [21] One of the review's included studies reported on transfusion reactions.
Red blood cell concentrates, also known as red cell concentrates or packed red blood cells, are red blood cells that have been separated for blood transfusion. [1] A red blood cell concentrate typically has a haematocrit of 0.50 – 0.70 L/L and a volume between 250 and 320 mL.
In 1628, English physician William Harvey discovered that blood circulates around the body. Soon thereafter, the first blood transfusion was attempted. In 1665 another English doctor Richard Lower successfully used blood transfusion between dogs to keep them alive. [1] Karl Landsteiner is recognized as the father of transfusion medicine.
Most blood transfusions involve adding blood or blood products without removing any blood, these are also known as simple transfusions or top-up transfusions. [ 3 ] [ 4 ] Exchange transfusion is used in the treatment of a number of diseases , including sickle-cell disease and hemolytic disease of the newborn .
For direct transfusions a vein can be used but the blood may be taken from an artery instead. [64] In this case, the blood is not stored, but is pumped directly from the donor into the recipient. This was an early method for blood transfusion and is rarely used in modern practice. [65]
