Blood transfusions and safety procedures

In England, experiments on the transfusion of blood were pioneered in dogs in by physician Richard Lower. In November Lower transfused the blood of a lamb into a man.

Blood transfusions and safety procedures

Safe transfusion – right blood, right patient, right time and right place

The most common adverse reactions from blood transfusions are allergic and febrile fever—associated reactions, which make up over half of all adverse reactions reported.

Rare but serious adverse reactions include infection caused by bacterial contamination of blood products and immune reactions due to problems in blood type matching between donor and recipient.

These adverse reactions are not common following blood transfusions but are tracked so that CDC can better understand them and develop interventions to prevent them.

Blood transfusions and safety procedures

Allergic reaction An allergic reaction results from an interaction of an allergen in the transfused blood with preformed antibodies in the person receiving the blood transfusion.

In some instances, infusion of antibodies from the donor may be involved. Acute hemolytic transfusion reaction AHTR An acute hemolytic transfusion reaction is the rapid destruction of red blood cells that occurs during, immediately after, or within 24 hours of a transfusion when a patient is given an incompatible blood type.

Delayed hemolytic transfusion reaction DHTR A delayed hemolytic transfusion reaction occurs when the recipient develops antibodies to red blood cell antigen s between 24 hours and 28 days after a transfusion. Symptoms are usually milder than in acute hemolytic transfusion reactions and may even be absent.

DHTR is diagnosed with laboratory testing. Delayed serologic transfusion reaction DSTR A delayed serologic transfusion reaction occurs when a recipient develops new antibodies against red blood cells between 24 hours and 28 days after a transfusion without clinical symptoms or laboratory evidence of hemolysis.

Clinical symptoms are rarely associated with DSTR Febrile non-hemolytic transfusion reaction FNHTR Febrile non-hemolytic transfusion reactions are the most common reaction reported after a transfusion.

These reactions are generally mild and respond quickly to treatment. Fever can be a symptom of a more severe reaction with more serious causes, and should be fully investigated. Hypotensive transfusion reaction A hypotensive transfusion reaction is a drop in systolic blood pressure occurring soon after a transfusion begins that responds quickly to cessation of the transfusion and supportive treatment.

Hypotension also can be a symptom of a more severe reaction and should be fully investigated. PTP usually occurs days after a transfusion and is more common in women than in men.

Transfusion-associated circulatory overload TACO Transfusion-associated circulatory overload occurs when the volume of blood or blood components are transfused cannot be effectively processed by the recipient. Symptoms may include difficulty breathing, cough, and fluid in the lungs.

Transfusion-related acute lung injury TRALI Transfusion-related acute lung injury is a serious but rare reaction that occurs when fluid builds up in the lungs, but is not related to excessive volume of blood or blood products transfused.

Symptoms include acute respiratory distress with no other explanation for lung injury such as pneumonia or trauma occurring within 6 hours of transfusion. The mechanism of TRALI is not well understood, but is thought to be associated with the presence of antibodies in donor blood.

Symptoms include fever, a characteristic rash, enlargement of the liver, and diarrhea that occur between 2 days and 6 weeks post transfusion.

Though very rare, this inflammatory response is difficult to treat and often results in death. Transfusion-transmitted infection TTI A transfusion-transmitted infection occurs when a bacterium, parasite, virus, or other potential pathogen is transmitted in donated blood to the transfusion recipient.

Top of Page References.A blood transfusion is a safe and relatively simple medical In most cases, the blood comes from volunteer donors. The blood of the donor, which is carefully screened to ensure its safety, must match the blood of the person receiving it.

But it helps to know that in most cases, blood transfusions are common procedures and complications.

A blood transfusion is a way of adding blood to your body after an illness or injury. If your body is missing one or more of the components that make up healthy blood, a transfusion can help.

A blood transfusion is a safe, common procedure in which blood is given to you through an intravenous (IV) line in one of your blood vessels. Blood transfusions are done to replace blood lost during surgery or due to a serious injury. The root cause of most incidents is misidentification at the time of pre-transfusion blood sampling, laboratory testing, collecting the blood component from the blood bank or administration of the transfusion at the bedside.
