Blood transfusions are a life-sustaining and life-saving treatment but they aren’t without risk. Conditions that warrant blood transfusions range from acute trauma to intraoperative blood loss to compromised blood-cell production secondary to disease or treatment. If you’re a nurse on the front line of patient care, you must be adept at administering blood products safely and managing adverse reactions with speed and confidence. Show Why reactions occurBlood transfusion reactions typically occur when the recipients immune system launches a response against blood cells or other components of the transfused product. These reactions may occur within the first few minutes of transfusion (classified as an acute reaction) or may develop hours to days later (delayed reaction). If red blood cells are destroyed, the reaction may be classified further as hemolytic all other types of reactions are broadly classified as nonhemolytic. Some reactions result from infectious, chemical, or physical forces or from human error during blood-product preparation or administration. (For details on types of reactions, signs and symptoms, appropriate interventions, and prevention methods, see A closer look at transfusion reactions by clicking on the PDF icon above) Before starting the transfusionSafe practice starts with accurate collection of pretransfusion blood samples for typing and crossmatching. Some facilities may require a second authorized staff member to witness and sign the form as the phlebotomist obtains the specimen. Also take these other key actions before you begin the transfusion:
PremedicationTo help prevent immunologic transfusion reactions, the physician may order such medications as acetaminophen and diphenhydramine before the transfusion begins to prevent fever and histamine release. Febrile nonhemolytic transfusion reactions seem to be linked to blood components, such as platelets or fresh frozen plasma, as opposed to packed red blood cells; thus, premedication may be indicated for patients who will receive these products. Such reactions may be mediated by donor leukocytes in the plasma, causing allosensitization to human leukocyte antigens. Cytokine generation and accumulation during blood component storage may play a contributing role. Leukocyte-reduced and irradiated blood productsUse of blood products that have been leukocyte-reduced, irradiated, or both has been shown to reduce complications stemming from an immunologic response. In organ transplant candidates, these products reduce the risk of graft rejection. Administering the transfusionMake sure you know the window of time during which the product must be transfused starting from when the product arrives from the blood bank to when the infusion must be completed. (See Quick guide to blood products by clicking on the PDF icon above). Failing to adhere to these time guidelines increases the risk of such complications as bacterial contamination. Detecting and managing transfusion reactionsDuring the transfusion, stay alert for signs and symptoms of a reaction, such as fever or chills, flank pain, vital sign changes, nausea, headache, urticaria, dyspnea, and broncho spasm. Optimal management of reactions begins with a standardized protocol for monitoring and documenting vital signs. As dictated by facility policy, obtain the patients vital signs before, during, and after the transfusion. If you suspect a transfusion reaction, take these immediate actions:
Also return the blood product to the blood bank and collect laboratory samples according to facility policy. If and when clinically necessary, resume the transfusion after obtaining a physician order. Carefully document transfusion-related events according to facility policy; be sure to include the patients vital signs, other assessment findings, and nursing interventions. Most fatal transfusion reactions result from human error. The most important step in preventing such error is to know and follow your facilities policies and procedures for administering blood products. Be aware, though, that prevention isn’t always possible which means you must be able to anticipate potential reactions and be prepared to manage them effectively. To promote good patient outcomes, you must be knowledgeable about the best practices described in this article. Selected references Silvergleid A. Immunologic blood transfusion reactions. UpToDate.

All health care practitioners who administer blood or blood products must complete specific training for safe transfusion practices and be competent in the transfusion administration process. Always refer to your agency policy for guidelines for preparing, initiating, and monitoring blood and blood product transfusions. These guidelines apply to adult patients only. The transfusion of blood or blood products (see Figure 8.8) is the administration of whole blood, its components, or plasma-derived products. The primary indication for a red blood cell (RBC) transfusion is to improve the oxygen-carrying capacity of the blood (Canadian Blood Services, 2013). A health care provider order is required for the transfusion of blood or blood products. RBC transfusions are indicated in patients with anemia who have evidence of impaired oxygen delivery. For example, individuals with acute blood loss, chronic anemia and cardiopulmonary compromise, or disease or medication effects associated with bone marrow suppression may be candidates for RBC transfusion. In patients with acute blood loss, volume replacement is often more critical than the composition of the replacing fluids (Canadian Blood Services, 2013). Transfusions can restore blood volume, restore oxygen-carrying capacity of blood with red blood cells, and provide platelets and clotting factors. The most common type of blood transfusion is blood that is donated by another person (allogeneic). Autologous transfusion is the transfusion of one’s own blood (Perry et al., 2014). Figure 8.8 Red blood cells and blood IV tubingTransfusion therapy is considered safe, and stringent precautions are followed in the collection, processing, and administration of blood and blood components. However, transfusions still carry risks such as incompatibility, human error, and disease transmission, and blood transfusion must be taken seriously at all times. Incompatibility can be decreased by using irradiated red blood cells or leukocyte-reduced blood. The majority of blood transfusion complications are a result of human error (Perry et al., 2014). Compatibility testing is vital for all recipients of blood or blood products. Recipients must be transfused with an ABO group specific to their own blood type or ABO group-compatible. There are three types of blood typing systems: ABO, Rh, and human leukocyte antigen (HLA). For more information on these, refer to the online resources at the end of this chapter. It is vital to understand what types of blood groups are compatible for transfusions (Canadian Blood Services, 2013). When administering blood and blood products, it is important to know the patient’s values and beliefs regarding blood products. Some groups of individuals, mainly Jehovah Witnesses, will refuse blood transfusions or blood products based on religious beliefs. These individuals will refuse transfusion of whole blood and primary blood components but may accept transfusion of derivatives of primary blood components such as albumins solutions, clotting factors and immunoglobulins. Always assess each individual preference to establish if a blood component is an acceptable treatment to manage their illness or condition (Canadian Blood Services, 2007). When managing blood transfusions, it is important to prevent complications from occurring and to identify issues promptly to manage reactions effectively. Transfusion reactions (mild to life-threatening) may occur despite all safety measures taken. All transfusion reactions and transfusion errors must be reported to the hospital’s transfusion services (blood bank). It is imperative to know what signs and symptoms to look for, and to educate your patient on what to report and when to report potential transfusion reactions. Mild to severe reactions may include (Canadian Blood Services, 2011):
For more information on types of reactions, signs and symptoms, and treatments, review the article adverse events related to blood transfusions, or see the online resources at the end of this chapter. If patient has a blood transfusion reaction, always follow agency policy to manage mild to severe blood reactions. In general, if a reaction occurs, follow the steps outlined in Checklist 73.
In preparation for a blood or blood product transfusion (Alberta Health Services, 2015a, 2015b; Perry et al., 2014; Vancouver Coastal Health, 2008), the steps listed in Checklist 74 must be completed. These steps must be completed before obtaining the blood or blood product from the blood bank.
Checklist 75 provides steps to administering blood and blood products safely in the acute care setting.
