Blood Transfusion Therapy Nursing Interventions & Management

Blood transfusion (BT) therapy transfuses whole blood or the specific blood component a patient lacks. Here are the concepts behind it and the nursing management before, during, and after.

What is Blood Transfusion?

A blood transfusion transfers donated blood or blood components into a patient's bloodstream. It replaces blood lost in surgery, injury, or illness and treats conditions like anemia, clotting disorders, and certain cancers. It can deliver whole blood or specific components, red blood cells, platelets, plasma, or cryoprecipitate, depending on need.

Before transfusing, the donor's blood type must be compatible with the recipient's to prevent clumping and hemolysis, which can be fatal. Blood types (A, B, AB, O) are set by specific antigens on red blood cells. The Rh factor is another antigen: people are Rh-positive or Rh-negative, and Rh-negative individuals must receive Rh-negative blood.

Donors are screened and tested for HIV, hepatitis B and C, syphilis, and West Nile virus, and evaluated on health history and lifestyle. Patients can pre-donate their own blood for future use (autologous transfusion), which reduces infection and mismatch risk.

Indications of Blood Components

• Whole blood is for patients needing both increased oxygen-carrying capacity and volume restoration, especially when there is no time to prepare specific components.
• Packed red blood cells contain 100% of the erythrocytes, 100% of the leukocytes, and 20% of the plasma from one unit of whole blood. Used for anemia, cardiovascular failure, or GI bleeding when red cell count must rise without the added fluid of whole blood. Transfuse over 2 to 3 hours; if the patient cannot tolerate the volume within 4 hours, the blood bank may divide the unit. One unit raises hemoglobin by approximately 1% and hematocrit by 3%.
• Leukocyte-poor packed RBCs are for patients with prior febrile non-hemolytic reactions; reducing leukocytes minimizes febrile reactions.
• Platelets treat or prevent bleeding in patients with low or dysfunctional platelets, either HLA (human leukocyte antigen) matched or unmatched. Give as rapidly as tolerated, usually 4 units every 30 to 60 minutes, with each unit raising the count by 6,000 to 10,000/mm³. Poor increases can come from alloimmunization, bleeding, fever, infection, autoimmune destruction, and hypertension.
• Granulocytes (basophils, eosinophils, neutrophils) help patients with severe neutropenia not responding to antibiotics. Indicated for infected, severely granulocytopenic patients (less than 500/mm³) expected to have prolonged granulocyte suppression.
• Plasma is for volume expansion and for low plasma proteins or clotting factors:
  • Fresh frozen plasma (FFP) contains all coagulation factors, including factors V and VIII, for coagulation deficiencies, liver disease, or rapid anticoagulation reversal. Give as rapidly as tolerated, since coagulation factors degrade after thawing.
  • Single donor plasma contains all stable coagulation factors but reduced factors V and VIII. Preferred for reversing Coumadin (warfarin)-induced anticoagulation.
• Albumin is a plasma protein contributing to oncotic pressure, used to expand volume in hypovolemic shock or hypoalbuminemia.
• Cryoprecipitate is rich in factor VIII, fibrinogen, factor XIII, and fibronectin. Indicated for hemophilia A, Von Willebrand's disease, disseminated intravascular coagulation (DIC), and uremic bleeding.
• Factor IX concentrate is concentrated factor IX, pooled, fractionated, and freeze-dried from large plasma volumes, for hemophilia B. Carries a high hepatitis risk from multi-donor pooling.
• Factor VIII concentrate is pooled, fractionated, and freeze-dried for hemophilia A, and heat-treated to reduce hepatitis and HIV transmission.
• Prothrombin complex contains prothrombin and factors VII, IX, X, and some factor XI, for congenital or acquired deficiencies of these factors and for warfarin reversal.

Administering a Blood Transfusion

Equipment

• Blood product
• Blood administration set (tubing with in-line filter and Y for saline)
• 0.9% normal saline for IV infusion
• IV pole
• Clean gloves and additional PPE as indicated
• Hypoallergenic tape
• Second RN for verification of blood product and patient information

Procedure

Pre-transfusion preparation and verification

1. Verify the medical order and consent, confirm informed consent is documented, and note any pretransfusion medication orders. Give pretransfusion medications at least 30 minutes before starting.

2. Gather equipment at the bedside.

3. Perform hand hygiene and put on PPE.

4. Identify the patient using at least two identifiers.

5. Prepare the patient: explain the procedure, ensure privacy, ask about previous transfusion reactions, and tell them to report any unusual symptoms immediately.

Setup and initiation

6. Prime the administration set with normal saline.

7. Initiate venous access if not in place, and connect the set.

8. Obtain the blood product from the blood bank per policy, handling and transporting it properly. Never warm blood in a microwave; use a blood-warming device if needed.

9. Verify with two nurses the medical order, informed consent, patient identification number, name, blood group, type, and expiration date, and inspect the product for clots or abnormalities.

10. Take baseline vital signs as a reference point.

11. Prepare for infusion: put on gloves, set up the infusion device, prime the blood side of the set, then remove gloves. Confirm the device is appropriate for blood.

Transfusion administration

12. Start slowly (25–50 mL for the first 15 minutes) and stay with the patient to watch for immediate reactions.

13. Monitor for flushing, dyspnea, itching, hives, or unusual comments.

14. Increase the rate if no reaction occurs in the initial period, completing the transfusion within the prescribed time and never exceeding 4 hours.

15. Reassess vital signs 15 minutes after starting and periodically thereafter per policy.

16. Maintain the flow rate, adjusting for the patient's condition and response.

17. Monitor for reactions. If one is suspected, stop immediately, replace the blood tubing with new tubing primed with saline, and notify the physician and blood bank.

Post-transfusion care

18. Complete the transfusion: flush the line with saline, take final vital signs, and dispose of equipment per policy.

19. Ensure patient comfort, remove equipment, and perform hand hygiene.

20. Document the blood product given, the patient's condition throughout (vital signs, complications or reactions, IV site assessment), and record the transfusion volume and other IV fluid intake on the intake and output record.

Monitoring for unexpected situations

• Fever without other symptoms. Notify the primary care provider, who may order acetaminophen and an antihistamine.
• Shortness of breath and crackles. Compare vital signs to normal, get a pulse oximetry reading, and notify the provider, who may order a diuretic or reduce the rate.
• Transfusion reaction. Stop immediately, replace the tubing, notify the provider and blood bank, and send the blood unit and tubing to the lab. Perform additional diagnostic tests as needed.

Managing Transfusion Reactions

To prevent reactions, verify patient identification meticulously and inspect products for abnormalities. Start slowly and observe closely, especially during the first 15 minutes. Transfuse within 4 hours and change tubing regularly to limit bacterial growth. Screen donors and irradiate products to prevent infectious disease and graft-versus-host disease. Warm units to prevent hypothermia and use microaggregate filters to remove leukocyte and platelet aggregates.

Allergic Reaction

From sensitivity to plasma proteins or donor antibodies reacting with recipient antigens. Assess for flushing, rash or hives, pruritus (itching), and laryngeal edema causing difficulty breathing. Interventions:

• Stop the transfusion immediately.
• Give antihistamines and corticosteroids as prescribed.
• Provide oxygen and airway management for difficulty breathing.
• Monitor closely for symptom progression.

Febrile Non-Hemolytic Reaction

The most common symptomatic complication, from hypersensitivity to donor white cells, platelets, or plasma proteins. Symptoms: sudden chills and fever, flushing, headache, anxiety. Interventions:

• Stop the transfusion temporarily and notify the physician.
• Give antipyretics as prescribed.
• Restart slowly after symptoms subside, under close observation.
• Consider premedication with antipyretics and leukocyte-poor products for future transfusions.

Septic Reaction

From blood or components contaminated with bacteria. Symptoms: rapid-onset chills, vomiting, marked hypotension, and high fever. Interventions:

• Stop the transfusion immediately.
• Give broad-spectrum antibiotics as prescribed.
• Provide supportive care with fluids, vasopressors, and corticosteroids as needed.
• Send the product and tubing to the lab for culture.

Circulatory Overload

When blood is given faster than the circulatory system can handle. Assess for rising venous pressure, dyspnea, crackles or rales, distended neck veins, cough, and elevated blood pressure. Interventions:

• Stop the transfusion and sit the patient upright.
• Give diuretics and oxygen as prescribed.
• Monitor vital signs and respiratory status closely.
• Reduce the rate and volume for future transfusions.

Hemolytic Reaction

From infusing incompatible blood products. Symptoms: low back pain (the first sign, from the kidneys' inflammatory response to incompatible blood), chills, feeling of fullness, tachycardia, flushing, tachypnea, hypotension, bleeding, vascular collapse, and acute renal failure. Interventions:

• Stop the transfusion immediately and notify the physician.
• Maintain IV access with saline to support urine output.
• Provide supportive care for hypotension and renal failure with fluids and medications as prescribed.
• Monitor for shock and disseminated intravascular coagulation (DIC).
• Send the product and tubing to the lab.

Nursing Diagnoses

• Ineffective Breathing Pattern, in allergic reaction or circulatory overload, with dyspnea, tachypnea, and accessory muscle use.
• Decreased Cardiac Output, in hemolytic reaction or circulatory overload, with hypotension, tachycardia, and decreased peripheral pulses.
• Fluid Volume Deficit, in septic or hemolytic reactions, with hypotension, decreased urine output, and dry mucous membranes.
• Fluid Volume Excess, in circulatory overload, with distended neck veins, crackles, and edema.
• Impaired Gas Exchange, in circulatory overload or allergic reaction, with cyanosis, oxygen desaturation, and altered arterial blood gases.
• Hyperthermia, in febrile non-hemolytic or septic reactions, with elevated temperature, chills, and flushed skin.
• Hypothermia, from rapid transfusion of cold products, with low temperature, shivering, and altered mental status.
• Risk for Infection, in septic reaction, with high fever and positive blood cultures.
• Risk for Injury, in allergic or hemolytic reactions, with hypotension, dizziness, and confusion.
• Acute Pain, in hemolytic reactions and vascular complications, with low back pain, abdominal pain, and headache.
• Impaired Skin Integrity, in allergic reactions, with rash, hives, and pruritus.
• Impaired Tissue Perfusion, from decreased cardiac output or hemolytic reactions, with pallor, weak pulses, and cyanosis.

Nursing Interventions

If a transfusion reaction occurs:

1. Stop the transfusion immediately. Do not flush the tubing, which would deliver the remaining blood and could worsen the reaction.

2. Disconnect the administration set from the IV catheter. Call for help, obtain vital signs, and auscultate heart and breath sounds. Early recognition is crucial in respiratory distress and shock.

3. Maintain IV catheter patency with new normal saline and new tubing, then notify the primary provider once you have stopped the transfusion, assessed the patient, and hung the saline. This keeps IV access open for emergency medication.

4. Place the administration set and blood product container, with the blood bank form attached, in a biohazard bag and send it to the blood bank immediately for analysis.

5. Obtain blood and urine specimens per institution policy. Draw blood from the extremity opposite the transfusion site. Blood banks typically require specimens for type and crossmatch comparison, free hemoglobin, and serum bilirubin. Send a urine sample to check for hemoglobinuria, a sign of acute hemolytic reactions.

6. Continue monitoring vital signs at least every 15 minutes to catch any worsening quickly.

7. Administer medications as prescribed, which vary by reaction type.

Patient teaching

• Symptoms of a reaction. Explain the signs (fever, chills, rash, itching, shortness of breath, back pain) and tell the patient and family to notify staff immediately if any occur during or after.
• IV site awareness. Have them report tenderness, redness, swelling, or discomfort at the insertion site without delay, as these can signal infection or infiltration.
• Continuous monitoring. Stress reporting promptly if the set disconnects or the catheter dislodges, so complications are prevented.

Evaluation

• Check the response to transfusion: changes in blood pressure and oxygenation, improved color, or signs of fluid overload.
• Monitor for signs of a transfusion reaction.
• Evaluate the IV site for infiltration, phlebitis, infection, or inflammation.
• Check labs such as complete blood count to gauge therapy effectiveness or a reaction.
