Blood Transfusion Procedures and Reactions

Blood Transfusion Protocols

Assess Laboratory Values

  • Purpose: Assessing lab values is crucial in determining the need for blood transfusions.

Blood Transfusion Procedures

Before Infusion
  1. Verify the Order
    • Must have a physician's order before proceeding with the transfusion.
  2. Obtain Patient Consent
    • Ensure written consent is acquired from the patient before transfusion.
  3. Assess Patient's Condition
    • Check vital signs, urine output, skin color, and any history of transfusion reactions.
  4. Obtain Venous Access
    • Utilize a central line or at least a 20-gauge needle to ensure adequate flow and prevent occlusion.
  5. Obtain Blood Products
    • Fetch the ordered blood products from the blood bank.
  6. Verify Blood Products
    • With another registered nurse, verify patient’s identity by:
      • Name
      • ID number
      • Check blood compatibility
      • Note the expiration time of the blood products.
  7. Transfusion Timing
    • Transfuse as soon as possible after initiating safety checks; blood must be hung within 30 minutes of retrieval from the blood bank, or it must be returned to refrigeration.

Blood Administration Details

Pre-Administration Checks
  • Determine Client's Allergies
    • Important to know any allergies that may affect transfusion.
  • Check Crossmatch
    • Review any previous transfusion reactions using blood records.
  • Infusion Timing
    • Blood must be administered within 30 minutes of receiving it from the blood bank.
  • Medication Policy
    • Never add any medications to blood products.
Key Points for Verification
  • Verify Client's ID
    • Confirm the identity of the patient.
  • Doctor's Order
    • Check physician's order for the transfusion.
  • Blood Bag Labeling & Records
    • Cross-check labels on the blood bag and blood bank transfusion record.
  • Baseline Vital Signs
    • Record baseline vitals and monitor as per facility policy.
  • Equipment
    • Use a #18G or #20G gauge needle for venous access.
    • Administer normal saline IV solution concurrently.
    • Ensure a blood administration set with a filter is available.
  • Potential Reactions Monitoring
    • Severe transfusion reactions typically occur within the first 15 minutes, especially during the first 50cc of infusion.
  • Blood Tubing Maintenance
    • Change blood tubing after 4 hours of use.

Infusion Process

During Infusion
  1. Supplies Required
    • Utilize 0.9% normal saline; no other fluids should be administered as hemolysis can occur.
    • Ensure IV tubing is primed with normal saline only, not blood.
    • Blood administration must occur using Y-tubing with a filter to catch aggregates and contaminants.
    • Medications may never be added to blood products.
  2. Initial Checks
    • Record initial vital signs and temperature prior to starting the transfusion.
  3. Time Frame for Transfusion
    • A blood product must be transfused within 4 hours after removal from refrigeration.
  4. Verification Steps
    • Double-check the following with another RN:
      • Patient’s name
      • Blood bank ID number
      • ABO and Rh compatibility
      • Unit number
      • Expiration date of blood product.
Continued Monitoring
  1. IV Access and Observation
    • Initiate a large bore IV access with an 18G or 20G needle.
    • Assess for any history of previous blood transfusion reactions.
  2. Blood Products Inspection
    • Upon obtaining blood products from the bank, check for:
      • Cloudiness
      • Discoloration
      • Excessive bubbles.
  3. Handling Blood Bags
    • Do not puncture the blood bag; the spike is sharp and designed for ease of access.
  4. Patient Monitoring
    • Remain with the patient for the first 15-30 minutes to monitor for hemolytic reactions, which most frequently occur within the initial 50 mL of the infusion.
    • Monitor vital signs closely, as any changes may indicate a transfusion reaction.
Infusion Rate
  1. Fluid Administration
    • Infuse blood product at a prescribed rate; rapid infusion can lead to fluid overload, a serious complication.

Post-Infusion Process

After Infusion
  1. Discontinue Infusion
    • Once the transfusion is complete, discontinue the infusion, place the blood bag in a plastic bag, and send it to the blood bank along with a carbon copy of the transfusion record.
  2. Documentation Requirements
    • Accurately document the following:
      • Type of product infused
      • Product number
      • Volume infused
      • Time of infusion
      • Any adverse reactions noted during the transfusion.
  3. Fluid Output Record
    • Document the amount of blood (in cc) in the Intake & Output (I&O) records.
Special Notes
  • Normal saline is essential for priming during blood transfusions.
  • Avoid priming with blood to ensure no loss of blood product.
  • Infuse one unit of blood at a time for safety.
  • Special considerations for geriatric patients may include administering only half a unit at a time to prevent hypervolemia.
  • Utilize specialized Y-tubing for administering blood.
  • Acute hemolytic reactions are considered the most severe type of transfusion reaction.

Nursing Interventions for Blood Transfusion Reactions

  1. Management of Shock
    • Initiate treatment for shock if symptoms present.
  2. Blood Sample Collection
    • Draw blood samples for further testing.
  3. Vital Signs Maintenance
    • Maintain blood pressure and prepare to administer IV colloid solutions if necessary.
  4. Accurate I&O Record
    • Document intake and output accurately during the reaction.
  5. Additional Blood Transfusion
    • Do not transfuse additional blood or blood products until new cross-matched units are provided by the blood bank.
  6. Administration of Medications
    • Administer antipyretics as prescribed to manage symptoms.
  7. Transfusion Restriction
    • Do not restart any transfusion until a physician's order has been received.
  8. Immediate Actions for Acute Reactions
    • If acute reactions occur:
      • Stop the transfusion immediately.
      • Maintain IV access with normal saline only.
      • Notify the blood bank and physician without delay.
      • Recheck identity tags and numbers of the blood product.
      • Monitor vital signs and urine output vigilantly.
      • Treat symptoms as directed by the physician.
      • Save the blood bag and the tubing; send them back to the blood bank for investigation.
      • Complete required transfusion reaction reports and document the events in the patient's medical chart.
