HANDOUT on NURSING MANAGEMENT FOR CLIENT RECEIVING BLOOD TRANSFUSION By: John Arbie T. Tattao, RN • Blood Groups A. Erythrocytes carry antigens, which determine the different blood groups. B. Blood-typing systems are based on the many possible antigens, but the most important are antigens of the ABO and Rh blood groups because they are most likely to be involved I transfusion reactions. 1. ABO typing • Antigens of system are labelled A and • Absence of both antigens results in type O blood • Presence of both antigens is type AB • Presence of either A or B results in type A and type B respectively • Nearly half the population is type O, the universal donor

 Antibodies are automatically formed against the ABO antigens not on person’s own RBC’S; transfusion with mismatched or incompatible blood results in a transfusion reaction

2. Rh typing • Identifies presence or absence of Rh antigen (Rh positive or Rh negative). • Anti-Rh antibodies not automatically formed in Rh-negative person, but if Rhpositive blood is given, antibody formation starts and a second exposure to Rh antigen will trigger a transfusion reaction.

Important for Rh-negative woman carrying Rh-positive baby; first pregnancy not affected, but in a subsequent pregnancy with an Rhpositive positive baby, mother’s antibodies attack baby’s RBCs.

Blood Transfusion and Component Therapy BLOOD TRANSFUSION – the introduction of whole blood components of the blood (plasma, serum, erythrocytes, or platelets) into the venous circulation. Purposes: a. To increase the circulating blood volume as in shock due to haemorrhage b. To increase red cell volume of hemoglobin content of the blood as in anemia c. To increase WBC content of the blood as in agranulocytosis and leucopenia d. To increase the quantity of protein malnutrition, excessive loss of protein from burns or vesicular skin diseases A. Blood and blood products 1. Whole blood: provides all components > 500 ml: 200 ml RBC and 300 ml Plasma a. Large volume can cause difficulty: 12-24 hours for Hgb and hct to rise b. For massive blood loss and exchange transfusion in neonates c. Complications: volume overload, transmission of hepatitis or AIDS, transfusion reaction, infusion of excess potassium and sodium, infusion of anticoagulant (citrate) used to keep stored blood from clotting.

2. Packed Red blood cells > 350 – 400 ml: 200 – 250 ml RBC and 150 ml Plasma and additive solution (saline, glucose, mannitol) a. Provide twice the amount of Hgb as an equivalent amount of whole blood. b. Indicated in cases of blood loss, pre and post-op clients, and those with incipient congestive failure c. Complications: transfusion reaction (less common than with whole blood due to removal of plasma protein) 3. Fresh frozen plasma > 200 – 250 ml: contains all coagulation factors and 250 mg of fibrinogen a. Contains all coagulation factors including V and VIII b. To expand plasma volume, treat post operative hemorrhage or shock and correct coagulation factor deficiencies c. Can be stored frozen for 12 months; takes 20 minutes to thaw d. Hang immediately upon arrival to unit (Rationale: loses its coagulation factors rapidly) 4. Platelets > 30 – 60 ml: half of the number of platelets originally found in 1 unit whole blood a. Will raise recipient’s platelet count by 10,000/mm3 b. For thrombocytopenia, acute leukemia, to restore platelet count preoperatively. b. Pooled from 4-8 units of whole blood c. Single-donor platelet transfusions may be necessary for clients who have developed antibodies; compatibility testing may be necessary 5. Factor VIII fractions (cryoprecipitate): contains Factors VIII, fibrinogen, and XIII > Frozen 20 ml unit contains mostly coagulation factor VIII and 250 mg fibrinogen a. For hemophilia A 6. Volume expanders: albumin; percentage concentration varies (50-100 ml/unit) > Serum albumin and Plasma Protein Fraction (PPF) > 25% albumin in 50 ml and 100 ml units > 5% albumin and PPF comes in 250 ml units a. For hypovolemia and hypoproteinuria b. Hyperosmolar solutions should not be used in dehydrated clients 7. Granulocytes > Contains mostly granulocytes and RBC’s, plasma, and platelets a. For severe gram negative infection or severe neutropenia, unresponsive to routine forms of therapy in immunosuppressed patients B. Nursing Interventions for patients receiving Blood Transfusion:

Nursing Responsibility Prior to Blood Transfusion 1. Verify doctor’s order and make a treatment card Rationale: To avoid mistakes 2. Assess client for history of previous blood transfusions and any adverse reactions. 3. Request blood/blood component from hospital blood bank to include blood typing and cross matching 4. Ensure that the adult client has an 18- or 19- gauge IV catheter in place Rationale: Large bore needle is indicated for BT since blood is viscous. 5. Initiate an IV line with appropriate IV catheter with 0.9% NaCL (PNSS). Rationale: To flush out tubing and Keep IV open (KVO) 6. Ensure that the blood should be transfused not more than 20 minutes from the time it arrives from the blood bank Rationale: To prevent untoward blood reaction 7. Have a doctor and a nurse or at least two nurses countercheck the compatible blood to be transfused: a. Name and Identification number b. Client’s blood group and Rh type c. Donor’s blood group and Rh type d. Cross-match compatibility e. Blood unit and serial component f. Expiration date of blood product Rationale: To prevent any problem in relation to transfusion 8. Take baseline vital signs before initiating transfusion. Rationale: To compare any change in vital signs before and during the BT 9. Give pre medications 30 minutes before transfusion if any is ordered Rationale: To prevent minor allergic reaction Nursing Responsibility during Blood Transfusion: 1. Start transfusion slowly (2 ml/minute) 2. Stay with the client during the first 15 minutes of the transfusion and take vital signs frequently Rationale: Transfusion reactions occurs during the first 10 – 15 minutes of transfusion 3. Maintain the prescribed transfusion rate a. Whole blood: approximately 3-4 hours b. RBCs: approximately 2-4 hours c. Fresh frozen plasma: as quickly as possible d. Platelets: as quickly as possible e. Cryoprecipitate: rapid infusion d. Volume expanders: volume-dependent rate 4. Observe the patient for any untoward signs and symptoms (ICEFUD) a. Itchiness b. Chills c. Elevated temperature d. Flushed skin e. Urticaria f. Dyspnea

If any occurs, institute (SPR) STOP transfusion, OPEN IV line

with PNSS, and REPORT to the physician 5. Swirl the bag once in a while Rationale: To mix the solid and liquid elements of the blood. RBC tends to settle at the bottom of the solution while the plasma rises to the top as the blood bag hangs 6. If blood is consumed, close roller clamp of BT set then disconnect from IV line then regulate the IVF as ordered Nursing Responsibility after Blood Transfusion 1. Continuously monitor the patient for signs of blood transfusion reactions. 2. Carry out post BT order such as re-check Hgb and Hct level, bleeding time,RBC and platelet count 3. Document observations and interventions done a. Blood component unit number (apply sticker if available) b. Date infusion starts and ends c. Type of component and amount transfused d. Client reaction and vital signs e. Signature of transfusionist C. Blood Transfusion Reactions (HAPCAT) A. Hemolytic Reaction 1. Causes: a. ABO incompatibility b. Rh incompatibility c. Use of dextrose solutions 2. Mechanism a. Antibodies in recipient plasma react with antigen in donor cells. Agglutinated cells block capillary blood flow to organs. 3. Occurrence: a. Acute: first 5 min after completion of transfusion b. Delayed: days to 2 weeks after 4. Signs and symptoms a. Headache b. Lumbar or sternal pain c. Nausea and vomiting d. Fever and chills e. Flushing and heat along vein f. Restlessness g. Dysnea h. Signs of shock; renal shutdown i. DIC 5. Nursing Intervention a. Stop transfusion (Standard Operating Procedure-SOP) b. Continue saline IV c. Notify Physician d. Send blood unit and client blood sample to lab e. Administer isotonic fluid solution as ordered. To prevent acute tubular necrosis and counteract shock

d. Watch for hemoglobinuria e. Treat or prevent shock, DIC, and renal shutdown f. Monitor Vital signs and intake and output B. Allergic Reaction 1. Causes a.
