Blood Administration Basic Immunology Blood Type A: A Antigen is present on the RBC surface Anti B antibodies in the plasma Blood Type B: B Antigen is present on the RBC surface Anti A antibodies in the plasma Blood Type AB: A&B Antigens are present on the RBC surface No Anti A or B antibodies in the plasma Blood Type O: Neither A or B Antigen is present on the RBC surface Anti A & B Antibodies in the plasma Rh Positive: D Antigen (Rhesus system) is present on the RBC surface Basic Immunology Do not transfuse an antigen to a recipient having antibodies against that antigen A B O C o m p a tib ility D o n o r C e lls R e c ip ie n t W h o le B lo o d RBCs P la s m a A A A, O A, AB B B B, O B, AB O O O A, B, O, AB AB AB A, B, O, AB AB R h P o s itiv e + / - + / - + / - R h N e g a tiv e - - +/ - Thus the Old Adage says: Type AB is the Universal Receiver Type O is the Universal Donor Transfusion Options Homologous Blood: Blood collected from donors for transfusion to another individual Volunteer donors Autologous Blood: Blood collected from the intended recipient. Self donation. Most frequently done for planned surgeries Designated (Directed) Blood: Blood collected from a donor designated by the intended recipient. Compatibility testing is required. Not available at MAH Blood Bank Testing Options Type and Screen (TS): must be within 3 days. This option, types and screens for antibodies Red Blood Cells (RBC): This orders the # of units to be crossmatched. Specimen Labeling Safe transfusions begin with the proper identification of the intended recipient pre transfusion specimen. The following information is required and must be legibly copied (handwritten) directly from the current wristband to the primary sample tube label. • Full name exactly as it appears on wristband including middle initials, JR, Sr, etc • Medical Record Number (U#) • Date and Time Drawn • Initials of Person Drawing Specimen • Initials of Identification Witness Samples not meeting these requirements will not be used under any circumstances. Corrections are not allowed after the sample leaves the patient’s bedside Samples for the blood bank must be verified by a second person who is present while the blood is being drawn and validates the patient’s identity using 2 identifiers. Each person initials the blood tube M o u n t A u b u r n H o s p it a l B lo o d B a n k S p e c im e n - L a b e lin g R e q u ir e m e n t s Surname DOE First Name JOHN J. Pat.

S r . ) Whole Blood Composition: RBCs, plasma which contains plasma proteins (globulins and antibodies) stable clotting factors and a preservative Indication: to treat massive blood loss requiring O2 carrying properties of RBCs along with volume expansion provided by plasma Rate: As rapidly as needed for hemodynamic stability Considerations: never add medications, mix only with NS; Recommend 20 gauge IV or larger. A 22 gauge may be used if the patients access has been evaluated standard Y type infusion set; should increase HCT by 3 points and hemoglobin by 1 point Packed Red Blood Cells Composition: Concentrated RBCs in a preservative Indication: To increase the O2 carrying capacity in symptomatic anemic patients without the need for volume expansion Rate: 1 unit over 2-3 hours but not to exceed 4 hours Considerations: recommend 20gauge or larger access; 22 gauge may be used if access evaluated standard Y set Mix only with NS, Leukocyte Reduced RBCs Composition: RBCs in which the leukocyte # has been reduced and at least 80% of the RBCs remain Indications: To prevent recurrence of febrile, nonhemolytic reactions caused by donor WBCs reacting with recipient WBC Rate: same as PRBCs Considerations: WBC reduction may occur prior to or during the transfusion. If not already done, you must use a special leukocyte reduction filter Irradiated RBCs Composition: Blood products which have been exposed to a measured amount of radiation thereby rendering the donor lymphocytes incapable of replication Indication: To prevent graft vs host disease in patients receiving blood products containing viable WBCs. Used for patients at risk for GVHD: severe combined immunodeficiency; acute leukemia, multiple myeloma Rate: same as RBCs Considerations: Irradiation is performed by the blood collection center and an “irradiated” label is placed on the bag. There is no radiation risk to the transfusionist or the recipient Platelets Composition: Platelet Pheresis: Platelet rich plasma from a single donor Pooled Platelets: Platelets pooled from 4-6 units Indication: To control or prevent bleeding associated with deficiencies in platelet # or function. Used prophylactically PLT < 10,000 - 20,000 If evidence of bleeding with PLT < 50,000 Rate: determined by volume tolerance but must be infused within 4 hours Consideration: If need Leukocyte reduced, there is a different filter. WBC reduction may occur prior to transfusion; if not a filter is required to reduce Fresh Frozen Plasma Composition: 91% water, 7% proteins (albumin, globulins, antibodies, and clotting factors) Indications: To increase the level of clotting factors in patients with a demonstrated deficiency Rate: 10ml/min or more slowly if overload is a potential problem Considerations: Contains no RBCs so cross-matching is not required but ABO compatibility is required Albumin Composition: 96% albumin 4% globulin's and other proteins from plasma. 5% which is oncotically the same as plasma. 25% which pulls fluid intravascularly (both from Pharmacy) Indication: To provide volume expansion where crystalloids are not adequate. Rate: 1-10ml/min or faster if in shock Considerations: With 25%, can cause increased blood volume and increased blood pressure due to its ability to draw fluid from the intravascular space There are no ABO blood antibodies present Administration set may be supplied with the albumin Keys to the Transfusion Process 1. Ensure order is written clearly 2. Ensure Consent Form is signed 3. Assess IV access 4. Obtain pre transfusion vital signs After you have checked these things and are sure you are ready to administer the blood……… Enter a Transport Request to pick up blood Blood Consent MD Responsibility May sure the I authorize is checked before transfusing!!!! Verifying Blood Products •With a SECOND person, compare the following: name on blood tag with order page of medical record unit number on blood tag with medical record (computer if not in record) blood type in patient chart, blood tag and blood bag blood number on blood tag and that on bag patient name and unit number on blood tag with ID bracelet AT THE PATIENT’S BEDSIDE check expiration date on bag and tag Compare the following information on the tag with the transfusion report * Name * Blood Product # * Medical Record # * Expiration date * Blood type NOW YOU CAN SIGN THE TRANSFUSION REPORT Blood Tag Blood Product number Type of product and blood type Patient’s name & medical record # Expiration date and time Compare to medical record and patient ID bracelet Keys to the Transfusion Process • Explain to patient symptoms to report to RN • Obtain baseline vital signs, at 15min, 1 hour, and at completion • Spike bag with Y set and NS on the second spike More than I unit to hang? change tubing with each bag Q4hrs • Infuse at 1ml/min x 15min, stay with patient x 10minutes • If no reaction, rate to 5-10ml/min; if at risk for overload to 2-4ml/min • Complete transfusion report Transfusion Report Compare with blood tag Documents vital signs and times per policy What now, my patient needs to go to…….. X_RAY CT SCAN If a patient needs to go off the unit during a transfusion…… They must be accompanied by an RN /MD GI UNIT Symptoms of a Transfusion Apprehension convulsions Reaction Feelings of Impending doom Tachy / Bradycardia Hypo/hypertension Cyanosis Flushing Edema Bleeding Tachypnea Apnea Dyspnea Cough Hypoxia Wheezing Rales Nausea Vomiting Abd pain Diarrhea Renal: Oliguria Renal failure Colored urine Skin: Rash Itch Diaphoresis Fever Chills Muscle aches Back pain Chest pain Headache Heat at IV site Transfusion Reactions A Transfusion Reaction is any unfavorable event occurring during or following transfusion of blood, blood components, or blood derivatives which can be related to that transfusion. Every transfusion carries the risk of alloimmunization as well as transmission of disease It is essential that when a transfusion reaction is suspected, 1. Stop the transfusion immediately 2. Re-Verify that the correct unit is being transfused to the intended recipient. 3. Call the MD for orders 4. Notify the Blood Bank Acute Hemolytic Reaction Cause: Infusion of ABO incompatible blood; Antibodies in the recipient’s plasma attach to antigens on the transfused blood causing RBC destruction SX: chills, fever, low back pain, flushing, tachycardia, tachypnea, hypotension, vascular collapse, hemoglobinuria, bleeding, ARF, shock, cardiac arrest, death Mgmt: Stop the infusion, reverify identity,& call MD Treat shock; draw pink top tube for blood bank with proper identification, send urine to lab, maintain BP with crystalloids, insert catheter and monitor UOP, Do not restart transfusion, Send blood bag and set with reaction form to blood bank Prevent: Meticulous verification of blood products and patient identification Febrile, Non Hemolytic Cause: Sensitization between antibodies in recipient and and antigens on WBC and platelets SX: Sudden chill, fever (1C or 1.5 F), headache, flushing, anxiety, muscle pain Mgmt: STOP the transfusion, reverify identity & call MD Give antipyretic Do not restart transfusion Send blood bag &set to the blood back with reaction form Prevention: Consider leukocyte-reduced blood products Mild Allergic Cause: sensitivity to foreign plasma proteins SX: flushing, itching, hives Mgmt: STOP the transfusion Reverify identity, & Call MD Give antihistamine as directed May restart only if sx are mild Send the blood bad and infusion set to the Blood Bank with the Blood reaction form if deemed to be a suspected reaction Prevention: Prophylactic antihistamines Anaphylactic Reaction Cause: Infusion of IgA proteins to IgA deficient recipient who has developed IgA antibody Sx: anxiety, urticaria, wheezing, cyanosis, shock, and possible cardiac arrest Mgmt: STOP the transfusion Epinephrine 0.4ml of 1:1,000 SC CPR if indicated Do not restart transfusion Prevention: Transfuse washed RBC products and IgA deficient plasma products Circulatory Overload Cause: Fluid administered faster than the circulation can accommodate Sx: cough, dyspnea, rales, headache, HTN, tachycardia, distended neck veins Mgmt: STOP the transfusion re-verify identity, call MD Place in high fowlers Administer diuretics, O2, morphine Send blood bag and set to Blood Bank with reaction form Prevention: Adjust volume and rate based on clinical status Have unit split (NOT DONE AT MAH) Sepsis Cause: Transfusion of contaminated blood components Sx: rapid chills, high fever, vomiting, diarrhea, marked hypotension, and shock Mgmt: STOP the transfusion, re-verify identity & Call MD Obtain culture of patient and send bag for further study Antibiotics, IV fluids, vasopressors, steroids Send blood bag and set to blood bank with reaction form Prevention: Sterile technique Do not interrupt transfusion Infuse within 4 hours of starting time and prior to component expiration TRALI Transfusion-related acute lung injury Cause: WBC antibodies in the blood component cause massive leakage of fluids and proteins into the lungs SX: Severe respiratory distress, pulmonary edema, hypoxia, SOB (can occur within 6 hours of transfusion) Mgmt: STOP the transfusion, re-verify identity & call MD Aggressive respiratory support Send blood bag and set to blood bank with reaction form Delayed Reactions (Notify the Blood Bank) Delayed Hemolytic Hepatitis B or C Post Transfusion Purpura (PTP) Iron Overload Graft vs Host disease HIV
