1 Blood Request To Transfusion - Practical Aspects
Presented by – Dr. Rajesh Kucheria Medical Director, Arpan Chain Of Blood Banks

2 ARPAN’S QUALITY POLICY
Arpan is committed to deliver highest level of quality standard in its products and services. We believe that this can be achieved only with continuous improvements, global bench marking & ceaseless effort to learn. We aim to set new standards for quality in our region & become a role model for all those who want to contribute in this sphere of public health.

3 PREFACE Emerging from Arpan’s vision, this document is a very specific effort towards bringing entire chain of professionals working in blood transfusion cycle to a common understanding of the complex process. Starting with the point in the hospital where it is decided to opt for blood transfusion to the logical conclusion of patients acceptance of this emergency drug, every step is discussed with detailed medical understanding as well as administrative check points. The purpose is to ensure that there is no error whatsoever at any point in this lifesaving mechanism. We are sure, clinicians, paramedical staff, blood banking staff and administrative professional touching this process would find this document very useful and pragmatic for their day to day work and will make entire cycle error free and thus safest. We would be more than happy to receive your feedback / suggestions on this on - Arpan Family -

7 BLOOD REQUEST

8 INTENTIONALLY LEFT BLANK

9 REQUISITION FORM FILLING
1 Patient information Always write patient’s full name as multiple requests come to blood bank from many hospitals & there are chances of two requests of same name & surname from two different hospitals. Compulsory write patient’s blood group on form. If any discrepancy is noted in blood group written on requisition form and blood group detected in blood bank on patient’s sample, it can be resolved & right blood can be issued to the patient. Product requirement Always write date & time of requirement of blood / component unit, so that unit can be reserved, if it is going to be available meanwhile. Hospital information Always write treating doctor’s name & mobile no. on requisition form, so that in case of any problem or doubt, it can be resolved by talking with him. Always give hospital seal on requisition form. It is legally compulsory & possible malpractices can be avoided.

10 BLOOD SAMPLE COLLECTION
2 BLOOD SAMPLE COLLECTION Always remove needle & then pour blood in sample bulb Never send sample in syringe Always label sample bulb properly with patient’s full name & hospital name Patient’s Sample Label Sticker Patient’s Full Name First Middle Surname Hospital

11 window period reduction (When tested by NAT technology)
3 NAT TEST NAT testing lab is established at Arpan Blood Bank, Nashik. It is 2nd Stand alone blood bank in the country to start NAT testing facility. NAT tested blood will be available at all centres of Arpan blood bank across State. NAT – Nucleic Acid Amplification test used to detect HIV, HBV & HCV infection. It is most advanced technology used Worldwide. In this test, viral RNA is captured, amplified & detected. As it detects genetic material, detection is accurate & very early than conventional methods (ELISA & Cheminileuscence). window period reduction Infection Window period (When tested by ELISA technology using best 4th generation kits) Window period (When tested by NAT technology) HIV 20.3 days 5.6 days HBV 53.3 days 24.6 days HCV 58.3 days 4.9 days Pilot Study – The first Indian study for NAT testing shows that 1 in 1,528 blood units are found to be positive for any of the Three viruses which were seronegative by ELISA technology. A pilot study at AIIMS among 5,818 donors shows that 1 in 1,164 blood units were found to be positive for any of the three viruses which were seronegative by ELISA technology. There is no reported case of either of three infections after transfusion of NAT tested blood. Cost- As NAT test is done in addition to routine ELISA test, extra cost is added for NAT tested unit. But the cost is negligible considering the physical, mental trauma & economic loss for treatment of these diseases.

12 GUIDELINES FOR USE OF BLOOD COMPONENTS
4 GUIDELINES FOR USE OF BLOOD COMPONENTS Transfusion Indication Options Desired Effect Preference Reasons Packed Red Cells In Additive Solution (PCV) Hb by 1 g% HCT by 3% Least chances of transfusion reactions as total plasma is removed. Viability of RBCs is better. Platelets and Plasma can be utilised for another patient. To Increase HB% 2. Whole Blood (WB) Hb by 1 g% HCT by 3% More chances of transfusion reactions due to plasma proteins. It is like unnecessary multidrug therapy. To Replace Blood Loss 2. Whole Blood 1. PCV As per volume of PCV - If you want to replace blood loss more than two liters quickly. - If you want to replace blood loss less than two liters. As per volume of WB To Increase Platelet Count Single Donor Platelets (SDP) Recipient is exposed to single donor. Leucoreduced platelets are obtained so risk of transfusion reaction and platelet refractoriness is reduced. Increases Platelet count by 50,000- 70,000/ml per unit Increases Platelet count by 5,000- 8,000/ml per unit 2. Random Donor Platelets (RDP) Recipient is exposed to many donors. Risk of alloimmunization and so platelet refractoriness Chances of transfusion reaction are more as leucoreduction is not always possible.

13 GUIDELINES FOR USE OF BLOOD COMPONENTS Transfusion Indication
5 GUIDELINES FOR USE OF BLOOD COMPONENTS Transfusion Indication Options Desired Effect Preference Reasons 1. Fresh Frozen Plasma (FFP) To Give Clotting Factors Raises all clotting factors (I to XIII) -Supplies Albumin Fresh Frozen Plasma can be given when all clotting factors are required. It also supplies Albumin. 2. Cryoprecipitate (CRYO) -Raises Factor VIII, VWF and Factor XIII & Fibrinogen If we want to supply factor VIII (AHF), VWF or Factor XIII, Cryoprecipitate should be preferred over FFP as volume is reduced & so chances of transfusion reactions. 1. PCV + RDP / SDP As per individual PCV & RDP or SDP Fresh blood is not an option because blood needs to be preserved at 2-60C, till testing is done and % platelets become non viable at 2-60C. Hence this blood will not supply viable platelets. You will only get RBCs & Plasma from Fresh Blood. To Increase HB% And Platelet Count 2. Fresh Blood Only increase in HB% as per Whole Blood Fresh Blood is not an option because all labile clotting factors get destroyed at 2-60C within 6 hrs. And it usually takes more than 6 hrs from collection to issue. Hence fresh blood will not supply clotting factors. To Increase HB% And Clotting Factors 1. PCV + FFP /CRYO As per individual PCV & FFP or CRYO 2. Fresh Blood Only increase in HB% as per Whole Blood

14 PLASMA BY APHERESIS (PL-A)
6 PLASMA BY APHERESIS (PL-A) In western India, Arpan blood bank, Nashik is the only blood bank to have Plasma Apheresis facility. As platelets are collected by apheresis, 500ml plasma can also be collected by apheresis. The unit of 500 ml plasma collected by apheresis is called PL-A. Advantages of plasma by Apheresis (PL-A). As plasma is collected & frozen within 2 hours, the quality of product is much superior & the yield of clotting factors is much high than routine FFP. The desired effect of 4 FFP unit is achieved by single unit of PL-A. So the risk of exposure to four different donors & therefore TTI is significantly reduced. The same donor can donate another unit of PL-A after 15 days.

15 BLOOD GROUPS, CROSSMATCHING & COMPATIBILITY

16 INTENTIONALLY LEFT BLANK

17 BLOOD GROUPS ABO blood grouping system Rh blood grouping system
7 ABO blood grouping system ABO Blood Group Antigens on RBCs Antibodies in plasma O - A & B A B AB Rh blood grouping system Rh Blood Group Antigens on RBCs Antibodies in plasma Rh Positive D - Rh Negative ABO antibodies are naturally occurring i.e. opposite antibody (to antigen on RBCs) appears in plasma naturally within few months after birth. In contrast Rh antibodies are not naturally occurring. They are immune antibodies. They develop against antigenic stimulus i.e. when Rh positive RBCs enter in circulation of Rh negative person.

18 CROSSMATCHING Patient sample Patient’s plasma (Antibody)
8 Patient sample Patient’s plasma (Antibody) P Patient’s RBCs (Antigen) Blood unit (Donor) Sample Donor RBCs (Antigen) Donor plasma (Antibody) D Major crossmatch Minor crossmatch If Major crossmatch is incompatible, then donor cells (which are less in volume) will react with antibodies in patient’s plasma (which is large in volume) & will get destructed completely to cause serious hemolytic reaction. So it is called Major. If Minor crossmatch is incompatible, then donor’s plasma (which is less in volume) will get diluted in patient’s plasma (which is large in volume) and there are less chances of reaction between antibodies in donor’s plasma with antigens on patients cells & so least chance of hemolytic reaction. So it is called Minor.

19      COMPATIBILITY Results : Interpretation :
9 Results : Agglutination reaction Incompatible No agglutination reaction Compatible Interpretation : Major Minor Compatibility Compatible groups Optional groups (Can be given in emergency, when compatible group is not available.) Incompatible groups (Can not be transfused) The unit is called compatible if it is compatible for both blood grouping systems i.e. ABO blood group system Rh blood group system

34 PLATELET COMPATIBILITY
24 PLATELET COMPATIBILITY ABO antigens are not usually expressed on platelets. They are expressed on platelets in only 7% population, in which they are expressed weakly and on some platelets. So platelet cross matching is not applicable for platelet transfusion. Platelet can be transfused across group safely i.e. any group platelets can be given to any group patients.

38 'Rh negative' person should receive ‘Rh negative’ whole blood and PCV.
28 Rh COMPATIBILITY ‘Rh positive’ patient can receive ‘Rh positive’ as well as ‘Rh negative’ blood or blood components. 'Rh negative' person should receive ‘Rh negative’ whole blood and PCV. For plasma & platelet transfusion, when ‘Rh negative’ units are not available, ‘Rh positive’ units can be transfused weighing the need of transfusion and risk of Rh alloimmunisation. While transfusing ‘Rh positive’ unit to ‘Rh negative’ woman with child bearing potential, Rh Ig prophylaxis should be given. For cryoprecipitate transfusion Rh compatibility is not applicable.

39 COMPATIBILITY & SELECTION OF UNIT FOR NEONATAL TRANSFUSION
29 COMPATIBILITY & SELECTION OF UNIT FOR NEONATAL TRANSFUSION Neonate: Patient under the age of 4 months are neonates for blood transfusion purpose. Blood Request: Write compulsory ‘whether you suspect HDN or not’ on requisition form . Blood Samples: Send blood samples of both – Baby Mother Compatibility Testing: First direct coomb’s test (DCT) on baby’s RBCs & indirect commb’s test (ICT) on maternal plasma are performed to r/o HDN. Test Results DCT on baby’s RBCs + ICT on maternal plasma Clinically suspected case of HDN Interpretation: No e/o HDN e/o HDN

40 ABO COMPATIBILITY, IF NO E/O HDN
30 If there is no e/o HDN: Select unit of same ABO & Rh blood group as that of neonate. ABO COMPATIBILITY, IF NO E/O HDN Neonate’s Group Compatible Group Optional Group O - A B AB A, B, O NOTE: If mother’s group is same as that of baby, additional major crossmatch with maternal plasma should be done. If there is e/o HDN: Use ABO & Rh compatible unit to both baby’s & mother’s sample. Group is compatible, if Group is optional, if Major Minor With baby’s sample With mother’s sample Major Minor With baby’s sample With mother’s sample NA NA

41 ABO COMPATIBILITY, IF E/O HDN
31 ABO COMPATIBILITY, IF E/O HDN O,A,B AB O B - A Mother’s ABO group Optional Group Compatible Group Neonate’s ABO Group NOTE: If mother’s group is ‘AB’, then baby’s group can not be ‘O’ and if mother’s group is ‘O’, then baby’s group can not be ‘AB’

42 Rh compatibility if e/o HDN:
32 Rh compatibility if e/o HDN: If there is e/o HDN, unit should be Rh compatible to both baby’s & mother’s group i.e. if either of two is Rh negative, then select Rh negative unit. General rules of neonatal transfusion: Don’t use PCV with SAGM solution (additive solution) for neonatal transfusion, as it contains mannitol. Neonatal transfusion is the only contraindication for using PCV with SAGM solution. If you are transfusing blood of optional group (whether there is e/o HDN or not), use semi-PCV (i.e. whole blood from which plasma is removed partially) with low anti-A or anti-B titre. Use fresh blood (<48hrs old preferably) for neonatal transfusion. It should not be more than 5 days old to avoid risk of hyperkalemia. For plasma & platelet transfusion, same group unit as that of baby, should be used. If there is e/o HDN & mother is Rh negative, use unit of Rh negative group.

34 STORAGE OF BLOOD & BLOOD COMPONENTS In Hospital Product Temp Shelf life WB c 24 Hrs. PCV (with SAGM) FFP, CRYO 20 – 60 c 12 Hrs. RDPC, SDPC Room Temp. - Platelets should be kept continuously agitating till transfused to patient. Ideally blood/component units should not be stored in hospital as temp. of the hospital refrigerator is not controlled. Ask the patient’s relatives to bring blood unit from blood bank just before transfusion.

47 ADMINISTRATION OF BLOOD & BLOOD COMPONENTS

48 INTENTIONALLY LEFT BLANK

49 PRE-ADMINISTRATION PRECAUTIONS
35 PRE-ADMINISTRATION PRECAUTIONS Blood bag No. Blood Group of patient Patient’s Name Check For Case Paper Issue Report (Sent by Blood Bank) Cross-match Label (On blood unit) Testing Label (On blood unit) Blood Group of bag Expiry Date Check unit for – Leakage/damage Clot S/o hemolysis S/o contamination

50 36 ADMINISTRATION BT Set – Use BT set for transfusion of all blood products i.e. WB, PCV, FFP, RDPC, SDPC, & Cryoprecipitate. Change BT set every 12 hrs., if patient is requiring ongoing transfusion. Warming – Warming of blood unit is not needed. Infusion of 2-4 units of refrigerated blood over several hours causes no harm. Warming is needed in following conditions – Infants receiving exchange transfusion. Patients receiving rapid transfusion through central venous line. Patients receiving rapid & massive transfusions. Patients with cold – antibodies. (If warming is needed, unit should not be warmed above 370 c. Excessive warming may cause hemolysis in unit & can lead to serious transfusion reaction). Don’t add any medication to unit. You can add only normal saline or 5% albumin to dilute.

51 TIME LIMITS FOR TRANSFUSION
37 TIME LIMITS FOR TRANSFUSION WB / PCV – Within 3-4 hours. ( If room temp. is c At higher room temp., there should be shorter out of refrigerator time). FFP – Within mins. Cryo – Within 5-10 mins. Platelets – Within mins. (RDPC & SDPCs)

52 MONITORING OF PATIENT DURING TRANSFUSION
38 MONITORING OF PATIENT DURING TRANSFUSION - WHEN - Before starting transfusion As soon as transfusion started At 15 mins Every hour On completion 4 hrs. after completion - FOR - General appearance Pulse, B.P., Temp. Respiratory rate Signs of adverse reactions Fever Chills Rash Back pain Respiratory distress s/o anaphylaxis

53 ADVERSE TRANSFUSION REACTIONS
& THEIR MANAGEMENT

54 INTENTIONALLY LEFT BLANK

55 INFECTIOUS ADVERSE TRANSFUSION REACTIONS
39 INFECTIOUS ADVERSE TRANSFUSION REACTIONS Reaction Presentation Cause How to avoid Transfusion transmitted infections During window period, HIV, HBV & HCV infections can not be detected. The test results in blood bank are negative. Technical & interpretational errors Risk of transmission of HIV, HBV & HCV through transfusion can be reduced to nearly zero %, by using NAT tested blood. By using advanced fully automated systems for testing, technical & interpretational errors can be minimized. HIV, HBV, HCV, Malarial parasite, T.pallidum (causative agent of syphilis) are the organisms which can get transmitted through transfusion. Presentation will be as per infection transmitted. Transfusion associated sepsis Fever, chills hypotension, septic shock, DIC Bacterial contamination due to technical errors - Take aseptic precautions during blood collection, product preparation & at the time of transfusion.

56 NON INFECTIOUS ADVERSE TRANSFUSION REACTIONS
40 NON INFECTIOUS ADVERSE TRANSFUSION REACTIONS Reaction Presentation Cause How to avoid Allergic reactions (Very common) Urticaria, pruritis, flushing, rashes Antibody to donor plasma proteins Use PCV instead of WB Use cryoprecipitate instead of FFP, when indicated Non hemolytic febrile transfusion reactions (NHFTR) (Very common) Fever, chills/rigors, headache, vomiting Leukocytes Accumulated cytokines Antibody to donor leukocytes Use leuco-depleted components Anaphylaxis Urticaria, hypotension, bronchospasm, respiratory distress, local edema Antibody to donor plasma proteins Accumulated cytokines Use leuco-depleted components Transfusion associated acute lung injury (TRALI) Respiratory failure, hypotension, fever, bilateral pulmonary edema, hypoxemia - Antibodies to donor leukocytes Use leuco depleted components Platelet refractoriness No rise in platelet count on platelet therapy Leukocytes Allomunisation, HLA antigens Use leuco depleted components

57 NON INFECTIOUS ADVERSE TRANSFUSION REACTIONS
41 NON INFECTIOUS ADVERSE TRANSFUSION REACTIONS Reaction Presentation Cause How to avoid Hemolytic transfusion reaction (Immune hemolysis) Chills, fever, hypotension, back pain, pain along infusion vein, oozing from IV sites, hemoglobinuria, renal failure with oliguria Mismatched blood transfusion - Avoid sample collection errors - Write blood group on requisition form - Pre administration check details - Use of advanced gel technology for crossmatching Hemolytic transfusion reaction (Non immune hemolysis) Chills, fever, hypotension, hemoglobinuria, hemoglobinemia Physical or chemical destruction of RBCs (heating, freezing, adding drugs to blood unit) Avoid warming Don’t add any medications to blood unit Demand blood from Blood bank at the time of transfusion (Don’t store blood units in hospital) Graft Vs host disease (Delayed reaction) Erythroderma, maculopapcular rash, Nausea, vomiting, diarrhea, Jaundice, fever, pancytopenia Donor lymphocytes engraft in recipient & mount attack on host tissue Avoid use of fresh blood (<48 hr old) from blood related donors Irradiate blood unit before transfusion in immunocompromised patients Circulatory overload Dyspnea, orthopnea, cough, tachycardia, hypertension Volume overload -

58 MANAGEMENT OF ADVERSE TRANSFUSION REACTIONS
42 MANAGEMENT OF ADVERSE TRANSFUSION REACTIONS Reaction Presentation Treatment Mild reactions Urticaria, Rashes, Itching Slow the transfusion Give IM antihistaminic If no improvement or worsening then treat as moderately severe reaction Moderately severe reactions Fever, Rigors/chills, Tachycardia, Urticaria, Flushing, Restlessness, Headache, Mild dyspnea Stop transfusion, replace set & keep IV line open with NS. Notify the treating doctor Administer IM antihistaminic, oral antipyretic Give IV steroid & bronchodilator if indicated If improved, can restart transfusion slowly with new blood unit Send blood unit with BT set, post transfusion blood sample collected from vein opposite to infusion site & post transfusion urine sample to blood bank along with reaction report If worsen, treat as severe reaction

59 MANAGEMENT OF ADVERSE TRANSFUSION REACTIONS
43 MANAGEMENT OF ADVERSE TRANSFUSION REACTIONS Reaction Presentation Treatment Severe reaction Fever with rigors, Headache, Dyspnea, Chest pain, Back pain, Pain at infusion site, Respiratory distress, Restlessness, Hypotension (>20%), Tachycardia (>20%), Hemoglobinuria, Unexplained bleeding 1. Stop transfusion, replace set & keep IV line open with NS. 2. Infuse NS to maintain BP. 3. Maintain airway & give high flow O2. 4. Give adrenaline in severe allergic reactions. 5. Give IV steroids & bronchodilators if indicated. 6. Give diuretics to maintain urine output. 7. If e/o DIC, give platelets along with cryoprecipitate or FFP. 8. If bacteremia is suspected, send blood culture & start broad spectrum antibiotics. 9. If renal failure is suspected, maintain fluid balance accurately. 10. Send blood unit with BT set & post transfusion blood & urine sample to blood bank along with reaction report.
