Introduction to Blood Bank Rotation What is Transfusion
Introduction to Blood Bank Rotation
What is Transfusion Medicine? TM is the practice of laboratory and clinical medicine concerned with all aspects of blood transfusion (scientific basis, selection, recruitment of blood donors, utilization and quality control, preparation of blood componenets, pretransfusion testing, transfusion of components, adverse effects), autoimmunity, transplantation, histocomatibility, therapeutic apheresis, blood substitutes, management of aspects of blood services (regulatory). TM needs a strong foundation in laboratory medicine and clinical medicine.
Scope of TM is broad? • • Immunohematology Hemostasis HLA Blood collection operations Apheresis Stem cell collection Cellular therapies/cell processing Tissue services
How to maximize your time on the blood bank? • Active engagement in TM! – Question and answer during didactic teaching session – Take notes! Especially on facts unfamiliar to you! – Use clinical scenario to spur additional content reading – Identify gaps in knowledge base and request specific lectures/didactic session
What Do I Need To Know? • The Serologic work ups, transfusion reactions • The Pager • The Platelets • The Patients • The Project
What Do I Need To Know? • The Paperwork • The Pager • The Platelets • Patients • Apheresis • ECP • RBC exchange • Benchwork: Please organize with attending and lead staff • ARC rotation: Please arrange rotation at Nashville ARC with Dr. Meena-Leist (Young) in second month of rotation through BB • The Project
1. Pick up paperwork in AM
ABO type/Antibody Screen • Please understand the work-up. If you don’t, please know that you are encouraged to talk to staff. • Antibody screen looks for alloantibodies other than ABO that can cause hemolysis – involves adding patient plasma to two or three O- test cells that are chosen to represent all clinically significant antigens – any positive screen must be worked-up with antibody panel to identify responsible antibody
Antibody Panel • Similar to antibody screen except involves usually 10 different test cells – antigens on negative test cells are not responsible for positive screen – identify alloantibody present by process of elimination
DAT • Positive DAT means something is coating the patient’s red blood cells – That may target this cell for destruction –check Hgb/Hct trend, LDH, indirect (or total) bilirubin, haptoglobin, hemoglobinuria, reticulocyte count, and peripheral blood smear findings – check clinical status of patient –Please do not come to rounds without looking these up. Please do not state in your note only the results of the test without any guidance
Transfusion Reactions • Paperwork appears after the resident on call has been notified (usually the next day) • Look up clinical history and appropriate labs – which product is implicated? how much volume? – changes in vital signs? Are the changes unique to the transfusion? – changes in Hgb/Hct, LDH, bilirubin, haptoglobin, etc. – how was the patient managed by clinical team (did they give Benadryl or Tylenol, or subsequent transfusions)? – how is the patient currently doing?
Transfusion Reactions • usually workup is underway/completed by the time resident is paged • workup includes: – stop the transfusion! – paperwork & bag check for clerical errors – check blood for hemolysis (visually) for hemoglobin –perform DAT (and compare to pretransfusion sample) – send bag and blood sample for culture if indicated
AHTR-clinical evaluation
Transfusion Reactions Hemolysis ? Acute Intravascular lysis Non-immune • Heating • Solution added to RBCs Delayed Extravascular lysis Fever • FNHTR • Bacterial No Fever contamination • TRALI • Anaphylactic • TA-Gv. HD • Medicated FNHTR • Urticarial • Hypotensive • Bacterial • Circulatory overload
What should you ask the tech/M. D. ? • Is there hemoglobinemia? – Compare pre- and post-transfusion spun plasma samples (detect lysis of 5 -10 ml) • Was the clerical check negative? – Did the patient get the right blood? • Is the DAT-positive? – Compare pre- and post-tx DATs
What should you be asking yourself? • Is it a hemolytic reaction ? ? !!
Additional lab work • Repeat ABO/Rh, Ab screen, crossmatch • Urinalysis for hemoglobinuria • Coag studies if indicated • Review prior to approving next transfusion
Clinical management 1. STOP TRANSFUSION keep line open 2. Monitor vital signs, urine output 3. Evidence of a severe reaction? • AHTR, septic shock, anaphylaxis 4. Perform nursing clerical check 5. Return product to BB with new samples
Clinical management 6. Hypotension – Saline, Dopamine (1 mg/kg/hr) 7. Renal failure – Monitor urine output: keep >100 ml/hr X 24 hr – Monitor BUN, crt, lytes – Treat hypotension to prevent renal ischemia – Furosemide (20 -100 mg/12 hrs) – Dialysis
Clinical management 8. DIC – Monitor PT, PTT, fibrinogen, FSP, platelet ct – Heparin 40 IU/kg loading, 5 -6000 IU/12 hr – Transfuse as needed (FFP, plt)
Summary Transfusion Reactions • When you hear “transfusion reaction” assume it is hemolytic until disproved • If there is evidence of hemolysis, make sure to call the Attending • If hemoglobinemia, clerical check and DAT are all negative, significant hemolysis is unlikely; think through other etiologies • Often, the clinicians wants to know if they can give more transfusions…answer accordingly
Biovigilance paperwork
What Do I Need To Know? • The Paperwork • The Pager • The Platelets • The Patients • The Project
Pager Responsibility • Contact the blood bank attending with any issue about which you are unsure • Contact the attending about any mistransfusion, wrong blood in tube, anaphylactic/serious reactions, serious patient issues which if left not taken care of will result in morbidity or mortality
Ways to present to your attending on-call in general • When you call the attending make sure you have a one-liner about what is going on • Know the age, gender, race, diagnosis, and the problem • Have all ducks in a row - know as much information as possible (labs, etc. ) This means calling not only the techs but also the clinicians prior to calling TMP attending. • Have a plan of your own if possible(read a little)
Follow-up and Continuity • Critical as physicians • Check out to the TM day team if you were on call • Call me if there any issues overnight • During the day find out what happened to your patient. Do not wait a week to follow-up.
Paperwork/case handoff between residents • At the conclusion of the day and rotation it is not uncommon to have pending cases still being evaluated (i. e. cultures for transfusion reactions, additional immunohematology panels, etc…) • These cases must be discussed and properly handed off to the incoming resident • Keeping track of the paperwork is key! This is an FDA requirement!!!!
Handoff Duties • Inform weekend resident and the next month’s resident of any patients with ongoing product needs or other issues they will likely encounter • Give them any paperwork they might need in managing those patients
What Do I Need To Know? • The Paperwork • The Pager • The Platelets, product usages/product manipulations • The Patients • The Project
Platelets • Each day the blood bank staff will provide a list of all ABO (out of group) and Rh (incompatible) platelet transfusions – Review clinical history to determine impact of ABO out of group transfusions • Passive mediated hemolytic transfusion reaction evaluation – Rh- see Rh. IG evaluation
Improper Product Usage • Multiple Platelet Units – ideally a post-transfusion platelet count should be checked before administering additional platelet products • ensures patient is benefitting from transfusion • avoids alloantibody formation and/or potential transfusion reactions associated with a product that might not be of benefit to the patient • clinicians typically receptive to this request – exceptions DO EXIST: use clinical judgment
Platelet Refractoriness • progressive diminution in platelet increase following transfusion • arises due to alloimmunization in patients who have required multiple transfusions, most often associated with chemotherapy • other etiologies: systemic infection, splenomegaly, drugs, platelet consumption (DIC)
American Red Cross • Phone number: 615 -346 -7935 • Discuss platelet needs with clinicians – what are their goals? – when are platelets needed (generally ASAP)? – how many transfusions are anticipated daily? • Stay ahead of the game! – ARC needs notification and bloodwork by noon in order to get platelets for the next day – be proactive on Fridays in preparation for weekend transfusion needs
Apheresis Platelets • contain at least 3 x 1011 platelets • minimizes alloimmunization since only one donor exposure • expected platelet increase: ~30, 000/µL – consider refractoriness when increments progressively decrease – must prove refractoriness with two post-transfusion platelet counts obtained 15 minutes to 1 hour posttransfusion – if refractory to cross-matched platelets or attempt HLA-matched platelets
Star. Panel Transfusion History 1. “Labs” 2. “Other. Heme” 3. “Hem/BBprod”
Improper Product Usage • Washed Red Blood Cells – indications: • prevention of allergic reactions in Ig. A-deficient recipients • May also be indicated in severe allergic reactions • transfusion to neonates from a parent or from ABO incompatible plasma or to reduce K+ – NOT indications: • prevention of hemolytic transfusion reactions • prevention of alloimmunization • prevention of CMV transmission

SCT/Photopheresis • Stem cells are collected from peripheral blood from patients as well donors after appropriate mobilization of these cells from the bone marrow. • The collection is by apheresis • Patients who are suffering from chronic GVHD or solid organ transplant rejection (more rare) occasionally receive extra corporeal photopheresis. This involves treating buffy coat with 6 -MOP under UV to effect immunomodulations. • Responsibilities include – See each patient – Establish working relationship with nurses • Write note (template available) on the day of the procedure (M-F) • Address any mild adverse reactions
Stem cell Collection • For each patient, know – Auto or Allo – Diagnosis – CBC – Clinical status – Mobilization regimen – Goal of collection – Any recent lab abnormalities? – Predicted collection success
Photopheresis • For each patient, know – Clinical status (how stable are they? ) – Reason for photopheresis • What are their clinical manifestations – Number of procedures thus far – CBC – Any recent lab abnormalities
Adverse reactions with SCT and Photopheresis • Any serious reaction (anaphylaxis, cardiac symptoms, seizure) page BTU and TM attending on call, in that order. • Patients have PRN orders for nausea and pain • Hypocalcemia – Mild, tums or IV calcium (adults 4 g in 100 cc NS IV over procedure; kids 200 mg/per L processed • Hypotension – Mild—slow down procedure, give 250 cc NS bolus – Not mild, trendelenburg, – Not responsive—have NP call. If not resolved, call BTU attending on service

What Do I Need To Know? • The Paperwork • The Pager • The Platelets • The Patients • The Project
The Project • Each resident gives a 30 minute presentation typically at 10 am at the end of the month • Topics are chosen by the attending to reflect ongoing issues in transfusion medicine • Often useful to service in guiding or exploring new policies
Interesting Case Conference • Each resident gives a 20 minute brief case presentations typically before rounds • Cases should be a balance between those occurring during each attending on service • Please present the relevant facts, your plan/assessment and a few slides of didactics/data
Daily Pages/Curbsides • How to document the onslaught of issues… – If the clinical matter is short and sweet, simply answer the question and document it in your resident call log book, notes, or whatever mechanism you have in place to verify transmission of information – If you have to look something up, speak to a medical technologist, confer with an attending, or a combination of the above, then you have to place a clinical communication in the chart!
