(Blank)
What are the indications for granulocyte transfusions?
A patient with a documented infection, typically gram negative bacteria or fungi
Unresponsive to antimicrobial therapy
What is the minimum amount of platelets in a platelet aphereis?
3.0 times ten to the eleventh power
What are the requirements for leuko-reduced blood components?
Achieved through filtration and collected by apheresis method.
When getting new units in, how many segments do you keep and why
Keep two segments. One for ABO/RH type confirmation and the other to keep in a bag for later testing in cases of transfusion reactions: keep for 7 days after unit expiration date
What is the storage cooler packed with in Red blood cells vs FFP
RBC: wet ice
FFP: dry ice
What is the expiration for thawed FPP?
5 days
What kind of platelet until has the highest platelet yield
Platelet apheresis
What is the criteria for visual inspection of RBC
Discoloration (purple, black, or too dark) could indicate bacterial contamination, segment colors, supernatant, zone of hemolysis
Describe why liquid plasma would be used instead of FFP or cryo
type a liquid plasma used in MTP or on Life flight for patients undergoing life threatening trauma/hemorrhage.
Specifically type A plasma is used and O RBCS because that is what is compatible with the majority of the population.
What information must be on Blood administration tag?
Patinet name, MR number, DOB, BB bracelet number, blood type, patient location, age and gender, provider, until number, product type, donor blood type, unit exp date and time, tech ID, date
What is the expiration for thawed cryo?
4 hours if pooled, 6 hours if unpooled
What blood component is cryo derived from?
FFP
visual inspection for platelets
excessive aggregates, clotting, cloudiness, small white clumps, lipemia or milky, clotting or bacterial contamination
Describe leukoreduction filters
These filters use a combination of barrier filtration (pore sized) and cell adhesion to trap the WBCs
What is the formula for calculating the dosage of the amount of cryo that is required
Desired factor 8 level times patient plasma volume in mL divided by the average units of factor 8 per unit of cryo (80U)
What temperatures should FFP and cryo be thawed and HOW are they thawed?
Placed in waterbath at temperature of 30-37 degrees Celsius
List blood products that can cause GVHD in patients
Whole blood, RBC, plt, granulocytes, NOT FFP or Cryo
visual inspection for plasma
clarity, lipemia, discoloration like grey or milky, inspect when removed from storage to determine if there are cracks or leaks or if it has been thawed and then refreezed, etc
What is the minimum unit volume of FFP
180 mL
Compatibility testing for platelets is not necessary unless how many mL of red blood cells are present
2 mL or greater
What is the minimum amount of platelets in a platelet concentrate?
5.5 times ten to the tenth power
What kinds of patients are at risk for GVHD
Cancer patients, immunocompromised, cellular immunodeficiency, etc, proneitor cell or marrow transplants, HLA compatibility
visual inspection for cryo:
particulate matter, clots, or fibrin strands, leaks or breakage of bag or tubing, signs of degeneration
What can the following types receive plasma from :
A:
B:
AB:
O:
A: A, AB
B:B, AB
AB: AB
O: A, B, AB, O
this is the same for cryo
