25
when should inspection of blood components occur?
``` before shipping from donor center to transfusion service upon receipt in the transfusion service at time of allocating to patient at time of sign-out at bedside before transfusion ```
26
component inspection for red blood cells
hemolysis in bag and segments | particulate matter and clots
27
component inspection for platelets
swirling | clots
28
component inspection for plasma and cryo
fibrin strands
29
standard blood filter
170 to 260 microns
30
microaggregate filter
20-40 microns
31
contraindication for microaggregate filter
platelets and granulocytes
32
contraindication for leukocyte reduction filter
granulocyte components
33
purpose of standard blood filter
remove small blood clots and particles potentially harmful to recipient
34
function of microaggregate filter
removes smaller clots and particles including platelets and granulocytes; originally designed to remove leukocytes
35
current typical use for microaggregate filter
shed autologous blood collected during surgery or during massive transfusion
36
function of leukocyte reduction filter
reduces number of leukocytes in red cells and platelets to less than 5x10^6 cells per unit
37
is pre-storage or bedside filtration preferred in leukocyte reduction?
pre-storage
38
review during final issue of blood to prevent transfusion mishap
``` 2 recipient identifiers recipient Abo/Rh donor unique unit number compatibility testing results donor Abo/Rh special transfusion requirements expiration date and time ```
39
documentation at issue of blood components
visual inspection time and date of issue technologist who issued component name of person picking up component
40
RBC infusion rate
150-300 ml/hr
41
plasma infusion rate
200-300 ml/hr
42
platelet transfusion rate
200-300 ml/hr
43
cryo transfusion rate
as rapidly as tolerated by patient
44
granulocyte transfusion rate
75-100 ml/hr
45
assessment of recipient includes:
baseline physical assessment (vitals, temp, pulse, BP) | assessment for signs and symptoms before transfusion
46
infusion rate of any blood product for first 15 minutes
2 ml/min
47
when are vital signs taken during transfusion?
before and after
48
OR and trauma infusion rate
as fast as 600-1500 ml/min
49
what may be noted with rapid transfusions?
hypothermia, hypocalcemia
50
patient unit tag/label must indicate:
2 recipient identifiers donor unique unit number compatibility testing result attached securely to unit
51
final records check of blood components must include:
``` 2 recipient identifiers recipient ABO/Rh donor unique number compatibility testing results donor ABO/RH date and time of issue special transfusion requirements expiration date and time ```
52
what must be in 100% agreement prior to issue of blood components?
identifying information initial request recipient's records all blood components
53
actions performed by transfusion service technologist when issuing blood components in urgent situations
issue uncrossmatched blood, indicating on tag that crossmatch incomplete start compatibility testing as soon as sample is received contact medical director if uncrossmatched units are found to be incompatible
54
emergency release blood if recipient's blood type is unknown
group O Rh negative to females of childbearing age males and females over age 50 may receive Rh positive
55
definition of massive transfusion
8-10 RBCs to adult patient within 24 hours
56
acute massive transfusion definition
4-5 RBC units to adult patient within 1 hour
57
massive transfusion to infant definition
exchange transfusion
58
stop serological crossmatching blood after adult patient has received ___ during massive transfusion
>10 units of RBC within 24 hours
59
switching from group O AS-1, AS-3, AS-5 RBC units to ABO identical units can be safely done because?
minimal residual plasma in group O AS units
60
minimal residual plasma is group O AS units lowers risk of...
passive anti-A and anti-B transmission
61
what can be given if Rh-negative woman of childbearing age receives Rh-positive blood components to prevent anti-D from forming?
Rh IG prophylaxis
62
requirements for return/reissue of blood components
primary container not tampered/entered appropriate temp maintained at all times one or more retention segments intact written documentation states blood component passed inspection and is ready to be returned to inventory
63
what happens to red cells if transfused with Ringer's Lactate?
red cells clump due to ionized calcium chelating citrate
64
medications containing calcium or gluconate solution do what if transfused with red cells?
neutralize CPD and cause blood to clot
65
hypertonic solutions cause what to happen if transfused with red cells?
red cells lyse and break
66
dextrose solutions cause what if transfused with red cells?
hemolyze, swell and clot
