25
after taking blood from cat replace
amount drawn with IV fluids
26
can collect blood in
plastic bag or glass bottle
27
advantages to collecting blood in plastic bag(4)
non-breakable, no vacuum, no activation factors, component separation easier
28
disadvantages to collection blood in plastic bag(2)
migration of plastic into blood, slow collection
29
advantages of collection blood in glass bottle (2)
speedy collection, no glass migrate into blood
30
disadvantage of blood collection into glass bottle (4)
cell trauma, breakable, glass activates coagulation factors, difficult to separates
31
shelf life of heparin
24hrs
32
heparin function
anticoagulant
33
3.8% Na Citrate shelf life
24hrs
34
3.8% Na Citrate function
anticoagulant
35
acid citrate dextrose (ACD) shelf life
21 days
36
Acid citrate dextrose shelf life
anticoagulant and preservative
37
Citrate phosphate dextrose (CPD) shelf life
21 days up to 23 days
38
Citrate phosphate dextrose function
anticoagulant and preservative
39
Citrate phosphate dextrose with adenine function
anticoagulant and preservative
40
Citrate phosphate dextrose with adenine shelf life
35 days
41
whole blood good for (2)
oxygen increasing and volume expansion
42
indications for giving whole blood
hypovolemic anemia
43
fresh whole blood (2)
whole blood used within 6 hours of collection, has platelets and clotting factors
44
Packed RBCs indication
anemic normovolemic
45
giving packed RBC instead of whole blood does what
decreases chances of circulatory overload
46
Fresh Frozen Plasma method to making
whole blood spun and separated within 6 hours and frozen
47
fresh frozen plasma expires
in 1 year
48
Fresh frozen plasma contains
coag factors and plasma protein
49
indication for using fresh frozen plasma(2)
bleeding disorders, give passive immunity
50
Stored plasma
clotting factors not as good
51
Only difference from stored plasma
separated after 6 hours
52
Method to make platelet rich plasma
spin at room temp at 2250 rpms for 4 minutes
53
temp to keep platelet rich plasma
room temp, never refrigerate
54
platelet rich plasma expires in
72 hours
55
indication of platelet rich plasma
thrombocytopenia
56
disadvantage of platelet rich plasma (2)
repeat transfusion due to short half life, increase chances reactions
57
indication cryopercipitate
hemophilia A, and VWD
58
best test for compatibility
crossmatch
59
anticoagulant used for the crossmatch
EDTA
60
for crossmatch, centrifuge samples at
3400 rpms for 1 minutes
61
after first centrifuge for crossmatch
remove and retain plasma
62
wash red cells with saline water to
remove any non-erythrocytic antigens
63
to make cell suspension, mix
02mls blood with .98 mld saline
64
Major cross match
2 drops donor red cell suspension, 2 drops recipient plasma
65
minor cross match
2 drops donor plasma 2 drops recipient red cell suspension
66
control
2 drops donor cell suspension, 2 drops donor plasma
67
incubate crossmatch for
30 minutes at room temp
68
to check for hemolysis during crossmatch fill
blue crit tube
69
1 endpoint observations for crossmatch
hemolysis, agglutination
70
technique to blood transfusion (4)
catheter, filter blood, warm, rate of admin
71
can transfuse blood 3 ways
IV, IO, IP
72
filter blood with
hemonate, admin set with filter
73
rate of admin when start blood transfusion
.11 mls/3/minute for first 15 minutes to observe transfusion reaction
74
indication for plasma transfusion (3)
hypoprteinemic, vital ds, warfarin tox
75
transfusion reactions, 2 types
nonimmunologic, immunologic
76
reasons for nonimmunologic reaction (5)
sepsis, dz transmission, allergic reaction to foreign protein, circulatory overload, hypothermia (arrythmias)
77
types immunologic reactions
immediate, delayed
78
immediate hypersensitivity usually requires
2nd transfusions
79
immediate hypersensitivity signs
salivation, V/D, dyspnea, death
80
delayed hypersensitivity shows
days to weeks after expression
81
delayed hypersensitivity signs
decreased PCV, Hburia, hemolysis over time
82
Oxyglobin is
bovine hemoglobin molecule
83
Oxyglobin shelf life
2 years at room temp
84
common use of oxyglobin
use at first response to buy time, no reaction
85
oxyglobin turns
MM brown
