Blood Transfusion Flashcards
what is autologous
own blood
what is homologous
standard donation
what is Rh factor positive
d antigen present
what is rh negative
no d antigen
what can expose you to d antigens
fetomaternal
blood transfusion of rh+ blood
what is RhoGAM
given to prevent hemolytic anemia
people who are Rh- can get Rh positive blood t/f
f
what is crossmatching
Recipient serum tested against donor cells
Determines if recipient has any pre-formed
antibodies against antigens in the donor’s cells
See agglutination & clumping if incompatible
how long is crossmatching good for
3 days bc new antibodies might form
what can be transfused
whole blood
Packed RBCs
Platelets
Fresh Frozen Plasma
Cryoprecipitate
White Blood Cells (Granulocytes)
Albumin (not treated as a blood product)
how many ml of whole blood
500
how many ml pf packed rbcs
250
packed rbcs given when hgb is
<6-7
range of when platelets given
10,000-20,000
what can cause sepsis if given at room temp
platelets
how long are platelets transfused for
15-30 min
what do you give for platelet rigors
benadryl and tylenol
what does freezing plasma do
preserve clotting factors
how much of frozen plasma is given
200-250 ml
what rate does fresh frozen plasmatransfuse at
10 mL/min
cryoprecipitate is a rich source of
fibrinogen
where is cryoprecipitate derived from
plasma
what factors are in cryoprecipitate
willlebrand factor, factor 8 and 13
when is cryoprecipitate given
fibrinogen <0.8-1 g/L
DIC
how fast is cryoprecipitate given
bolus 3-5 min
what has a potential for severe reaction
wbcs
how fast are wbcs given
45 min-2 hrs
albumin is a plasma ….
expander
when is albumin given
low volume
liver failure
burns
what rate is albumin given at
1-4 ml/min
what are you monitoring for with albumin
heart failure
what to assess before blood products given
previous reactions
cardiac and resp, urine output, skin
vs assessment after getting blood
iv access- 18-20 gauge
what do we premedicate with
benadryl and tlyenol
how many nurses to give blood
2
devoted IV line primed with…
NS only
how long do we stay wiht our pt
1st 15 min and vs @ 15 min
vs should be done how often after blood is given
q1 hr
transfusion reactions
acute hemolytic reaction
febrile reaction
allergic reaction
Fluid/Circulatory overload
Bacterial contamination Sepsis/Septic
shock
TRALI
TA-GVHD
Acute pain transfusion reaction (APTR)
how much does hbg increased after given
1 gram/unit given
what is acute hemolytic reaction
Immediate onset typically
Life threatening
Donor and recipient incompatibility- Rh
s/s of acute hemolytic reaction
Apprehension, HA, tachycardia, tachypnea,
hypotension
low back pain/CP, hemoglobinuria, chills, fever
Can lead to acute kidney injury, DIC & shock
Delayed= jaundice (milder form)
IMPENDING DOOM
treatment of acute hemolytic reaction
stop transfusion
new iv tubing and NS
febrile reaction
most common
onset within firsdt 2 hrs
s/s of febrile reaction
fever
chills
tachycardia
hypotension
fluhing
HA
anxiety
what can minimize febrile reaction
leukocyte filter
onset of mild allergic reaction to blood
during - 24 hrs
mild allergic reaction s/s
itching
flusing
hives
anaphylactic reaction to blood s/s
immediate onset
wheezing
dyspnea
chest tightness
cyanosis
decreased bp- anaphylactic shock
how to treat anyphylatic shock
o2/maintain airway
epinephrine
ns IV fluids- vasopressin if needed
steroids and antihistamines
circulatory fluid overload
Cough, SOB, crackles, JVD, hypertension
Slow the transfusion rate
Elevate HOB if symptomatic
Notify MD to order diuretic
sepsis
uncommon
Rapid onset chills, fever, dyspnea,
hypotension
Stop transfusion
Notify MD to order blood cultures and antibiotics
what is transfusion related acute lung injury
Non- cardiogenic pulmonary edema (ARDS)
Donor cells damage pulmonary
endothelium
Sudden onset within 6 hours of
transfusion
Hypoxia
Pulmonary infiltrates on X-Ray
Transfusion-associated graft-vs-host
disease (TA-GVHD)
Rare, high mortality rate
Immunosuppressed patients
Acute pain transfusion reaction (APTR)
Uncommon, recently identified
Patho unclear
Does not appear to be life-threatening
if reaction occurs…return blood bag and tubing to… and document on
blood bank
transfusion reaction form
old blood can cause k+ to
increase
calcium levels can … if many units of blood are administered
decrease
compensate for loses with
Procrit (EPO)- erythropoeitin
IV iron sucrose (venofer)
Oral iron
