Blood transfusions
Indications
- Restore
circulating blood volume
- Replace
clotting factors
- Improve
oxygen carrying capacity of the
blood
Complications
Circulatory overload
Prevent by giving, packed
cells, frusemide, monitoring CVP.
Intervention, stop
transfusion, sit upright, reassure
Disease transmission
- Hepatitis B
- Hepatitis non - A - non - B
- Cytomegalovirus
- Malaria
- Syphilis
- HIV
Prevent by, screening
Pyrogenic reactions
Due to agglutinations following transfusion of antigens,
Prevent by,
- removal of leucocytes and platelets from donor blood
- antipyretics or steroids
Due to bacterial contamination,
S+S, fever
flushing
headache
substernal
pain
D + V
Hypotension
Abdominal and
extremities pain
Prevent by,
- Keeping blood cool
- No pre transfusion warming
- Inspect for gas bubbles and colour change
Intervention,
- Stop
transfusion
- Blood cultures
- Treat
septicaemia
Allergic reactions
S+S
- Flushing
- Itching and
rash
- Urticaria,
(hives)
- Wheezing and
laryngeal oedema
Prevention
- Ask about
allergic history
- Prophylactic
antihistamines in some cases
Intervention
- Stop
transfusion
- Adrenaline to
hand
Haemolytic reactions
Incompatibility causing agglutination and subsequent
haemolysis
Use a blood filter to filter out clots
S + S
- Chilliness fever
- Loin pain
- Feeling of head fullness
- Oppressive feelings in the chest
- Anxiety
- Tachycardia
- Tachypnoea
- Hypotension
- Haemoglobinuria
- Oozing from venepuncture sites
Prevention
Correct identification of blood and patient
Stay with patient for first 15 -30 minutes
Start transfusion very slowly
Intervention
- stop
infusion
- summon
help
- maintain renal perfusion, eg. diuretics
- maintain
circulating volume
- catheter to monitor urine volumes
Haemolytic transfusion reactions may occur one to two
weeks after infusion.
Hyperkalaemia
S+S
- GI
symptoms
- weakness
- parathesia
of extremities
- apprehension
- slow
pulse
- cardiac
arrest
Prevention
Don`t use old blood
Don't abuse packs of blood
New blood for large transfusions
Hypocalaemia
Results from large volumes of citrate.
S+S
- tingling
- muscle cramps
- hyperactive reflexes
- convulsions
- carpopedal spasms
- laryngeal spasms
Haemosiderosis
Iron overload
Air embolism
S+S
chest pain
cough
dysponea
Cold blood
Rapid infusion of cold blood can cause cardiac arrest.
