2. INTRODUCTION
Blood transfusion is one of the most
important discoveries of modern medicine
which appeared after Harvey's scientific
explanation about blood circulation (1928)
Its use in surgery has launched great success
after blood incompatibility between
different persons was challenged with the
knowledge of blood GROUPS(A,B,AB,AND
O) (Landsteiner ) & Rh FACTORS( C, D ,E ,c ,d
,e (Levine & Stetsen )
3. INTRODUC.CONT.
Its aim is to restore blood volume and
oxygen carrying capacity.
For the purpose of transfusion, blood is
collected in a bag with 50ml.Of cpd(citrate
phosphate and dextrose or in a bag with
cpd-a(adenine solution) and is stored at
temperature of 40c .
Can be kept for 5 weeks in cpd bag and for
6 weeks in cpd-a bag.
It is grouped using serum with potent
aglutinogens like anti-A anti-B and anti-Rh
and by cross matching.
4. DEFINITION OF BLOOD
TRANSFUSION
Is the process of transferring blood or
blood- based product from one
person into the circulatory system of
another through blood vessels ,long
bones’marrow,sternum,etc.
5. Types of blood transfusion according
to the source
1. Autologous (using patient’s own stored blood)
2. Allogeneic (using stored blood of others)
7. procedures
1. Donation
2. Testing for infections
3. Testing for A B O and Rh groups along with
presence any RBC antibodies
4. Pathogen reduction treatment using riboflavin and
Uv light / gamma irradiation
5. Compatibility testing (recipient’s ABO and Rh
6. Cross-matching
8. Principles(chek list) of blood
transfusion
1) Is one part of pt.’s Rx.
2) Is done when there is no alternative Rx.
3) Compare the benefits and risks
4) Know the aim(goal) of the planned transfusion
5) There should be informed consent of the pt.
6) Record the reason(indication) for transfusion on
the chart
7) Do not use Hgb. as the only criteria
9. PRINCIPLES OF TRANSF. CONT.
8. Be aware of the risks
9. Minimize the reason for transfusion during
surgery
10. The blood should be screened and cross-
matched
11. Avoid the concepts of “universal donors and
universal receptors”
12. The blood should be at body temperature
13. Always start with few drops and increase
progressively
14. Take care of CHF in children, old age and
cardiopathic pts.
15. Monitor closely during and after the transfusion
10. INDICATIONS FOR BLOOD TRANSFUSION
Blood transfusion can be done in:
1. Neonate
2. Children & infants
3. Pregnant
4. Adults
11. Indication for blood transfusion in
neonate
1. Severe unconjugated hyperbilirubinemia
2. Hemolytic diseases
3. Severe pulm. diseases with Hgb. <13gm/dl
4. Severe heart disease with Hgb. <13gm/dl.
5. Acute blood loss with:
Signs of anemia
No signs of anemia but Hgb. <7gm/dl
6. Extensive burn
7. Bleeding disorders (in preop.phase)
8. Intraoperative of major surgery with blood loss.(Cv.
Surgery ,gastrectomies etc.)
12. Indications of blood transfusion in children &
infants
1. IF Hgb.<4gm/dl
2. Hgb.=6gm/dl with life threatening signs such
as:
Hypoxia with cardiac descompansation
Acidosis
Impaired consciousness
Hyperparasitemia
Cerebral malaria with increasing hemolysis
Septicemia
Meningitis
13. Indication for transfusion of blood in pregnants
A. IF < 36 WEEKS:
1. Hgb <5gm/dl
2. Hgb. 5-7gm/dl with :
Signs of cardiac failure
Infections
Malaria
Hx. Of heart disease
B. IF > 36 WEEKS:
1. Hgb. <6gm/dl
2. Hgb. 6-8gm/dl but with other diseases (as
indicated above)
C. ELECTIVE C/S WITH Hx. OF:
1. APH (ante partum hemorrhage)
2. PPH(postpartum hemorrhage)
D. PREVIOUS C/S WITH Hgb.<10gm/dl
14. Indications of blood transfusion in adults
1. Preoperatively in pts. with malignancies,
bleeding disorders and anemia which is likely to
cause hypoxia
2. Acute hemorrhagic shock
3. Extensive burn
4. Intraoperative of major surgeries with significant
blood loss
5. Chronic anemias with hypoxia and Hgb.
<5gm/dl (sickle cell anemia)
6. Septic shock ,Co poisoning ,snake bite with
hemolysis
15. Complications of blood transfusions
1. Transfusion reactions
2. Transmission of diseases
3. Thrombophilebitis
4. Congestive heart failure
5. Disseminated intravascular coagulation(DIC)
with uncontrollable bleeding
6. Adult Resp. Distress Syndrome(ARDS)
7. Citrate intoxication
8. Hyperkalemia(long term stored blood)
9. Air embolism
10. Dilution of clotting factors
16. Blood transfusional reactions
1. Simple pyrexial reaction
2. Allergic reactions to:
Leucocytes & platelets of the donor
Some ingested substances in the blood
of the donor to which the receptor is
sensible
3. Incompatibility reaction
4. Hemolysis
5. Development of antibodies to RBC and plasma
proteins (in hemophilic & pupuric pts. by
repeated transfusions)
17. Transmission of diseases as complication of blood trans
fusion
Can be explained by transmission of:
1. Serum hepatitis(HCv HBv)
