Overview
• It is a procedure in which a patient
receives a blood product through an
intravenous line.
• It is the introduction of blood
components into the venous
circulation.
• Process of transferring blood-based
products from one person into the
circulatory system of another.

4.
BLOOD GROUPS
4

5.
Types of blood groups
• There are more than 20 genetically
determined blood group systems known today
• The AB0 and Rhesus (Rh) systems are the
most important ones used for blood
transfusions.
5

6.
ABO blood grouping system
• There are
four different
kinds of blood
types:
• A, B, AB or O
(null).
6

7.
Blood Types
• Each person has one of the following
blood types: A, B, AB, or O.
• O can be given to anyone but can only
receive O, so called as Universal Donor.
• AB can receive any type but can only be
given to AB, so called as Universal
Recipients.
• Also, every person's blood is either
Rh-positive or Rh-negative.

8.
The ABO blood groups
• The table shows the four ABO phenotypes ("blood
groups") present in the human population and the genotypes
that give rise to them.

Blood
Group
Antigens
on RBCs
Antibodies in Serum Genotypes
A A Anti-B AA or AO
B B Anti-A BB or BO
AB A and B Neither AB
O Neither Anti-A and anti-B OO

9.
The Rhesus (Rh) System
• Well, there's another antigen to be
considered always - the Rh antigen.
• Some of us have it, some of us don't have.
• If it is present, then blood is RhD positive,
if not it's RhD negative.
• So, for example, some people in group A
will have it, and will therefore be classed
as A+ (or A positive).
• While the ones that don't, are A- (or A
negative).
• And so it goes for groups B, AB and O.

10.
• According to above blood grouping systems, you
can belong to either of following 8 blood groups:

2Deg C
• Shelf Life of CPD Blood - 3 wks
• R.B.C’s - 3 wks
• W.B.C – Rapidly Destroyed
• Platelets – Reduced in 24 hrs

16.
Blood Donation
• 475ml Blood + 63ml Anticoagulant
• Post – Transfusion Purpura
• Red cells + Optimal Additive solution
• SAGM
• Expiry date = 35 days
• One unit of blood raises the haemoglobin
concentration by approximately 1g/100 ml

17.
Indications
• Acute blood loss – Due to Trauma.
• Chronic Anemia.
• Major Operative procedures
• As a Prophylactic measure to
Surgery
• Severe Burns
• Blood Dyscariasis

18.
Transfusion Trigger
• The decision to transfuse any patient for a
given indication must balance the risks of not
transfusing.
• RBC transfusion not indicated when Hb>10g/dl
• Transfuse Criteria
- < 6g/dl - Benefit from Transfusion
- 6 - 8g/dl - Unlikely to benefit – absence of
bleeding
- > 8g/d l - Not indicated

19.
IMMEDIATE
COMPLICATIONS
Immunological
- Febrile / non
haemolytic
- Allergic / Anaphylaxis
- Haemolytic TR
- TRALI
Non- Immunological
- Congestive Cardiac Failure
- Infection
- Air Embolism
- Thrombophlebitis
- TACO

20.
Febrile Non Haemolytic Transfusion
Reaction
• Defined to be a rise in temperature
of 1 °C or more and >=38 °C,
within few hours of transfusion with
Chills & Rigors.
• Due to cytokines in the blood itself
and/or pyrogens in the transfusion
apparatus.

21.
Allergic / Urticarial Transfusion
Reaction
• Most common usually due to allergies
to specific proteins in the donor’s
plasma.
• Mild – Trt – Steroids & Antihistamines.
• For severe (anaphylaxis), unit is
discarded. New washed RBC’s and
platelets are used.

22.
Acute Haemolytic Reaction
• Transfusion of an incompatible blood
component. { ABO incompatibility }
• A disaster, almost always preventable.
• Most often due to ABO mismatch due
to a clerical error (i.e., the wrong blood
and/or the wrong recipient).
• Intravascular destruction – ARF & DIC

23.
Acute Haemolytic Reaction
• Features - fever, hypotension, NV,
tachycardia, dyspnea, chest or
back pain, flushing & anxiety
• Post-op site: diffuse bleeding
• Trt - Fluids, diuresis and
transfusion support for bleeding

24.
Transfusion Related Acute Lung Injury
[ TRALI ]
• Due to donor plasma containing an antibody,
usually against the patient's HLA or leukocyte
specific antigens.
• The donor antibodies cause these neutrophils
to release toxic products and thus produce
ARDS.
• Features - Dyspnea, hypotension and fever
typically begin 30 minutes to 6 hours after
transfusion
• chest x-ray shows diffuse non-specific
infiltrates , “white out”

25.
Infections
• Bacterial infection – Due to faulty
storage.
• Serum hepatitis.
• HIV Infection
• Malaria transmission
• Viral – EBV / CMV
• Syphilis / Yersinia

26.
Transfusion Associated Cardiac Overload
[ TACO ]
• 1% of Transfusions are Complicated by
TACO.
• Features – Dyspnoea, hypertension,
crepitations & low O2 Sat.
• Risk of volume overload / respiratory
distress especially in small / elderly pt.
• Largely avoidable by careful attention to
fluid balance.

27.
Delayed Complications
• Delayed Haemolytic TR
• Post – Transfusion Purpura
• Transfusion related graft versus host
disease { TGVH }
• Immunosuppression
• Iron overload – Multi transfused
recipients

28.
Delayed Haemolytic Transfusion Reaction
• Previously sensitized to an antigen
through transfusion or pregnancy.
• Can result in symptomatic or
asymptomatic hemolysis several days
(2-10 days) after a subsequent
transfusion.
• These present with flu-like symptoms,
recurrent anemia and jaundice.

29.
Transfusion-associated graft-versus-host
disease (TA-GVHD)
• Donor T-cells attack host tissues.
• Symptoms occur within 1-4 weeks.
• Rare but always fatal.
• Features – Pancytopenia / Rash / Liver
dysfunction.
• Difficult to treat.
Skin manifestation of GVHD
Generalized swelling, erythroderma and bullous
formation

30.
Massive Blood Transfusion
• Replacement Or Transfusion of blood
= pt’s blood volume within 24 hours [ In
normal adult – 10 units or 5-6 L ]
OR
• Single transfusion > 2500ml
continuously

31.
MBT - Complications
• Coagulopathy
• Hyperkalemia / Hypocalcaemia
• Citrate toxicity
• Hypothermia
• Infections
• Incompatibility & Transfusion reactions
• ARDS / DIC

32.
