Components of Blood
• Formed elements-Cells
– Erythrocytes (RBCs)
– Leukocytes (WBCs)
– Thrombocytes (platelets)
• Plasma
– 90% water
– 10% solutes
– Proteins, clotting factors
1
What can we give?
• Whole blood
• Packed RBC (PRBC)
• Platelets
• Fresh Frozen Plasma
(FFP)
• Granulocytes
• Cryoprecipitate
• Factor VIII
• Albumin
What are expected
outcomes?
2
Antigens
• Definition: a substance capable of
stimulating the production of an antibody
and then reacting with that antibody in a
specific way
• Inherited
• Found on red cells
• ABO, Rh (D antigen)
3
Antibodies
• Definition: protein produced by the
immune system that destroys or inactivates
a particular antigen
• Produced as a result of antigenic reactions
• Found in plasma
4
Agglutination
• Caused by reaction between antigens and
antibodies
• Type & screen
• Type & cross

Ways to Give & Receive
• Autologous
• Intraoperative
• Postoperative
• Homologous
–Volunteer
–Designated donation
7
Blood Components (Phillips, ch. 11)
• Key points
–All blood MUST be infused within 4 hours
–Catheter size: 22- to 14-gauge with 20- to
18-gauge appropriate for general
populations
–Must use filter specific for blood
–Administration set changed with every
unit
8
Blood Components: Whole blood
• volume — 500 cc (approx.)
• Rarely used
• Must be ABO compatible
• Acute massive blood loss >25%
• Raises Hgb by 1 g/dL
• Raises Hct by 3%
9
Blood Components (Packed Red Cells)
• must be ABO compatible
• Volume — 250 – 300 mL (approx.)
• Use for chronic symptomatic anemia
• NOT used for volume expansion
• Raises Hgb 1 g/dL and Hct 3%
• Use only 0.9% sodium chloride as primer
• Use 170 micron filter
• Administer over4 hours (usually 2 hours)
10
Leukocyte Reduced RBCs
• Filter: leukocyte filter
• Need physician’s order
• Filter 99% of WBCs that cause febrile reactions
11
Blood Components: platelets
• Use: control bleeding in platelet deficiency
• Use in thrombocytopenia
• Administration: 1 unit (30 – 50 mL) over 5
– 10 min.
• ABO compatibility not required but
preferred.
• 1 unit raises platelet count 5 – 10,000
• Administer 6-8 units/time
– Apheresis = single donor
12
Plasma Derivatives: FFP
• Plasma
– Liquid portion of blood; does not contain RBCs
• Fresh frozen plasma
– Prepared from whole blood separating and
freezing plasma within 8 hours of collection
– FFP may be stored up to 1 year
– Does not provide platelets
– Typical volume is 200 – 250 mL
• Use: procoagulant deficiencies, DIC, massive
transfusions in trauma
13
Plasma Derivatives: Albumin
• plasma protein that supplies 80% of
plasma’s osmotic activity
• Does not transmit viral disease because of
extended heating process
• Available as 5% or 25% solution
• Glass bottle: administration set w/air vent.
14
Alternatives to Blood Transfusions
• Augmentation of volume with colloid
solutions
• Autologous cell salvage
• RBC substitutes
• Modified hemoglobin or hemoglobin-
based oxygen carriers
• Perfluorocarbons (PFCs)
• Erythropoietic stimulating agents (ESAs)
• White cell growth factors
• Hematinics
15
Administration of Blood Components
• Key points
–Assessment
–Preparing for transfusion
–Obtaining blood from lab
–Checking unit with another nurse
–Initiation of transfusion
–Monitoring
–Disposal
16
Assessment of Patient Prior to
Initiation of Blood Transfusion
• Check hospital P&P
• Consent in chart
• Review any parameters set by physician
• Vital sign base line
• Assessment of lungs and kidneys
• Laboratory values
• Patient history of transfusions
17
Preparation for Transfusion
• Initiate IV with appropriate catheter; in most
situations, 20- to 18-gauge
• If IV infusing, check patency and cannula size
–Saline lock: flush to check patency
• Start primer of 0.9% sodium chloride with Y
administration set
• Y set has 170 micron filter
18
Obtain Blood Component from Lab
• Pick up only one unit from lab at a time!
• Clerical errors most common transfusion
complication
• Sign for blood – checking
– Name, identification number of patient
– Transfusion donor number
– Expiration date of component
– ABO and Rh compatibility
19
Preparation for Administration
• Check with another licensed person
compatibility information
– Name, identification number of patient
– “paper to armband” then
• “paper to blood bag”
– Transfusion donor number
– Expiration date of component
– ABO and Rh compatibility
• Obtain set of vitals prior to initiation
20
Administration
• Wear gloves to hang blood
• Spike bag and hang
• Turn off sodium chloride
• slowly begin infusion
• Stay with patient a minimum of 15 minutes
21
Rate of Infusion
 Dr. order?
 Age of patient
 Purpose of infusion
 Other medical conditions (CHF)
 Current IV rate
 “slow” rate for 1st 15 min.
 Craven: 10 gtts/min (60 ml/hr)
 Phillips: 2 ml/min (120 ml/hr)
 Berman et al Skills book: 20 gtts/min (120 mL/hr)
 Must be infused w/in 4 hours
22
Monitoring of Transfusion
• Check vitals per hospital P&P
–Reflected on blood transfusion slip
• Assess kidneys and lungs throughout
• Observe for signs and symptoms of
transfusion reactions
23
Transfusion reactions
Immune
• Acute hemolytic
• Delayed hemolytic
• Nonhemolytic
febrile
• Allergic
Non-Immune
• Circulatory overload
• Hyperkalemia
• Hypothermia
• Citrate toxicity
• Bacterial contamination
• Coagulation imbalances
• Transmission of infectious
disease
24
Transfusion Reactions
• Immediate
–Hemolytic transfusion reactions
–Non-hemolytic transfusion reactions
• Febrile
• Allergic
25
Hemolytic transfusion reactions
• Wrong blood to
wrong patient
• Occurs within 5 – 15
min. of initiation of
transfusion
• Death
• DIC
CMs
• Fever (w/ or w/out
chills
• Hypotension
• Pain: lumbar, flank,
chest
• Tachycardia
• Tachypnea
• Hemoglobinuria
• See Table 11-8
26
Suspected Hemolytic Reaction?
• Stop transfusion
• Do NOT flush w/NS flush bag
• Disconnect blood tubing, then flush.
• Prepare to treat shock
• Follow hospital guidelines:
– Notify MD
– Save blood bag
– Call lab
– Blood sample
– Urine sample
27
Febrile reactions
• Cause: reaction to antibodies in blood in
reaction to leukocytes
• Signs and symptoms : fever, chills, HA
• Treatment: stop blood, notify RN, notify
physician
• Treat with antipyretic medication
• Use leukocyte filter
28
Allergic reactions
• Cause: antibody formation against plasma
proteins
• Signs and symptoms are varied : hives,
itching, respiratory distress
• Treatment: stop blood, notify RN, notify
physician
• Treatment: antihistamines
