Page 14: Administration of Blood and Blood Component

Administration

• Same as whole blood

• To improve transfusion flow, normal saline (50–100 ml) may be added using a Y-pattern infusion set

Page 15: Administration of Blood and Blood Component

RED CELL SUSPENSION

Description• 150–200 ml red cells with minimal

residual plasma to which ±100 ml normal saline, adenine, glucose,mannitol solution (SAGM) or an equivalent red cell nutrient solution has been added

• Haemoglobin approximately 15 g/100 ml• Haematocrit 50%–70%

Page 16: Administration of Blood and Blood Component

Frozen RBCs

• Add cryoprotectant glycerol to RBCs followed by appropriate freezing (-65°C or lower) allows storage of RBCs for 10 years.

• When Cells needed, unit thawed and washed with saline to remove glycerol. Washing “enters” storage bag-unit can be stored for only 24 hours at 1° to 6°C after thawing.

• Used primarily to maintain supplies of uncommon RBC phenotypes needed by patients with alloantibodies against frequently occurring RBC antigens

• Military uses to maintain emergent blood supplies.

Page 17: Administration of Blood and Blood Component

Leukocyte Poor RBCs Leukocyte-Reduced Red

Blood Cells All blood donations have the

white cells removed (>99.99%)

Description• A red cell suspension or

concentrate containing <5 x 106 white cells per pack, prepared by filtration through a leucocyte-depleting filter

• Haemoglobin concentration and haematocrit depend on whether the product is whole blood, red cell concentrate or red cell suspension

• Leucocyte depletion significantly reduces the risk of transmission of cytomegalovirus (CMV)

Page 18: Administration of Blood and Blood Component

Indications

• Minimizes white cell immunization in patients receiving repeated transfusions but, to achieve this, all blood components given to the patient must be leucocyte-depleted

• Reduces risk of CMV transmission in special situations

• Patients who have experienced two or more previous febrile reactions to red cell transfusion

Page 19: Administration of Blood and Blood Component

Contraindications

• Will not prevent graft-vs-host disease:

for this purpose, blood components should be irradiated where facilities are available (radiation dose: 25–30 Gy)

Administration• Same as whole blood

• A leucocyte filter may also be used at the time of transfusion if leucocyte-depleted red cells or whole blood are not available

Page 20: Administration of Blood and Blood Component

Washed RBCs

• Washed RBCS are RBCs washed with saline to remove most of the plasma.

• Washed RBCs are not leukoreduced.• Indications-patients who have had severe

allergic reactions associated with transfusion or immunoglobulin A (IgA) deficiency.

• Washed RBCs must be given through a standard blood filter, can transmit hepatitis and other infectious diseases

• Because bag must be entered to introduce saline, washed RBCs must be given within 24 hrs of preparation.

Page 21: Administration of Blood and Blood Component

IRRADIATED BLOOD COMPONENTS

Irradiated blood products are exposed to approximately 2500 rads of Gamma radiation

to destroy the lymphocyte ’s ability to divide. Transfusion-associated graft-versus-host

disease (TA-GVHD) has not been reported from transfusion of cryoprecipitate or fresh

frozen plasma (FFP), thus these components do not require irradiation. Fresh plasma

(never frozen) for transfusion should be irradiated if the patient is at risk for TA-GVHD.

Page 22: Administration of Blood and Blood Component

Indications

Absolute Indication:1. bone marrow transplant (BMT) recipients

(allogeneic, autologous)2. Cellular (T-cell) Immune Deficiency (congenital

or acquired)3. Intrauterine transfusion4. Transfusions from family members (any

degree)5. Directed donors (when not identified as family

members versus friends)6. HLA-matched platelet transfusions

Page 23: Administration of Blood and Blood Component

Appropriate Indication:

1. hematologic malignancies (leukemias)

2. Hodgkin’s Disease

3. Non-Hodgkin’s Lymphoma

4. Neonatal exchange transfusion

5. Premature infants

6. Certain solid tumors (neuroblastoma,glioblastoma)

Therapeutic Effect

Irradiation destroys the ability of transfused lymphocytes to respond to host foreign antigens thereby preventing graft vs.host disease in susceptible recipients.

Page 25: Administration of Blood and Blood Component

Description

• Pack containing the plasma separated from one whole blood donation within 6 hours of collection and then rapidly frozen to –25°C or colder

• Contains normal plasma levels of stable clotting factors, albumin and immunoglobulin

• Factor VIII level at least 70% of normal fresh plasma level

Page 26: Administration of Blood and Blood Component

FFP• Need ABO

Compatibility, but Rh Neg patients can receive Rh Pos FFP

Page 27: Administration of Blood and Blood Component

Indications

• Replacement of multiple coagulation factor deficiencies: e.g.

—Liver disease

—Warfarin (anticoagulant) overdose

—Depletion of coagulation factors in patients receiving large volume transfusions

• Disseminated intravascular coagulation (DIC)

• Thrombotic thrombocytopenic purpura (TTP)

Page 28: Administration of Blood and Blood Component

Precautions

• Acute allergic reactions are not uncommon, especially with rapid infusions

• Severe life-threatening anaphylactic reactions occasionally occur

• Hypovolaemia alone is not an indication for use

Page 29: Administration of Blood and Blood Component

FFP

• Goal- to raise level of clotting factor to 30% of normal• Takes 10-15 cc/kg or 750-1000 mL for average sized

adult• Infusion time 30-120 minutes• Single dose should restore INR/PT/PTT to normal• Check INR/PT/PTT after infusion to confirm outcome• Rapid reversal of coumadin 5-8cc/kg FFP (Vitamin K

would take 12-18 hours)

• Clin Anes Procedures-Mass Gen-2002

Page 30: Administration of Blood and Blood Component

Description

• Prepared from fresh frozen plasma by collecting the precipitate formed during controlled thawing at +4°C and resuspending it in 10–20 ml plasma

• Contains about half of the Factor VIII and fibrinogen in the donated whole blood: e.g. Factor VIII: 80–100 iu/pack; fibrinogen: 150–300 mg/pack; factor XIII: 40 to 60 U/pack

Page 31: Administration of Blood and Blood Component

Cryoprecipitate

• Shelf life-Frozen: 1 yr (<–30°C)Thawed: Give within 6 hours

• Preferable to be ABO compatible (AABB) May have RBC fragments that can sensitize Rh-D neg patients

Page 32: Administration of Blood and Blood Component

Indications

• As an alternative to Factor VIII concentrate in the treatment of inherited deficiencies of:

— von Willebrand Factor (von Willebrand’s

disease)

— Factor VIII (haemophilia A)

— Factor XIII

• As a source of fibrinogen in acquired coagulopathies: e.g. disseminated intravascular coagulation

Page 33: Administration of Blood and Blood Component

Cryoprecipitate

• A dose of 1 unit (bag) of cryoprecipitate per 7-10 kg body weight raises fibrinogen levels by at least 50 mg/dL.

• The half-life of fibrinogen is 3 to 5 days; additional doses given on the basis of lab test results.

Page 34: Administration of Blood and Blood Component

Platelet Transfusion:

Response evaluation to plt transfusion:

Corrected Count Increment:

( CCI)

CCI= Plt increment multiply BSA/ Number of plt transfused

Page 40: Administration of Blood and Blood Component

Platelet Transfusion:

Response Evaluation:

CCI must be at least 7500 one hour and

4500 ,20 hours after transfusion.

So if it doesn’t occur we can say that patient has platelet resistance.

Page 41: Administration of Blood and Blood Component

Contraindications

• Not generally indicated for prophylaxis of bleeding in surgical patients, unless known to have significant pre-operative platelet deficiency

• Not indicated in: — Idiopathic autoimmune thrombocytopenic purpura (ITP) —Thrombotic thrombocytopenic purpura (TTP) — Untreated disseminated intravascular coagulation (DIC) — Thrombocytopenia associated with septicaemia, until treatment has commenced or in cases of hypersplenism

Page 42: Administration of Blood and Blood Component

Dosage

• 1 unit of platelet concentrate/10 kg body weight: in a 60 or 70 kg adult, 4–6 single donor units containing at least 240 x 109 platelets should raise the platelet count by 20–40 x 109/L

• Increment will be less if there is:

— Splenomegaly

— Disseminated intravascular coagulation

— Septicaemia
