85
Transfusion from compatible donor blood
STANDARD DONATION
86
The client’s blood is collected in anticipation of future transfusions (elective surgery). This blood is designated for and used only by the client.
Clients can donate up to 6 weeks prior to the scheduled surgery. is collected
AUTOLOGOUS TRANSFUSIONS
87
Sterile blood lost during a procedure is saved or retrieved into a device that filters and drains the blood into a bag for transfusion intraoperatively or postoperatively. Reinfusion must occur within 6 hr of salvaged blood collection
INTRAOPERATIVE BLOOD SALVAGE:
88
Platelet Transfusion
Platelets do not need to match the client blood type.
Platelet infusion bags contain 200 to 300 mL.
Must be transfused immediately infused once brought to the client’s room and given over 15 to 30 min using a special transfusion set with a small filter and short tubing.
Vital signs are taken before the infusion, 15 min after the infusion starts, and upon completion.
89
Plasma Transfusion
Plasma is frozen immediately following donation and is then in the form of fresh frozen plasma (FFP).
FFP is transfused as soon as the unit is thawed while clotting factors are still active.
The client can react to the FFP transfusion if the ABO compatibility
Infuse the unit of 200 mL of FFP rapidly over 30 to 60 min through a regular Y-set or straight filtered tubing is not matched
90
Washed packed RBCs
Infuse a unit of 200 mL over 2 to 4 hr.
Administer to a client who has a history of transfusion reactions or to a client who has had a hematopoietic stem cell transplant.
91
WBC Transfusion
Immunocompromised clients rarely receive WBC transfusions because of the risk for severe reaction.
If the client is receiving amphotericin B antibiotics, 4 to 6 hr should be between the administration of the antibiotic and the WBC transfusion because amphotericin B can hemolyze the WBCs.
Infuse WBCs suspended in 400 mL plasma over 45 to 60 min and vital signs are taken every 15 min. The presence of the provider may be required according to agency policy

Excessive bleeding after minimal trauma, surgery
144
Implementations for hemophilia
Provide assistance with coping because it is chronic, places restriction on their lives.
Encourage client to be self-sufficient and maintain independence by preventing unnecessary trauma.
Extensive teaching about activity restrictions to diminish chances of hemorrhage.
Avoid aspirin, NSAIDs, herbs, OTC and alcohol.
Nasal packing should be avoided because frequently resumes when packing is removed.
Avoid all injections.
Invasive procedures should be minimized or performed after administration of factor replacement.
After surgical procedure, assess incision site frequently.
Transfuse factor VIII or IX as prescribed.
145
Caused by deficiency of von Willebrand factor (vWF) which is necessary for Factor VIII activity.
VWF is also necessary for platelet adhesion at the site of vascular injury
Bleeding is mixed in nature
VON WILLEBRAND’S DISEASE
146
Clinical Manifestations of VON WILLEBRAND’S DISEASE
Mucocutaneous i.e. nosebleeds, excessively heavy menses
Deep-tissue bleeding i.e. hemarthrosis, CNS bleeding
147
Implementation for VON WILLEBRAND’S DISEASE
Similar with Hemophilia
Transfuse cryoprecipitate (factor VIII, fibrinogen, factor XIII)
Tranfuse fresh frozen plasma
148
is not a disease but sign of underlying condition
Massive amount of tiny clots forms in the microcirculation.
As the platelets and clotting factors are consumed to form the microthrombi.
Paradoxical effect of excessive clotting is bleeding
DISSEMINATED INTRAVASCULAR COAGULATION
149
Risk Factors for DIC
Sepsis
Obstetric Complications (Abruptio Placenta)
Acute Hemolysis (transfusion reactions)
Trauma
Shock
Cancer (especially cancer and acute promyelocytic leukemia)
Allergic Reactions
150
Clinical Manifestations of DIC
bleeding from venipuncture sites, GIT, GUT
bleeding can range from occult internal bleeding to profuse hemorrhage from all orifices
organ dysfunctions i.e renal failure, pulmonary infarctions, as a result of microthromboses
progressive decrease in platelet count, clotting factors
increased PT, pTT, and FDP
