BLOOD ADMINISTRATION
Blood Administration
Your patient’s Hgb & HCT is 6.2 & 18.4; the doctor orders
2 units of packed RBC’s!
What actions do you take?
Blood Administration
Right If you said:
•Check for T&C
•Verify informed consent
•Insure IV access: prefer large bore catheter (18-20 gauge); smaller bore could cause destruction of RBCs
• Gather equipment
What is T&C vs T&S•What does TYPE mean?
•What does crossmatch mean?
•T&S
*chance blood will be needed
*allows blood bank to be flexible with
blood
•T&C
*pt will need blood
*ties up inventory, blood is set aside for
that particular patient for 3 days
Blood AdministrationObjectives
Discuss:
•Common blood products
•Steps in blood administration
•Complications of blood administration
•Always consult specific hospital policy
Types of Blood Components • Whole Blood
• To replace blood volume and O2 carrying capacity in
• Treat hemorrhage and shock• Contains PRB’C, plasma proteins, clotting
factors and plasma(few platelets & granulocytes)Volume = 500ml/unit__________________
• Packed Red cells (PRBCs)• Treat anemia, replace blood volume
(ordered when Hgb 8-9 & HCT 24-27)• 1 unit PRBC = Hgb by 1/HCT by 3• From whole blood (2/3 of plasma
removed)• Only RBCs used• Purpose: O2 carrying capacity in
patients with slow bleeding, anemia, leukemia, surgery
Volume = 300-350ml/unit
Risks & Benefits• Possible incompatibility issues• Circulatory overload• **Deficient in some clotting factors• Rarely used• Use Lasix to prevent overload
________________Risks & Benefits• Use leukocyte poor red cells or
leukocyte filter if history of febrile reaction
• No viable platelets or granulocytes• Incompatibility may cause
hemolytic reaction• Less chance of fluid overload than
whole blood• Takes 4-6 hours for Hgb & HCT to
change• Shelf life: 42 days (takes 1 day to process)• Most commonly used!!
Current Blood Preparation
• Leukocyte reduction prior to storage• Removal of most WBC’s and Plasma reduces the risk of reactions
• Irradiated• for those with CA or risk for GVHD • good for 28 days
• Drawback• bacterial growth if contaminated during collection/processing
Types of Blood Components Con’t
• Platelets • To control or prevent bleeding in platelet
deficiencies, i.e. thrombocytopenia(often ordered when platelets count <10-20,000)• From whole fresh blood• Expected platelet 10,000/unit• Measure at 1hr & 18-24 hr post admin
Volume = 30-60ml/unit________________________
• Albumin (plasma derivative)• To expand blood volume or replace
protein• Used to treat shock from trauma,
infection, 3rd spacing, hypovolemia, burns and in surgery
• Available in 5% -25% solution• Paid donation
Volume 25g/100ml = 500ml of plasma
Risks & Benefits• Not a substitute for whole blood• May form antibodies• Hypersensitivity reaction• Must be used within 5 days of
donation
_______________
Risks & Benefits• Vascular overload • Hyperosmolar solution moves
water from extravascular space to intravascular space
• Outcome: adequate BP & volume• Hypersensitivity reaction• Can be stored for 5 years
Types of Blood Components cont’d
• Frozen RBCs• Rarely used• Successive washing with
saline solution removes majority of WBCs and plasma proteins
________________________
• Fresh Frozen Plasma (FFP)• To treat DIC, reverse effects of
Coumadin, treat liver failure pts• Contains clotting factors• Improves coagulation, PT &
PTTVolume = 200-250ml/unit
Risks and Benefits - Can be stored for 3 years - Use within 24hrs of thawing - No WBC’s___________________
Risks & Benefits• Rich in clotting factors• No platelets• Good for volume expansion to
restore clotting factors in hypovolemic shock
• Risk for vascular overload• Hypersensitivity reaction• Hemolytic reactions
Types of Blood Components Cont’d
• Prothrombin Complex – Prothrombin, Factors VII, IX, X, and part of XI• Used to treat clients with specific clotting factor
deficiencies• Prepared from FFP• Store for 1 year, once thawed, must be used
• Cryoprecipitate – Clotting Factors VIII, XIII, von Willebrand’s factor, & fibrinogen from plasma• Used to treat clients with specific clotting factor deficiencies• May cause ABO incompatibilities

Donor Eligibility• Donor Eligibility Resource
*Preparation for Blood Administration*
• Physicians order• Look at labs • Verify/sign consent*• Obtain IV access, large bore catheter (18-20 gauge), 2 lines if possible
• *Get client ready for transfusion prior to getting blood from the lab• T&C done • Gather supplies • *Staff signs for and obtains blood (only one client & 1 unit a time!)• Routine compatibility testing takes about 1 hour to identify recipient ABO
and Rh type; in emergency O-negative RBC’s can be safely given to most clients without serologic testing.
• Why can O-neg blood be safely given to most people? • *Universal RBC donor is O negative
• 2 RN check at the bedside with patient chart (see next slide for 2 RN check)• Blood admin must be completed within 3-4 hours after receipt from blood
bank!
2 RN checkWhat do you check for?• Entire process needs 2 RN independent double check at bedside• Verify informed consent• Check physician’s orders
• Match this information to the information on label on blood, lab sheet, patient blood band, and the chart:• Name, DOB, MR#, Blood Band #, unit expiration date, unit number,
blood type (group and Rh)
90% of all reactions occur because of mistakes in labeling and verification
• IV 18-20 gauge adult, 23-child • 0.9% Sodium Chloride (NS) only• Prime Y-type blood tubing with NS, before admin/picking up blood.• Clamp off NS• Pick blood up from blood bank/invert unit to mix cells (do not shake it) • Compare all labels second time• Be prepared – once you begin, don’t leave the room• Spike blood bag• Squeeze tubing to cover blood filter with blood• Set pump – start slow• Check vital signs and record – educate pt on what to look for
• Initial vitals before admin (RR, Temp, HR, BP)• Vitals 15 minutes after admin. (stay with pt 1st 15mins)• Vitals q30min after that until transfusion complete• Vitals post admin. and then in 1hr
• If unable to give blood – must be returned within 15-30 minutes of removing from lab – DO NOT STORE IN UNIT REFRIGERATOR
Blood Product Blood Product AdministrationAdministration
• Use appropriate filters• Use blood administration set no more than 4 hours – infusion must be complete in 4 hours
• New unit, use new set• Always follow hospital specific blood administration policy
Blood to cover filterBlood to cover filter
Blood Product Administration
• Flush IV site with NS• Post administration vitals• Dispose of tubing and blood bag in biohazard bag
• If a 2nd unit is ordered: • Prime new tubing with new NS bag• Retrieve 2nd unit• Repeat RN checks
• Document:• When started & ended• Volume infused• Premeds given• How the pt tolerated procedure• Protocols followed
Post Administration
• Monitor for signs of transfusion reaction• Infuse over ordered period• Blood cannot be out of refrigerator more than 30 minutes prior to administration –PLAN AHEAD!!
• BE READY TO START BEFORE GETTING BLOOD!!
• Allow blood to hang no longer than 4 hours • If multiple units to be given for replacement of rapid blood loss, may be given under pressure and warmed prior to administration (only agency approved warming device)
Critical Points
How would you manage this?
1. Your client is to receive a unit of packed red blood cells. You have picked the blood up from the blood bank and brought it to the unit. You flush the patient’s IV before hanging the blood and find that it has infiltrated. You are unable to initiate IV access. What actions should you take?
2. Your client is to receive a unit of RBC’s for a Hgb/HCT of 8/22…
How will the order be written?
What response to this unit of blood is anticipated (related to the Hgb/HCT)?
Transfusion Reactions
Vital signs taken prior to start of infusion are critical
Blood transfusion reaction: adverse reaction to blood therapy: range from mild symptoms to life threatening; can be acute or delayed!
•What vital signs might you see?
•Consider a temperature increase of 1 degree significant
Action taken will be determined by the type of reaction; careful assessment & monitoring of the patient is a must!
Transfusion Reactions/Complications
• Febrile (most common)• Sensitization to donor WBC, platelets, plasma proteins
• Allergic (hypersensitivity to donor plasma proteins)• Mild allergic to severe (anaphylactic)
• Hemolytic (life-threatening!)• Acute hemolytic: ABO incompatible; red cell destruction (wrong blood
type given to pt)
• Circulatory overload• Fluid given too fast & too much
• TRALI• Transfusion reaction acute lung injury• Non cardiogenic pulmonary edema
• Bacterial (pyrogenic or sepsis) • Transfusion of bacterially infected components
Febrilepyrogenic /non-hemolytic
Caused by leukocyte incompatibility; sudden onset: usually within first 15 minutes of transfusion!
(usually a reaction to donor WBC’s or plasma proteins)
• Fever/chills (^1 degree)• Sensations of cold• Flushed skin, abdominal pain,
vomiting and diarrhea• Hypotension/Shock
• Prevent by use of leukocyte poor blood!
• Stop infusion/antipyretics• Call MD
**Bacterial (pyrogenic): similar to febrile; due to bacterial contamination of blood:
see S & S above
Allergic Reactions (hypersensitivity reactions)
Mild (initially) (1% of pts.)• Urticaria• Pruritis
Severe (Anaphylactic)• Anxiety• Wheezing & Chest tightness• Dyspnea• Bronchospasm• Hypotension• Tachycardia• Swelling of tongue, face• Loss of consciousness• Shock, pulmonary edema
Antibodies in patient’s blood react against proteins, such as immunoglobulin A in donor blood
May occur during or after the transfusion
Can occur quickly, within 50mls of blood administered
Mild and transient: stop infusion, alert MD, give antihistamine prophylactically, use washed RBCs
Severe: stop infusion, keep line open with new saline & tubing; CPR & epinephrine (if indicated)
DO NOT RESTART TRANSFUSION
Hemolytic Transfusion Reaction!Most dangerous! Develops within first 15 minutes of
transfusion: free hemoglobin in blood and urine specimens provide evidence of acute hemolytic reaction
Occurs in 1:25,000
Usually occurs after 50-100 ml blood infused! (possibly 200mls)
ABO/Blood incompatibility• *RBC’s clump (lysis of RBC’c), block
capillaries, decrease blood flow to organs• Hgb released (myogloburia), blocks renal
tubules > acute renal failure=ATN (acute tubular necrosis)
• Potassium released
•Fever/chills•SOB/dyspnea/wheezing•Apprehension•Headache/low back pain•Chest pain/chest tightness•Urticaria•Tachycardia•N&V•Hematuria •Burning at IV site
Hemolytic Transfusion Reaction!If hemolytic reaction occurs:
Stop transfusion, keep IV line open with new tubing, saline, possible colloid solution to maintain BP; monitor
Notify MD of patient signs and symptoms
Treat shock (anaphylactic) if present (epinephrine, oxygen, antihistamines, vasopressors, fluids, corticosteroids)
Draw blood samples for serologic testing; send urine to lab and return blood & tubing to blood bank for free Hgb testing & crossmatch verification
Prevent acute renal failure: give diuretic, fluid challenge
Stop the blood, send tubing and remaining blood to lab; urine to lab!
Follow facility policy and procedure for administering blood, blood products and transfusion reaction!
ABO incompatibility causes RBC’s to clump, block capillaries, decreasing blood flow to organs.
Hgb is released blocking renal tubules Can cause renal failure.
Hemolytic Reactions Hemolytic Reactions
Hemolytic Reactions
Key Indicators:• Apprehension Fever/chills• Headache Burning at IV site• Chest pain Low back pain• Tachycardia Hypotension• Urticaria • N/V
• Acute-usually occurs after 50 ml. infused Lewis – can occur within infusion of as little as 10mls
• Circulatory overload• Fluid given too fast & too much• Note cough, dyspnea, lung sounds, HTN etc• Slow infusion, elevate HOB, treat overload
• Iron overload • Delayed reaction• Vomiting diarrhea, hypotension, altered hematological
values
Reactions/Complications
Nursing actions if reaction occurs
• Stop transfusion immediately• Continue Normal Saline IV with new tubing• Provide appropriate care for client• Notify physician of client signs and symptoms• Follow facility policy and procedure • Obtain urine & blood specimen for free hemoglobin
test
Autotransfusion (autologous transfusion)Indications
• Used in surgery & emergency settings
• Autologous blood-collection of own blood prior to scheduled surgery
Risks and Benefits• Requires special
equipment• If pre-donation, begin
collection within 5 weeks of transfusion date end at least 3 days prior to transfusion need
“Cell-saver" technology collects blood
lost during surgery, cleanses it, and places it back in the patient's body, all in a continuous loop.
Autotransfusion
What are the benefits of Autologous transfusion?• Blood you receive should definitely match yours.• Risk of getting any allergic reaction will be very low. • Blood will be available if you have a rare blood type.• No infectious diseases - hepatitis, syphilis, AIDS, etc.
What are the issues related to Autologous transfusion? • Usually the pateint is already medically not well• 2/3 of donations do not get used• Many end up in the hospital post procedure
Autotransfusion
Who can have Autologous transfusion?
Patients less than 65 years old.
Patients without serious medical conditions like serious heart and lung diseases.
Patient’s with hemoglobin level of at least 11g / dl before each donation
Every unit of blood is tested Every unit of blood is tested forfor
Antibodies to HIV-1 and HIV-2 (AIDS).
Antibodies to HBV produced during and after infection with Hepatitis B Virus
Antibodies to HCV produced after infection with the Hepatitis C virus
Antibodies to HTLV-I/II produced after infection with Human T-Lymphotropic Virus (HTLV-I and HTLV-II) Antibodies to HBsAg produced after infection with Hepatitis B
For blood type (ABO) and Rh factor Tp, the agent that causes syphilis ALT, an elevated ALT may indicate liver inflammation, which may be caused by a hepatitis virus
The presence of unexpected antibodies that may cause reactions after the transfusion
CMV, a test for the cytomegalovirus (performed on physician request)
NAT (Nucleic Acid Testing) - a new technology that can detect the genetic material of Hepatitis C and HIV to identify these viruses faster and more accurately
100% of the blood products are filtered to 100% of the blood products are filtered to remove leukocytes that can harbor viruses remove leukocytes that can harbor viruses and infections.and infections.
