Blood Administration NUR 112 Objectives • Identify common blood products • List steps in blood administration • Identify nursing responsibilities related to administration of blood products • Identify complications of blood administration • Describe methods of blood donations Blood Administration •Check for T& C (3 days) •Verify informed consent •Insure IV access; need large bore catheter (18-23 gauge); smaller bore causes destruction of RBC’s and slow blood administration. • Gather equipment: • Y-tubing blood administration set with filter •NS solution •IV pump •Prime tubing with 0.9NS Blood Components • CURRENTLY USED – – – – – – Packed RBC’s Frozen RBC’s Platelets Fresh Frozen Plasma Albumin Cryoprecipitates & commercial concentrates • Rarely USED – Whole blood Current Blood Preparation • Leukocyte reduction prior to storage • More effective than previous washing process • Packed RBC’s removed from plasma • Removal of most WBC’s and Plasma reduces risk of reactions • Drawback – bacterial growth if contaminated during collection/processing 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!! Types of Blood Components con’t • Platelets Risks & Benefits – Control or prevent bleeding in platelet deficiencies, i.e. thrombocytopenia-(ordered when – – – – – platelets count <10-20,000 - unless? – From whole fresh blood(plateletpharesis) – Expected platelet 10,000uL/U – Measure at 1hr & 18-24 hr post admin Platelet donations Volume = 30-60ml/unit ________________________ • 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 Albumin (plasma derivative) – Expand blood volume or replace protein – Treat shock from trauma, infection, 3rd spacing, hypovolemia, *hypoalbuminemia burns and in surgery, – Available in 5% -25% solution – Paid donation Volume 25g/100ml = 500ml of plasma Not a substitute for whole blood May form antibodies Hypersensitivity reaction Use within 5 days of donation Can keep at room temp depending upon storage/collection • Albumin therapy Types of Blood Components cont • • Risks and Benefits - Store for 10 years/use within 24 hr Frozen RBCs thawing – Rarely used * - Use within 24hrs of thawing – Successive washing with saline - *Atotransfusion; stockpiling or removes most WBCs & plasma rare donors for patients with proteins ________________________ alloantibodies ___________________ Fresh Frozen Plasma (FFP) Risks & Benefits – Treat DIC, reverse effects of – No platelets Coumadin, treat liver failure pts – Use for volume expansion to – From liquid portion whole blood, restore clotting factors in separated from cells > frozen hypovolemic shock- being – *Rich in clotting factors replaced by albumin plasma – Volume = 200-250ml/unit expanders. (from text) – Outcome- Improved coagulation, PT – Can store for 1 yr; *use within 2 & PTT hrs post thawing – Risk for vascular overload /hypersensitivity reaction/ Hemolytic reactions Types of Blood Components cont • Prothrombin Complex – Prothrombin, Factors VII, IX, X, and part of XI – Used to treat clients with specific clotting factor deficiencies • 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 – Prepared from FFP – Store for 1 year, once thawed > use Autotransfusion or Autologous Transfusion Autotransfusion (autologous transfusion) Indications Risks & Benefit – Used in surgery & emergency – Special equipment required settings – Autologous –collection of own – No T & C required blood scheduled surgery or in – Minimal risk of allergic emergency situation (blood reaction; *monitor salvage; cell saver) coagulation – Blood available if rare blood type – *No infections diseasehepatitis, syphillis, HIV, etc – Safe, well tested – *Drainage after 1st 24 hrs not used; may contain pathogens “Cell-saver“ collects blood lost during surgery, cleanses it, returns to patient's body, all in a continuous loop. For intraoperatively salvaged washed blood- filters•Reduces leukocytes •Dec fat globules Reduces microaggregates Autologous Donation/Elective Phlebotomy Who can make Autologous donation? (predeposit transfusion) Less than 65 years old (usually). Without serious medical conditions like serious heart and lung diseases. Start before planned surgery- (about 5 weeks); have hemoglobin level of at least 11g / dl before each donation *Store up to 10 years, if frozen, given within a few weeks of donation Blood Transfusions RBC & Plasma Transfusions-Compatibility O- universal donor, AB+ universal recipient ABO Compatibility Chart • Who is universal donor & recipient? • What do the - & + mean? Who Can Donate Blood? Paid vs Volunteer – what is the difference? What percentage of population can donate? How many do? Who cannot donate? In Europe in the 80’s & 90’s – indefinitely Previous history of malaria – years Incarceration for 72 hours – 1 yr Hepatitis after age 11 – indefinitely HCT < 38% until resolved Homosexual Male after 1977 – indefinitely Needle stick – 1 yr Medical history of vascular disease, bleeding or cancer - until resolved * 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 patient ready for transfusion prior to getting blood from the lab T&C Gather supplies *Staff signs for and obtains blood (only one patient & 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 without serologic testing. • Why can O-neg blood be safely given to most people? – *Universal RBC donor is O negative; universal recipient is AB positive • 2 RN check at bedside with patient chart (see next slide for 2 RN check) • Blood admin must complete within 3-4 hours after receipt from blood bank! 2 RN check What do you check for? • Verify informed consent • Check physician’s orders • Match this information to the information on lab slip and the chart: – Name, DOB, MR#, Blood Band #, unit expiration date, unit number, blood type (group and Rh) *Remember know agency policy for blood administration 90% of all reactions occur because of mistakes in labeling and verification Initiation of Transfusion *at bedside • 2 RNs (or licensed staff according to state NPA and agency policy) check unit of blood with laboratory slip, patient’s chart, forms include patient’s name, unit #, and blood type, etc. • Check expiration date • Patient’s ID#, blood band #, & state name (@ St. David’s – blood band number on blood band) (@ Seton - transfusion card/follow policy) • Blood component, donor #, expiration date, Group & Rh factor (If blood not to be given, must be returned to blood bank within 30 minutes; CANNOT be kept in unit refrigerator (requires special refrigeration)!) Verify Identification Blood Product Administration •Use appropriate filters •Use blood administration set no more than 4 hours – infusion must be complete in 4 hours • Check facility policy re: # units per administration set •May give blood per pump sing blood pump tubing Saddleback NursingBlood Transfusions Blood Product Administration * at bedside • Compare all labels second time • Check vital signs and record – Initial vitals before admin. – Vitals 15 minutes after admin. (stay with pt 1st 15mins) – Vitals q30min after that until transfusion complete – Vitals post admin. and then in 1hrd • • • • • 0.9% Sodium Chloride (NS) only!!!*remember Invert unit to mix cells Prime Y-type blood tubing with NS, before admin. Spike blood bag, clamp off NS Squeeze tubing to cover blood filter with blood Post 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 • Can you use the same NS bag? – Retrieve 2nd unit – Repeat RN checks • Document: – – – – – When started & ended Volume infused Premeds given How the pt tolerated procedure Protocols followed Critical Points • • • • Correct MD order/permit; patient identification & blood compatibility Correct blood tubing, blood set-up, saline only (No other solutions/medications/products with blood-other than saline) Follow procedure for measurement vital signs, starting infusion etc. Drip rate no higher than 2 ml per minute X 15 minutes (30 cc per 15 minutes or 120 cc/hr.) – Seton etc. set pump at 75 to 80 cc/hr. for 15 min. – Remain with pt for first 15 minutes – Vital signs prior to administration, in 15 minutes, then q 30 minutes, until transfusion complete--then X 2 • *Rapid blood replacement-use blood warmer • “Other blood components FFP and platelets, can infuse over 1530 min. More Critical Points • Monitor for signs of transfusion reaction • Infuse over period specified (2-4 hours) and rememberblood cannot be out of refrigerator (blood bank) more than 30 minutes prior to administration –PLAN AHEAD!! • BE READY TO START BEFORE GETTING BLOOD!! • If multiple units required as in cases of rapid blood lossmay be given under pressure and warmed prior to administration (only agency approved warming device) How would you manage this? 1. A patient is to receive a unit of packed red blood cells. The blood has been obtained from the blood bank and brought to the unit. The nurse flushes the patient’s IV prior to hanging the blood and finds that the IV has infiltrated. What action(s) should the nurse take? How would you manage this? 2. In addition to transfusion reaction; what is a major risk related to administration of whole blood? Transfusion Reactions Blood transfusion reaction: adverse reaction to blood therapy: range from mild symptoms to life threatening; can be acute or delayed! •What vital signs would you expect to see? Vital signs taken prior to start of infusion critical; may actually give blood even if patient has slight temp elevation; must inform MD and Tylenol might be administered! •Consider a temperature increase of 1 degrees significant Action taken will be determined by type of reaction; careful assessment, monitoring of patient! Transfusion Reactions/Complications • Acute Transfusion Reactions – Acute hemolytic – Febrile-non hemolytic – Allergic –mild – Allergic-Anaphylactic/severe – Septic – Circulatory overload – Transfusion-related lung injury (TRALI) – Massive Blood Transfusion Reactions • Delayed Transfusion Reactions – Delayed hemolytic – Infections – Iron overload – Other Transfusion Reactions/Complications • Hemolytic (life-threatening!) – Acute hemolytic: ABO incompatible; red cell destruction (wrong blood type given to pt) • Febrile (most common) – Sensitization to donor WBC, platelets, plasma proteins • Allergic (hypersensitivity to donor plasma proteins) – Mild allergic to severe -Anaphylactic) • Septic: transfusion bacterially contaminated blood • *Circulatory overload – Fluid given too fast & too much • *TRALI: sudden onset-non-cardiogenic pulmonary edema (transfusion related acute lung injury) • Massive Blood Transfusion Reaction: – Clotting issues, citrate toxicity, hypocalcemia Hemolytic/Transfusion Reaction! Most dangerous! Develops within first 15 minutes of transfusion: free hemoglobin in blood and urine specimens > acute hemolytic reaction; delayed at 2-14 days Occurs in 1:25,000 Occurs after approx 50 ml blood infused! Blood incompatibility (ABO 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) •Fever/chills •SOB/dyspnea/wheezing •Apprehension •Headache/low back pain •Chest pain/chest tightness •Urticaria/tachycardia •*Hematuria Hemolytic Reactions *Hgb is released blocking renal tubules-can cause renal failure. Hemolytic Reactions Key Indicators: – – – – – – Apprehension Headache Chest pain Tachycardia Urticaria N/V Fever/chills Burning at IV site Low back pain Hypotension • Acute-usually occurs after 50 ml. infused (could be <10 mL) Febrile Caused by leukocyte incompatibility; sudden onset: usually within first 15 minutes of transfusion! • • • • Fever/chills (^1 degree) Sensations of Cold Hypotension/Shock Flushed skin, abdominal pain, vomiting and diarrhea **Bacterial (pyrogenic): • Prevent by use of leukocyte poor blood! • Stop infusion/antipyretics similar to febrile; due to bacterial contamination of blood: see S & S above Allergic Reactions (Hypersensitivity reactions) Antibodies in patient’s blood react Severe (Anaphylactic) – – – – – – – – 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 (initially) (1% of pts.) *Urticaria Pruritis Itching Mild and transient: stop infusion, possibly restart, give antihistamine prophylactically, use washed RBCs Anxiety Wheezing Dyspnea Bronchospasm Hypotension Swelling of tongue, face Loss of consciousness Shock, pulmonary edema • Stop infusion, keep line open with new saline tubing; CPR & epinephrine (if indicated) • DO NOT RESTART TRANSFUSION Reactions/Complications • *Circulatory overload – Fluid given too fast & too much – Note cough, dyspnea, lung sounds, HTN etc – Slow infusion, elevate HOB, treat overload, phlebotomy • Iron overload (delayed) – Delayed reaction – Vomiting diarrhea, hypotension, altered hematological values – Administer deferoxamine (Desferal) Iv to remove accumulated iron via the kidneys (urine red) • Hypocalcemia (massive blood transfusions) – Citrate in blood binds with calcium & is excreted – Check lab values • Hyperkalemia: stored blood liberates potassium through hemolysis (“older” blood greater risk for hemolysis)* significance of elevated potassium? Hemolytic Transfusion Reaction! If hemolytic reaction occurs: • Stop transfusion •, Keep IV line open/new tubing saline solution, maintain BP; monitor •Notify HCP and blood bank immediatelysigns/symptoms; recheck identifying tags/ numbers •Monitor VS, urine output •Treat symptoms- shock (anaphylactic) if present (epinephrine, oxygen, antihistamines, vasopressors, fluids, corticosteroids) •Save blood bag, tubing, send to blood bank for exam •Complete transfusion reaction reports •Collect required blood, urine samples as per policy to ck for hemolysis •Document on transfusion reaction form and patient chart • Prevent acute renal failure-diuretic, fluids 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! Review What is a primary purpose of administering blood and blood components? A. treat hypervolemia. NO…Blood and its components inc intravascular volume, not dec. Potential complication with administration of blood esp when given too rapidly > hypervolemia. B. C. D. alleviate sodium retention. NO…Alleviate sodium retention: an answer for consideration; indirectly sodium retention might dec by effect on restoration of intravascular volume and normal hemodynamics (renin-angiotensinaldosterone) inc the level of electrolytes. NO…Inc level of electrolytes…perhaps indirectly as normal hemodynamics restored, not primary reason for giving blood and blood products. promote tissue oxygenation. YES…RBC’s carry oxygen! Blood and components also provide clotting factors and maintain intravascular volume.) Platelets are used to treat? A. Hemophilia No Platelets do not contain the specific clotting factors needed by a client with hemophilia; platelet levels are typically normal B. Thrombocytopenia RIGHT Platelets (if normal) release thromboxane to cause vessel; spasm when there is damage to a vessel activates the clotting pathway to convert fibrinogen to fibrin C. Polycythemia No Polycythemia is the presence of excess RBC’s; administration of platelets would not decrease the abnormal amount of RBCs in fact would cause increased problems…increased viscosity and more likely to form clots. D. Low white cell count No WBCs are leukocytes and originate from hemopoietic stem cells in the bone marrow; must use hematopoietic growth factors to stimulate granulocyte maturation and differentiation Ethical Implications • An elderly woman with dementia, transferred from a nursing home due to GI bleeding. Some of her family members tell the nurse that she is a Jehovah’s Witness and must not receive blood products. The surgeon indicates that if she does not have exploratory surgery and receive blood products, she will die. – – – – What actions will you as her nurse take? What resources do you have available to consult? How can you determine if the family is acting is the patient’s best interest? What non-blood alternatives are available for Jevohah’s Witnesses or others who do not wish to receive blood products? FYI-Every unit of blood is tested for 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- agent that causes syphilis *ALT,-elevated ALT may indicate liver inflammation, which may be caused by a hepatitis virus 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) - new technology that can detect genetic material of Hepatitis C and HIV to identify these viruses faster and more accurately All blood products filtered to remove leukocytes that can harbor viruses and infections
