  9. 9. Blood & Blood Products• Donated Blood are leucodepleted as a precaution against creutzfeldt-Jakob Diseases (transmissible spongiform encephalopathies )
  10. 10. Types of Blood Available1. Whole Blood2. Packed Red Cells3. Fresh Frozen Plasma4. Cryoprecipitate5. Platelets6. Prothrombin Complex Concentrates7. Autologous blood
  11. 11. Packed red cells• Packed red blood cells are cells that are spun down and concentrated. Each unit is approximately 330ml and has a haematocrit of 50- 70%. Packed cells are stored in a SAG-M solution (Saline-adenine-glucose-mannitol)to increase their shelf-life to 5 weeks at 2-60C. (Older storage regimens included storage in CPD – citrate- Phosphate-dextrose solutions –giving cells a shelf- life of 2-3 weeks).
  12. 12. Fresh Frozen PlasmaFFP is rich in coagulation factors• It is removed from fresh blood and stored at -40 to 50 0C with a 2 year shelf life.• It is the first line therapy in the treatment of coagulopathic haemorrhage.• Rhesus D positive FFP may be given to a Rhesus D negative woman
  13. 13. Cryoprecipitate• Cryoprecipitate is a supernatant precipitate of FFp and is rich In factor VIII and fibrinogen.• It is stored at -30oC with a 2 year shelf life.• It is given in low fibrinogen states or in cases of factor VIII deficiency.
  14. 14. Platelets• Platelets are supplied as a pooled platelet concentrate containing about 250×109 cells per litre.• Platelets are stored on a special agitator at 20-240 C and have a shelf life of only 5 days• Platelets Transfusions are given to patients with thrombocycopenia.
  15. 15. Prothrombin Complex Concentrates• Prothrombin complex concentrates (PCCs) are highly purified concentrates prepared frompooled plasma.• They contain factors II,IX and X; factor VII may be included or produced seperately.• PCCs are indicated for the emergency reversal of anti- coagulant (warfarin) therapy in uncontrolled haemorrhage.
  16. 16. Autologous blood• Pre donation of their own blood patients undergoing elective surgery up to 3 weeks surgery of retransfusion.• Collected in a cell saver, ( which washes and collects red blood cells) which can then be returned to the patient.
  17. 17. Indication of blood Transfusion• Acute blood loss, to replace circulating volume and maintain oxygen delivery• Perioperative anaemia, to ensure adequate oxygen delivery during to perioperative phase• Symptomatic chronic anaemia without hemorrhage or impending surgery.
  18. 18. Indications for blood TransfusionHaemoglobin level (g dl-1) INDICATION <6 Probably will benefit from transfusion 6-8 Transfusion unlikely to be of benefit in the absence of bleeding or impending surgery >8 No indication for transfusion
  19. 19. Blood Groups and Cross Matching• ABO System – The system consists of 3 allelic genes A, B & O. – Control the synthesis of enzymes that add carbohydrate residues to cell surface glycoproteins – A & B genes result in specific residues – The O gene is an amorph & doesn’t transform the glycoprotein. – The system allows for six possible genotypes although there are four phenotypes.
  20. 20. ABO blood group SystemPhenotype Genotype Antigen Antibodies Frequency (%)O OO O Anti-A, Anti-B 46A AA or AO A Anti-B 42B BB or BO B Anti-A 9AB AB AB None 3 Rhesus SystemThe Rhesus D [Rh(D)] antigen is strongly antigenic.Antibodies to the D antigen are not naturally present in the serum of theremaining 15% of individuals but their formation may be stimulated by thetransfusion of Rh-positive red cells or they may be acquired during delivery ofa Rh(D) positive baby.
  21. 21. TRANSFUSION REACTIONS• is any unfavorable transfusion-related event occurring in a patient during or after transfusion of blood components
  22. 22. TRANSFUSION REACTIONS@RBC’s !• Nonhemolytic 1-5 % transfusions Causes -Physical or chemical destruction of blood: freezing, heating, hemolytic drug -solution added to blood -Bacterial contamination : fever, chills, urticaria – Slow transfusion, diphenhydramine , antipyretic for fever• Hemolytic – Immediate: ABO incompatibility (1/ 12-33,000) with fatality (1/ 500-800,000) Majority are group O patients receiving type A, B or AB blood Complement activation, RBC lysis, free Hb (+ direct Coombs Ab test)
  23. 23. Cross Matching• Full cross matching of blood takes 45 min in most laboratories.• In more urgent situations, “type-specific” blood is provided can be issued within 10-15 min.• When blood must be given in an emergency, group O (Universal donor) blood is given (O- to female patients, O+ to male patients)
  24. 24. Complications of blood Transfusion• From a Single Transfusion – Incompatibility haemolytic transfusion reaction – Febrile transfusion reaction – Allergic reaction – Infection • Bacterial infection (usually as a result of faculty storage) • Hepatitis • HIV • Malaria – Air embolism – Thrombophylebitis – Transfusion related acute lung injury (usually from FFP)
  25. 25. Complications of blood Transfusion• From Massive Transfusion – Coagulopathy – Hypocalcaemia – Hyperkalaemia – Hypokalaemia – Hypothermia Patient who receive repeated transfusions e.g Patient with thalessaemia may develop iron overload
  26. 26. Management of Coagulopathy• Standard Guidelines – FFP if prothrombin time (PT) or partial Thromboplastin time (PTT) > 1.5 × normal – Cryoprecipitate if fibrinogen < 0.8 gl-1 – Platelets if platelet count < 50 × 109 ml-1
  27. 27. Blood Substitutes• Blood substitutes are either biomimetic or abiotic – Biomimetic substitutes mimic the standard oxygen- carrying capacity of the blood and are haemoglobin based – Abiotic substutes are synthetic oxygen carriers and are currently primarily per fluorocarbon based.
  28. 28. Plasma Expanders• Dextran is a complex, branched glucan (polysaccharide made of many glucose molecules) composed of chains of varying lengths (from 3 to 2000 kilodaltons). It is used medicinally as an antithrombotic (anti- platelet), to reduce blood viscosity, and as a volume expander in anemia.
  29. 29. “Blood is still the best possible thing to have in our veins” - Woody Allen Blood transfusion is a lot like marriage.It should not be entered upon lightly, unadvisedly or wantonly, or more often than is absolutely necessary” - Beal
