What is blood? • A highly specialised circulating tissue which has several types of cells suspended in a liquid medium called plasma. • Origins from Greek ‘haima’ • Blood is a life sustaining fluid 428 surgery team
Blood is an amazing fluid! • Keeps us warm • Provides nutrients for cells, tissues and organs • Removes waste products from various sites 428 surgery team
Blood Composition • Plasma: 55%. (50% water + 5% plasma substance) • Formed elements: 45%. • - RBC: live in circulation for 120 days. (near 45%) • - WBC: their life in circulation extends from months to years. • - Platelets: their life in circulation is 6-10 days. WBC + platelets less than 1% 428 surgery team
Blood components • Blood Products: • Whole Blood • Packed red cells RBC. • Platelets concentrate. • White cell concentrate. • Plasma Products: • Fresh Frozen Plasma FFP. • Frozen plasma • Cryoprecipitate. • Albumin containing solution. • Human Immunoglobulins. • Prothrombin complex concentrate. • Factor VIII concentrates. 428 surgery team
Whole Blood Centrifugation Platelet – rich Plasma Red Cell Concentrate Centrifugation Platele – poor Plasma Platelet Concentration Freezing - 30° C 428 surgery team
Fresh Frozen Plasma (FFP) Cryoprecipitation 4° C Supernatant Precipitate (cryoprecipitate) Factor VIII Concentrate Precipitate (fibrinogen) Supernatant Plasma Protein Fraction (PPF) Albumin Prothrombin Complex Concentrate Immunoglobulins 428 surgery team
Packed Red Blood Cells • One unit contains 300 ml. • Out of this, 70% are RBC. • Indicated in: • - Acute blood loss, • - Chronic anemias. • Shelf life 42 days at 4 C 428 surgery team
Platelet Concentrate • One unit contains 50 x 109 platelets. • Usually 5-6 units are given as one pool. • Indicated in: • - Bleeding due to platelet deficiency. • - Bleeding due to platelet dysfunction. • Shelf life 5 day at 22 C 428 surgery team
WBC Concentrate • Difficult to get sufficient quantities. • Half life is only 8 hours. • Rarely indicated because most patients respond to antibiotics and do not need white blood cells. • Nonhemolytic transfusion reactions are common. 428 surgery team
Plasma Products • 1. Fresh frozen plasma (FFP): • Stored at – 30° C. • Shelf life 1 year. • Rich in all components of plasma. • Indicated in: • - Disseminated intravascular coagulation (DIC). • - Liver failure. • - Warfarin overdose. • - Massive RBC transfusions. 428 surgery team
2- Cryoprecipitate • Prepared from FFP after thawing it to 4° C. • When refrozen, the shelf life is 3 to 6 months. • Rich in factors VIII, XII, XIII and VWF (Von Willebrand factor). • 3- Factor VIII concentrate: • Prepared by fractionation of cryoprecipitate. • Large numbers of cryoprecipitate are required. • Indicated in hemophilia. Type A 428 surgery team
4- prothrombin complex concentrate: • Contains factors II, VII, IX, and X. • Indicated in hemophilia B. • 5- Human immunoglobulins: • Nonspecific immunoglobulins are used in: • - Congenital immunodeficiencies. • - Acquired immunodeficiencies. • - Idiopathic thrombocytopenia purpura (ITP). • Specific immunoglobulins are used in: • - Hepatitis B. • - Herpes zoster. • - Rubella. • - Rabies. • - Tetanus. • - Measles. 428 surgery team
6- Albumin containing solutions: • Used as plasma expander in severe hemorrhage while waiting for blood. • Also used to maintain plasma albumin levels in: • - Liver failure. • - Malnutrition. • - Protein losing states. 428 surgery team
Blood Types: • O Rh-positive 38% • O Rh-negative 7% universal donor • A Rh-positive 34% • A Rh-negative 6% • B Rh-positive 9% • B Rh-negative 2% • AB Rh-positive 3% universal recipient • AB Rh-negative 1% 428 surgery team
INDICATIONS FOR BLOOD TRANSFUSION • Massive blood loss – acute blood loss. • Different types of anaemia – chronic anemias. • Haemophilia & other clotting factor deficiency – chronic deficiency of any blood component. • Cancer patients • For surgeries 428 surgery team

DIFFERENT BLOOD GROUPS 428 surgery team
RHESUS MONKEYS 428 surgery team
BLOOD DONATION CRITERIA • Good general condition. • Age: 18 to 60 years. • Weight- >45kg for 350ml, >55kg for 450ml. • BP: syst. 100-180mmHg diast. 50-100mmHg. • Pulse: 60 to 100beats/min. 428 surgery team
BLOOD DONATION CRITERIA • Temp. >37.5deg.C • Hb. >12.5gm% • Jaundice • Malaria • High risk behaviour • Pregnancy 428 surgery team
BLOOD DONATION CRITERIA • Surgeries • Last blood donation • Tattooing • Chronic diseases • Last blood transfusion 428 surgery team
INSTRUCTIONS TO DONOR AFTER DONATION More fluids than usual. Do not remain hungry. Do not smoke for 1hour. Remove bandage after 6 hours. If bleeding from puncture site, apply pressure. If feeling faint/dizzy, lie down. 428 surgery team
MISCONCEPTIONS/ REASONS FOR NOT DONATING BLOOD • Fear of contracting some disease • I do not have enough blood/ I will become weak. • I am too old • I am too busy. 428 surgery team
REASONS TO DONATE BLOOD • New blood formation . • Regular health check up. • Blood investigations done. • Satisfaction of noble work. 428 surgery team
TESTS DONE IN BLOOD BANK • Blood grouping & Rh typing • Cross matching • Tests for irregular antibodies • HBsAg test& Anti-HBc • HCV test • HIV test (HIV1 & HIV2) • Test for syphilis • Test for malaria 428 surgery team
Screening tests on donors’ blood: • - Hepatitis B surface antigen (HBsAg). • - Hepatitis B core antibody (anti-HBc). • - Hepatitis C virus antibody (anti-HCV). • - HIV-1 and HIV-2 antibody (anti-HIV-1 and anti-HIV-2). • - HTLV-I and HTLV-II antibody (anti-HTLV-I and anti-HTLV-II). • Serologic test for syphilis. • Prerequisites: • Take samples for full blood count (FBC), serum iron or ferritin B, and folate levels. • Cross match. • Choose the appropriate blood group in emergency. • Appropriate IV access. 428 surgery team
MISMATCHED TRANSFUSION Group A + Group B = Clumping of RBCs + 428 surgery team
AUTOLOGOUS DONATION • Self help is the best help. • Planned gynaecological, orthopedic, plastic general surgeries • Individuals with rare blood groups/ irregular antibodies/ infectious disease positive. 428 surgery team
AUTOLOGOUS DONATIONAdvantages • Safest blood. • Easy availability • No risk of TTDs • Best option in patients with irregular antibodies, rare blood groups, infectious disease positive. • Blood scarcity can be reduced to someextent. 428 surgery team
Blood Transfusion: • Autologous: • Blood donor and transfusion recipient are the same in order to avoid blood borne diseases or infections. • Four types: • 1. Preoperative donations: • - Donating the patient’s own blood before surgery. • - The blood bank draws the patient’s blood and stores it until he/she needs it during or after surgery. • - Only for elective surgery. • 2. Preoperative hemodilution: • - Immediately before surgery, some of the patient’s blood is taken and replace with IV fluids, i.e. normal saline. • - Only for elective surgeries. 428 surgery team
3. Perioperative (intraoperative) collection: • Recycling the patient’s blood during surgery. • Blood lost during surgery is filtered, and put back into the patient’s body during surgery. • Can be done in emergency and elective surgeries. • 4. Postoperative collection: • - Recycling the patient’s blood after surgery. • Blood lost after surgery is collected, filtered and returned to the patient’s body. • Can be done in emergency and elective surgeries. 428 surgery team
