THE INSIDE STORY OF BLOOD TRANSFUSION DR.MOHAMED BILAL DELVI ASSISTANT PROFESSOR DEPT OF ANAESTHESIA COLLEGE OF MEDICINE KSU. Done by : 428 surgery team 1428 surgery team
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 2428 surgery team
Blood is an amazing fluid! Keeps us warm Provides nutrients for cells, tissues and organs Removes waste products from various sites 3428 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% 4428 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. 5

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 8428 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 9428 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 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 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 surgery team

Blood Transfusion: A.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 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 surgery team
B. Allogenic: Blood transfused to someone other than the donor. Practical tips: Give one unit over 4 hours. Use blood warmer if patient is hypothermic. Give 40 mg IV frusemide in between each unit. If possible, give transfusions early in the day. Check hemoglobin hours after transfusion surgery team
Complications of Transfusion: Transfusion reaction. Transmission of infections. Hyperkalemia. Hypocalcemia. Thrombocytopenia. Depletion of clotting factors. Transfusion reaction: Fever. Urticarial rash. Agitation. Chest or abdominal pain. Hypotension. Wheezing. Severe back pain surgery team
Management of transfusion reaction: Stop transfusion. Return the remaining blood to lab. Give 100 mg of hydrocortisone and 10 mg chlorpheniramine IV. Recheck the cross matches. Monitor vital signs. Monitor urine output. Inform your senior colleague surgery team
In emergencies, the Rh – person can receive few units of Rh + blood if he/she has no anti-D antibodies. They are generally elderly male patients.

Appropriateness of transfusion May be life-saving May have acute or delayed complications Puts patient at risk unnecessarily ‘ The transfusion of safe blood products to treat any condition leading to significant morbidity or mortality, that cannot be managed by any other means’ surgery team
Inappropriateness of transfusion Giving blood products for conditions that can otherwise be treated e.g. anaemia Using blood products when other fluids work just as well Blood is often unnecessarily given to raise a patient’s haemoglobin level before surgery or to allow earlier discharge from hospital. These are rarely valid reasons for transfusion surgery team
Inappropriateness of Transfusion Patients’ transfusion requirements can often be minimized by good anaesthetic and surgical management. Blood not needed exposes patient unnecessarily Blood is an expensive, scarce resource. Unnecessary transfusions may cause a shortage of blood products for patients in real need surgery team

Problems faced Too few donors Lack of equipment Insufficient products Insufficient reagent Infectious disease testing surgery team
Recommendations Increase public awareness about need for blood and hence the number of voluntary donors Continue to encourage relatives to donate for patients* Increase the number of mobile clinics Extend the opening hours for blood collecting surgery team
Recommendations Management of stocks of blood and blood products Maintenance and replacement of equipment On-going training of Haematology Lab Staff Better management of reagents for- infectious disease testing, antigens etc. Improved record keeping Move to electronic record keeping surgery team
Recommendations View to reduce the need for allogeneic transfusions Autologous transfusions Blood saving devices in OR (operating room) Acute normovolemic haemodilution Oxygen carrying compounds surgery team
