Slide 2-

Dr. Salwa Hindawi Introduction Blood Transfusion is not without hazards you should weigh the risk against benefit use of right products to the right patient at the right time
Slide 3-

Dr. Salwa Hindawi The risks associated with transfusion can be reduced by: - Effective blood donor selection. - Screening for TTI in the blood donor population. high quality blood grouping, compatibility testing. - Component separation and storage. - Appropriate clinical use of blood and blood products. - Quality assurance Donor Patient

Slide 6-

Dr. Salwa Hindawi Principles of Clinical Transfusion Practices Avoid blood transfusion Transfusion is only one part of the patient’s management. Prevention and early diagnosis and treatment of Anemia & underlying condition Use of alternative to transfusion. eg. IV fluids Good anesthetic and surgical management to minimized blood loss.
Slide 7-

Dr. Salwa Hindawi Prescribing should be based on national guidelines on the clinical use of blood taking individual patient needs into account. Hb level should not be the sole deciding Factor Clinical evaluation is important
Slide 8-

Dr. Salwa Hindawi Consent form to be obtained from the patient before transfusion. The clinician should record the reason for transfusion clearly. A trained person should monitor the transfused patient and if any adverse effects occur respond immediately.
Slide 9-

Dr. Salwa Hindawi Informed consent Patient should be informed that transfusion of blood or blood component is a possible element of the planned medical or surgical intervention patient should be informed about the risks, benefits and available alternative Consent form is a doctor responsibility

Dr. Salwa Hindawi WHEN WE SHOULD TRANSFUSE BLOOD ?&WHAT BLOOD COMPONENT SHOULD BE TRANSFUSED ?
Slide 11-

Dr. Salwa Hindawi TO TRANSFUSE BLOOD WHEN NECESSARY
Slide 12-

Dr. Salwa Hindawi The lowest threshold for transfusion of components are: Hb level of 6-7g/dl. FFP threshold PT & PTT 1.5 times the upper limit of the normal range. Platelet threshold of: 10 000/µl- 20 000/µl for prophylactic transfusion. Consider: Clinical judgment Triggers of Component Transfusion
Slide 13-

Dr. Salwa Hindawi Invasive or surgical procedures: 20 000/µl for BMA and Biopsy 50 000/µl for surgery, massive transfusion, Liver cirrhosis. 100 000/µl for surgery to brain or eye.

Slide 14-

Dr. Salwa Hindawi Administration of blood components Pretransfusion : Recipient identification: The name and identification number on the patient’s identification band must be identical with the name and number attached to the unit. Unit identification: The unit identification number on the blood container, the transfusion form, and the tag attached to the unit (if not the same as the latter) must agree.

Dr. Salwa Hindawi MSBOS is a table of elective surgical procedures that lists the number of units of blood routinely cross-matched pre-operative. The ideal value for cross matched to transfused blood, C:T ratio is 1:1 . An acceptable value is 3:1 - 2:1 which corresponds to a blood usage of 30-50%. Maximum Surgical Blood Ordering Schedule (MSBOS)
Slide 21-

Dr. Salwa Hindawi Type and Screen (T & S) an ABO and Rh type and an antibody screen and antibody identification are done when the patient is admitted. only testing necessary if low probability of transfusion
Slide 22-

Dr. Salwa Hindawi Type and Cross (T & C) includes an ABO and Rh type and antibody screen and antibody identification. in addition includes a crossmatch where specific units of blood are held back for up to three days for a particular patient. for a high probability of transfusion.
Slide 23-

Dr. Salwa Hindawi Crossmatch to Transfusion ratio (C:T ratio) blood is used more efficiently when the number of units set aside for a particular patient (crossmatched) are actually transfused. C:T ratio is less than 2:1 when a patient does not need blood, it is good practice to get a T& S but not a T & C
Slide 24-

Dr. Salwa Hindawi Incompatible Blood TransfusionClinical Setting A patient, lacking compatible blood, experiencing life- threatening, rapid blood loss or hemolysis, in whom the need for blood replacement is immediate or urgent.
Slide 25-

Dr. Salwa Hindawi Rarely, facility may lack ABO compatible blood * Pan-agglutinin (autoantibody) may be present * Alloantibody to high frequency antigen may be present* Alloantibodies to multiple antigens may be present
Slide 26-

Dr. Salwa Hindawi Guidelines for Transfusing Incompatible Red Blood Cells If patient condition permits, start the transfusion slowly at one ml per minute for the first 15 minutes. Observe the patient constantly for symptoms and signs of a reaction. Take vital signs prior to starting transfusion, whenever a reaction is suspected or, in the absence of a reaction after first 15 minutes, after 30 minutes, and after completion of transfusion.
Slide 27-

Dr. Salwa Hindawi If there is evidence of a transfusion reaction Symptoms include fever, pain, apprehension, chills, sweating, tachycardia, or fall in blood pressure. STOP the transfusion immediately, maintaining the IV with 0.9% saline. Document vital signs at least every 15 minutes throughout the reaction.
Slide 28-

Dr. Salwa Hindawi If patient condition warrants immediate transfusion: Begin another unit of Red Blood Cells per physician order. The new unit also is likely to test as incompatible, but may be tolerated better. If further transfusions can be delayed, follow the transfusion reaction policy and resume transfusion after evaluation is complete.
Slide 29-

Dr. Salwa Hindawi If no symptoms or signs of transfusion reaction are noted after 30 minutes Proceed with the transfusion and monitor the patient for usual transfusion practices. Repeat the entire process for each incompatible Red Blood Cell transfused.
