ToggleBLOOD TRANSFUSION
Blood transfusion refers to the intravenous replacement of lost or destroyed blood with compatible human blood.
TYPES OF BLOOD PRODUCTS
1. Whole Blood: Whole blood is indicated to the patient experiencing acute massive loss or hypovolemic shock. Whole blood restores volume and raises hemoglobin count and therefore oxygen capacity.
- Indication: Acute massive blood loss (e.g., trauma) or hypovolemic shock.
- Purpose: Replenishes blood volume, increases hemoglobin count (carrying oxygen), and improves oxygen-carrying capacity.
2. Packed Red Blood Cells (PRBCs): Red blood cells are separated from a unit of whole blood. 80% of plasma is removed leaving packed red blood cells which may be transfused to a patient to increase the number of red blood cells without overloading the circulatory system with fluids. Certain types of anaemia such as aplastic anaemia may be treated by this blood product.
- Indication:
Anemia (including aplastic anemia)
Conditions requiring increased oxygen-carrying capacity without excessive fluid volume.
- Purpose: Increases the number of red blood cells to improve oxygen delivery without overloading the circulatory system.
3. Platelet Concentration: Platelets may be administered to aid homeostasis in patients suffering from thrombocytopenia. Platelets assist in initiating the clotting process and other clotting factors such as prothrombin, fibrinogen and thromboplastin.
- Indication: Thrombocytopenia (low platelet count), leading to bleeding disorders.
- Purpose: Provides platelets to aid in hemostasis (stopping bleeding). Platelets initiate the clotting process, working alongside other clotting factors like prothrombin, fibrinogen, and thromboplastin.
4. Plasma: Plasma is the fluid part of blood after centrifuging in order to remove the red blood cells. Plasma is used to expand blood volume in cases of shock, burns, haemorrhage and while waiting for blood to be cross matched.
- Indication:
Shock (e.g., due to trauma, burns, or hemorrhage).
While awaiting crossmatched blood for transfusion.
Purpose: Expands blood volume, providing essential proteins and clotting factors.
Indications for Blood Transfusion:
1. Severe Anemia:
- Pregnancy
- Sickle Cell Disease
- Complicated Malaria
2. Preoperative: To address low blood volume levels.
3. Severe Burns: To replace lost fluids and proteins.
4. Postoperative: After major surgeries like:
- Laparotomy (abdominal surgery)
- Open reduction of internal fractures
- Total abdominal hysterectomy
5. Trauma: Following road traffic accidents (RTAs) or other injuries.
6. Blood Clotting Factor Deficiencies: To provide missing clotting factors.
7. Specific Types of Anemia: When other treatment options are inadequate.
Note:
- Blood type matching: It’s important to ensure the blood type of the donor matches the recipient to prevent transfusion reactions.
- Rh factor compatibility: Rh factor is another important blood group factor that needs to be considered.
- Crossmatching: A process to further ensure compatibility between donor and recipient blood.
- Potential risks: Blood transfusions can carry risks, including allergic reactions, infections, and transfusion-related acute lung injury (TRALI).
- Alternatives to blood transfusion: Options like erythropoietin (for anemia) and medications to increase platelet production are sometimes available.
REQUIREMENTS
As for intravenous infusion with addition of: –
Top shelf
- Blood giving set with a filter
- Larger needle or cannula
Bottom shelf
- Unit of blood.
- Normal saline.
- Observation chart, fluid balance chart.
- Patients chart with details of transfusion.
- Medicines as prescribed.
Procedure
The technique of transfusion is similar to intravenous infusion.
- On completion of the transfusion the empty bottle must not be washed and should be kept on the ward for 24 hours, in case it is needed for testing in the case of reaction.
- Record the following on the patient’s chart: –
- Date and time of starting and completing the transfusion.
- Number of the blood bottle.
- Amount of blood transfused.
- Names of nurses or doctor who checked the blood and set up the transfusion.
- Patient’s initial response to the transfusion.
- Urinary output
Administer normal saline before and after blood transfusion.
Complications of Blood Transfusion
The following are some of the adverse reactions which may occur during blood transfusion:
1. Allergic Reactions:
- Cause: Hypersensitivity to components within the blood product.
- Signs & Symptoms: Itching, flushing, hives (urticaria), respiratory distress, and anaphylactic shock.
- Management:
Stop the transfusion immediately.
Notify the doctor urgently.
Administer antihistamines if prescribed.
2. Febrile Reaction:
- Cause: Antibodies in the recipient’s blood reacting to donor white blood cells.
- Signs & Symptoms: Fever, chills, and headache during transfusion.
- Management:
Stop the transfusion immediately.
Inform the doctor.
Provide symptomatic relief (extra blankets, prescribed antipyretics).
Reassure the patient.
3. Incompatibility Reaction:
- Cause: Mismatched blood types (e.g., giving type A blood to a type B recipient). This is a serious, potentially life-threatening reaction.
- Signs & Symptoms: Immediate onset of shivering, chills, headache, low back pain, nausea, vomiting, hemoglobinuria (hemoglobin in the urine), and acute renal failure.
- Management:
Stop the transfusion immediately.
Notify the doctor.
Keep the vein open with normal saline.
Treat shock if present.
Return the blood unit to the blood bank for rechecking.
Collect blood samples from the recipient and urine specimen to check for hemoglobinuria.
Administer diuretics as prescribed.
4. Circulatory Overload:
- Cause: Infusion of blood volume faster than the circulatory system can handle.
- Signs & Symptoms: Distended neck veins, shortness of breath (dyspnea), dry cough, and pulmonary edema.
- Management:
Stop the transfusion immediately.
Inform the doctor, who may decide to stop the transfusion completely or slow the infusion rate.
Administer prescribed medications.
Monitor and record vital signs frequently.
5. Pyogenic Reaction:
- Cause: Bacterial contamination of the blood product or transfusion equipment.
- Signs & Symptoms: High fever, chills, nausea, and vomiting.
- Management:
Stop the transfusion immediately.
Provide tepid sponge baths for fever reduction.
Inform the doctor and the blood bank.
Monitor vital signs closely.
Return the blood unit to the blood bank.
Administer antibiotics and antipyretics as prescribed.
6. Transmission of Infectious Diseases:
- Cause: Blood products can potentially transmit diseases like malaria, syphilis, viral hepatitis, and HIV/AIDS.
- Prevention: Careful screening of donor blood is essential to minimize this risk.
THE ROLES OF A NURSE BEFORE, DURING AND AFTER BLOOD TRANSFUSION
Before Blood Transfusion (Nurse’s Interventions)
- Verify Prescription: Ensure that a blood transfusion has been prescribed by the doctor as indicated in the patient’s file.
- Patient Identification: Properly identify the patient to be transfused.
- Explain Procedure: Explain the procedure to the patient to alleviate anxiety.
- Counsel and Educate: Counsel, reassure, and provide health education to the patient and their relatives about the benefits of the blood transfusion.
