Verify that an order for the transfusion exists.
Conduct a thorough physical assessment of the patient (including vital signs) to help identify later changes.
Teach the patient about the procedure’s associated risks and benefits, what to expect during the transfusion, signs and symptoms of a reaction, and when and how to call for assistance.
Patients needing blood transfusions should be told about the risks and benefits of the procedure so that they can give informed consent before it is undertaken.
Obtain informed consent.
Check for appropriate and patent vascular access.
Make sure the necessary equipment is at hand for administering the blood product and managing a reaction, such as an additional free intravenous (IV) line for normal saline solution, oxygen, suction, and a hypersensitivity kit.
The nurse should be familiar with the specific product to be transfused, the appropriate administration rate, and required patient monitoring. Be aware that the type of blood product and the
patient’s condition usually dictate the infusion rate. For example, blood must be infused faster in a trauma victim who is rapidly losing blood than in a 75-year-old patient with heart failure, who may not be able to tolerate rapid infusion.
Know what personnel will be available in the event of a reaction, and know how to contact them. Resources should include the on-call physician and a blood bank representative.
Before hanging the blood product, thoroughly double-check the patient’s identification and verify the actual product. Check the unit to be transfused against patient identifiers, per facility policy. Have a second licensed health care provider double check the patient’s identifying information, type and cross-match data, patient blood group and Rh factor, type and Rh factor of blood to be infused, blood bank identifying information, and expiration date of blood product.
Infuse the blood product with normal saline solution only, using filtered tubing.
Premedication
Premedication may be prescribed. To help prevent immunologic transfusion reactions, the physician may order such medications as acetaminophen and diphenhydramine before the transfusion begins to prevent fever and histamine release. Febrile nonhemolytic transfusion reactions seem to be linked to blood components, such as platelets or fresh frozen plasma, as opposed to packed red blood cells; thus, premedication may be indicated for patients who will receive these products. Such reactions may be mediated by donor leukocytes in the plasma, causing allosensitization to human leukocyte antigens. Cytokine generation and accumulation during blood component storage may play a contributing role.
Time Frame for Administration
The nurse must confirm the window of time during which the product must be transfused, starting from when the product arrives from the blood bank to when the infusion must be completed. Failing to adhere to these time guidelines increases the risk of such complications as bacterial contamination.
Before administering the blood transfusion, the nurse should clearly document that the product matched the label on the blood product and that the following were verified:
patient’s name
patient’s identification number
patient’s blood group or type
patient’s and donor’s Rh factor
crossmatch data
blood bank identification number
expiration date of the product
In addition, the nurse should document that the blood or blood component and the patient were matched by two licensed health care professionals at the patient’s bedside according to facility policy, that both of the health care professionals signed the slip that came with the blood, and that both of the health care professionals also verified that the information is correct.
When the nurse has determined that all the information is correct and matches, the consent form has been signed, and the patient’s vital signs are within acceptable parameters per the facility’s policy, the nurse may administer the transfusion and document the following on the transfusion record:
date and time that the transfusion was started and completed
name and credentials of the health care professionals who verified the information
total amount of the transfusion (at least two health care professionals, registered nurses, or physicians should check to see if all identifying information of the patient and blood type and blood products are accurate and match)
patient’s vital signs before, during, and after the transfusion, according to facility policy
patient’s response to the transfusion
The minimum standards for monitoring patients who are receiving blood transfusion include the following:
Pulse rate, blood pressure, temperature, and respiratory rate no more than 60 minutes before the blood transfusion is started.
Pulse rate, blood pressure, and temperature 15 minutes after the start of each blood component. If these readings are significantly different from the baseline observations, the respiratory rate should also be included.
Pulse rate, blood pressure, and temperature no more than 60 minutes after the end of the transfusion.
Transfusion reactions can occur immediately, within 24 hours of a transfusion, or more than 24 hours after a transfusion.
Nurses should know the signs of a transfusion reaction, when to report signs, and how and to whom they should be reported.
In the nurse’s notes, provide additional information:
type and gauge of the catheter
infusion device used (if any) and its flow rate
blood-warming unit used (if any)
amount of normal saline solution used (if any)
patient teaching regarding transfusion reaction signs and symptoms
If the patient receives autologous blood, document the amount of blood retrieved and reinfused in the intake and output records. Also, monitor and document laboratory data during and after the autotransfusion as well as the patient’s pretransfusion and posttransfusion vital signs. Pay particular attention to the patient’s coagulation profile, hematocrit and hemoglobin, arterial blood gas, and calcium levels.
