A blood transfusion is the delivery of blood products through a vein. The blood products may be red cells, white cells, platelets, clotting factors, plasma, or whole blood. The blood may come from an unrelated or related donor, or it may have been taken from the recipient and stored in advance.

Reasons for Procedure

A blood transfusion should help increase your level of blood cells or other specific blood products. It may be needed if you have:

  • Blood and fluid loss due to injury, surgery, or disease
  • Severe anemia]]>
  • Bleeding disorders, such as ]]>von Willebrand's disease]]> or ]]>hemophilia]]>
  • Poor immune system
  • ]]>Leukemia]]>
  • Diseases that result in destruction of blood cells or bone marrow
  • Side effects of certain medicines (eg, chemotherapy for cancer)

Possible Complications

Your doctor will review any possible complications with you. Complications from a blood transfusion are rare but may include:

  • Allergic reactions due to the mismatching of blood types can occur but are very rare.
  • Certain infections, such as hepatitis or ]]>HIV]]> , can be passed on during blood transfusions, but this is very rare. Many steps and tests are done to thoroughly check donated blood for such infections before anyone is allowed to receive it.


What to Expect

Prior to Procedure

  • You will have a blood test to determine your specific blood type. The donor blood will be carefully matched to your blood type.
  • You will also be given a physical exam. Your vital signs (eg, temperature, heart rate, breathing rate, and blood pressure) will be recorded.
  • You may be given Tylenol]]> and ]]>Benadryl]]> before you receive a transfusion. These drugs will help reduce any minor allergic reactions.

Description of the Procedure

You will be asked to sit in a comfortable chair. A bag containing the blood product will be hung nearby. An IV needle will be placed into a vein in your hand or arm. The blood product will drip slowly from the bag through a tube into your vein. Once the bag of blood product is empty, the needle in your arm will be removed.

Throughout the transfusion, your vital signs will be checked regularly. You will also be asked about pain, itching, or discomfort of any sort. Most reactions occur early in a blood transfusion, so you will be monitored more closely during the first 15 minutes.

How Long Will It Take?

About 2–4 hours

Will It Hurt?

The placement of the IV needle is mildly painful. Once the needle is in place, it should not cause pain.
