Blood transfusion is a medical treatment to replace the blood or parts of blood that your child's body has lost. The blood goes through a tube from a bag to an intravenous (IV) catheter and into your child's vein.
Your child may need a blood transfusion after losing blood from an injury, a major surgery, an illness that causes bleeding, or an illness that destroys blood cells.
Transfusions are also used to give your child the parts of blood—such as platelets, plasma, or substances that cause clotting—that your child's body needs to fight an illness.
Before your child receives a blood transfusion, his or her blood is tested to find out what type it is. Blood or blood parts that are a match with your child's blood type are ordered by the doctor. Blood is typed as A, B, AB, or O. It is also typed as Rh-positive or Rh-negative.
Your child's blood is also screened to look for antibodies that might react with the blood that is given to your child. The blood your child gets is checked and rechecked to make sure that it's the right type.
A sample of your child's blood is mixed with a sample of the blood he or she will receive. This is done to check for problems. Before giving the transfusion, a doctor or nurse will look at the label on the package of blood and compare it to your child's hospital ID bracelet and medical records. The transfusion begins only when all agree that this is the correct blood and that your child is the correct person to receive it.
To receive the transfusion, your child will have an intravenous (IV) catheter inserted into a vein. To place the catheter, the doctor or nurse will use a small needle, which can cause a little pain. To reduce the pain, the nurse may first use a cream or other method to numb your child's skin.
A tube connects the catheter to the bag containing the blood, which is placed higher than your child's body. The blood then flows slowly into your child's vein. A doctor or nurse will check your child several times during the transfusion to watch for a reaction or other problems.
