Blood transfusions: What to know

Jump to navigation. Whole blood donations are separated into specific cellular red blood cells and platelets and plasma components. Transfusing the appropriate blood component to effectively provide for the clinical needs of patients optimizes use of donated blood. This chapter describes the manufacturing process for the most commonly prepared blood components:. Brief descriptions of the indications, contraindications, storage and transportation requirements, dose, administration and available alternatives are included in the sections below. Further information may be found in other chapters of this Guide as indicated within the different sections.

Blood transfusions work to replace blood that is lost due to injury or surgery. People can also get blood transfusions to treat certain medical conditions. This article will outline what a blood transfusion is, when they are necessary, and what to expect during the procedure. A blood transfusion is a procedure that restores blood to the body. A healthcare professional will pass blood through a rubber tube into a vein using a needle or thin tube.

Blood transfusions save millions of lives in the United States every year. People usually donate whole blood — blood taken right out of a vein through a needle. This whole blood may be called a unit or pint of blood, and equals about milliliters or But whole blood is rarely given as a transfusion. Blood has many parts called components , and each one does a different job. Whole blood is usually separated into red blood cells, platelets, and plasma. Plasma can be further separated into clotting factors and certain proteins.

Transfusions are given to increase the blood's ability to carry oxygen, restore the amount of blood in the body blood volume , and correct clotting problems. Transfusions are usually safe, but sometimes people have adverse reactions. To minimize the chance of an adverse reaction during a transfusion, health care practitioners take several precautions. Before starting the transfusion, usually a few hours or even a few days beforehand, the person is cross-matched with the donor blood not done for transfusions of plasma or platelets. After double-checking labels on the bags of blood that are about to be given to ensure the units are intended for that recipient, the health care practitioner gives the blood to the recipient slowly, generally over 1 to 4 hours for each unit of blood.

The amount and part of the blood transfused depends on what the patient needs. A CBC measures the levels of components within the blood such as red blood cells, white blood cells, and platelets. Tests of clotting coagulation may also be done if abnormal bleeding is a problem.

The Center for Biologics Evaluation and Research CBER regulates the collection of blood and blood components used for transfusion or for the manufacture of pharmaceuticals derived from blood and blood components, such as clotting factors, and establishes standards for the products themselves.

Blood Transfusions for People with Cancer

A more recent article on blood product transfusion in adults is available. Red blood cell transfusions are used to treat hemorrhage and to improve oxygen delivery to tissues. Transfusion of red blood cells should be based on the patient's clinical condition. Indications for transfusion include symptomatic anemia causing shortness of breath, dizziness, congestive heart failure, and decreased exercise tolerance , acute sickle cell crisis, and acute blood loss of more than 30 percent of blood volume.

Blood transfusions can be lifesaving. If the blood type is not a match, you can experience a transfusion reaction. These reactions are rare, but they can be harmful to your kidneys and lungs. In some cases they can be life threatening. This can be due to:.

Blood transfusions: What to know

During the MTP, blood products are being given so rapidly that it's impossible to adjust product administration according to laboratory values usually by the time a laboratory test results are available, they are already obsolete.
