How safe is blood transfusion in humans?

Blood Transfusion - Sriramakrishnahospital

A blood transfusion could be a common medical treatment that includes accepting given blood through a little tube embedded into a vein in your arm. This possibly life-saving operation can help within the substitution of blood misplaced as a result of surgery or harm. A hemoglobin transfusion can also help if an infection inhibits your body from properly producing blood or any of the components of your blood.

The majority of blood transfusions go off without any complications. In case issues do emerge, they are as a rule minor.

Why is blood transfusion performed?

Generally, blood transfusion is recommended for people who undergo surgeries, sustained injuries, and any bleeding disorders. 

Blood contains several components, that include:

Red Blood Cells: Transports oxygen and aids in waste removal.

White Blood Cells: Aids in protecting the body from infections.

Plasma: The liquid component of the body

Platelets: Aids in the clotting of the blood.

A transfusion replaces the component or parts of your blood that you don’t have, with red blood cells being the most common. Whole blood, which contains all of the components, is also available, but whole blood transfusions are uncommon.

How does the transfusion work?

Until they are needed, the donated blood or blood components are kept in special medical bags. Your healthcare provider connects the required blood bag to a tubing-based intravenous line. The blood or blood components are given into your circulatory system with a needle put into one of your veins at the end of the tubing.

In order to ensure the safety of hemoglobin transfusion, several precautions and criteria must be followed. The procedure for acquiring and testing donor blood for transfusion is briefed below.

  • Before being eligible to donate blood for transfusion, the donor must complete a questionnaire outlining any history of infectious diseases or other medical difficulties.
  • The hemoglobin level of the donor is measured.
  • After the blood is drawn, it is tested and screened for infectious agents such as HIV and hepatitis.
  • To ensure compatibility, the donor’s blood is cross-matched with a sample of the patient’s blood. The antigen profile of a person’s red blood cells determines their blood group. The ABO and Rh antigens are the most essential antigens in blood type. 
  • Every person has an ABO blood type (blood group A, B, AB, or O), which indicates whether their red blood cells express antigen A, antigen B, both antigens, or neither antigen. 
  • The Rh antigen is also either positive or negative in each individual. These antigens can be combined to create eight different blood types.
  • Only if the patient truly stands to benefit from the surgery is he or she considered for a leukemia blood transfusion. A complete blood count is used to determine the quantities of various blood components such as red blood cells, white blood cells, and platelets.
  • Testing for coagulation (clotting) is also done.
  • Blood is transfused via tubing linked to a needle or catheter that supplies the vein.
  • The amount of blood transfused is determined by the demands of each patient.
  • Vital indicators such as temperature, heart rate, and blood pressure are carefully monitored during a blood transfusion.
  • Some patients may develop a sudden fever during or shortly after the transfusion, which can be treated with over-the-counter fever medicine. A typical reaction to the white blood cells in donated blood is a fever.

Benefits of Blood Transfusion:

Blood is the main component of the human body, by donating you can help anyone who is in need of blood and save their life from danger.
