Blood transfusion: From risk factors to care, all you need to know about the procedure
Two patients died at a hospital in Odisha’s Keonjhar drict allegedly due to wrong blood group transfusion. A probe has been ordered into the incident for the alleged negligence on the part of a hospital attendant and two technicians of the blood bank, according to reports.
As such, here are a few important things to understand about blood transfusion practices.
Why are blood transfusions done?
Blood transfusion helps replace blood lost to injury or during surgery, or any such medical conditions. “Generally, RBC (red blood cell) transfusions are performed with the intention to increase arterial oxygen content and thus oxygen delivery to the tissues,” according to a study published in National Center for Biotechnology Information (NCBI).Best of Express PremiumPremiumPremiumPremiumPremium
How is transfusion carried out?
All tests are carried out to ascertain the compatibility of the transfused blood. During blood transfusion, a small needle is placed in the vein of your arm through which blood is transfused. Medical staff monitors all the vital parameters when transfusion is being done, said Dr Manjusha Agarwal, Senior Consultant-Internal Medicine at Global Hospital Parel Mumbai. She added that it usually it takes “upto 4 hours to complete a transfusion, in emergencies, it can be transfused even at a faster rate.”

Risk factors
The critical thing to understand is that “if you receive blood that is not compatible with your blood, your body produces antibodies to destroy the donor’s blood cells. This is called transfusion reaction”, said the expert.
According to Dr Agarwal, transfusion reaction can be in the form of fever, hives and itching. “In severe cases, lung injury can happen. Bacteria present in donors can cause infection in the recipient. Acute kidney injury due to hemolytic reaction can also occur,” Dr Manjusha explained.
How to prevent human error when receiving blood
According to Dr Sangeeta Agarwal, senior consultant, Department of Transfusion Medicine, Fortis Memorial Research Institute, Gurugram,
*Double check the blood details before every transfusion retesting.*Make sure the recipient and donor details are actualities – they are proved with evidence.*Correctly labeling items in storage.
Post-transfusion care
Post-transfusion, there may be an ache in the arm or bruising at the site of transfusion. “There is a very small risk of delayed reaction which can cause nausea, swelling, jaundice, or itchy rash. Please consult your doctor if you feel unwell post-transfusion,” advised Dr Manjusha .
