What are the signs of blood transfusion reaction?
Reaction of blood transfusion is a serious complication resulting from blood or blood products. The blood donor and the recipient's blood must exactly match the blood type and factor of RH (rhesus). Non -agreement can cause red blood cells to tear and clump together in a process called hemolysis. This can cause an acute haemolytic reaction that inhibits blood circulation in the body. A bacterium or a virus present in a donated blood can also cause an unfavorable reaction. Some people can become dizziness or feel weak. A person may feel pain on the side of the body or rear, in an approximate place of the kidneys. Pain can follow blood in urine or dark urine. If the blood transfusion reaction is caused by an allergic reaction, itching red rashes may appear on the body. Intravenous (IV) fluids can be administered to dilute blood and promote easier blood circulation through the body. Fluid administration can also prevent kidneys after response to blood or blood products. Some people may have hivesFrom an allergic reaction to blood and a dose of antihistamines, it can alleviate related itching and swelling.
Reaction of blood transfusion often occurs within moments from the beginning of the transfusion process. If the transfusion is still ongoing when the symptoms of undesirable reactions begin, the transfusion will be interrupted immediately. The donor's blood will be rescued and tested for the presence of antibodies, bacteria or virus.
The less serious transfusion reaction of the blood is called a nehemolytic febrile reaction. It is the most common undesirable response to blood transfusion. The patient is likely to have a fever and will feel uncomfortable until the reaction retreats. This condition usually does not require any treatment, although the patient will be carefully observed in the hospital. A delayed transfusion reaction may take several days and may include liver problems such as jaundice.
people who had previous blood transfusions have the highest risk of developing an allergic reaction to the donorOvská blood. This is because various antibodies from the blood of the donor accumulate in the recipient's blood over time. The antibody concentration increases the unfavorable response to the new blood introduced into the body more likely.
