Theme: Blood transfusion fears. - If you are planning to have a blood transfusion, you may be concerned about the risks associated with accepting donated blood. While the risks are minimal, and the supply of blood in the United States is very safe, there are always risks associated with a transfusion.
Extensive screening helps prevent the transmission of infectious diseases; however, there are additional risks that one must consider when considering having a blood transfusion. These risks, some of which are serious, must be weighed against the health concerns that can be caused by a lack of blood or blood cells, such as anemia and hypovolemia. - Extensive screening helps prevent the transmission of infectious diseases; however, there are additional risks that one must consider when considering having a blood transfusion.

Hemolytic Reaction to Blood Transfusion - A hemolytic reaction is a reaction to the administration of donor blood. Steps are taken to prevent severe reactions, starting with lab procedures that help prevent the administration of blood likely to cause a problem. A hemolytic reaction can be life-threatening, and the transfusion will not continue if a reaction occurs.
A hemolytic reaction occurs when the immune system of the patient receiving the blood transfusion destroys the transfused red blood cells. During the administration, additional procedures may be used to reduce the likelihood of a reaction to a transfusion, including giving blood slowly, so that any reaction can be noted prior to a substantial amount of blood being given, and closely monitoring for any signs of difficulty. - A hemolytic reaction occurs when the immune system of the patient receiving the blood transfusion destroys the transfused red blood cells.

The severity of the reaction and the consequences of not giving the blood will determine if the blood will continue to be given or if the transfusion will be stopped. Benadryl, Tylenol or other pain medications, antihistamines, or steroids may be given to stop or reduce a reaction to a transfusion. - The severity of the reaction and the consequences of not giving the blood will determine if the blood will continue to be given or if the transfusion will be stopped.

In some cases, a patient who is known to have a reaction to blood transfusions is given a transfusion anyway. This is because the risk of the reaction is lower than the risks associated with untreated bleeding - In some cases, a patient who is known to have a reaction to blood transfusions is given a transfusion anyway.

Nausea - Nausea
- Fever: A sudden fever immediately after the transfusion of blood begins may be a sign of an impending allergic reaction. The patient's temperature should always be taken prior to a transfusion.
- Anxiety: A patient may have a feeling of impending doom or fear when an allergic reaction is about to happen.
Tachycardia: A faster than normal heart rate may happen before a reaction, for this reason, vital signs are typically taken immediately prior to the administration of blood. Tachycardia: A faster than normal heart rate may happen before a reaction, for this reason, vital signs are typically taken immediately prior to the administration of blood. - Hypotension: Blood pressure is lower than normal in some cases of a reaction to blood.
Pain: Chest pain and back pain are less common symptoms of a reaction. Pain: Chest pain and back pain are less common symptoms of a reaction. Dyspnea: Difficulty breathing can appear in severe reactions. - Kidney dysfunction: The kidneys can have difficulty filtering blood due to the number of dead blood cells attacked by the immune system.
Bloody Urine: Along with kidney dysfunction, the patient's urine can show evidence of blood passed by the kidneys. - Bloody Urine: Along with kidney dysfunction, the patient's urine can show evidence of blood passed by the kidneys.
- Flank pain: Kidney dysfunction can be painful and presents as flank pain.
- Increased Risk of Infection: If your blood donor was ill when they donated or became ill shortly thereafter, your risk of infection is increased. Your risk is higher if your immune system is compromised or if you are extremely ill.
- Death: Extremely rare, but possible, if a hemolytic reaction is severe enough.
