monitor the treatment
The blood given by transfusion must be matched with the recipient's blood type. Incompatible blood types can cause a serious adverse reaction (transfusion reaction). Blood is introduced slowly by gravity flow directly into the veins
Sometimes problems occur with a blood transfusion, but that is supposed to be rare. Some people can have an allergic reaction to the transfusion.
Every blood transfusion carries the risk of allergic reaction, to anaphylactic shock, even if blood type is perfectly matched. If medication was also infused along with the blood, and the patient had an allergic reaction, it would be impossible to tell which sustance was causing the reaction: the blood? or the medication? Remember that every transfusion reaction can be deadly. As well, some meds may break down blood components. Therefore, never inject IV meds into a transfusion tubing or combine medications into a blood transfusion set.
Acute immune hemolytic reaction
Risks associated with autologous blood transfusion include transfusion reaction if an allogeneic blood transfusion was inadvertently given and transmission of infectious agents if the blood became contaminated.
An acute febrile reaction is the most common adverse reaction to a blood transfusion. This is typically treated with tylenol.
These complications may include an acute hemolytic transfusion reaction (AHTR), which is most commonly caused by ABO incompatibility. The patient may complain of pain, difficult breathing, fever and chills, facial flushing, and nausea.
True.
"Adverse" means harmful or unfavorable, and transfusion probably refers to blood transfusion--so a negative reaction to a blood transfusion? The term is very vague; without context it's hard to say exactly what this would mean.
A reaction to the wrong type could be fatal.
If the blood types do not match, you run the risk of toxicity.
Asssuming the correctly-typed blood was administered, the most common type of infusion reaction is fever, often pre-treated with Tylenol/Benadryl before the transfusion is given.
