Sometimes, a patient may lose blood as a result of a surgery or they have lost blood already by the time they are admitted to the hospital. If someone loses too much blood, the hospital will have to take donated blood and give the patient a blood transfusion.
Unfortunately, there have been complications with blood transfusions in the past. One is that the blood is tainted with a disease. Now the patient has a disease. Another could be hypotension or shock due to a foreign substance being put into their bodies.
However, the biggest problem of a transfusion having a deadly reaction to a patient is based on a clerical error. This means that the nurse misread or made a mistake in the transfusion and it caused problems for the patient leading to his or her death.
A clerical error.-the most common cause of fatalities related to transfusion reactions result from abo-incompatible transfusion related to clerical error. most such reactions occur if a type o person receives type a red cells owing to a clerical error that occurs either at the time the blood sample was drawn, during processing in the laboratory, or at the time a unit is administered. the importance of extremely careful labeling, transfer, and handling of specimens and of cross-matched blood products cannot be overemphasized. allergic and other reactions are common but rarely fatal. the transmission of bacterial organisms (e.g., staphylococcus aureus) has been reported especially with platelet concentrates maintained at or near room temperature. fortunately, such reactions are rare.
