Precautions and Adverse Reactions During Blood Transfusion
Lung injury
Another very rare reaction, called transfusion-related acute lung injury (TRALI), is caused by antibodies in the donor's plasma. This reaction may cause serious breathing difficulties. This complication is the second most common cause of transfusion-related death. It occurs in 1 in 5,000 to 1 in 10,000 transfusions, but many cases are mild and so may not be diagnosed. Most people with mild to moderate lung injuries are given oxygen and other treatments that aim to support breathing until the lungs heal. Using plasma donated by men reduces the risk of having this reaction.
