Each unit of blood product transfused carries independent TRALI risk
Male-only donor plasma
Observational data from multiple national programs show >50% TRALI incidence reduction
Policy adopted in UK (2003), US (2014), and other countries

What happened to you
You had a serious lung reaction to a blood transfusion called TRALI (Transfusion-Related Acute Lung Injury)
This caused fluid to build up in your lungs making it hard to breathe
This reaction happens when antibodies in the donated blood react with your lungs
It is not your fault and it was not due to an error in giving you blood
Your recovery
Most people fully recover from this reaction within 2 to 4 days
Your lungs should return to normal without permanent damage
A follow-up chest X-ray will confirm your lungs have healed
Important follow-up
Return to your doctor or emergency department within 1-2 weeks
Repeat chest X-ray to confirm the lung changes have resolved
Lung function testing if you still feel short of breath
Tell every healthcare provider about this reaction
You had a serious transfusion reaction called TRALI
It is essential this be documented before any future blood transfusions
Future blood transfusions
You may still require blood transfusions in the future if medically necessary
Special blood products from male donors or pre-screened donors will be used
Always remind your doctors and nurses about this reaction before any transfusion
Return immediately to the emergency department if you experience
Shortness of breath or difficulty breathing
Even mild shortness of breath that is new or worsening
Chest pain or tightness
Any type of chest discomfort
Rapid heart rate or palpitations
Feeling your heart racing or pounding
High fever above 38.5 degrees Celsius
Especially if you are receiving another transfusion
Confusion or reduced consciousness
Any change in mental status
Turning blue around the lips or fingertips
Sign of low oxygen levels
Activity and diet
Rest as needed and gradually increase activity as tolerated
Avoid strenuous exercise until cleared by your doctor
Take short walks and gradually increase distance each day
No specific dietary restrictions
Stay well hydrated unless instructed otherwise
Avoid alcohol during recovery — alcohol can impair lung healing
