Acute transfusion reaction

Stop the transfusion, assess physiological danger and preserve the evidence needed for rapid investigation and safe treatment.

PAUSE BEFORE USING

This is an educational summary, not a point-of-care protocol. Follow current local emergency and medicines guidance and seek senior/specialist support.

FICTIONAL SCENARIO

A fictional 52-year-old develops rigors, breathlessness, lumbar pain and hypotension shortly after a red-cell transfusion begins.

01 · RECOGNISE

Frame the danger first.

  • New fever, rigors, rash, dyspnoea, pain or haemodynamic change during transfusion requires immediate assessment.
  • Consider haemolysis, anaphylaxis, bacterial contamination, lung injury and circulatory overload.
  • Check patient identity, component details and timing while resuscitation proceeds.
02 · FIRST PRIORITIES

Act, escalate, reassess.

  1. Stop the transfusion, call for help and assess using ABCDE; maintain intravenous access with locally approved fluid and equipment.
  2. Recheck identity and clerical details and notify the transfusion laboratory urgently.
  3. Follow the local acute-transfusion-reaction pathway for samples, cultures, component return and treatment.
  4. Document the reaction, response and specialist advice before any decision about further transfusion.
03 · ESCALATE NOW IF

Red flags that change pace.

  • Shock, airway swelling, bronchospasm or severe hypoxaemia
  • Chest or loin pain, haemoglobinuria, bleeding or suspected incompatible transfusion
  • High fever, rigors or concern for bacterial contamination
04 · COMMON ERRORS

What makes care less safe.

  • Restarting a transfusion before the reaction is characterised
  • Discarding the component or administration set
  • Treating symptoms without completing identity and laboratory checks
05 · STRUCTURED HANDOVER

Say the concern plainly.

Acute transfusion reaction after [component/volume/time], with [symptoms and observations]. The transfusion stopped at [time], identity checks are [status] and the laboratory has been contacted. I need urgent senior/transfusion advice for [specific concern].
