Transfusion Reaction Comparison: Hemolytic vs Febrile vs Allergic vs TACO vs TRALI
Five transfusion reactions all start with "stop the transfusion" — but the next intervention is completely different for each. Giving furosemide saves the TACO patient and worsens the TRALI patient. Mixing up hemolytic and febrile reactions delays life-saving treatment for ABO mismatch. The NCLEX expects you to discriminate by symptom cluster, not just react generically.

TRALI
Pathophysiology & risk
- ABO incompatibility, RBC lysis
- Recipient antibodies vs donor WBCs
- Most common reaction
- Reaction to donor plasma proteins
- Volume overload — too much, too fast
- Donor anti-leukocyte antibodies
- Non-cardiogenic pulmonary edema
Signs & symptoms
- ★Flank/back pain, dark urine
- Onset within first 15 min
- Fever, chills
- Fever, chills
- No rash
- Temp ↑ ≥ 1°C, otherwise stable
- Hives, itching, flushing
- Anaphylaxis: wheeze, hypotension
- Dyspnea, crackles, JVD, hypertension
- Peripheral edema
- Dyspnea, hypoxemia, hypotension
- Onset within 6 hr
Diagnostics & labs
- Positive Coombs (DAT), ↓ haptoglobin
- Hemoglobinuria
- Diagnosis of exclusion
- Diagnosed by skin/airway signs
- Check for IgA deficiency
- ★↑ BNP, ↑ PCWP
- CXR edema + cardiomegaly
- ★Normal BNP/PCWP
- CXR infiltrates, normal heart size
Nursing priorities
- Stop the transfusion immediately
- Return bag + tubing to blood bank
- IV fluids to maintain urine output
- Keep IV open with NS
- Stop the transfusion immediately
- Rule out hemolytic first
- Keep IV open with NS
- Return bag + tubing to blood bank
- Stop the transfusion immediately
- Assess airway
- Keep IV open with NS
- Return bag + tubing to blood bank
- Stop the transfusion immediately
- Sit upright
- Give O₂
- Strict I&O
- Keep IV open with NS
- Return bag + tubing to blood bank
- Stop the transfusion immediately
- Give O₂
- Keep IV open with NS
- Return bag + tubing to blood bank
Treatment & meds
- Fluids, vasopressors if shock
- Treat DIC if it develops
- Antipyretic (acetaminophen)
- Diphenhydramine
- Epinephrine IM if anaphylaxis
- ★Furosemide IV
- ★No diuretics (not overload)
- O₂, may need intubation
Prevention / future transfusion
- 2-RN ID check prevents ABO error
- Leukoreduced units
- Premedicate with acetaminophen
- Premedicate with antihistamine
- Washed products if recurrent
- Transfuse slowly
- Diuretic before/between units
- Report for donor workup/deferral
Red flags — escalate
- Progresses to shock + DIC
- Must exclude hemolytic before resuming
- ★Anaphylaxis: airway compromise, shock
- Respiratory failure from overload
- Severe hypoxemia, ARDS
Complications
- Acute kidney injury, DIC, death
- Benign, self-limited
- Anaphylactic shock
- Cardiogenic pulmonary edema, HF
- A leading cause of transfusion death
- ARDS
- A leading cause of transfusion death

Clinical Pearl
Flank pain + dark urine = hemolytic. TACO has high BP and high BNP; TRALI has low BP and normal BNP.
