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.

Comparison
- ABO incompatibility then RBC destruction
- Recipient antibodies vs donor WBCs
- Most common reaction
- Hypersensitivity to donor plasma proteins
- Volume overload — too much, too fast
- Donor anti-leukocyte Ab then non-cardiac edema
- ★Flank/back pain, dark urine (ABO mismatch)
- Onset <15 mL
- fever, chills
- Fever ≥ 1°C rise + chills
- During or within 1–4 hr
- no rash
- Urticaria, hives, pruritus, flushing
- Anaphylaxis then wheeze, hypotension
- Dyspnea, crackles, JVD, hypertension
- Within 1–2 hr
- peripheral edema
- Acute dyspnea, hypoxemia within 6 hr
- + Coombs, ↓ haptoglobin, hemoglobinuria
- Diagnosis of exclusion
- cultures negative
- Clinical
- vitals normal except skin
- ★↑ BNP, ↑ PCWP
- CXR edema + cardiomegaly
- ★Normal BNP/PCWP
- CXR bilateral infiltrates
- Stop the transfusion immediately
- Send bag + sample to blood bank
- NS, UOP ≥30
- Stop the transfusion immediately
- Rule out hemolytic first
- keep NS open
- Stop the transfusion immediately
- Assess airway
- Stop the transfusion immediately
- Sit upright
- O₂
- strict I&O
- Stop the transfusion immediately
- Respiratory support
- Supportive
- treat DIC if it develops
- Antipyretic (acetaminophen)
- Diphenhydramine
- epinephrine if anaphylaxis
- ★Furosemide IV
- ★NO diuretics
- O₂, possible intubation
- 2-RN ID check prevents ABO error
- Leukoreduced units
- premedicate next time
- Premedicate antihistamine
- wash RBCs if recurrent
- Transfuse slowly
- diuretic between units
- Report for donor workup/deferral
- Progresses to shock + DIC
- Must exclude hemolytic before resuming
- ★Anaphylaxis then airway compromise, shock
- Respiratory failure from overload
- Severe hypoxemia then ARDS
- Acute kidney injury, DIC, death
- Benign, self-limited
- Anaphylactic shock
- Pulmonary edema, cardiac failure
- ARDS
- leading cause of transfusion death
Acute Hemolytic

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