Pathway Overview
12 steps
Algorithm Steps
12 total
01Start 02Warning STOP TRANSFUSION IMMEDIATELY
Do not discard blood product - needed for investigation
- Clamp tubing, keep IV access
- Maintain IV with normal saline
- Do NOT discard blood bag
- Notify blood bank immediately
- Notify attending physician
03Action Assess Symptoms
Identify type of reaction
- AHTR signs: Fever, chills, flank/back pain, hypotension, hemoglobinuria, DIC
- Also check: Dyspnea, chest pain, urticaria, anxiety
- Vital signs: BP, HR, Temp, SpO2, RR
- Urine output and color
04Decision Hemodynamic Instability?
Hypotension, shock, respiratory distress
05Warning Severe Reaction - Emergency
Suspected AHTR or anaphylaxis
- Activate rapid response/code if needed
- Aggressive IV fluid resuscitation
- Vasopressors if refractory hypotension
- Epinephrine 0.3-0.5mg IM if anaphylaxis
- Prepare for possible intubation
06Action Laboratory Workup
Blood bank and hemolysis labs
- Repeat type and screen, crossmatch
- Direct antiglobulin test (DAT/Coombs)
- Plasma free hemoglobin
- Haptoglobin, LDH, bilirubin
- CBC, coagulation studies (DIC screen)
- Urinalysis for hemoglobin
- Return blood bag + tubing to blood bank
07Decision AHTR Confirmed?
Positive DAT, hemolysis evidence, clerical error identified
08Action AHTR Management
Prevent renal failure and DIC
- Aggressive IV fluids to maintain UOP >1 mL/kg/hr
- Consider furosemide if volume overloaded
- Monitor for DIC - treat if present
- Supportive care in ICU setting
- Blood bank investigation for root cause
- Report to hospital transfusion committee
09Action Future Transfusion Planning
Prevent recurrence
- Update transfusion history in medical record
- Special requirements: Washed, irradiated, leukoreduced
- Premedication protocol if indicated
- Consider autologous donation if possible
- Patient education about reaction
10Outcome Reaction Managed
Patient stable, investigation complete
11Action Other Transfusion Reaction
FNHTR, allergic, TACO, TRALI, etc.
- FNHTR: Supportive, premedicate future
- Allergic: Antihistamines, can resume if mild
- TACO: Diuretics, slow future transfusions
- TRALI: Supportive, O2, avoid implicated donors
- Document reaction type
- Path rejoins step 09Shared downstream outcome
12Action Mild/Moderate Reaction
Stable vital signs
- Close monitoring
- Antipyretics for fever (acetaminophen)
- Antihistamines for urticaria (diphenhydramine)
- Do not resume transfusion until cleared
- Path rejoins step 06Shared downstream outcome
