Pathway Overview
15 steps
Algorithm Steps
15 total
01Start 02Action High-Risk Scenarios
Identify patients at risk
- Long bone fractures (femur, tibia)
- Multiple fractures
- Pelvic fractures
- Intramedullary nailing
- Orthopedic procedures
- Liposuction (rare)
- Young adults most commonly affected
03Action Classic Clinical Triad
Onset typically 24-72 hours post-injury
- 1. Respiratory: Hypoxemia, tachypnea, dyspnea (95%)
- 2. Neurological: Confusion, agitation, drowsiness, coma (60%)
- 3. Petechiae: Upper body, axillae, conjunctivae (50%)
- May have fever, tachycardia
- Symptoms develop insidiously
04Decision Apply Gurd's Diagnostic Criteria
Major and minor criteria
- MAJOR CRITERIA:
- - Petechial rash
- - Respiratory symptoms + bilateral infiltrates
- - CNS signs unrelated to head injury
- MINOR CRITERIA:
- - Tachycardia >110
- - Fever >38.5°C
- - Retinal fat emboli on fundoscopy
- - Fat in urine/sputum
- - Drop in Hct or platelets
- - Elevated ESR
- Diagnosis: 1 major + 4 minor, OR 2 major
05Action Investigations
No specific diagnostic test
- ABG: Hypoxemia (PaO2 <60 mmHg)
- CXR: Bilateral diffuse infiltrates ('snowstorm')
- CT chest: Ground glass opacities
- CBC: Thrombocytopenia, anemia
- Lipase: May be elevated
- Fundoscopy: Retinal fat emboli (pathognomonic but rare)
- Urine/sputum: Fat globules (non-specific)
- MRI brain: T2 hyperintensities if neurological
06Decision Severity Assessment
Determine level of care needed
07Action Mild-Moderate FES
Supportive care, close monitoring
- Supplemental oxygen to maintain SpO2 >92%
- Monitor closely for deterioration
- Fluid management (avoid overload)
- Analgesia for comfort
08Action Supportive Treatment
No specific therapy proven
- Maintain adequate oxygenation
- Maintain intravascular volume (careful balance)
- DVT prophylaxis
- Early mobilization when stable
- Albumin infusion (theoretical benefit, unproven)
- Steroids: Not routinely recommended
09Warning ⚠️ Prognosis
Usually self-limiting but can be fatal
- Most patients recover with supportive care
- Mortality 5-15% in severe cases
- Neurological symptoms usually reversible
- ARDS may require prolonged ventilation
- Prevention is key: early fracture fixation
10Action Ongoing Monitoring
Assess for improvement or complications
- Serial ABGs/SpO2 monitoring
- Repeat CXR if deteriorating
- Neuro checks if CNS involvement
- Watch for ARDS development
- Typically resolves in 2-7 days
11Outcome Recovery
Usually complete recovery expected
12Outcome Complications
ARDS, prolonged ICU stay, rare mortality
13Action Severe FES / Fulminant
ICU admission required
- ICU monitoring
- Mechanical ventilation if respiratory failure
- Lung-protective ventilation (low tidal volume)
- PEEP for alveolar recruitment
- May progress to ARDS
- Inotropic support if needed
- Path rejoins step 08Shared downstream outcome
14Action Early Fracture Fixation
Prevention and treatment
- Early fixation (<24h) may reduce FES risk
- Damage control orthopedics if polytrauma
- Avoid reaming in high-risk patients
- External fixation as temporizing measure
- Definitive fixation when stable
- Path rejoins step 10Shared downstream outcome
15Action Differential Diagnosis
Rule out other causes
- Pulmonary embolism (VTE)
- ARDS from trauma/sepsis
- Hospital-acquired pneumonia
- Head injury (for neurological symptoms)
- Drug/medication effects
- Cardiogenic pulmonary edema
- Path rejoins step 06Shared downstream outcome
