Pathway Overview
15 steps
Algorithm Steps
15 total
01Start 02Warning LIFE-THREATENING EMERGENCY
Mortality 40-50%, requires immediate intervention
- Microvascular thrombosis → tissue necrosis
- Associated with DIC
- Progression from erythema → purpura → necrosis
- Multi-organ failure common
- ICU admission mandatory
03Action Clinical Presentation
Characteristic progression
- Initial: Erythematous macules
- Evolution: Blue-black hemorrhagic purpura
- Progression: Vesicles, bullae, hard eschars
- Pain initially, then sensory loss
- Fever, hypotension, hemorrhage elsewhere
- End-organ damage (renal, pulmonary)
04Decision Classify Type of Purpura Fulminans
Three distinct forms with different triggers
05Action Neonatal Form
Hereditary protein C/S deficiency
- Onset: Within 5 days of birth
- Incidence: 1 per million live births
- Cause: Severe protein C, S, or antithrombin III deficiency
- Systemic thrombosis
- Screen family members
06Action Immediate Resuscitation
ABC stabilization and sepsis management
- IV access, aggressive fluid resuscitation
- Vasopressors if needed
- Broad-spectrum antibiotics STAT
- Blood cultures before antibiotics if possible
- Airway management as needed
07Action Antibiotic Therapy (Infectious Form)
Empiric coverage for likely pathogens
- Carbapenem (meropenem) + Vancomycin
- OR Ceftriaxone + Vancomycin
- ADD Clindamycin for toxin inhibition
- Adjust based on cultures
- Duration: Complete course for source
08Action Laboratory Monitoring
Serial coagulation and organ function
- PT/PTT, fibrinogen, D-dimer (DIC panel)
- Platelet count
- Protein C, Protein S, Antithrombin III levels
- Lactate, organ function panels
- Blood cultures, wound cultures
- CBC with differential
09Action Additional Therapies
Consider based on severity and response
- IVIG 1g/kg/day x 2 days (immunomodulation)
- Activated Protein C (drotrecogin alfa) - if available
- Corticosteroids for adrenal insufficiency
- Plasmapheresis (post-infectious form)
- Hyperbaric oxygen (limited evidence)
10Warning Surgical Management
Often required for survival
- Early surgical consultation
- Fasciotomy for compartment syndrome
- Debridement of necrotic tissue
- May require amputation of extremities
- Skin grafting in recovery phase
- Timing based on patient stability
11Outcome Survival
Significant morbidity expected
- Major amputations common
- Skin grafting required
- Long-term rehabilitation
- Genetic counseling (hereditary forms)
- Lifelong anticoagulation may be needed
12Warning Death
Mortality 40-50%
- Multi-organ failure
- Refractory septic shock
- Hemorrhage
- Early palliative care discussion appropriate
13Action DIC and Coagulation Management
Restore coagulation balance
- Fresh frozen plasma (FFP) for clotting factors
- Platelet transfusion if <50,000 or bleeding
- Cryoprecipitate if fibrinogen <100 mg/dL
- Protein C concentrate if available (neonatal form)
- Antithrombin III replacement if deficient
- Heparin controversial - consider if thrombosis dominant
- Path rejoins step 08Shared downstream outcome
14Action Idiopathic (Post-Infectious)
Acquired protein S deficiency
- Onset: 7-10 days after infection
- Preceding: Varicella, scarlet fever most common
- Mechanism: Anti-protein S antibodies develop
- Transient deficiency
- Rarest form
- Path rejoins step 06Shared downstream outcome
15Warning Acute Infectious Form
Most common - occurs during acute sepsis
- 10-20% of meningococcal septicemia
- Pathogens: N. meningitidis, S. pneumoniae, GAS
- Endotoxin → DIC → protein C consumption
- Higher risk in asplenia
- Most severe form
- Path rejoins step 06Shared downstream outcome
