Algorithm Steps

  1. 01Start

    High-Pressure Injection Injury

    Industrial injection through skin

  2. 02Warning

    WARNING: Deceptive Initial Appearance

    Do NOT be fooled by benign presentation

    • Initial wound often appears MINIMAL:
    • - Small puncture wound
    • - Minimal external injury
    • - Patient may minimize symptoms
    • UNDERLYING INJURY IS SEVERE:
    • - Material tracks along tendon sheaths
    • - Spreads through fascial planes
    • - Causes intense inflammation
    • - Leads to compartment syndrome
    • - Vascular compromise
    • THIS IS A SURGICAL EMERGENCY
  3. 03Action

    Critical History

    Determine severity factors

    • WHAT was injected? (critical for prognosis)
    • - Grease/oil: Better prognosis
    • - Paint/solvents: WORSE prognosis
    • - Diesel/hydraulic fluid: Toxic
    • INJECTION PRESSURE:
    • - Industrial guns: 2,000-10,000 PSI
    • - Higher pressure = deeper spread
    • TIME since injury
    • LOCATION:
    • - Index finger most common
    • - Non-dominant hand typical
  4. 04Action

    Physical Examination

    Assess extent of injury

    • INSPECTION:
    • - Entry wound (often small)
    • - Swelling pattern (tracking)
    • - Skin color changes
    • PALPATION:
    • - Crepitus (subcutaneous material)
    • - Compartment tension
    • VASCULAR:
    • - Capillary refill
    • - Pulse exam
    • - Doppler if needed
    • NEUROLOGIC:
    • - Sensory exam
    • - Motor function
  5. 05Action

    Imaging

    Define extent of spread

    • X-RAY:
    • - May show subcutaneous air
    • - May show radiopaque material
    • - Extent of spread
    • MRI (if time permits):
    • - Better soft tissue detail
    • - Usually not needed emergently
    • DO NOT delay surgery for imaging
  6. 06Decision

    Time to Surgery

    Urgent OR within 6 hours

    • <6 hours: Better outcomes
    • >6 hours: Higher amputation rate
  7. 07Action

    Surgical Management

    Wide debridement essential

    • INCISIONS:
    • - Extensile approach
    • - Bruner zigzag or midlateral
    • - Extend to follow material spread
    • DEBRIDEMENT:
    • - Remove ALL visible foreign material
    • - Debride necrotic tissue
    • - Open tendon sheaths widely
    • - Release carpal tunnel if needed
    • - Fasciotomies for compartment syndrome
    • WOUND:
    • - Leave wounds OPEN
    • - Loose packing
    • - VAC if appropriate
    • Plan for second-look at 24-48h
  8. 08Action

    Postoperative Management

    Ongoing care

    • ANTIBIOTICS:
    • - Broad spectrum (Augmentin + Cipro)
    • - Cover skin and gram negatives
    • ELEVATION:
    • - Hand above heart
    • REPEAT DEBRIDEMENT:
    • - Return to OR in 24-48h
    • - Multiple debridements often needed
    • - Continue until clean
    • WOUND CLOSURE:
    • - Delayed primary closure
    • - Skin graft if needed
    • - Flap coverage rare
  9. 09Action

    Complications/Outcomes

    Prognosis

    • COMPLICATIONS:
    • - Amputation: 20-50% overall
    • - Organic solvents: Up to 80% amputation
    • - Stiffness (very common)
    • - Chronic pain
    • - Infection
    • PROGNOSTIC FACTORS:
    • - Delay in treatment: POOR
    • - Organic solvents: POOR
    • - Grease: Better
    • - Distal location: Better
    • - Early surgery: Better
  10. 10Outcome

    Follow-Up

    Long-term care

    • Hand therapy essential
    • Scar management
    • Return to work variable
    • May need reconstructive procedures
    • Workers' compensation often involved

Clinical Safety Information

Clinical Decision Support — Not a Substitute for Clinical Judgment

Individual patient factors may require deviation from these recommendations.

Known Limitations

  • Initial appearance often deceiving
  • Prognosis depends on injected material
  • May require multiple debridements
  • High amputation rate even with treatment
