Contrast Extravasation Management (ACR 2024)

Contrast Extravasation Management (ACR 2024): Contrast Extravasation Detected → Immediate Actions → Initial Assessment → Risk Stratification → Low Risk ...

Pathway Overview

12 steps

Algorithm Steps

12 total

  1. 01Start

    Contrast Extravasation Detected

    Contrast injected outside vein

  2. 02Warning

    Immediate Actions

    Stop and assess

    • STOP injection immediately
    • Remove IV catheter (don't flush)
    • Document estimated volume extravasated
    • Notify radiologist
    • Examine and document affected area
  3. 03Action

    Initial Assessment

    Evaluate severity

    • ESTIMATE VOLUME:
    • - Power injector: Calculate from injection data
    • - Hand injection: Estimate from swelling
    • EXAMINE:
    • - Location (hand/wrist highest risk)
    • - Circumferential involvement
    • - Skin color and integrity
    • - Capillary refill
    • - Pain level
    • - Motor/sensory function
  4. 04Decision

    Risk Stratification

    Volume and location determine risk

    • LOW RISK: <30-50 mL, large area
    • MODERATE: 50-100 mL
    • HIGH RISK: >100 mL, hand/wrist
  5. 05Action

    Low Risk (<50 mL)

    Conservative management

    • TREATMENT:
    • - Elevate extremity above heart
    • - Cold compress initially (15-20 min)
    • - Then warm compress after 4-6 hours
    • - Reassurance
    • DISCHARGE INSTRUCTIONS:
    • - Keep elevated
    • - Return if: Increasing pain, numbness, blisters
    • - Most resolve in 24-48 hours
  6. 06Action

    Documentation

    Important for follow-up and QI

    • DOCUMENT:
    • - IV site and gauge
    • - Contrast type and concentration
    • - Injection rate
    • - Estimated volume extravasated
    • - Clinical findings
    • - Treatment provided
    • - Follow-up plan
    • - Incident report per policy
  7. 07Outcome

    Outcomes

    Prognosis

    • Most extravasations: No sequelae
    • Large volume: May have prolonged swelling
    • Compartment syndrome: Rare (~0.04%)
    • Skin necrosis: Rare with modern agents
    • Prevention: Good IV technique, antecubital preferred
  8. 08Action

    Moderate Risk (50-100 mL)

    Close monitoring required

    • TREATMENT:
    • - Elevate extremity
    • - Cold compress initially
    • - Serial examinations (q2-4h)
    • - Document progression
    • - Analgesia PRN
    • ESCALATION CRITERIA:
    • - Progressive swelling
    • - Skin changes (blistering)
    • - Neurovascular compromise
    • - Consider plastic surgery consult
  9. 09Decision

    Signs of Compartment Syndrome?

    Surgical emergency

    • Pain out of proportion
    • Pain with passive stretch
    • Tense swelling
    • Paresthesias
    • Weakness
  10. 10Warning

    Compartment Syndrome

    URGENT SURGICAL CONSULT

    • IMMEDIATE:
    • - Plastic/hand surgery STAT
    • - Elevate but NOT above heart level
    • - Remove constrictive items
    • - Measure compartment pressures
    • TREATMENT:
    • - Fasciotomy if confirmed
    • - Time-critical (6-8 hour window)
    • RARE but serious complication
  11. Path rejoins step 06Shared downstream outcome
  12. 11Action

    Skin Necrosis/Ulceration

    Delayed complication

    • RISK FACTORS:
    • - Large volume
    • - Hand/wrist location
    • - Ionic contrast (older agents)
    • - Poor peripheral circulation
    • MANAGEMENT:
    • - Wound care
    • - Plastic surgery referral
    • - May need debridement/grafting
    • TIMELINE: Days to weeks after injury
  13. Path rejoins step 06Shared downstream outcome
  14. 12Warning

    High Risk (>100 mL)

    Potential for serious injury

    • IMMEDIATE ACTIONS:
    • - Elevate above heart
    • - Baseline neurovascular exam
    • - Mark boundaries with skin marker
    • - Serial exams q1-2h
    • CONSULTS:
    • - Plastic surgery (early)
    • - Consider admission
    • WATCH FOR:
    • - Compartment syndrome
    • - Skin necrosis
    • - Ulceration
  15. Path rejoins step 09Shared downstream outcome

Clinical Safety Information

Clinical Decision Support — Not a Substitute for Clinical Judgment

Individual patient factors may require deviation from these recommendations.

Known Limitations

  • Exact volume often unknown
  • Compartment syndrome rare but serious
  • Patient factors affect severity
  • Most resolve without intervention
