What is the treatment for fingertip crepitus after acid exposure?

Treatment for Fingertip Crepitus After Acid Exposure

For fingertip crepitus after acid exposure, immediate copious irrigation with water is the first-line treatment, followed by wound assessment and appropriate wound care based on the extent of injury. 1

Initial Management

• Immediately irrigate the affected area with copious amounts of water to remove any remaining acid (Class I, LOE B) 1
• Remove any contaminated clothing or items that may contain acid residue 1
• Do not attempt to neutralize the acid with other chemicals as this may cause additional thermal injury 1
• Assess the extent of tissue damage after thorough irrigation 1

Assessment of Fingertip Crepitus

• Crepitus (subcutaneous air) after acid exposure may indicate:
  • Tissue necrosis with gas-forming organisms 1
  • Non-infectious subcutaneous emphysema from high-pressure injection of air if compressed air was used in cleaning 2
• Perform careful examination to determine:
  • Depth of injury (superficial vs. deep) 3
  • Presence of exposed bone, tendon, or nail bed 3
  • Extent of soft tissue loss 4

Treatment Approach

For Superficial Injuries with Crepitus

• Clean the wound thoroughly with antiseptic solution after irrigation 3
• Consider conservative management allowing wounds to heal by secondary intention if:
  • Minimal tissue loss is present 3
  • No exposed bone or tendon 4
• Apply appropriate dressing:
  • Silver sulfadiazine has been shown to result in shorter healing time compared to other dressings (based on comparative studies) 5
  • Cover with non-sterile PVC glove and redress every third day 5

For Deeper Injuries with Crepitus

• Surgical consultation may be necessary for:
  • Exposed bone or tendon 4
  • Significant tissue loss 4
  • Signs of infection 1
• Treatment options include:
  • Local flap reconstruction for covering exposed structures 4
  • Regional flap reconstruction for larger defects 4
  • Revision or completion amputation if tissue is non-viable 4
  • Nail bed repair if the nail matrix is involved 4

For Suspected Infection with Crepitus

• If infection is suspected (increasing pain, erythema, purulent drainage):
  • Consider antibiotic therapy with amoxicillin-clavulanate as first-line treatment 6
  • Duration of prophylaxis in high-risk wounds is typically 3-5 days 6
  • Surgical debridement may be necessary for necrotizing infections 1

Follow-up Care

• Monitor for signs of infection including increasing pain, erythema, or drainage 1
• Ensure proper wound care with regular dressing changes 5
• Consider occupational therapy for severe injuries to maximize functional recovery 4
• Be aware that common complications include nail deformity, cold intolerance, and painful neuroma formation 4

Special Considerations

• Hand hygiene is critical when treating these injuries to prevent secondary infection 1
• Use lukewarm water (not hot) for hand washing to avoid additional skin damage 1
• Apply moisturizer after wound care to maintain skin barrier function in unaffected areas 1
• Avoid petroleum-based products if latex gloves will be used during treatment 1
• For children, treatment should be more conservative with emphasis on preservation of digital length 3, 7
