Definition & Operational Usage of Keloid

What Is Keloid?

A keloid is a benign, hyperplastic overgrowth of dense fibrous scar tissue that extends beyond the original boundaries of a skin wound, caused by excessive collagen deposition during healing following thermal burns, surgical incisions, or traumatic lacerations.

⚠️ Operational Safety Warning:Avoid placing IV lines, IO needles, or ECG adhesive electrodes directly over dense keloid tissue, as skin puncture is difficult and absorption/adhesion is poor.

Why Keloid Matters on the Fireground

Firefighters and burn victims with extensive keloid formation over joint areas (elbows, shoulders, hands) experience severe contractures and restricted mobility. Identifying keloid tissue during EMS patient exams avoids placing IVs or monitors over fragile scar tissue.

Relevant NFPA Standards

  • NREMT Standards: National Registry of Emergency Medical Technicians Practice Standards
  • NFPA 455: Standard for Emergency Medical Services (EMS)

Field Procedures & Tactical Steps

  1. Note location and extent of keloid scar tissue during secondary physical exam.
  2. Select alternative venipuncture sites clear of heavy scar tissue to ensure proper IV catheter insertion.
  3. Assess joint range of motion if keloid contractures cross major flexor or extensor surfaces.
  4. Protect keloid tissue from friction, shearing, or secondary thermal burns during patient packaging.
  5. Document pre-existing scar formations clearly on the Patient Care Report.

Common Context & Application

Observed during physical examinations of burn survivors, trauma patients, and individuals with prior surgical history.

Frequently Asked Questions about Keloid

How does a keloid differ from a hypertrophic scar?
A hypertrophic scar remains within the original wound boundaries and often regression over time, whereas a keloid expands beyond the original wound margins and rarely regresses spontaneously.
Why are burn patients at high risk for keloid contractures?
Deep partial and full-thickness thermal burns trigger prolonged inflammatory responses and massive collagen synthesis, leading to thick keloid bands that pull joints into fixed flexed positions.
