Wound Management
Ronald Merrell, MD FACSVirginia Commonwealth University
Types of wounds
• Abrasion• Thermal• Puncture or stab• Gunshot high velocity or low velocity• Gunshot high velocity or low velocity• Laceration• Avulsion• Amputation• Open Fracture
Types of Incisions
• Clean• Clean contaminated• Contaminated
Types of Healing
• First Intention. Primary closure• Second Intention. Secondary closure• Third Intention. Granulation and
t ti ft lcontraction or graft closure• Chronic Wound. Biologically very different• Regeneration. Not by scarring
Biology of wound healing
• Day 1-3 inflammation• Day 3-28 proliferation• 1-3 months remodeling

Principles of wound management
• Primum non nocere• “I’m not dead yet”• Get it clean• Do not entomb contamination• Do not entomb contamination• Drain pus. The pressure problem• Allow body to normalize the environment• Remember normal tissue perfusion
pressure (25mmHg)

Venous Stasis ulcer
Adjuncts to healing
• Magic potions, factors, chemicals, creams, antibiotics
• Hyperbaric oxygenP iti• Positive pressure
• Negative pressure• Strong positive thoughts and meditation
This will not hurt much and other lies
• Hypotonic solutions hurt. So do hypertonic • Salt in wound hurts, Saline does not• Ischemia• Stretch• Pressure• Low pH• Excessive heat
What is basic to healing
• Advantage to host rather than microbe• Clean• No Hematoma• Gentle apposition• Gentle apposition• Proper position• Perfusion• Oxygenation• Clean dressing

Final Thoughts• Anticipate the outcome• Does it really look the way you want?• A neat bandage implies careful work• A comfortable bandage is kind. Tape hurtsg p• When you look at a wound the patient is
studying your reaction• When you take down a dressing, ditto• Removing sutures is a big deal• I made the incision, the patient made the scar
