Overall Verdict: Mostly Correct - with a few small issues

IMAGE 1

• Dry sterile dressing for primary intention wounds - correct.
• Removed once drainage stops or in 2-3 days - correct.
• Medicated sprays / transparent film also used - correct.

• Wet-to-dry dressing, wound irrigation, whirlpool = 3 methods - correct. These are the classic 3 mechanical debridement techniques (as confirmed by Textbook of Family Medicine 9e and Bailey & Love's).

• Topical agents (Collagenase, Papain, Urea) dissolve necrotic tissue - correct. These are the standard enzymatic agents (confirmed by multiple textbooks including Dermatology 5e and Textbook of Family Medicine 9e).

• Body's own enzymes and moisture break down dead tissue - correct. This is the standard definition.

• Suction removes drainage, reduces bacterial load, promotes blood flow - ✅ correct.
• "Gauze is cut to the dimensions of the wound" - ⚠️ Minor inaccuracy: Traditionally, NPWT uses foam (polyurethane or polyvinyl alcohol), not gauze. Gauze-based NPWT (e.g., VAC Whitefoam) does exist but foam is the primary/standard material. Describing it as "gauze" may reflect a specific system but is not universally accurate.
• A small hole is made where tubing is attached, connected to a pump - ✅ correct.
• Creates negative pressure in wound bed, pulls excess fluid - ✅ correct.

IMAGE 2

• 100% O₂ at 1.5-3 times atmospheric pressure - ⚠️ Partially incorrect. The standard range is 2.0 to 2.4 ATA (or broadly 2-3 ATA). Starting at 1.5 ATA is lower than the standard therapeutic range for wound healing. The widely cited range is 2.0-3.0 ATA, not 1.5-3 ATA.
• Stimulates angiogenesis - ✅ correct.
• Kills anaerobic bacteria - ✅ correct.
• Boosts WBC / antibiotic action - ✅ correct (HBO enhances leukocyte oxidative killing and potentiates certain antibiotics).

• Platelet-derived growth factor released from platelets, stimulates cell proliferation and migration - ✅ correct.
• Becaplermin = a recombinant human platelet-derived growth factor - ✅ correct (confirmed by textbook sources).

• High fluid intake needed to replace fluid loss from exudate formation - ✅ correct.
• Diet high in protein, carbohydrate, and vitamins with moderate fat - ✅ correct. Protein is especially important for collagen synthesis and healing.

• Local warm bath or moist heat pad applied under sterile or aseptic conditions - ✅ correct.

Summary of Corrections

Surgical Management of Wounds

1. Pre-operative Preparation

• Antibiotic prophylaxis - given for contaminated, bite, or heavily soiled wounds
• Tetanus prophylaxis - assessed based on immunization history and wound type (tetanus-prone vs. high-risk tetanus-prone)
• Adequate analgesia / anaesthesia - local, regional, or general depending on the wound
• Wound irrigation - copious saline/water irrigation to reduce bacterial load before formal repair

Tetanus-prone wounds include puncture injuries, bites, compound fractures, wounds containing foreign bodies, and wounds with systemic sepsis. High-risk tetanus-prone wounds include those with heavy contamination (soil/manure), wounds requiring surgery with >6 hour delay, and extensive devitalized tissue. (Bailey & Love's, 28th Ed)

2. Surgical Debridement

• Excision down to healthy tissue - non-viable tissue must be excised until healthy bleeding occurs at wound edges
• Repeated debridement may be needed in heavily contaminated or necrotizing wounds
• Types of surgical debridement:

3. Wound Exploration

• Inspect the full depth and course of the wound
• Remove foreign bodies (glass, debris, metal) - significantly increases infection risk if left in
• Assess injury to underlying structures: neurovascular bundles, tendons, bones, joints
• Probing with a blunt metal instrument; avoid blind finger probing
• Radiopaque foreign bodies visible on X-ray; wood/rubber may require USS, CT, or MRI
• Haemostasis - achieved before closure

4. Wound Closure - Types

A. Primary Closure (First Intention)

• Wound edges are immediately approximated after debridement
• Best for: clean wounds, surgical incisions, wounds less than 6-8 hours old
• Advantages: fastest healing, minimal scarring, less discomfort
• Closure must be without tension

B. Secondary Closure (Second Intention)

• Wound is left open and allowed to heal by granulation, contraction, and epithelialization
• Best for: highly contaminated/infected wounds, abscesses, wounds with significant tissue loss
• Slower process, dependent on myofibroblasts and fibroblasts
• Results in a larger scar
• Dressing changes required throughout

C. Delayed Primary Closure / Tertiary Closure (Third Intention)

• Wound is initially cleansed, irrigated, and packed with moist sterile gauze
• Dressing left undisturbed for 4-5 days (unless signs of infection appear: fever, pus, spreading cellulitis)
• After 4-5 days, if no infection, wound edges are surgically closed
• Best for: highly contaminated wounds, animal bites, war wounds, wounds with initial oedema

5. Methods of Wound Closure

6. Reconstructive Ladder (When Direct Closure Fails)

1. Primary closure - direct approximation
2. Secondary closure - heal by granulation
3. Delayed primary closure
4. NPWT (Negative Pressure Wound Therapy) - useful adjunct, not a replacement for definitive closure
5. Split-thickness skin graft (STSG) - epidermis + small portion of dermis; requires well-vascularized recipient bed
6. Full-thickness skin graft (FTSG) - epidermis + majority of dermis; better cosmesis
7. Local/regional flap - tissue transferred with intact blood supply from nearby donor site
8. Pedicled flap - tissue remains attached to original blood supply during transfer
9. Free flap - tissue with vascular pedicle detached entirely, microvascular anastomosis performed at recipient site (most complex)

Key distinction: A skin graft has no inherent blood supply and depends entirely on the recipient site for survival. A flap carries its own intrinsic blood supply and does not depend on the recipient bed.

7. Adjuncts to Surgical Management

• NPWT / VAC therapy - suction removes exudate, reduces bacterial load, promotes granulation tissue; foam cut to wound dimensions, tubing connected to pump
• Drains - considered when dead space or fluid accumulation is expected
• Antibiotic therapy - systemic for contaminated wounds, necrotizing fasciitis, spreading cellulitis
• Hyperbaric oxygen - adjunct in non-healing/ischemic wounds (2-3 ATA)

8. Wound Closure Considerations

• Closure without tension is mandatory - excessive tension leads to ischaemia and dehiscence
• Suture choice depends on tissue layer, location, and whether removal is feasible
• Drains placed when dead space cannot be eliminated
• Dressings selected based on wound type (dry sterile for primary intention, moist for open wounds)

9. Follow-up

• Suture/staple removal at appropriate intervals (face: 3-5 days; scalp: 7-10 days; trunk/extremities: 10-14 days)
• Physiotherapy for wounds over joints
• Monitoring for complications: infection, dehiscence, haematoma, seroma, hypertrophic scarring, keloid
• Scar management: pressure garments, silicone sheets, steroid injections for hypertrophic scars

• Tissue adhesive - for small, superficial, low-tension wounds
• Adhesive tapes (Steri-strips) - least tissue reactive, for very superficial wounds

• Achieve haemostasis before closing
• Obliterate dead space to prevent haematoma/seroma
• Close in layers (deep tissue, then skin)
• Insert a drain if fluid accumulation is expected
• Choose appropriate suture material (absorbable for deep layers, non-absorbable or absorbable for skin)

• Face: 3-5 days
• Scalp: 7-10 days
• Trunk/limbs: 10-14 days

• Surrounding skin - check for maceration, cellulitis, or discoloration

2. Aseptic Technique During Dressing Change

• Wash hands thoroughly before and after
• Use sterile gloves, sterile instruments
• Clean wound from inside out (clean to dirty) to prevent introducing organisms into the wound
• Dispose of soiled dressings immediately

3. Wound Cleaning

4. Appropriate Dressing Selection

5. Pain Management

6. Immobilization

7. Elevation

8. Nutritional Support

• Zinc - promotes cell proliferation
• Fluids - to replace losses from wound exudate

9. Infection Prevention & Monitoring

• Redness, warmth, swelling, increasing pain
• Fever, purulent (pus) discharge
• Red streaks spreading up the limb (lymphangitis - serious)

10. Patient Education
