OPD Wound Dressing for a 75-Year-Old Diabetic Patient

Clinical Assessment Before Dressing

• Location and size of the wound (foot/leg ulcer most common in diabetics)
• Wagner Grade classification (Grade 0-5) for diabetic foot ulcers
• Wound bed: clean granulating tissue vs. slough vs. necrosis
• Exudate: none / mild / moderate / heavy
• Signs of infection: erythema, warmth, purulent discharge, odor, probe-to-bone test
• Vascular status: peripheral pulses, ABI if available
• Blood sugar: check on arrival - poorly controlled sugar impairs healing
• Neuropathy assessment: monofilament test

Pharmacy Prescription

---

---

Rx - Dressing Consumables (To Purchase from Pharmacy)

---

Rx - Topical Agents (Based on Wound Condition)

---

Rx - Systemic Medications (Essential in Diabetic Wound)

Note on pain control in elderly (75 years): Avoid NSAIDs (renal risk, GI bleed). Use Paracetamol 500 mg orally before dressing if pain is anticipated.

---

• CBC, CRP / ESR
• Wound swab C/S (if infected)
• X-ray foot (2 views - rule out osteomyelitis)
• Peripheral Doppler / ABI (if ischemic component suspected)

---

Detailed Dressing Procedure (OPD Setting)

Step 0 - Preparation (Before the Patient Arrives at Dressing Table)

1. Wash hands thoroughly with soap and water for 20 seconds.
2. Lay out sterile dressing tray:
   • 2 pairs of sterile forceps
   • Sterile gauze pieces (minimum 10-15)
   • Kidney tray for waste
   • Cotton wool
   • Small bowls for saline and antiseptic
3. Pour normal saline into one bowl, diluted povidone-iodine (1:10) into another.
4. Keep silver sulfadiazine cream / impregnated gauze ready.
5. Ensure good lighting and patient comfort (seated or supine as appropriate).

---

Step 1 - Patient Positioning and Communication

• Seat or lay the patient comfortably. For foot wounds, elevate the limb slightly.
• Explain the procedure to the patient calmly (elderly patients may be anxious).
• Administer Paracetamol 500 mg orally 30 minutes before dressing if pain is expected.
• Check blood glucose on glucometer. If >250 mg/dL, note and inform the doctor before proceeding.

---

Step 2 - Removing the Old Dressing

1. Don clean (non-sterile) gloves first.
2. Gently loosen the adhesive tape or bandage. If the outer bandage is soiled, cut with sterile scissors.
3. If the inner gauze is stuck to the wound (dried exudate), soak with normal saline for 2-5 minutes - do NOT pull forcefully (pulling tears the healing tissue).
4. Remove the old dressing carefully using forceps, moving from the outer edges inward.
5. Discard old dressing in a biomedical waste bag (yellow bag for infectious waste).
6. Remove and discard the first pair of gloves.
7. Perform hand hygiene again (alcohol-based hand rub or soap and water).

---

Step 3 - Wound Inspection

• Size of wound (measure if possible - length x width x depth in cm)
• Color of wound bed:
  • Red/Pink: healthy granulation - good sign
  • Yellow: slough present - needs debridement
  • Black/Brown: necrosis - needs surgical referral
• Amount and color of exudate: serous / serosanguineous / purulent
• Periwound skin: maceration, callus, erythema
• Odor: foul smell suggests anaerobic infection
• Probe-to-bone test: if deep ulcer, gently probe with sterile swab; if bone is felt, osteomyelitis must be assumed (refer to surgeon)

---

Step 4 - Wound Cleaning

1. Don sterile gloves now.
2. Using sterile gauze held with forceps, clean the wound with normal saline (0.9% NaCl):
   • Wipe from the center of the wound outward in a circular motion
   • Use a fresh gauze piece for each wipe (never go back)
   • Repeat 3-4 times until wound bed is visibly clean
3. For the periwound skin (intact skin around the wound):
   • Apply diluted povidone-iodine (1:10 in saline) with a swab, moving outward
   • Allow to dry for 30 seconds
4. Do NOT use concentrated povidone-iodine, hydrogen peroxide, or acetic acid directly on the open wound bed - these agents inhibit fibroblast activity and impair healing (per Swanson's Family Medicine and Schwartz's Surgery).
5. If there is visible slough, perform gentle mechanical debridement with a saline-soaked gauze using light friction. Heavy necrotic tissue requires sharp/surgical debridement by the physician.

---

Step 5 - Applying the Primary Dressing (Contact Layer)

1. If using cream (silver sulfadiazine): apply a 2-3 mm thick layer directly to the wound with a sterile spatula or gloved finger.
2. If using impregnated gauze: apply with forceps, lay flat without folding.
3. Ensure the dressing covers the entire wound bed and 1-2 cm of periwound skin.
4. For deep wounds / cavity wounds: loosely fill the cavity with alginate ribbon or gauze soaked in saline - do NOT pack tightly as it restricts blood flow and granulation.

---

Step 6 - Secondary Dressing (Padding and Protection)

1. Cover the primary dressing with dry sterile gauze (2-3 layers) to absorb any exudate.
2. Cover with sterile cotton wool pad for padding and pressure distribution.
3. In diabetic patients, avoid excess pressure on bony prominences (malleoli, metatarsal heads).
4. Secure with crepe bandage applied from distal to proximal (e.g., toes to ankle) with moderate, uniform tension - not too tight (impairs circulation) and not too loose (dressing will shift).
5. Fix outer layer with micropore tape. Do NOT apply tape directly on periwound skin of elderly patients (fragile skin - tape tears).

---

Step 7 - Post-Dressing Care Instructions to Patient

• Keep the dressing clean and dry. Do not wet it.
• Do not remove the dressing at home without advice.
• Return immediately if: fever develops, wound pain increases, dressing becomes wet/soaked, foul smell noticed, red streaking on skin (cellulitis).
• Wear comfortable, well-fitting footwear - no tight shoes, no walking barefoot.
• Blood sugar monitoring at home: FBS daily. Target <130 mg/dL.
• Strict diabetic diet. No alcohol.
• Limb elevation when resting (reduces edema and promotes healing).
• Take all prescribed tablets regularly.
• Next dressing appointment: _____________ (usually every 1-2 days initially)

---

Step 8 - Waste Disposal and Documentation

1. Discard soiled dressings and used gloves in yellow biomedical waste bin.
2. Sharps (needles if any) in red/white puncture-proof container.
3. Document in OPD notes:
   • Wound description (size, depth, tissue type, exudate, signs of infection)
   • Dressing material used
   • Blood glucose reading
   • Patient instructions given
   • Next review date

What is Nano Silver / Colloidal Silver at 32 PPM?

---

Mechanism of Action (How Megaheal Works)

---

Why Megaheal (32 PPM Nano Silver) is Ideal for a 75-Year-Old Diabetic

• Diabetic wounds are highly susceptible to polymicrobial infection - broad spectrum coverage of nano silver is ideal
• Elderly patients have impaired immunity - external antimicrobial dressing reduces systemic antibiotic burden
• Does not damage fibroblasts unlike iodine or H2O2 when used at correct concentration
• No resistance development - silver has a physical/ionic mechanism, bacteria cannot develop resistance like they do to antibiotics
• Works well in moist environments - diabetic wounds tend to be exudative

Dressing Procedure Using Megaheal

Step-by-step:

• Irrigate gently with normal saline only (no H2O2, no povidone-iodine inside wound)
• Pat dry with sterile gauze using light dabbing motion

• Squeeze a thin, uniform layer (2-3 mm) of Megaheal gel directly onto the wound bed
• Ensure the entire wound surface is covered
• Extend slightly (5 mm) onto periwound skin edges
• Do NOT rub - just lay it on gently

• Place 1-2 layers of sterile gauze over the Megaheal
• The gel keeps the gauze from sticking

• Place absorbent cotton pad on top for exudate absorption

• Wrap distal to proximal
• 2 anchoring turns at base
• Figure-of-8 around ankle if foot wound
• Moderate tension only - should be able to insert one finger under bandage
• Fix with micropore tape

Important Notes on Megaheal Use

• Do NOT mix with iodine-based products - silver + iodine precipitates and inactivates both
• Do NOT use on patients with known silver allergy
• Store away from direct sunlight (nano silver degrades with UV exposure)
• For deep cavity wounds - pack loosely with silver-impregnated ribbon gauze (like Aquacel Ag) first, then cover with Megaheal on top
• If no improvement in 2 weeks despite Megaheal - send wound swab for C/S and escalate to systemic antibiotics; consider vascular assessment
