Wound Care and Infection Treatment: The Complete Guide for Any Situation

Understanding Wound Types

Incised Wound — clean edges from a sharp object. Bleeds significantly but closes well with lower infection risk if cleaned promptly.
Contused Wound — blunt impact. Irregular, crushed edges. Higher risk of necrotic tissue and infection.
Abrasive Wound — scrape or graze. Superficial but frequently contaminated with dirt and bacteria. Requires thorough cleaning.
Puncture Wound — small entry but potentially deep. High anaerobe risk (tetanus). Extremely dangerous and frequently underestimated.
Avulsion Wound — tissue partially or fully torn away. Requires specialist care but correct first aid makes an enormous difference.

STEP 1 — Wound Cleaning: The Most Important Thing

Correct cleaning is more important than any dressing or medication. A wound cleaned with simple materials heals better than a "well-dressed" but dirty wound.

1. Wash your hands first — at least 20 seconds with soap and water, or use hand sanitiser.

2. Control bleeding first — apply direct pressure before cleaning.

3. Abundant irrigation with clean water This is the most underestimated and most effective wound-cleaning step:

• Minimum volume: 250 to 500 ml per moderate wound

• Serious or contaminated wounds: 1 litre or more

• Use pressure (syringe, squeezed bottle, tap pressure) — water pressure physically removes bacteria and debris that no antiseptic can eliminate chemically

• Wash from the centre outward, never inward

4. Remove visible foreign bodies with a sterilised tweezers (passed through flame or alcohol). Do not force removal of deeply embedded objects — immobilise and transport.

5. Antiseptic — right and wrong: ✅ Use: Diluted chlorhexidine (0.05%) — the best antiseptic for wounds. Diluted povidone-iodine (0.5–1%) is also effective.
⚠️ Use with caution: Hydrogen peroxide — effective against anaerobes but damages healthy tissue. Use only on initial cleaning, never on healing wounds.
❌ Never apply directly to wound: 70% alcohol, iodine tincture, mercurochrome — they kill the cells trying to heal and delay recovery.

6. Dry gently with gauze or clean cloth using dabbing motions — never rub.

STEP 2 — Correct Dressing

When to cover: exposed to dirt, friction or moisture; wound still wet or with discharge. When to leave open: small, superficial, dry wound or well-formed scab in good-circulation area.

How to dress correctly:

1. Apply antibiotic ointment (neomycin, bacitracin) if available

2. Cover with non-stick gauze or inner side of commercial dressing

3. Wrap with elastic bandage — firm but not circulation-restricting

4. Change dressing: every 24h for clean wounds; every 12h if discharging; immediately if wet or dirty

Edge approximation (improvised closure): With steri-strips or narrow-cut surgical tape:

1. Dry the wound edges thoroughly

2. Gently bring edges together with your fingers

3. Apply strips perpendicular to the cut, 3 to 5 mm apart

Improvised suture (extreme emergencies only):

• Use suture thread or thin monofilament fishing line

• Sterilise needle and thread with flame or alcohol

• Simple interrupted stitches — never overtighten

• Spacing: 0.5 to 1 cm between stitches

Do not suture: wounds older than 6–8 hours, infected wounds, necrotic or dirty wounds.

STEP 3 — Recognising and Treating Infection

Infection is the silent enemy of wounds. It starts locally but can spread to the bloodstream (sepsis) within days — and sepsis kills within hours.

Signs of infection — in order of increasing severity:

🟡 Early signs (act now to prevent progression):

• Increasing redness around the wound

• Swelling and warmth beyond what's expected

• Pain that increases rather than decreases after 48 hours

• Yellow or greenish discharge (pus)

• Unpleasant smell from the wound

🟠 Intermediate signs (urgent treatment needed):

• Red streaks spreading from the wound (lymphangitis — infection spreading through the lymphatic system)

• Swollen lymph nodes near the wound (armpit, groin, neck)

• Fever above 38°C

• General malaise, weakness and chills

🔴 Severe signs — MEDICAL EMERGENCY:

• Fever above 39.5°C

• Mental confusion

• Heart rate above 100 bpm

• Skin darkening around the wound (necrosis)

• Crackling sensation on touch (gas gangrene)

Sepsis kills in 6 to 72 hours if untreated. Any serious sign requires immediate emergency transport.

How to treat local infection:

1. Intensify cleaning to 3 times per day

2. Drain pus — gently press wound edges to release content, then irrigate thoroughly

3. Warm compresses 15–20 minutes, 3 times per day — improve local circulation and immunity

4. Antibiotics if available — amoxicillin or cephalexin are first-line for skin infections

5. Immobilise the affected limb and keep elevated

6. Monitor constantly — if signs worsen in 24–48h, seek urgent medical care

PART 4 — Natural Alternatives When Medications Are Unavailable

🍯 Raw Honey (The Best Natural Resource)

Multiple mechanisms: acid pH (3.2–4.5) inhibits bacterial growth; osmotic activity dehydrates bacteria; slow-release hydrogen peroxide has antibacterial effect; anti-inflammatory properties reduce swelling. Apply a generous layer of raw, pure honey directly to a clean wound. Cover with dressing. Change every 12–24h. Never use industrially processed honey.

🌿 Plantain (Plantago major)

Fresh leaves, crushed or chewed, applied to wounds have documented anti-inflammatory, antimicrobial and wound-healing properties. Change every 6–8h.

🧅 Garlic (Allium sativum)

Allicin has potent antibacterial activity — including against antibiotic-resistant bacteria. Apply fresh garlic juice lightly to superficial wounds only. Dilute if it causes intense burning. Do not use on deep open wounds.

🌵 Aloe Vera

Internal gel has anti-inflammatory, moisturising and soothing properties. Excellent for burns, abrasions and surface wounds in the healing phase. Change every 8–12h.

🌊 Salt Water (Improvised Normal Saline)

One level teaspoon of salt in 500 ml of boiled and cooled water. Use for abundant irrigation — do not leave salt in prolonged contact with the wound.

🎥 Watch: Natural wound treatments in survival:

Wounds Requiring Immediate Medical Attention

Do not attempt to treat alone if:

• The wound is over 2 cm long with separated edges (needs suturing)

• Bone, tendon or yellow fat is exposed

• Caused by an animal bite (high rabies and infection risk)

• Deep embedded foreign body that cannot be removed

• Caused by a rusty or heavily contaminated object (tetanus risk)

• Any sign of serious infection is present

• The victim's tetanus vaccination is not up to date (last 5–10 years)

Minimum Wound Care Kit

• Nitrile disposable gloves

• Normal saline or sterile water (for irrigation)

• Diluted chlorhexidine antiseptic

• Sterile gauze and non-stick (vaseline) gauze

• Elastic bandages and medical tape

• Steri-strips or butterfly closures

• Antibiotic ointment (neomycin/bacitracin)

• Sterilisable tweezers and scissors

• 20 ml syringes (for pressurised irrigation)

• Thermometer (to monitor fever)

Golden Rules for Wound Care

• Cleaning matters more than any medication

• Never apply alcohol directly to a wound — it kills healing cells

• Change dressings regularly — a wet, dirty wound is a bacterial breeding ground

• Always monitor — improving or worsening? If worse in 48h, seek help

• Stay hydrated — healing consumes water and nutrients

• Never pop burn blisters — they are natural protective barriers
