Wound Management

Part of First Aid

In a world without hospitals, every cut, scrape, and puncture is a potential death sentence if it becomes infected. Knowing how to clean, close, and care for wounds is one of the most critical survival skills you can develop.

Why Wound Care Is Non-Negotiable

Before antibiotics, infection was the leading cause of death from injury. A simple cut from a rusty nail, an animal bite, or a deep scrape from a fall could — and regularly did — kill otherwise healthy people within days. In a post-collapse scenario, you’re back to pre-antibiotic reality.

The good news: proper wound management dramatically reduces infection risk even without modern medicine. Clean technique, thorough irrigation, and appropriate wound closure can handle the vast majority of injuries you’ll encounter.

Wound Assessment

Before you treat, you need to evaluate. Not all wounds are equal, and the wrong treatment can make things worse.

Wound Types

Type	Description	Primary Concern
Abrasion	Skin scraped off (road rash, falls)	Debris embedded in tissue
Laceration	Clean cut from sharp object	Depth; tendon/nerve damage
Puncture	Small entry, deep penetration (nails, thorns)	Trapped bacteria deep inside
Avulsion	Skin or tissue torn away	Tissue viability; blood loss
Crush injury	Tissue damaged by compression	Internal damage; swelling
Bite	Animal or human teeth	High infection rate (polymicrobial)

What to Check

1. Bleeding severity — Is this life-threatening? If blood is spurting or soaking through fabric rapidly, stop the bleeding first (see Bleeding Control).
2. Depth — Can you see fat (yellow, globular), muscle (dark red, fibrous), tendon (white, cord-like), or bone? Deep wounds need special care.
3. Location — Wounds over joints, on hands/feet, or near the face carry higher functional and cosmetic stakes.
4. Contamination — Dirt, debris, animal matter, rust, or fecal contamination all increase infection risk dramatically.
5. Mechanism — Bites and crush injuries have much higher infection rates than clean cuts.

Wound Cleaning: The Most Important Step

Irrigation is the single most effective thing you can do to prevent wound infection. Study after study in pre-antibiotic era medicine showed that thorough cleaning mattered more than any medication or technique applied afterward.

Water Quality

Use the cleanest water available. In order of preference:

1. Boiled and cooled water
2. Filtered water (through cloth or improvised filter)
3. Clean running water from a known-safe source
4. Any clean water you have — even imperfect water is better than not irrigating

Adding a small amount of salt (roughly 1 teaspoon / 5 g per quart / liter) creates a mild saline solution that’s gentler on tissue than plain water. This is optional — plain clean water works fine.

Do NOT Use These on Open Wounds

• Alcohol — kills tissue and delays healing
• Full-strength hydrogen peroxide — destroys healthy cells along with bacteria
• Iodine (undiluted) — toxic to tissue at full concentration; diluted povidone-iodine (Betadine) is acceptable if available
• Dirt, mud, or plant poultices directly in the wound — folk remedies that introduce infection

Irrigation Technique

1. Remove visible debris with clean fingers or improvised tweezers (two sticks, thorns, or bent wire).
2. Flush the wound with pressure. Use a water container with a small hole, a squeeze bottle, or a plastic bag with a pinhole. You want a forceful stream, not a gentle pour. Aim for at least 250 ml (1 cup) per inch of wound length.
3. Scrub if necessary. For abrasions with embedded gravel or dirt, you may need to scrub with a clean cloth. This is painful but absolutely necessary — debris left in a wound virtually guarantees infection.
4. Flush again after any scrubbing.

The wound should look clean — pink tissue, no visible debris, no dirt. If you can still see foreign material, keep cleaning.

Wound Closure

Not every wound should be closed. This is a critical decision.

Close the Wound If:

• The cut is clean, with sharp edges that align well
• You cleaned it thoroughly within 6-8 hours of injury
• There’s no sign of infection (redness, warmth, pus, foul smell)
• It’s in a location where closure reduces scarring or improves function (face, hands, over joints)

Leave the Wound OPEN If:

• It’s a bite wound (animal or human) — these have very high infection rates
• It’s a puncture wound — closing traps bacteria inside
• It’s heavily contaminated and you can’t clean it adequately
• It’s older than 8-12 hours (6 hours in hot/humid climates)
• There are signs of infection already present

Open wounds heal from the bottom up (secondary intention). It takes longer and leaves a larger scar, but it’s far safer than trapping an infection inside.

Closure Methods

Adhesive strips (butterfly bandages): Cut thin strips of adhesive tape or medical tape. Apply perpendicular to the wound, pulling edges together without overlapping skin. Space strips 3-5 mm apart. This is the safest method — it allows drainage and can be removed if infection develops.

Improvised sutures: In extreme cases with deep lacerations that won’t stay closed, you can suture with a sterilized needle (heated to red-hot then cooled) and thin thread, fishing line, or dental floss. Pass the needle through skin about 5 mm from the wound edge, across the wound, and out 5 mm on the other side. Tie each stitch individually. Space stitches 5-8 mm apart. This is a last resort — improper suturing causes more problems than it solves.

Hair ties: For scalp wounds, gather hair from each side of the cut, twist together, and tie. Effective and leaves no foreign material in the wound.

Dressing and Bandaging

After cleaning and closure (or deliberate non-closure), protect the wound.

Dressing Layers

1. Contact layer: Clean cloth directly on the wound. Ideally something that won’t stick — lightly oiled fabric or a non-adherent material if available.
2. Absorbent layer: Thicker cloth to absorb drainage. Cotton, wool, or any clean fabric.
3. Securing layer: Bandage wrap, strips of cloth, or tape to hold everything in place. Firm but not tight — you should be able to slide a finger underneath.

Changing Dressings

• Change every 12-24 hours, or sooner if soaked through
• Clean the wound gently with each change
• Watch for signs of infection at every dressing change

Recognizing Infection

Catch it early. Infection progresses fast without antibiotics.

Sign	Timeline	Severity
Increasing pain	24-48 hours	Early warning
Redness spreading from wound edges	24-48 hours	Early warning
Warmth around the wound	24-72 hours	Moderate concern
Swelling beyond wound area	24-72 hours	Moderate concern
Pus (yellow/green/gray drainage)	48-96 hours	Active infection
Red streaks moving away from wound	48-96 hours	Lymphangitis — serious
Fever, chills, feeling unwell	48-96 hours	Systemic infection — life-threatening
Foul smell	Variable	Possible anaerobic or necrotic infection

If Infection Develops

1. Open the wound — remove closures, let it drain
2. Irrigate aggressively with clean water or saline
3. Apply warm compresses (clean cloth soaked in warm water) for 20 minutes, 3-4 times daily — draws infection to the surface
4. Elevate the injured area above the heart if possible
5. Seek any available medical help — systemic infection (fever, red streaks) can kill within days
6. Honey applied directly to the wound has legitimate antimicrobial properties — use raw, unprocessed honey if available. It creates an osmotic environment hostile to bacteria.

Special Cases

Puncture Wounds

Do NOT close. Soak in warm water for 20 minutes to encourage bleeding and flushing from inside out. Watch especially carefully for infection — tetanus-causing bacteria thrive in the deep, oxygen-poor environment of puncture wounds.

Animal Bites

Irrigate immediately and aggressively — at least 5 minutes of running water or pressurized irrigation. Leave open. Bite wounds from carnivores carry rabies risk in addition to bacterial infection. There is no field treatment for rabies once symptoms appear.

Burns

Cool with clean, cool (not cold) water for 10-20 minutes. Do not apply butter, oil, or toothpaste. Cover with clean, non-stick dressing. Do not pop blisters — the skin is a natural sterile barrier. See a separate guide for burn management when available.

Key Takeaways

• Irrigation is the most important step — flush wounds thoroughly with clean water under pressure before anything else
• Never close bite wounds, puncture wounds, contaminated wounds, or wounds older than 8-12 hours
• Change dressings every 12-24 hours and watch for spreading redness, warmth, pus, or red streaks
• If infection develops, open the wound, irrigate, apply warm compresses, and use raw honey if available
• Every wound is a potential fatal infection without antibiotics — treat even minor cuts seriously
