Wound Care Without Modern Medicine

Wounds are among the most common medical emergencies in any scenario where physical labor, tool use, or conflict is present. Before antibiotics, infected wounds were among the leading causes of death — not the wound itself, but the infection that followed poor care. Understanding what to do in the first hours after injury dramatically changes outcomes.

This guide is organized around priorities: stop bleeding, clean the wound, decide whether and how to close it, watch for infection, and know when to do nothing aggressive and simply allow healing. These principles are drawn from Auerbach's Wilderness Medicine (Auerbach, 2017) and WHO wound care guidelines, and are applicable without modern medical supplies.

Triage and Assessment

Before touching a wound, assess the whole person. In trauma triage, the order of priorities is:

1. Airway: Is the person breathing?
2. Breathing: Is breathing adequate?
3. Circulation: Is there major bleeding? Shock?
4. Disability: Is the person conscious? Is there a spinal injury risk?
5. Exposure: Expose the injury to assess it fully.

Only when immediate life threats are controlled do you turn to wound management. A dramatic-looking laceration on the forearm is not your priority if the person is also going into shock.

Signs of shock (inadequate circulation): rapid weak pulse, pale clammy skin, confusion, rapid breathing, thirst. Lay the patient flat, elevate the legs if no spinal injury is suspected, keep them warm. Shock kills faster than a wound.

Controlling Bleeding

Direct pressure is the first and most effective method for stopping bleeding. Press firmly with the cleanest material available — ideally a clean cloth or bandage — and hold without releasing for a full 10 minutes by the clock. Releasing early to check is the most common mistake; it breaks the clot forming.

Tourniquet: for life-threatening limb bleeding that cannot be controlled by pressure, a tourniquet saves lives. Apply 2–3 inches above the wound (never on a joint), tighten until bleeding stops, note the time of application. A properly applied tourniquet will be painful. This is expected. The historical fear that tourniquets cause amputations is overstated — prolonged tourniquet use beyond 2 hours increases risk, but death from uncontrolled hemorrhage is certain. Modern wilderness medicine guidelines (Auerbach, 2017) support tourniquet use for severe extremity bleeding.

Wound packing: for deep wounds in areas where a tourniquet cannot be applied (groin, armpit, neck), pack the wound cavity firmly with clean cloth and apply sustained pressure.

Wound Cleaning: The Most Important Step

The single most important thing you can do for a wound — more important than closure, more important than antiseptics — is thorough mechanical irrigation.

Studies reviewed in WHO wound care guidelines consistently show that high-pressure irrigation with clean water removes more bacteria and foreign material than any topical antiseptic (WHO, 2016). The goal is to flush debris and bacteria out of the wound physically.

Irrigation technique:

• Use the cleanest water available. Boiled and cooled water is ideal.
• Use a syringe, a plastic bag with a small hole, or even a cupped palm to create pressure. A 20mL syringe with a 19-gauge needle creates optimal irrigation pressure (approximately 8 psi).
• Irrigate copiously. A general rule: 100mL of fluid per centimeter of wound length. For a 5cm laceration, use at least 500mL of water.
• Angle the stream to flush debris outward, not deeper.
• Visually inspect the wound after irrigation. Remove any visible debris with clean tweezers if available.

On antiseptics: hydrogen peroxide, iodine, and alcohol applied directly to wound tissue kill bacteria — but they also damage the healthy tissue cells needed for healing (Lineaweaver et al., 1985). In a clinical setting, these are not recommended for direct wound irrigation. Dilute povidone-iodine (0.9% solution) is acceptable in contaminated wounds in resource-limited settings, but clean water irrigation is preferable and equally effective in most cases.

Remove all foreign material: wood splinters, gravel, fabric fibers. Foreign material left in a wound almost guarantees infection.

Wound Closure: When and How

Not all wounds should be closed. Closure brings the wound edges together, which speeds healing and reduces scarring — but it also traps bacteria inside. If a wound is contaminated, closure creates an ideal anaerobic environment for infection.

When NOT to Close a Wound

• Animal or human bite wounds: These are heavily contaminated with polymicrobial bacteria. Leave open and irrigate repeatedly. (Auerbach, 2017)
• Puncture wounds: Cannot be adequately cleaned at depth. Closing the surface traps contamination below.
• Wounds more than 6–8 hours old (in warm environments) or 12–24 hours old (in cold environments): bacterial colonization is already established.
• Contaminated wounds: soil-contaminated, fecal-contaminated, or visibly dirty wounds that cannot be fully cleaned.
• Wounds showing early signs of infection: redness, warmth, pus, or swelling at the wound edges.

These wounds should be managed open: kept clean, irrigated daily, packed loosely with clean damp cloth if deep, and allowed to heal from the inside out (healing by secondary intention). This is slower but safer.

Closure Methods

Steri-strips and wound closure strips: adhesive strips that draw wound edges together. Appropriate for clean, superficial lacerations under moderate tension. Easy to apply, low infection risk, no skill required. Clean and dry the surrounding skin thoroughly before applying — they will not stick to damp skin.

Wound closure with tape and butterfly strips: improvised from any adhesive tape. Cut strips and apply perpendicular to the wound, spacing them evenly. These are appropriate for the same situations as steri-strips.

Sutures (stitches): appropriate for deeper wounds with significant tension on the edges, wounds in areas that move (joints, scalp), and wounds that have been thoroughly cleaned. Suturing requires practice and appropriate supplies (needle, suture thread, needle holder, scissors). If suturing without training, simple interrupted sutures are the most forgiving: individual stitches placed across the wound, spaced 3–5mm apart, tied off individually so one failure does not compromise the rest. Do not suture contaminated wounds.

Staples: rapid, strong closure for scalp wounds and long lacerations in low-tension areas. Require a stapler. Appropriate in clean wounds. Removal requires a staple remover.

Wound glue (cyanoacrylate): effective for small, clean lacerations under low tension. Do not apply inside the wound — apply only to the skin surface after bringing edges together.

Recognizing and Managing Infection

Wound infection is the most dangerous complication. Learn to recognize it early.

Signs of local infection (confined to the wound):

• Increasing redness and warmth extending from wound edges
• Swelling
• Purulent (pus) discharge — cloudy, yellow, or green
• Increasing pain after the first 24–48 hours (pain that improves then worsens is a red flag)
• Wound edges that fail to adhere or begin to separate

Signs of systemic infection (spreading beyond the wound — a medical emergency):

• Fever above 38.5°C / 101.3°F
• Red streaks extending from the wound toward the body (lymphangitis — infection tracking along lymphatic vessels)
• Swollen lymph nodes
• Rapid heart rate, confusion, or severe malaise

If systemic infection signs appear, the patient needs antibiotics and, if available, hospital care. Without antibiotics, the priority is drainage: open any closed wound that is infected to allow the infection to escape, irrigate daily, and keep it open until fully healed.

Tetanus: any deep wound contaminated with soil, feces, or rust carries tetanus risk. If tetanus vaccination is current (within 5 years for dirty wounds), risk is low. Without vaccination and without antitoxin, tetanus is fatal in 10–20% of cases (CDC). In a rebuilding scenario, maintaining vaccination records for the community is critical.

Natural Antimicrobials

Where pharmaceutical antibiotics are unavailable, several natural materials have documented antimicrobial activity.

Honey: Manuka honey and raw honey have been studied extensively as wound dressings. Honey creates an osmotic environment that draws moisture out of bacteria, lowering its water activity below the threshold for bacterial survival. It also produces low levels of hydrogen peroxide through the enzyme glucose oxidase, and Manuka honey contains an additional antibacterial compound, methylglyoxal (MGO). Clinical trials reviewed by Molan (2001) found honey dressings effective against a broad range of wound pathogens including MRSA. Apply a layer to a clean wound, cover with a dressing. Change daily. Raw local honey works; highly processed honey does not.

Garlic (Allium sativum): Allicin, the active compound released when garlic is crushed, has demonstrated broad-spectrum antibacterial and antifungal activity in vitro (Ankri & Mirelman, 1999). Crush a clove, apply the juice to the wound, cover. It will sting. Repeated application. This is not equivalent to antibiotics but is meaningful in the absence of alternatives.

Calendula (Calendula officinalis, marigold): historically used across Europe and Asia for wound healing. Calendula extracts show anti-inflammatory, antimicrobial, and tissue-regenerating properties in multiple studies (Preethi et al., 2009). A strong calendula tea applied to a wound or used as a wound wash is a reasonable adjunct treatment. Grow it — it is easy to cultivate, flowers prolifically, and the petals can be dried for storage.

Plantain (Plantago major): the broadleaf weed found in nearly every disturbed soil in the Northern Hemisphere. Fresh leaves, chewed or mashed, can be applied directly as a poultice. Contains aucubin (anti-inflammatory) and allantoin (promotes cell proliferation). Traditional use across dozens of cultures. Not a substitute for irrigation and closure, but a reasonable wound cover when nothing else is available.

Bone Fractures and Splinting

Fractures are not life-threatening unless they involve major blood vessels (femur fractures can cause 1–2 liters of internal blood loss) or the spine. The priority is immobilization to prevent further injury.

Suspected fracture signs: pain, swelling, bruising, deformity, inability to bear weight or use the limb, and the sound or sensation of cracking at the time of injury.

Splinting principles:

• Immobilize the joint above and the joint below the suspected fracture.
• Pad the splint with soft material — blanket, clothing — to prevent pressure sores.
• The splint should be rigid (straight branch, board, tightly rolled sleeping pad) but the limb should not be forced into an unnatural position.
• Check circulation after splinting: press a fingernail or toenail until it blanches, then release — color should return in under 2 seconds. Check sensation and movement at the fingers or toes. If circulation is compromised, the splint is too tight.
• For leg fractures, improvised traction splints (for femur) require training to apply safely — immobilize in place and move carefully.

Open fractures (bone protruding through skin): cover with the cleanest dressing available, do not push the bone back in, irrigate the wound, splint, and evacuate to medical care if any is accessible. These are high-infection-risk injuries.

A Note on Scope

Nothing in this guide substitutes for hands-on medical training. The principles here — irrigate well, close only clean wounds, recognize infection early, use natural antimicrobials as adjuncts — are based on current evidence and historical practice. But medicine practiced on another person carries risk, and mistakes have consequences.

In any rebuilding community, training in wilderness medicine and maintaining a real medical kit (sutures, irrigation syringes, antiseptics, antibiotics if obtainable) is among the highest-value investments possible.
