Wound Care Without Hospitals

Wound infection is the primary killer after injury when hospital care is unavailable. Most wound deaths are preventable through aggressive early cleaning and appropriate closure decisions - choosing when not to close a wound is as important as knowing how.

Key Concepts

• —Wound cleaning as the primary intervention: thorough irrigation with clean water under pressure removes bacterial load by several orders of magnitude; no antiseptic or antibiotic compensates for inadequate cleaning.
• —Primary versus delayed closure: clean wounds seen within six hours can be closed; contaminated wounds, animal bites, and wounds seen after six hours should be left open and closed after three to five days once infection risk has passed.
• —Signs of infection: increasing redness, warmth, swelling, and pain after the first 24 hours, plus pus, red streaks, or fever, indicate infection requiring drainage and possibly systemic treatment.
• —Antiseptic options: dilute povidone-iodine (1%), dilute hydrogen peroxide (3% used once, not repeatedly), and honey are the most accessible and effective wound antiseptics in austere environments.
• —Wound closure methods: skin closure strips or improvised butterfly bandages from adhesive tape hold edges together without penetrating the skin; sutures and staples create a stronger closure but carry higher infection risk if the wound is not clean.

Practical Guide

1. 1.Control bleeding first with direct pressure for at least ten minutes; do not assess the wound fully until hemostasis is established, as irrigation and exploration cannot be done safely on an actively bleeding wound.
2. 2.Irrigate the wound with at least 500 ml of clean water using a 20 ml syringe or a plastic bag with a small hole; the water jet must be strong enough to dislodge debris - gentle pouring is not adequate.
3. 3.Remove all visible foreign material (gravel, wood, fabric fibers) with clean tweezers under good lighting; material left in a wound will cause chronic infection regardless of antibiotic treatment.
4. 4.Apply dilute povidone-iodine or raw honey to the wound bed before dressing; raw honey has documented antimicrobial activity against most common wound pathogens including antibiotic-resistant strains.
5. 5.For wounds that can be closed: approximate (bring together) skin edges using skin closure strips or butterfly bandages; do not close wounds tighter than needed - leaving small gaps allows drainage.
6. 6.Dress with a clean, absorbent layer held in place with bandage; change dressings daily (or when saturated), irrigating again at each change until the wound shows signs of clean healing.
7. 7.Watch for and act on red streaks extending from the wound - this is lymphangitis (spreading infection) and requires systemic antimicrobial treatment, elevation, rest, and urgent care if available.
