This guide is designed to empower you to act decisively and effectively, bridging the gap until professional medical help can be reached or the situation can be managed safely.

Wilderness First Aid Kit Essentials

Building a comprehensive wilderness first aid kit is paramount. Here’s a general overview; specific needs depend on the trip’s length, location, and group size.

• Bandages: Assorted sizes, sterile gauze pads, adhesive tape, triangular bandages (for slings), elastic bandages (Ace wraps).
• Wound Care: Antiseptic wipes/solution (povidone-iodine or chlorhexidine), antibiotic ointment, sterile irrigation solution (saline).
• Medications: Pain relievers (ibuprofen, acetaminophen), antihistamine (diphenhydramine), anti-diarrheal medication (loperamide), antiseptic solution.
• Tools: Trauma shears, tweezers, safety pins, thermometer, CPR mask, disposable gloves, irrigation syringe.
• Splinting Material: SAM splint or similar flexible splint, padding material (e.g., cotton roll or improvisational materials).
• Other: Moleskin (for blisters), sunscreen, insect repellent, water purification tablets/filter.

Treating Deep Cuts and Lacerations

Deep cuts pose a risk of significant blood loss and infection. Prompt and effective treatment is crucial.

Supplies Needed:

• Sterile gloves (1 pair)
• Antiseptic wipes/solution (4-6)
• Sterile gauze pads (assorted sizes, 4-6)
• Adhesive tape (1 roll)

• Optional: Sutures/Suture Kit, or Steri-Strips

Treatment Procedure:

1. Protect Yourself: Put on sterile gloves.
2. Control Bleeding: Apply direct pressure to the wound with a sterile gauze pad. Maintain pressure until bleeding stops. Elevate the injured limb if possible.
3. Clean the Wound: Thoroughly irrigate the wound with sterile saline solution using the irrigation syringe. Remove any visible debris. Clean the surrounding skin with antiseptic wipes.
4. Close the Wound: If the wound edges easily come together, use Steri-Strips to close the wound. If deep or gaping, consider using sutures (only if trained). Otherwise, pack with sterile gauze.
5. Dress the Wound: Cover the wound with a sterile gauze pad and secure it with adhesive tape.
6. Monitor for Infection: Check the wound regularly for signs of infection (redness, swelling, pus, increased pain, fever).

Improvisation:

• No Sterile Solution: Use clean drinking water that has been boiled and cooled.
• No Gauze: Use clean cloth, bandanas, or t-shirt material.
• No Tape: Use strips of cloth or duct tape (apply over gauze).

When to Evacuate:

• Uncontrollable bleeding despite direct pressure.
• Deep wounds involving tendons, nerves, or blood vessels.
• Signs of infection that worsen despite treatment.

Managing Fractures and Sprains
