Outdoor First Aid Kit Configuration Guide: Medications & Equipment

1. First Aid Kit Configuration Principles

Three Core Principles

1. Configure based on activity type: A day hike ≠ high altitude ≠ jungle trekking
2. Only bring what you know how to use: Medications you can't use are better left behind
3. Regularly check and update: Expired medications are useless; consumables need timely replenishment

Volume and Weight Control

• Day hike: 100-200g mini kit
• Multi-day trek: 200-400g standard kit
• High altitude / Expedition: 400-800g expanded kit

2. Basic Configuration (Essential for All Outdoor Activities)

Wound Care

Item	Quantity	Use
Iodine swab sticks	10 sticks	Disinfection (gentler than alcohol, doesn't sting wounds)
Band-aids (various sizes)	10 pieces	Cover small wounds
Sterile gauze	2-3 packs	Cover medium wounds
Medical tape	1 roll	Secure gauze
Elastic bandage	1 roll	Pressure bandage / Sprain immobilization
Triangular bandage	1 piece	Sling / Large area bandaging

Bleeding Control & Swelling

Item	Quantity	Use
Hemostatic powder / Hemostatic sponge	1-2 packs	Assist in stopping severe bleeding
Yunnan Baiyao spray	1 small bottle	Reduce swelling and pain from sprains
Cold pack	2 pieces	Immediate cold compress for sprains

Protective Gear

Item	Quantity	Use
Medical gloves	2 pairs	Protection when treating wounds
Face mask	2 pieces	CPR / Protection
Tweezers	1 pair	Remove splinters / debris
Small scissors	1 pair	Cut gauze / tape

3. Advanced Configuration (Multi-day / Moderate to High Difficulty Activities)

Common Medications

Medication	Use	Notes
Ibuprofen	Fever reduction / Pain relief / Anti-inflammatory	Take after meals; do not exceed 1.2g/day
Acetaminophen	Fever reduction / Pain relief	Do not exceed 2g/day; do not consume with alcohol
Montmorillonite powder	Acute diarrhea	Take on an empty stomach
Oral rehydration salts	Replenish electrolytes for diarrhea / dehydration	Mix according to package instructions
Loratadine	Allergic reactions	Side effect: drowsiness
Erythromycin ointment	Skin infections / Abrasions	For external use only
Dramamine / Motion sickness medication	Motion sickness	Take 30 minutes before departure

Advanced Wound Care

Item	Use
Wound closure strips (butterfly strips)	Suture-free closure for deeper wounds
Blister bandages	Treat blisters on long hikes
Medical cotton swabs	Clean wounds
Saline solution	Flush wounds (cleaner than tap water)

Fracture / Sprain Management

Item	Use
SAM splint (malleable aluminum splint)	Temporary immobilization for limb fractures → bendable for shaping
Triangular bandage	Sling for injured limb
Elastic bandage	Figure-8 wrap for sprains

4. Special Environment Configuration

High Altitude Activities

Item	Use	Notes
Acetazolamide (Diamox)	Prevent / Treat Acute Mountain Sickness (AMS)	Requires starting 1-2 days before ascent for prevention → Prescription needed
Dexamethasone	Emergency treatment for High Altitude Cerebral Edema (HACE)	Emergency use only → Descend immediately
Nifedipine	Emergency treatment for High Altitude Pulmonary Edema (HAPE)	Emergency use only → Descend immediately
Portable oxygen	Acute hypoxia	Small canister 4-6L → Temporary relief → Still requires descent

⚠️ The most important treatment for high altitude is descent! Medications only buy time!

Jungle / Tropical Activities

Item	Use
Antimalarials (region-specific)	Malaria prevention
Jidesheng snake venom antidote	Adjunctive treatment for snake bites (NOT a substitute for antivenom)
Insect repellent (DEET 30%+)	Prevent mosquito bites
Calamine lotion	Relieve itching from insect bites

Cold Environment

Item	Use
Emergency blanket (mylar)	Hypothermia rescue → Wrap body to reflect heat
Chemical hand warmers	Localized warmth / Prevent frostbite from worsening
Glucose tablets / gel	Emergency treatment for hypoglycemia

5. Common Outdoor First Aid Procedures

Sprain Management (RICE Principle)

1. R (Rest): Stop the activity
2. I (Ice): Apply cold compress for 15-20 minutes → Rest for 30 minutes before reapplying
3. C (Compression): Apply pressure bandage with elastic bandage → Not too tight → Distal extremity turning purple = too tight
4. E (Elevation): Elevate the injured limb → Reduce swelling

Bleeding Control

1. Direct pressure: Press gauze directly on the wound → Do not release for 10 minutes
2. Pressure bandage: Gauze + elastic bandage → Maintain continuous pressure
3. Tourniquet: Only for arterial hemorrhage in limbs → When other methods fail → Note the application time → Exceeding 2 hours may lead to amputation

Snake Bite Management

1. Stay calm → Reduce activity → Slow venom spread
2. Remember the snake's appearance → Helps select the correct antivenom
3. Apply an elastic bandage from the proximal end of the bite towards the distal end → Not too tight
4. ❌ Do NOT cut the wound → Do NOT suck the venom with your mouth → Do NOT apply ice → Do NOT drink alcohol
5. Seek medical attention immediately → Antivenom is the only effective treatment

Hypothermia Management

1. Mild (shivering, conscious): Remove wet clothing → Wrap in emergency blanket → Warm drinks / food
2. Moderate (shivering stops, confused): Above + chemical warmers (armpits / groin) → Avoid rough movement
3. Severe (unconscious): Handle with extreme care → Insulate → Do not attempt rapid rewarming → Call for emergency help

6. First Aid Kit Storage & Management

Storage Suggestions

• Waterproof bag: Store all items in a waterproof bag → Essential for humid outdoor environments
• Compartmentalized storage: Sort by function into small pouches → No frantic searching in an emergency
• Attach a checklist to the outside: Know exactly what's inside at a glance

Regular Maintenance

• Every 3 months: Check medication expiration dates → Replace expired items
• After each activity: Replenish consumables
• After summer: Check medications sensitive to high temperatures (e.g., sprays, ointments) → May have degraded

Learning Suggestions

• First aid knowledge is more important than the first aid kit itself:
  • Take a Red Cross first aid training course (1 day)
  • Learn a WFA (Wilderness First Aid) course (2 days)
  • Master CPR (Cardiopulmonary Resuscitation) and AED use
• Do not bring medications you don't know how to use → Using them incorrectly is more dangerous than not using them

A first aid kit is not just a decoration; it's life-saving equipment in a critical moment. But remember: the best first aid is prevention — sensible route planning, adequate physical preparation, and correct risk assessment are always more important than post-incident remedies!
