I'm a Ski Patroller, certified in Outdoor Emergency Care, Mountain Travel and Rescue, and Red Cross Professional CPR. I recently graduated from the National Outdoor Leadership Wilderness First Aid course. (Which I highly recommend to any venturing away from immediate EMT support). While I want this kit to be as light as practical to keep the pounds off my old knees, I also want to be prepared for what might befall us. I decided to assess the risks, figure out what I needed to address the most likely issues, and to think thru what can be improvised by using what's in one's pack or on the ground around them.
What are the risks? Hiking in the mountains, there's lots of injuries from falls. Mostly from trips, but potentially worst - sprained ankles, broken bones. General aches and pains. Blisters. Stress fractures. Bug bites, ticks bites / Lyme disease. There's snakes out there, but bites are relatively rare. Cuts from mishandled knives. Burns from spilled cook pots. Poison ivy. Stomach nastiness from poor hygiene practices or from drinking unfiltered water. Hypothermia. Worst case scenarios would be a cardio-vascular emergency, or a fall with possible spine or head injury. On the other hand, any point on the Appalachian Trail, is usually no more than a few days away from a hospital. Cell phone coverage is pretty good, and a SAR / helo extraction can be activated if necessary.
Many of the companies selling first aid kits for backpacking, classify them by the number in the group and the length of the trip. Most are packed in clever, but heavy, fold-out nylon pouches that weigh well over a pound. Adventure Medical Kits is now producing an UltraLight line for backpackers, packed in tough, waterproof pouches, that are pretty well outfitted. If you're hiking solo, and not trained in first aid, their Ultra/Watertight .3 or .5 kits are good options.
I didn't find one that had the mixture of tools, bandages and meds I wanted, at a weight I found acceptable. I decided to build my own.
Whiteblaze.net is an outstanding reference resource for those preparing to hike the Appalachian Trail. There's an article on first-aid kits for backpackers written by a nurse. Between her article, the comments following it, the Wilderness First Aid course I took, and my own experience, I came up with what I thought was a pretty good list to address the risks I identified:
Motrin (small bottle kept handy in pack) - for inflammation and pain.
Tylenol (a couple of 2 packs) - Pain with bleeding. (cuts, open fractures)
Aspirin (2 pack) - To chew up if the ticker decides to stop beating
Imodium A D (Loperamide) (6 pack) - Because diarrhea is miserable, and can get serious
Benadryl (Diphenhydramine) - Allergies, insect bites, bee strings, itchiness, sleep aid
Hydrocortisone Cream (2.5%) - Localized rashes, itches, poison ivy
Spenco 2nd Skin Adhesive Knit (4 - 3" x 5") - A thin, breathable moleskin for prevention
Splint materials - Found in nature - Sticks, backpack stays, etc., held with duct tape
Sling - Bandana (a true multi-use item). Make a large one that'll make a good sling
Nitrile gloves (2 pr) - Protect me from you, and you from me
BZK Antiseptic Towelettes - To cleanse and disinfect small scrapes and cuts
Bandaids (various sizes)
Steri-Strip Skin Closure (3 packs of 5 - 3" x 1/8") Closing deep cuts
Transparent semi-permeable dressings (2 3/8 x 2 3/4 & 4" x 4 3/4") For deep cuts
Spenco 2nd Skin Moist Burn Pads (2 - 2" x 3") for when I spill my cook pot on my hand
Gauze pads (4-2x2, 3-4x4) Cleaning and dressing wounds
Adhesive Tape (1 - 1" roll) - Bandaging and wrapping sprains
Rolled gauze Bandage (1 roll) Bandaging wounds
Antibiotic Ointment (Neosprin, Bacitracin) - Treat small cuts and scrapes
Tweezers - A long, skinny, sharp pair - For splinters and ticks
Heavy-duty needle - To puncture and drain blisters, and sew torn clothes and gear
Small pair of sharp, pointed scissors to cut bandages, moleskin, and clean up blisters.
Syringe - To irrigate deep cuts and scrapes
Space Blanket - Keep patient warm, line sleeping bag in extreme cold.
Razor blade - For when you need a sharp blade
Tincture of Benzoin (1 oz) - An adhesive for moleskin, steristrips and bandages
One gallon sized baggie - Disposal of used bandages, gloves, and other bio-hazard stuff
I got some of the meds from REI. They come in the kinds of two packs you see in convenience stores, but in lots of 10. I put a couple each in my kit. I got a generic version of Imodium, and put a blister sheet of six in the kit. I figure if you need, em, you'll need more than two.
Given the prevalence of deer ticks in the Mid-Atlantic and New England portions of the trail, and that reports of hikers contracting Lyme are becoming all too common, I'm considering consulting with my GP about a script for four days worth of doxycycline to get me to an ER after symptoms show. Call me paranoid ... At the very least, we'll be treating our clothing with Permethrin, our bodies with DEET, and conducting thorough tick checks daily when we get into those parts.
I'd also be inclined to pack a small qty of some kind of prescription-strength acetaminophen/codeine combo for extreme pain.
I got the Spenco products, SteriStrips, and antiseptic wipes from Amazon, Some of the wound dressings came from Wilderness Medical Institute's store. Amazon carries them, but you have to by enough to outfit an ER. Again, just a couple of each went into the kit. The extra meds and bandages will be spread out amongst our drop boxes to resupply the kit.
I used snack-sized baggies to organize tools, blister stuff, wound stuff, meds, and bandaids, and I managed to squeeze it all into a one-quart freezer baggie. Total weight is 13 ozs.
I could reduce weight by reducing the qty of some of the bandages. Maybe eliminating some altogether. I could swap out the 1 oz bottle of Benzoin with ampules available thru Amazon, Eliminate the snack-sized baggies I use to organize the kit. Replace the half tube of triple antibiotic ointment with some of those small foil packets. Get rid of the syringe and use a water bottle to irrigate wounds ...
Maybe I will. I have five months to go. Of course, I already got rid of the EMT shears, sam splint, CPR mask ...
A lot of first aid kits come with a book. I downloaded NOLS Wilderness Medicine from Amazon, and loaded it on my Droid. Now that's a weight savings!
I really want to put those EMT shears back ...
Note: I have since updated this kit and wrote about it [here]
