Wilderness First Aid

The best wilderness first aid success story Mike Webster tells is about the climbing instructor who took charge of her own care after falling on the side of a mountain when her cord got loose.

“I find that case remarkable because she was the guide with the training, but told everybody else what to do [for her own care],” says Webster, a paramedic, expedition medic and Canadian executive director of Wilderness Medical Associates (WMA). By assessing the situation, she was able to get her clients—now her rescuers—to immobilize her properly and evacuate her successfully. And while she sustained multiple fractures to her vertebrae, says Webster, by staying calm that day on the mountain, and with good hospital care, she was able to make a full recovery.

Before embarking on any trip that involves remote locations or risky activities—and canoeing, camping and trekking all qualify—consider getting trained in wilderness first aid, which may be your best bet at keeping an unexpected situation from becoming life-threatening.

According to the National Search and Rescue Program, rescue workers responded to 8,015 incidents in Canada in 2005. While the vast majority were water rescues—with human error cited in half the cases—there were also 748 non-marine “requests for assistance” requiring medical evacuation or transportation services.

Unlike standard first aid, which is designed for an urban setting where help is minutes away, Webster defines wilderness first aid as patient care that’s determined by three distinct factors: time, resources and environment.

How far are you from proper medical care? Resources, or “really the lack of,” says Webster, is about the equipment, medicines and supplies you have to treat a person at the time of injury. And environment refers to the terrain, weather and access to shelter that impact your decision on what action to take, including whether to evacuate or bring help in.

Overall, caring for an injured person in the wilderness is about doing what makes sense for the situation.

  • How do you do that? Start by staying calm, not moving the patient (unless in imminent danger), and asking a few simple questions:
  • How serious does the injury appear?
  • Are they conscious?
  • Is the head, neck or spine involved?
  • What can, and can’t, the patient do?
  • Can they move the injured part body; stand up, walk or bear weight; flex or extend an ankle; push down when you apply pressure on the bottom of their foot?

For bone, muscle and joint injuries, the Canadian Red Cross recommends the RICE method: rest, immobilize, cold and elevate.

In the wilderness, where the need to evacuate means resting the limb isn’t always possible, applying ice (which reduces inflammation and swelling), and immobilizing the injury in a splint, are most important. A splint is any device that keeps an injured part secure, and can be purchased before a trip or improvised in the wild. Tree branches, rolled up sleeping bags, blankets or tents, and poles or paddles, are all possibilities, as long as you follow the WMA’s “3Cs” of splinting: comfort, compact and complete. An improvised splint must be comfortable enough to be in use for hours or days, so watch for knots and areas that cause chafing or sweating. Make it snug, with enough padding to absorb movement, but not so tight or cumbersome that it impedes evacuation. If a limb is contorted, the WMA recommends straightening before splinting (if not too painful) as a contorted limb can cut off blood flow and damage extremities. This can also relieve pain since the limb is put into its anatomical position. (Ibuprophen or acetaminophen is best here for pain relief.) It’s important to splint above and below the fracture site.

How do you differentiate between a fracture and a sprain?

Without access to an X-ray, says Webster, you can’t, which means relying on other assessment tools. Pain is one—though keep in mind some injuries involve nerve tissue, which make them more painful than they may be severe. (The opposite is also true!) If the patient is conscious or can bear weight—even if in pain—the WMA advises it’s best to evacuate them with you. Conversely, if an injury appears stable—isn’t likely to get worse over time, is not a head injury and doesn’t appear infected—leaving someone warm and hydrated at camp isn’t a big issue. Check toes, fingers and skin around the injury for feeling and colour, a sign that circulation is good and blood is getting to the extremities.

But if the injury may worsen in the next few hours (or you don’t know if that’ll happen), lean toward getting them out and to a hospital. “We do what makes sense,” says Webster, and leaving an injured person often doesn’t, particularly if they’re alone. Why—because they’re at the whim of the elements and it takes enormous effort to bring someone in. (In the Grand Canyon, where Webster worked as a rescuer, it could take 15 people to evacuate one person just a few kilometres.) “If it’s three days before you can get back, you have to determine if the person is well enough to take care of themselves. If not, that’s a problem.”

With spinal or head injuries there are no easy answers—the fear of having to face one could be the best incentive yet to learn wilderness first aid. Getting the patient to a hospital as quickly and carefully as possible makes most sense. Back-boarding a patient—rolling them onto a board to immobilize the injury and carry them out—isn’t always possible. But if it is, do it. Whatever action you take, ensure the back and head remain immobile when moving the patient.

It’s worth noting how many wilderness injuries result from simple gestures or repetitive actions. Too much paddling can cause muscle strain; trekking in shoes without solid support can easily trip you up. And be wary of all that equipment you bring, says Webster—a pocketknife, axe, stove—all are accidents waiting to happen.

Wound Care

  • Stop bleeding by applying direct pressure for extended period.
  • Irrigate with purified water to clean out dirt and microbes.
  • For disinfecting a deep wound and its cavity, use only iodine 1% (povidone iodine, or dilute with water if too strong); never use alcohol or hydrogen peroxide as they can kill healthy tissue needed for healing.
  • Never self-suture a wound—this seals in harmful bacteria.
  • For deep wounds, cover with gauze dampened with clean water or iodine; change frequently.
  • Watch for heat, redness or red streaks—signs of growing infection or blood poisoning.
