Wilderness medicine is commonly low drama and routine problems: flu-like illness, mild/moderate stages of environmental problems, sore muscles, minor cuts and scrapes. Early intervention keeps these minor problems from becoming significant concerns. So much of sound wilderness medicine is also sound outdoor leadership.
When there is nothing obviously dire in the patient’s presentation, we consider the worst case, see if we can rule anything out, treat for multiple problems, and see if the patient gets better or worse. A worst case would be heat stroke, which is not apparent in this patient whose skin is not hot and who has normal mental status. The hydration history suggests that hyponatremia from drinking too much, or dehydration from drinking too little, are both unlikely.
Trends in vital signs are vital to assess. The first set establishes a baseline. Changes, or stability, are both important pieces of information. In this case the vital sign trend tells us the patient is stable and even improving. A HR that stays elevated or trends faster, with pale moist skin and perhaps a weakening radial pulse or altered mental status tells us something is going on, perhaps some form of shock. A patient who continues to complain of being weak and feeling ill is obviously not improving.
Maybe this is just a mild flu-like illness, low blood sugar, or fatigue from the heat. We often treat for multiple problems at the same time, throwing a wide net over the problem. Heat stress and possible dehydration are managed by seeking shade, resting, and supporting hydration, which also treats a possible flu-like illness. If our net doesn’t help the patient get better, we evacuate.
The patient felt much better within a few hours and wanted to get on down the trail, but the group decided to move only a short distance to a nicer campsite for the night. In the morning the patient, well-hydrated, rested and fed, was able to resume the hike.
Patience with our patients is a virtue in wilderness medicine. We want to fix problems quickly, yet we often get ill slowly, and better slowly. One of the traps of the short scenarios common in wilderness medicine courses is the illusion that people get better quickly. People may be physically in wilderness, but often act like they are in a city, with expectations for quick solutions to inconveniences, let alone real problems. This group acted as if they were in the wilderness. They changed their plans, stopped the hike, rested, and cared for their companion.
