Wound care when you are miles from anywhere

Cleaning water, carrying weight and a low threshold for turning back. Different rules apply.

Remote first aid changes the calculation. You have less kit, dirtier conditions and a longer route to help.

Carry water you can clean with

Sterile saline pods weigh very little and mean you are not irrigating a wound with stream water. If you have none, use water you would be willing to drink.

Prioritise by weight

  • Two large dressings beat twenty small ones for genuine emergencies.
  • Tape is the most versatile item per gram you can carry.
  • Gauze swabs double as cleaning, padding and pressure.
  • A conforming bandage secures anything.

Blisters are the real risk

Statistically you are far more likely to be stopped by a blister than a laceration. Carry tape and treat hotspots the moment you feel one.

Lower your threshold for turning back

A wound you would manage at home may not be manageable eight miles out in the wet. Contamination, cold and inability to keep a dressing dry all argue for heading in.

When to get medical help

See a pharmacist, GP or urgent care if a wound will not stop bleeding after ten minutes of firm pressure, is deep or gaping, was caused by something dirty or rusty, contains anything you cannot flush out, or shows spreading redness, heat, swelling, pus or a fever. Get help urgently for animal or human bites, wounds over a joint, and any wound in someone with diabetes or poor circulation.
