If you’ve got time before you go, get hold of the Jim Duff book (‘Pocket First Aid and Wilderness Medicine’) and give that a read before buying any kit.
SAM Splints are brilliant, just about every rucksack I own has one or two stuck down the back.
Don’t just end up with a massive booboo kit – plasters are a nicety, but an Israeli dressing can save a life. That said steristrips and superglue weigh next to nothing.
Things people tend not to think about until it’s too late:
– keep gloves accessible (not buried) and in the right size(s)
– have some plain gauze for soaking up assorted liquids
– pen/sharpy and paper handy
You don’t need to use saline for cleaning wounds, bottled (or definitely clean) water is fine with an empty syringe for irrigation.
Go for the newer quikclot/celox gauze (if you’re that way inclined) rather than powder as compressing a wound is still the most important thing. Just watch that Cedric Gracia video 8O
As above be wary of prescription meds unless above-board. Don’t underestimate simple paracetamol and brufen for pain relief.
Carry a roll of duct tape.
