I was on an outdoors-focussed first-aid refresher course at the weekend, so this is... er... fresh in my mind.
Apart from the usual stuff such as checking for hazards and other wounds, the advice is as per several folks above:
Priorities:
- Cool the burn
- Keep the burn sterile
The first priority is to cool the wound under running water for ten minutes (even if the only water available is a muddy stream, immediate cooling trumps being sterile), failing that, use whatever is to hand; milk, coke, or other cool liquid is better than nothing.
Remove any rings, watches, wristbands, which may cause constriction if the injury swells.
Cover the cooled burn using a
sterile non-adhesive dressing and cover that with cling film, if available. Cling film can be used as the primary dressing as it won't stick to a cool burn and is likely to be sterile
if unopened, but if there is
any doubt, it is better to dress with a known sterile dressing and use the cling film to wrap over the dressing to keep dirt out.
- DO NOT touch the burn
- DO NOT burst any blister
- DO NOT use any creams, ointments, balms, etc.
- DO NOT attempt to remove clothing which has stuck to burn (apply dressing over stuck clothing).
Immediate medical treatment is essential if:
- the burn is larger than a 50p (or one inch square)
- the burn is to the palm of hand or sole of foot
- the burn is to the groin or above the shoulder
- the patient is a child.
Depending on the severity of the burn, other general considerations include to check the patient every few minutes for stress reactions (‘shock’
, and not to leave the patient alone.
EDIT: It probably goes without saying, but "don't touch the burn" also means don't try to remove ash, cinders, etc. which don't come away with the cooling water.
Also, Totempole's point (see message above) is really useful about checking for indications that there may be damage to the airway.
