I think tOM is the first one to mention the absolutely most important thing in first-aid for dunked electronic/electrical equipment of any kind:
GET **ALL** BATTERIES OUT OF IT THE VERY FIRST THING YOU DO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Not only the main batteries, but any backup ones as well... As long as there is a voltage applied between submerged or wet metals anywhere, you´ll get electrolysis that severely aggravates any corrosion, and can ruin the equipment in a very short time. Most people know that leaking batteries means quick disaster; this is equally lethal!
After that, it is "safe" to re-dunk the poor thing in pure water until it gets professional help.

My understanding for this sort of thing is that, upon drowning, remove any
batteries and keep the poor camera in fresh, preferably distilled, water until
you get to the repairer.
If drowned in salt water, flush gently and repeatedly with fresh water before
you carry it to your repairer.
Keeping it in the water reduces corrosion and prevents any river gunk from
drying out and sticking hard to things.
