I don't know if you carry these in your regular FAK, but in light of my recent experience (http://forums.equipped.org/ubbthreads.php?ubb=showflat&Number=208790&gonew=1#UNREAD)
I would suggest adding a couple of trauma pads, a roll of gauze, and a roll of waterproof/stretchy tape to your wound care kit.

Also, if you're anything like me, adding a chemical cold pack to counter the adrenaline surge to your wound care kit makes patching yourself up easier.
