The items below are merely suggestions about what would work well in a canoe first aid kit. It is vitally important to keep your first aid kit clean and dry so even if you have a waterproof container to hold all your first aid gear I suggest placing items into ziplock bags inside of the waterproof container. That way you know the items are fresh and any item that has been used is open so it can be replaced.
# 1 Waterproof container
# 1 Antibacterial soap
# 1 Bottle Betadine or Iodine for cleaning wounds
# 1 Pkg of various sized bandaids.
# 2 Tubes anti-bacterial ointment (Bacitracin, etc. for lacerations and wounds)
# 18 Various sizes butterfly band-aids (for closing lacerations)
# 2 Elastic bandages (3 inch) (for sprains and securing splints)
# 18 Steri-pad gauze pads (4 inch by 4 inch) (for large wounds)
# 18 Steri-pad gauze pads (2 inch by 2 inch) (for smaller wounds)
# 2 Waterproof adhesive taps (2 inch) (for sprains and securing dressings)
# 4 Triangular bandage (for securing rigid splints, slings, or protecting dressings)
# 2 Rolls roller gauze
# 1 Small pocket knife
There are many items that you could add to this list so feel free to modify your individual canoe first-aid kits.
