1. Baby wipes
Say hello to your go-to cleaner-uppers, great for cleaning your hands or a muddy scrape, says Wendy Sue Swanson, M.D., a mother of two and a pediatrician at Seattle Children's Hospital.
2. Hand towel
Unfurl it to create a clean surface for laying out supplies, or roll it up to stanch large bleeding wounds. Plus, says Kathleen Berchelmann, M.D., a pediatrician at St. Louis Children's Hospital, "helping kids tends to involve vomit; a towel helps with that, too!"
3. Kiddie pack
Little-known fact: Fun treats can not only make boo-boos seem to hurt less, but also stop kids from squirming – allowing you to take out those splinters! Easy options: bubbles, stickers, or character bandages.
4. Info card
Write your family's insurance info, birth dates, allergies, medications, and health conditions on an index card and plunk it into a plastic sandwich bag. Brownie points if you add phone numbers for poison control, your doctor, and an emergency .
5. Blister pads
Look for a box that says "hydrocolloid" on the label. You can put them on any blister, even if raw skin is exposed, to "cut down on friction," says John Vonhof, a former paramedic and author of .
6. Garbage bag
Use it to cover a splinted limb, as a receptacle for bloody garbage, or as a poncho (cut a hole for the head) when someone is hypothermic — such as when a swimmer stays in the water too long, says Tod Schimelpfenig, a wilderness EMT.
7. Afrin nasal spray
If you've still got a bloody nose after having pinched your nostrils shut for 10 minutes, spritz with this. The active ingredient, oxymetazoline, constricts blood vessels and in turn halts the flow.
8. Temporary dental filling
This putty molds to a damaged tooth, sealing it from the air and easing ache, says Christopher Van Tilburg, M.D., a specialist in adventure-travel medicine. Roll a bit into a ball, place it on the tooth, and bite down firmly for a minute. See a dentist within a week or sooner if pain persists.
9. Store-bought water bottle with squeeze nozzle
It will guarantee that you have fresh water to clean a wound. Plus, the nozzle provides the oomph needed to flush dirt and debris, says Dr. Berchelmann. To use, simply hold the bottle a few inches from the wound and squeeze firmly.
10. Quart-size resealable bag
Add ice, and presto: cold pack. It can also serve as a disposable glove or (eek!) a carrying case for an amputated finger or toe, says Jeffrey Pellegrino, Ph.D., a member of the Red Cross Scientific Advisory Council. (In the latter case, rinse digit and wrap in gauze; place the bag — not the digit itself! — in cold water en route.)
