How do you sterilize a puncture wound?

You first wash out the area with warm, soapy water. Then you can apply disinfecting wipes. Rubbing alcohol works too. If it is serious, call 911.t

Try to stop the bleeding by using a sterilized gauze pad or tourniquet. You can use Neosporin or some kind of topical antibiotic ointment; Betadine Solution, an over the counter solution of 10% povidone-iodine in water; hydrogen peroxide; or rubbing alcohol. Decide whether a butterfly bandaid or stitches are needed.

Puncture wounds that are caused by rusty metal (like a nail) or an animal warrant a visit to a hospital emergency room. So if you can, drive yourself or get a ride to the ER. If the wound was caused by a rusty metal, get a tetanus shot or booster tetanus shot, stitches (if needed), and an antibiotic prescription to prevent systemic spread of infection.
