I would advise caution in the use of Hydrogen Peroxide in treating wounds. I would certainly irrigate the wound afterward with sterile normal saline to remove any peroxide.
While I cannot verify reports from the Vietnam War that peroxide caused significant increase in wound infections in that environment, there is certainly some evidence that this is quite possible. This article, from "EMERGENCY MEDICINE®: The Practice Journal for Emergency Physicians is a monthly journal for emergency physicians and physicians working in urgent care settings." says:
http://www.emedmag.com/ht[...]804.asp
"The major error here, of course, was committed by the surgical resident who, for some unfathomable reason, decided to use hydrogen peroxide as an irrigating solution. Hydrogen peroxide solutions are corrosive and can cause tissue necrosis. In addition, they release oxygen into the tissues when they come in contact with peroxidases and hemoglobin.
The only irrigating solution that has been shown to be effective and relatively innocuous is normal saline. Almost any other foreign substance that is placed in a wound can delay healing and damage granulating wounds. This includes undiluted iodophor solutions. As a general rule, if the substance cannot be used in the eye, it should not be introduced into wounds.
Iodophors are appropriate for skin preparation, not wound cleansing. The body's capacity for wound healing is generally so great that the negative effects of an irrigating fluid are trivial compared with this natural ability. However, when a wound contains a large inoculum of bacteria or a significant amount of devitalized tissue, or when there is impaired circulation to the wound site, use of an unphysiologic irrigating fluid can tip the scale, leading to infections and dehiscences. "
It is important to understand that medicine is a dynamic field and theories go in and out of practice as new studies are made. One might consider that in a hot, moist environment adding additional oxidizer to the mix could create an ideal environment for bacterial growth. It can also inhibit healing because it has a sort of corrosive effect on the delicate body tissues. I have seen articles by wound nurses that say not to use it.
This is not to say that all the suggestions above are invalid. Nurses used to clean blood from their whites with peroxide and then wash them (often with ZOUT, which is still available.) I used it to clean my earrings, but it can oxidize some finishes, like silver.so I would not risk it.
Ultrasonics can clean jewelry safely but untrasonic cleaning of teeth can make your fillings fall out.. So use caution when adopting clever new uses for things.

Hi Karen,
When I saw the name of the thread I thought it would be about hair coloring.....
Thanks for the info. I've used hydrogen peroxide to soften ear wax for years.
Best,
Melody
