Hydrogen peroxide is routinely used for cleaning abrasions and lacerations at athletic events where I work or volunteer. We use 3% H2O2 to help clean and debride the wounds, prior to dressing and bandaging (typically with Telfa non-stick pads and triple-antibiotic ointment). But I've heard some nurses comment that they don't like using H2O2 on wounds, since it is toxic to cells involved in the wound-healing process, and delays healing. They would prefer to use saline for the cleaning chores. I did some googling, and found some good articles. This is one (I haven't read the whole article yet): Wound Care Management: Proper Protocol Differs From Athletic Trainers' Perceptions I also got an interesting question from a spectator at an event yesterday where I volunteered as an EMT -- "If you had a person with a laceration that was going to be sutured, would you clean it with hydrogen peroxide before suturing?" I think their question came from the cell damage issue raised in the link. Does anybody know the answer? Thanks.
