“Its low pH is not compatible with certain bacteria like Pseudomonas,” meaning it can be effective against this common disease-causing pathogen. “There is science behind using common distilled vinegar, even though most people don’t consider it,” he said. “Its antimicrobial properties are probably greatly overestimated,” said Hendrickson. Popular for its effervescent activity, which can convince the user it’s thoroughly working, hydrogen peroxide has few beneficial or negative effects. ![]() It also causes tissue necrosis and bacteria regrowth, he said. Hendrickson explained that chlorhexidine has low systemic toxicity, but studies have shown little evidence of its safety and efficacy reducing bacterial numbers without causing wound trauma. “Consequently, PI should only be used around the wound over intact skin and never in the wound itself,” he said. ![]() While povidone iodine has been used extensively in equine wound care, Hendrickson cited several studies showing that it causes tissue necrosis, impairs healing, and leads to increased infection. It does have the ability to damage normal cells, as well, he cautioned, so use it only in infected wounds. Hypertonic saline, in particular, is very effective for debriding (removing surrounding dead, damaged, or infected tissue) while lavaging and for reducing bacteria in the wound. Hendrickson referenced saline again and again throughout his presentation as one of the most simple, yet effective, wound-cleaning agents. Hendrickson then delved into the common topical treatments we apply to wounds and which ones are safe to use. Again, don’t use much pressure a gentle showerhead-type sprayer works well. One approach is saline lavage to remove surface debris-“One of the best things we do,” he said. “If gentle scrubbing doesn’t work, use a different technique,” said Hendrickson. Then, use sterile gauze to very gently scrub the wound. In other words, ask yourself: Is that cleaning agent ultimately going to speed up or retard wound-healing?īefore applying anything, however, clip the hair around the wound to prevent it from contaminating the area. “Weigh the benefits of cleaning the wound against the trauma that agent will cause.” ![]() Although our intentions are good, “most wound-cleaning agents and techniques will cause chemical or mechanical trauma to the wound bed,” he said.
