Multicenter Study Controlled Clinical TrialThe impact of noncontact, nonthermal, low-frequency ultrasound on bacterial counts in experimental and chronic wounds.
Preventing wound infection and the development of resistant bacteria are important concerns in wound management. To determine if noncontact, nonthermal, low-frequency ultrasound therapy is effective in controlling wound bacterial colony counts, a series of four related experiments was conducted. First, ultrasound penetration in both wounded and intact skin was assessed in vitro. ⋯ None of the wounds exhibited signs of a clinical infection during the treatment period and no adverse events were observed. Taken together, these four studies indicate that noncontact ultrasound can be used to reduce bacterial quantity. Controlled clinical studies are warranted to ascertain the efficacy of this treatment and to further elucidate its effects on various Gram-negative and Gram-positive bacteria.
