Chronic non healing wounds have an elevated alkaline environment. The acidic pH of Manuka honey makes it a potential treatment for lowering wound pH, but the duration of effect is unknown. Lowering wound pH can potentially reduce protease activity, increase fibroblast activity and increase oxygen release consequently aiding wound healing. ⋯ The use of Manuka honey dressings was associated with a statistically significant decrease in wound pH and a reduction in wound size. Elevated pH readings at the start were associated with minimal reduction in size. Surface wound pH measurements may contribute to objective wound assessments, but further research is necessary to determine its exact contribution.

Multicenter Study
Dressing-related pain in patients with chronic wounds: an international patient perspective.
This cross-sectional international survey assessed patients' perceptions of their wound pain. A total of 2018 patients (57% female) from 15 different countries with a mean age of 68.6 years (SD = 15.4) participated. The wounds were categorised into ten different types with a mean wound duration of 19.6 months (SD = 51.8). ⋯ During the stages of the dressing change procedure; 'touching/handling the wound' was given the highest mean score of 2.9, followed by cleansing and dressing removal (n= 1944). One thousand four hundred and eighty-five (80.15%) patients responded that they liked to be actively involved in their dressing changes, 1141 (58.15%) responded that they were concerned about the long-term side-effects of medication, 790 (40.3%) of patient indicated that the pain at dressing change was the worst part of living with a wound. This study adds substantially to our knowledge of how patients experience wound pain and gives us the opportunity to explore cultural differences in more detail.

Randomized Controlled Trial
A prospective randomised controlled clinical trial comparing hydrosurgery debridement with conventional surgical debridement in lower extremity ulcers.
Debridement of devitalised tissue is an essential component of the effective treatment of chronic wounds. The Versajet Hydrosurgery System is a new technology that simultaneously cuts and aspirates soft tissue. In this study we compared Versajet with conventional surgical techniques in the debridement of lower extremity ulcers to assess impact on time and resources for debridement. ⋯ Overall, clinical efficacy of the shorter debridement procedure was similar: median time to wound closure 71 days (Versajet) vs. 74 days (conventional) (P= 0.733). We found Versajet to be quicker than conventional debridement in the debridement of lower extremity ulcers without compromising wound healing. Potential cost savings were identified from the use of VERSAJET through the shorter debridement time allowing more patients to be treated in the same operating schedule.

Pin tract infection is one of the most common complications associated with the use of external fixation. While some studies have identified the potential benefit of chlorhexidine gluconate-impregnated polyurethane dressings to reduce the incidence of catheter-related bloodstream infections, we are unaware of any published studies that evaluate the effectiveness of similar technologies in reducing the risk for external-fixation-related pin tract infections. Therefore, the purpose of this study was to evaluate the effectiveness of chlorhexidine gluconate-impregnated polyurethane dressing in reducing percutaneous-device-related skin colonisation and local infections. ⋯ There was a significantly higher rate of pin tract infection in patients who received standard pin care compared with those who received chlorhexidine gluconate-impregnated polyurethane dressings (25% versus 0%, P = 0.047). There was no significant difference in any of the descriptive study characteristics (age, gender, diabetes and presence of neuropathy). The results of this initial study suggest that chlorhexidine gluconate-impregnated polyurethane dressing may be effective to reduce the incidence of pin tract infections and help decrease morbidity associated with external fixation.
