Two different methods for contacting fluid with the dressings were used, to simulate wounds with different levels of exudate: i) immersing the dressing in 35ml fluid, and ii) adding 5ml drop-wise onto the dressing's absorbent pad on a daily basis. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> on immersion of the dressings, the pH values of the fluids changed quite appreciably over time, with similar results for both methods. The lowest pH values were found with the hydrocolloid dressings, for both solution a and distilled water. The foam dressings had an alkaline effect on the fluids; in most cases, they increased the fuid's pH significantly. The non-woven dressings reduced the pH of both fluids to a lesser extent than the hydrocolloid dressings. The hydroactive dressings decreased the pH value of solution a and increased the pH of distilled water. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p> This study demonstrates that the pH values of the fluids are not constant, likely due to the complicated nature of the dressings\u2019 chemical structures and designs. Thus, optimisation of pH level to meet the requirements of any specific wound types and healing processes must consider the complex nature of the dressing. The increase in pH value of the wound over time needs to be minimised in order to maximise the effectiveness of the healing therapy. <\/jats:p><\/jats:sec><jats:sec><jats:title>Declaration of interest:<\/jats:title><jats:p> This work was supported by a financial grant from the Turkish Council of Higher education in collaboration with Marmara university, Turkey and the university of Bolton, UK.
