    Abstract:
    Few studies have investigated the use of dressings on patients with diabetic foot ulceration. This paper reports the results of a non-comparative, two-centre study investigating the performance characteristics of SeaSorb dressing in patients with this condition. This was an exploratory study to determine the potential use of this dressing, and not a large randomised control trial. All patients had diabetic foot ulceration of 1 cm or more in diameter, classified as Wagner grade I or II, with an ankle brachial pressure index of > 0.4. The investigators carried out objective assessments including photography and ulcer tracing as well as subjective assessments of exudate levels, wound bed condition, peri-ulcer skin condition, ease of application and removal of the dressing, dressing conformability, discomfort during dressing application and removal, and clinical signs of infection. Investigators recruited 41 patients in two sites (31 in site one and 10 in site two). Of these, the findings relating to 39 patients could be evaluated. The patients were treated for a maximum of six weeks or until the ulcer healed. The study found that 28.2% (11/39) of the ulcers healed within the six-week period. Overall, there was a significant reduction in mean ulcer area from 2.8 cm 2 to 1.02 cm 2 from week 0 to week six. The relative ulcer area showed a significant decrease from 100% to 33%. For patients who experienced ulcer pain (11 patients), its intensity decreased over the six weeks. Severe maceration was not reported for any patient throughout the study. Six patients required treatment for infection. A total of 12 adverse events were reported: seven mild to moderate and five severe. None were directly attributed to the study dressing.
