title: Clinical Evaluation of a Novel Topical Negative Pressure Device in Promoting Healing in Chronic Wounds.
abstract: Aim:This observational study evaluated the use of a novel, ultraportable, mechanically powered topical negative pressure device in promoting healing in chronic wounds, including venous and mixed etiology leg ulcers and neuropathic foot ulcers.Materials and Methods:Evaluable patients (n=37) received treatment with the SNaP®Wound Care System for up to 6 weeks. The primary objective was percentage change in wound size, with secondary objectives of clinical assessment of wound parameters, ease of use, and impact on quality of life.Results:A 42.64% mean percentage decrease in wound area was observed, with an overall decrease for each wound etiology subgroup. Increased granulation tissue, decreased exudate levels, and decreased wound pain were reported. Quality-of-life scores increased overall, and the device was easy to use, comfortable, portable, and inconspicuous.Conclusion:The SNaP Wound Care System has the potential to promote healing in chronic wounds of different etiologies.
