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 Ò 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.

The smart negative pressure (SNaP) wound care system: A case series from Singapore

“…A substantial 15 patients experienced wound infection and underwent treatment suspension until the infection resolved. However, 46% of patients reported an improvement in the overall quality of life, and indicated that the SNaP system was user‐friendly and less burdensome than conventional NPWT …”

“…Nevertheless, the overall quality of the current evidence remains poor, comprising of sporadic case series, retrospective studies, and only two RCTs with inconsistent conclusions. Whilst no firm conclusion can be made regarding its superiority over current NPWT systems in terms of wound‐healing outcomes, there are clear benefits from the shorter device application time, improved patient satisfaction, and quality of life …”

“…These encouraging results have prompted the initiation of clinical studies examining this comparison. Preliminary data have now emerged from both randomised controlled trials (RCTs) and retrospective studies, albeit with mixed conclusions, and predominantly from Western populations. Singapore General Hospital is the first hospital in Singapore to have gained access to this device.…”

Instrumentos para avaliação da cicatrização de lesões de pele: revisão integrativa

“…Ainda, seis (17,1%) estudos eram de coorte (29)(30)(31)(32)(33)(34) , três (8,6%) observacionais longitudinais (35)(36)(37) , e um (2,9%) caso-controle (38) . Os outros 11 (31,4%) eram estudos com abordagem descritiva (5,7,(39)(40)(41)(42)(43)(44)(45)(46)(47) Dentre os estudos que compuseram esta revisão, 26 (74,3%) utilizaram diferentes instrumentos validados para a avaliação do processo de cicatrização de lesões de pele, sendo que em três (8,6%) estudos, foram utilizados mais de um instrumento. Os demais estudos (25,7%) utilizaram a observação e a mensuração de variáveis clínicas para a avaliação das lesões e de características complementares das lesões.…”
