简要总结
To compare the effect of a class I pullulan based medical device containing Allium cepa & HA versus a class I medical device silicone gel on new post-surgical wounds
详细描述
A head-to-head, randomised, pivotal controlled trial evaluating the appearance of post-surgical scars for 12 weeks. The study was developed in 10 months, including recruitment, evaluation every 4 weeks and evaluation of the secondary objective in the third month (T2). The primary endpoint was the evaluation of the effectiveness of the class I medical device contain onion (Allium cepa) extract compared to the silicone gel used in the treatment of post-surgical scars for the prevention of hypertrophic scars. Objective scar assessment using the Vancouver Scar Scale (VSS), Manchester Scale, Patient and Observer Scar Assessment Scale (POSAS), itching, redness and pliability were performed after 4,8 and 12 weeks of treatment. Safety was also evaluated by gathering adverse events related to application of the gel. The statistical analysis of the data was carried out by applying parametric or non-parametric tests depending on the distribution of the data that was going to be obtained. The one-way analysis of variance ANOVA test was used to evaluate the reduction/increase of clinical parameters in the pre-established observation times (T0, T2, T3 and T4) for each treatment, whereas comparison between treatments was performed via t-test analysis. Correlation tests were also used. The differences were considered statistically significant for p values <0.05.

结局指标
主要结局
Change of pliability from baseline to weeks 4,8 and 12
时间窗: week 4,8,12
Change of pliability from baseline to weeks 4,8 and 12 will be measured by testing folding of the scar with a six-step scale: normal, supple, yielding, firm, banding, and contracture. Lower score denotes a better outcome (range: 0-10).
Change of redness from baseline to weeks 4,8 and 12
时间窗: week 4,8,12
Change of redness from baseline to weeks 4,8 and 12 will be evaluted as 10 points scale, from normal (1 point) to purple (10 points). Lower score denotes a better outcome (range: 0-10).
Change of Vancouver Scar Scale (VSS)
时间窗: week 4,8,12
Change of Vancouver Scar Scale (VSS) from baseline to weeks 4,8 and 12. * vascularity(range from normal(0 point) to purple(3point) * pigmentation(range from normal(0 point) to hyper-pigmentation(3point) * pliability(range from normal(0 point) to contracture(5point) * height (range from flat(0 point) to above 5mm(3point) * pain(range from none(0 point) to Require medication(2point) * itchiness(range from none(0 point) to Require medication(2point) We assess total score that are minimum score is 0 and maximum is 18. The lowest score means the best scar condition.
Change of Manchester Scale
时间窗: week 4,8,12
Change of Manchester Scale from baseline to weeks 4,8 and 12. * Color (range from perfect (1 point) to Gross mismatch (4 points) * Shine ( from matte (1 point) to shiny (2 points)) * Contour ( from Flush with surrounding skin (1 point) to keloid (4 points)) * Distortion ( from none (1 point) to severe (4 points)) Lower score denotes a better outcome using the MSS (range: 4-14).
Change of Patient and Observer Scar Assessment Scale (POSAS) from baseline to weeks 4,8 and 12.
时间窗: week 4,8,12
Change of Patient and Observer Scar Assessment Scale (POSAS) from baseline to weeks 4,8 and 12. Lower score denotes a better outcome using the POSAS (range: 0-10).
Change of itching from baseline to weeks 4,8 and 12
时间窗: week 4,8,12
Change of itching from baseline to weeks 4,8 and 12 will be measure with the visual analogue scale (VAS). Lower score denotes a better outcome using the VAS (range: 0-10).
次要结局
- Incidence of adverse events occurrence after treatment(week 12)
