The Effect Of Self-adhesive Silicone Dressings Combined With Pressure Therapy To Inhibit Scar Formation After Surgery

Objectiv e:Compare the effect of inhibiting the surgical incision scars between the self-adhesive silicone dressing combined with pressure therapy and the simple pressure therapy, and provide a basis to select the better way to suppress scar after surgery.Methods:This was a randomized controlled trial, and selected60patients randomly from March2010to March2012in Hunan Provincial Tumor Hospital stoma wound center for treatment after surgery incision scars time less than2years, with a random number table patients divided into experimental group (78patients) and control group (70patients). The experimental group was treated with a self-adhesive silicone dressings combined with pressure therapy, while the control group was treated with pressure therapy. Evaluate the treatment scores of scar itching, tingling, hardness, color, thickness variation reference to the Vancouver scar criteria of both groups before and after, and judged the results markedly effective, ineffective, effective and total efficiency reference to Zhang Ling scar determine the efficacy of criteria.Results:1. Three-month review of the case:78scar of the experimental group,10markedly effective (12.8%),9effective (23.1%),22(28.2%) invalid; the70scar of the control group,2markedly effective (2.9%),22effective (31.4%), and46(65.7%) invalid.2. Six-months, when the review:78scar of the experimental group,22markedly effective (28.3%),30effective (38.5%),8(10.3%) invalid; the70scar control group,16markedly effective (23.5%),20effective (29.4%),28(40.0%) invalid.3. Compared the efficacy of three months and six months of the experimental group and the control group by the two independent sample nonparametric rank sum test, of ordinal variables,The difference was statistically significant(P<0.05). 4. After compared the effect of the experimental group with the control group of the scar itching, tingling, hardness, color, thickness by the use of repeated measurement data analysis of variance, the effect of the itching, tingling aspects of the experimental group was better than the control group. The difference was statistically significant (P<0.05).5. The treatment of the six months was better the than three months by using the analysis of variance, the difference was statistically significant (P<0.05).Conclusion:1. Self-adhesive silicone dressings combined with pressure therapy is an effective method for the treatment of surgical incision scars, and this therapy can effectively improve the symptoms, color and appearance of the scar.2. Self-adhesive silicone dreessings combined with pressure therapy is particularly effectively improving the scar itching symptoms after surgery.3. The six months treatment of scar is better than three months treatment.
