水胶体敷料治疗超脉冲CO_2激光术后创面的疗效观察

Therapeutic effect of hydrocolloid dressing after laser resurfacing

目的:观察水胶体敷料对激光术后创面愈合的促进作用。方法:将22例经超脉冲CO_2激光治疗术后患者的44个创面随机分治疗组和对照组。治疗组于术后第1天开始外用水胶体敷料,隔日换敷料,1周后为隔周换药至第6周结束;对照组于术后每日涂擦金霉素眼膏,1周后停用。每次复诊时观察红斑、色素沉着及创面情况并留取资料。在术后第8周复诊观察最终疗效。结果:治疗组和对照组的平均愈合时间分别为(6.71±0.86)d和(8.18±0.88)d,平均红斑持续时间分别为(8.71±0.99)d和(19.06±2.25d)d,色素沉着发生率分别为11.2%和18.9%,差异均具有统计学意义。结论:水胶体敷料可明显促进超脉冲CO_2激光术后创面的愈合,且可显著增加患者对创面愈合的满意度。

Objective： To evaluate a new hydrocolloid dressing for promoting wound healing after laser skin resurfacing （LSR）. Methods： Twenty two patients with pigmented nevi with 44 wounds on the face and neck after carbon dioxide laser treatment were divided into two groups： the treatment group received the dressing every other day for 7 days, and then every week after LSR for 6 weeks; the control group was treated with traditional dry method. All patients were evaluated and pho- tographed every return visit. The degrees of erythema, pigmentary changes, and the healing condition of the wounds were documented,and the final therapeutic result was compared 8 weeks after treatment. Results： The hydrocolloid dressing group had a shorter healing time （6.71±0.86 VS 8.18±0.88）d, and the average persisting time of erythema （8.71±0.99 VS 19.06± 2.25）d. The incidence of post inflammatory pigmentation of treatment group was also lower than that of the control group （11.2 %VS 18.9%, P〈 0.05）. Patients used hydrocolloid dressing treatment was more satisfied with therapeutic effect than that of the control group. Conclusion： Hydrocolloid dressing has conspicuous effect in promoting wound healing after carbon diox- ide laser treatment.
