摘要：目的:探究湿性医疗技术在PDL联合CO2点阵激光治疗早期红色瘢痕术后创面修复中的应用效果。方法:选取笔者科室2018年1月-2019年10月收治的120例早期红色瘢痕患者为研究对象,根据数字随机表法分为对照组和观察组,每组60例。对照组采用PDL联合CO2点阵激光治疗,观察组在此基础上实施湿润烧伤膏进行创面护理,比较两组患者愈合效果、创面愈合时间、数字疼痛分级法（NRS）评分、温哥华瘢痕量表（VSS）评分及并发症发生率。结果:观察组总有效率为95.00%,高于对照组的83.33%（P<0.05）;观察组护理干预后,创面愈合时间、NRS评分以及VSS评分均少于或低于对照组（P<0.05）;观察组并发症发生率为6.67%,低于对照组的20.00%（P<0.05）。结论:PDL联合CO2点阵激光治疗早期红色瘢痕术后创面修复,采用湿性医疗技术效果明显,可促进创面愈合速度,减轻创面疼痛,安全性高,值得临床推广及应用。

摘要：Introduction The objective of this study was to investigate the clinical effects of laser therapy in treating cicatricial ectropion. Methods Seven patients with cicatricial ectropion were entered into this clinical study. The ectropions were pretreated with the 595-nm pulsed dye laser if the scar color was red. If there was no red, the UltraPulse fractional CO2 laser was used and parameters were adapted according to the height of scar. MEBT/MEBO was used after laser treatment for wound healing. The degree of ectropion was measured for changes before and after treatment, and the scars were evaluated for changes in melanin, height, vascularity, and pliability using the Vancouver Scar Scale (VSS) before and after treatment. Results All seven patients with cicatricial ectropion entered into this protocol were completely corrected after 1-2 treatment sessions. The total VSS score, as well as the score for melanin and pliability in 7 patients, showed a decrease following the treatments, and this was statistically significant (P < 0.05). The scores for height and vascularity showed a decrease following the treatments, but there was no significant difference by statistical analysis (P ≥ 0.05). There were no adverse reactions reported. Conclusions The treatment of cicatricial ectropion with laser therapy can not only correct the ectropion, but also improve the scars in the treatment area. Compared with the traditional repair of cicatricial ectropion, the use of fractional CO2 laser provides surgical precision and the advantage of a timely treatment without the need to wait for the scar to stabilize.

摘要：Introduction The objective was to investigate the clinical effect of an adjustable pulse width Pulsed Dye Laser (PDL) vs an adjustable pulse width PDL combined with fractional CO2 laser in treating immature red hypertrophic scars. Methods Fifty-six patients (56 sites)were randomly divided into a treatment group and control group. The control group was treated with the 595 nm PDL at a fluence of 7-15J/cm2 and pulse widths of 1.5-3 ms, 7 mm spot size. The treatment group was treated with a fractional CO2 laser (UltraPulse CO2: Deep FX, Energy: 30 50 mJ, Frequency: 300 Hz, Density 5%, Scan Shape, and Spot Size were decided by shape and area of scar) after utilizing the 595 nm adjustable pulse width PDL (Fluence: 7-15J/cm2, Pulse widths: 1.5-3 ms, Spot size: 7 mm). MEBT/MEBO, previously described as a post-treatment wound ointment, was used after laser treatment. The scars of the treatment group and the control group were evaluated for changes in pigment, height, vascularity, and pliability using the Vancouver Scar Scale (VSS) after two laser treatments. Results The total VSS score, as well as the score for melanin, height, vascularity, pliability in both groups, showed an obvious decrease following the treatments. There were statistically significant differences between before treatment and after treatment (P < .05); however, the total score of the VSS, and score of the melanin, height, vascularity, and pliability in the control group decreased more than that of treatment group, and there was a statistically significant difference (P < .05). Conclusions The 595 nm adjustable pulse width PDL combined with the fractional CO2 fractional laser appears to have a beneficial clinical effect on fresh red hypertrophic scars, with no severe adverse reactions seen.
