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：Background The efficacy of pulsed dye laser combined (PDL) and UltraPulse fractional CO2 in treatment of hypertrophic scars is well documented. The present study investigates the efficacy of moist exposed burn ointment (MEBO)/moist exposed burn therapy (MEBT) in postlaser wound management. Methods Sixty-one patients with immature, red hypertrophic scars were enrolled in this clinical trial. Patients were randomly divided into two groups: (a) the MEBO treatment group (n = 30) and (b) the control group (n = 31) treated with chlortetracycline hydrochloride ointment. Demographic data such as age, gender, and cause of scars were recorded. A visual analogue score (VAS) was collected to measure pain at 1, 6, 24, 72 hours, and 7 days post-treatment. The Vancouver Scar Scale (VSS) was used to determine the response of the scars before and 3 months after the treatment. The wound healing time and pigmentation scores were also recorded. Results No significant differences were found in age, gender, and etiology of the scars in the two groups. The VAS scores in MEBO group were significantly lower than the control group within the first 3 days after treatment. The wound healing time of the MEBO group was significantly shorter than the control group. For both groups, VSS scores were significantly decreased and the scar markedly improved. However, the VSS scores were significantly lower in the MEBO group compared with the control group 3 months after treatment and pigmentation formation was dramatically lower in MEBO group compared with the control. Conclusion MEBT/MEBO treatment reduced the post-treatment pain, shortened the wound healing duration, promoted the overall scar condition, and reduced the incidence of pigmentation.

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.
