[摘 要]目的 探讨在浅表性瘢痕患者中应用点阵CO2激光联合重组Ⅲ型胶原蛋白冻干纤维的效果。方法 选取石家庄市妇幼保健院/石家庄市儿童医院2024年1月-5月收治的50例浅表性瘢痕患者为研究对象，采用随机数字表法分为对照组和观察组，各25例。对照组给予点阵CO2激光治疗，观察组给予点阵CO2激光联合重组Ⅲ型胶原蛋白冻干纤维治疗，比较两组临床相关指标、临床疗效、瘢痕情况及不良反应发生情况。结果 观察组水肿时间、红斑持续时间、刺痛时间、愈合时间均短于对照组(P<0.05)；观察组治疗总有效率为96.00%，高于对照组的68.00%(P<0.05)；两组治疗后瘢痕色泽、厚度、血管分布、柔软度评分低于治疗前，且观察组低于对照组(P<0.05)；观察组不良反应发生率为0，低于对照组的16.00%(P<0.05)。结论 点阵CO2激光联合重组Ⅲ型胶原蛋白冻干纤维在浅表性瘢痕患者中的应用效果确切，可加快患者皮肤组织恢复速度，改善瘢痕情况，且治疗后不良反应发生几率较低，应用安全性良好。

    [Abstract]Objective To investigate the effect of CO2 fractional laser combined with recombinant type Ⅲ collagen freeze-dried fiber in patients with superficial scar. Methods A total of 50 patients with superficial scar admitted to the Shijiazhuang Maternal and Child Health Hospital/Shijiazhuang Children’s Hospital from January to May 2024 were selected as the research objects. They were divided into control group and observation group by random number table method ......
