Clinical Study of 460 nm Blue Light and 640 nm Red Light Combined Irradiation on Promoting Wound Healing of Stage 3 and 4 Pressure Ulcers
460nm蓝光和640nm红光联合照射促进3期、4期压疮创面愈合的临床研究

摘要

目的：探讨460nm蓝光和640nm红光联合照射促进3期、4期压疮创面愈合的临床疗效。方法选取2019年7月至2021年1月于我院进行治疗的压疮患者40例为研究对象，根据入院时间编号顺序将40例患者分为对照组(n=20)和实验组(n=20)，对照组患者只给予基础治疗，实验组患者在基础治疗后接受460nm蓝光和640nm红光联合照射治疗，比较两组患者治疗效果。结果 与对照组比较，实验组患者创面愈合率、时间点VAS评分、完全愈合时间和Bates-Jensen伤口评分明显优于对照组(P<0.05)。结论 采用460nm蓝光和640nm红光联合照射治疗3期、4期压疮效果较好，值得临床推广。

Abstract

Objective:To investigate the clinical effect of combined irradiation of 460nm blue light and 640nm red light on wound healing of pressure sore in stage 3 and stage 4.
Methods:40 patients with pressure sore treated in our hospital from July 2019 to March 2021 were selected.According to the sequence of admission time,40 patients were divided into control group(n=20) and experimental group(n=20).The patients in the control group were only given basic treatment,and the patients in the experimental group were treated with 460nm blue light and 640nm red light after basic treatment.the therapeutic effects of the two groups were compared.
Results:Compared with the control group,the wound healing rate,VAS score,complete healing time and Bates-Jensen wound score in the experimental group were significantly better than those in the control group.
Conclusion  ：The combination of 460nm blue light and 640nm red light is effective in the treatment of stage 3 and stage 4 pressure ulcers,which is worthy of clinical promotion.
