低强度激光对比负压封闭引流治疗软组织创面的疗效观察

目的 观察低强度激光对比负压封闭引流（VSD）治疗创面的疗效。 方法 选取48例皮肤软组织创面病人，随机分为激光组（n=24）及VSD组（n=24）。激光组给予外科换药+低强度激光治疗；VSD组给予VSD治疗，观察比较2组治疗7 d及14 d的创面愈合情况、创面肉芽成熟程度、住院时间、疼痛程度、治疗疗效及病人满意程度。 结果 治疗7 d及14 d 2组间创面愈合情况差异无统计学意义（P>0.05）；2组治疗后创面肉芽组织成熟度差异无统计学意义（P>0.05）。激光组较VSD组住院时间、治疗7 d及14 d疼痛程度均降低（P < 0.05）。2组病人满意度及治疗疗效差异均有统计学意义（P < 0.05）。 结论 采用低强度激光治疗创面，可以加速创面愈合，较VSD便于操作，易被病人接受，明显减轻病人疼痛，值得临床推广，综合治疗创面。

Effect comparison between low-level laser and vacuum sealing drainage in the treatment of wound surface

Objective To compare the effects between low-level laser and vacuum sealing drainage(VSD) in the treatment of wound surface. Methods Forty-eight patients with skin soft wound were randomly divided into the laser group(n=24) and VSD group(n=24).The laser group was treated with surgical dressing combined with low-level laser, and the VSD group was treated with VSD.The wound healing, granulation tissue maturity, average hospitalization time, pain degree, therapeutic effect and satisfaction between two groups after 7d and 14d of treatment were compared. Results The differences of the wound healing between two groups after 7 d and 14d of treatment were not statistically significant(P>0.05), and the difference of the granulation tissue maturity between two groups after treatment was not statistically significant(P>0.05).Compared with the VSD group, the average hospitalization time and post-treatment pain in laser group decreased(P < 0.05).The differences of the satisfaction and therapeutic effects bewteen two gorups were statistically significant(P < 0.05). Conclusions The low-level laser in the treatment of wound suurface is simple and can easily be accepted by patients, which can accelerate the healing of the wound, and significantly reduce the pain of patients.It is worthy of clinical promotion.
