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.
