Objective To observe the therapeutic effect of ultrasound debridement and traditional Chinese medicine foot bath in Wagner grade 2 or grade 3 ulcer of diabetic foot.

Methods A total of 60 patients with Wagner grade 2 or grade 3 ulser in diabetic foot were selected and randomly divided into observation group (30 patients) and control group(30 patients). The observation group was treated with ultrasonic debridement combined with traditional Chinese medicine foot bath, and the control group was treated with mechanical surgical debridement. Four weeks later, the wound healing and the changes of hypersensitive C reactive protein and procalcitonin levels of the two groups were recorded, and the overall treatment effect was observed.

Results After 4 weeks of treatment, the wound area of the observation group was (1.86±0.61) cm², and the wound reduction rate was (86.13±12.36)%, while the wound area of the control group was (4.53±0.87) cm², and the wound reduction rate was (52.28±14.57)%. The wound area of the observation group was smaller than that of the control group, and the wound reduction rate was higher than that of the control group (P < 0.05). After treatment, high sensitivity C-reactive protein and procalcitonin in the observation group were (6.42±1.82) mg/L and (0.21±0.16) ng/L, respectively, which were lower than (12.38±2.46) mg/L and (0.35±0.32) ng/L in the control group (P < 0.05). The total effective rate of treatment in the observation group was 83.33%, which was higher than 56.67% of the control group, and the difference was statistically significant (P < 0.05).

Conclusion Treatment of ultrasonic debridement and Chinese medicine foot bath can promote granulation tissue growth, wound healing and improve blood circulation of affected limb, which is worth of clinical promotion and application.
