Abstract:[Objective] To evaluate the efficacy of antibiotic-loaded bone cement (ABC) combined with low-dose dexamethasone palmi- tate (DXP) for diabetic foot ulcer (DFU) . [Methods] From November 2020 to May 2022, 36 patients with DFU were randomly divided into the DXP group and the saline group. After debridement and ABC application, the DXP group was injected low-dose DXP locally at 3, 6 and 9 days, while the saline group received normal saline injection locally. The clinical data were compared between the two groups. [Results] The DXP group proved significantly superior to the saline group in terms of hospital stay, wound healing time and wound healing rate (P< 0.05) . The VAS for pain significantly decreased over time in both groups (P<0.05) , which in the DXP group was significantly better than the saline group at 9 and 15 days after treatment (P<0.05) . With regard to laboratory test, the positive rate of wound bacterial culture decreased significantly in both groups over time (P<0.05) , without a significant difference in the positive rate between the two groups at any correspond- ing time points (P>0.05) . Compared with those before treatment, the TNF-α and IL-6 significantly decreased in both groups 15 days after treatment (P<0.05) , which in the DXP group proved significantly lower than the saline group at 15 days after treatment (P<0.05) . [Conclusion] ABC combined with low-dose DXP does effectively promote wound healing for diabetic foot ulcer.
