Nano-Silver Medical Antibacterial Dressing Combined with High-Flow Oxygen Therapy Facilitates Ulcer Wound Healing of Superficial Malignant Tumors.

Abstract

BackgroundDue to the poor healing of superficial malignant tumor ulcer wounds, patients suffer great pain and significantly reduced quality of life. Related research shows that oxygen therapy can reduce wound bleeding and promote wound healing.ObjectiveThis study aims to explore the therapeutic effect of nano-silver antibacterial dressing combined with high-flow oxygen therapy on surface malignant tumor ulcers.MethodsIn this retrospective analysis, 64 patients with superficial malignant tumors and ulcer infection were included and divided into the research group and the control group, with 32 cases in each group. After conventional debridement, the control group was treated with vaseline dressing, while the research group was treated with nano-silver medical antibacterial dressing combined with high-flow oxygen therapy. Both groups were treated for 7 days. The frequency of dressing change and the number of times of blood oozing between the two groups after treatment were recorded. The pain, clinical efficacy, and levels of procalcitonin (PCT) and C-reactive protein (CRP) were compared between the two groups before and after treatment.ResultsThe dressing changes and blood oozing were less frequent in the research group compared with the control group. The pain score and the levels of PCT and CRP in the research group were lower than those in the control group. The overall response rate was significantly higher in the research group as compared to the control group. All the above differences were statistically significant (P<0.05).ConclusionNano-silver medical antibacterial dressing combined with high-flow oxygen therapy can reduce the frequency of dressing changes in patients, relieve pain, reduce inflammation, and accelerate the healing of superficial malignant tumor ulcer wounds.
