Polyvinyl alcohol hydration algae salt bubble wound dressings with sealing negative pressure drainage repair diabetic foot ulcers / 中国组织工程研究

ABSTRACT

BACKGROUND:Biological dressings with sealing negative pressure drainage can promote the healing of acute and chronic wounds. OBJECTIVE:To observe the clinical effects of biological dressings with sealing negative pressure drainage in repair of diabetic foot ulcer. METHODS: Totaly 40 patients with diabetic foot ulcer were enroled and al underwent debridement or debridement plus skin grafting treatment. Wound treatment methods were selected according to the wiling of patients. Patients in the test group (n=20) underwent polyvinyl alcohol hydration algae salt bubble wound dressings with sealing negative pressure drainage. Patients in the control group (n=20) underwent regular wound dressing treatment. At the 7th RESULTS AND CONCLUSION: The visual analog scale scores, blood sedimentation, C-reactive protein levels in the test group were lower than those in the control group (P < 0.05). The wound healing time in the test group was shorter than that in the control group (P < 0.05), and the patient satisfaction was higher in the test group than the control group (P < 0.05). There was no significant difference in economic costs between the two groups. There was no local or systemic toxicity, alergy and other adverse reactions in the test group. These results day of repair, visual analog scale scores, blood sedimentation, C-reactive protein levels, wound healing time, patient satisfaction and economic costs at the termination of the treatment in these two groups were compared. demonstrate that polyvinyl alcohol hydration algae salt bubble wound dressings with sealing negative pressure drainage in repair of diabetic foot ulcer is safe and effective to promote wound healing and reduce local inflammatory response.
