Abstract:
Objective To explore the effects of vacuum sealing combined with NovaBay on improving diabetic foot wound healing, and to offer new insights and methods for treating chronic aporetic wounds. Methods Totally 130 patients with diabetic foot ulcer admitted in the Second Affiliated Hospital of Zhejiang Chinese Medical University between November 2015 and November 2016 were randomly and equally divided into two groups. Patients in the treatment group received 5 ml NovaBay for twice a day on the basis of vacuum sealing drainage (VSD), and received drainage 5 min after treatment with NovaBay, while patients in the control group received vacuum sealing drainage with 5 ml 0.9% sodium chloride solution for twice a day, and received drainage 5 min after treatment of sodium chloride solution. The intervention time of the patients in both groups were 12 days, with NovaBay and ducts replaced every 3 days. The patients in the two groups were evaluated with Pressure Ulcer Scale for Healing (PUSH) and the coverage rate of granulation tissue was calculated 0, 6, and 12 days after the intervention. And the positive rate of bacteria was tested at the end of the intervention. Results The PUSH scores of the patients in the two groups decreased as time went by, indicating that the wound healing was effective (P<0.001). The coverage rate of granulation tissue rose with time, and that of the patients in the treatment group rose more obviously (P<0.001). 12 days after the intervention, the patients in the treatment group (4.62%) showed a lower positive rate of bacteria (P<0.001) than the patients in the control group (47.70%). Conclusions Vacuum sealing combined with NovaBay shows remarkable effects in cleaning infection of chronic and aporetic wounds, thus a new and effective way to improve the growth of granulation tissue and wound healing.
