Abstract:
BACKGROUND:Negative pressure wound therapy has been widely recognized, the currently published papers are limited in academic value and lack of scientific, objective, qualified index to confirm the therapy effectiveness. OBJECTIVE:To systemical y evaluate the clinical effect of negative pressure wound therapy, provide more evidence for its clinical application, and guide clinical research.
METHODS:Fifteen articles were screened out of peer-reviewed publications (Cochran library, Embase, PubMed-Medline and Chinese BioMedical Literature Database). Scientific data were col ected and evaluated by two researchers. The data were statistical y analyzed with RevMan software.
RESULTS AND CONCLUSION:Only 15 random-control ed trials were final y preserved, including 10 as B-grade moderate bias risk and focused on the effect of negative pressure wound therapy on chronic wounds, and 5 as C-grade high bias risk and focused on the effect of negative pressure wound therapy on acute wounds. There were significant differences in the main outcome measures between negative pressure wound therapy and conventional wound therapy. As for chronic wound patients, no significant difference was observed in the operation-preparing period, reducing wound area, promoting wound granulation, and amputation rate between two therapies. As for acute wound patients, the differences were significant in the operation-preparing period, promoting wound granulation, wound infection rate, and cost materials between two therapies. However, no difference was significant in the healing of wound and hospitalization time. Our findings indicate that, negative pressure wound therapy is an effective means for both acute and chronic wounds, it can shorten operation-preparing period, promote wound granulation, and reduce amputation rate and infection rate, thus providing evidence for clinical application. The wel-designed study is needed to develop high-quality random control ed trails.
