Abstract

Abstract: BACKGROUND: At present, platelet-rich plasma has been used in burns, plastic surgery, surgery and orthopedics. However, due to the different standards for platelet-rich plasma preparation, the results of research on burns are controversial.
OBJECTIVE: To systematically evaluate the effectiveness of platelet-rich plasma in the repair of burn wounds.
METHODS: A computer-based online search of CNKI, VIP, WanFang, CBMdisc, PubMed, Embase, Cochrane Library, Web of Science databases to retrieve randomized controlled trials regarding platelet-rich plasma repair of burn wounds. In the treatment group, platelet-rich plasma therapy or platelet-rich plasma therapy combined with conventional or other therapies were used. In the control group, conventional therapy, other therapies, or placebo treatment were used. After literature screening, information extraction and quality evaluation, Review Manager 5.3 software was used for meta analysis.
RESULTS AND CONCLUSION: Eleven articles were included, involving 837 patients consisting of 420 patients in the treatment group and 417 patients in the control group. Meta analysis results revealed that the wound healing rate in the treatment group was significantly higher than that in the control group [OR=12.61, 95%CI (6.93, 18.29), P < 0.000 1]. Wound healing time in the treatment group was significantly shorter than that in the control group [OR=-4.64, 95%CI (-6.21, -3.06), P < 0.000 01]. The number of layers of gauze soaked by dressing [OR=-4.01, 95%CI (-4.91, -3.11), P < 0.000 01], the times of changing inner gauze [OR=-3.79, 95%CI (-5.33, -2.26), P < 0.000 01, and the times of dressing change on wound surface [OR=-3.41, 95%CI (-5.93, -0.88), P=0.008] in the treatment group were significantly less than those in the control group. The positive rate of bacterial culture in wound [OR=0.46, 95%CI (0.22, 0.94), P=0.03] and the incidence of inflammatory reaction in wound [OR=0.30, 95%CI (0.17, 0.56), P=0.000 1] in the treatment group were significantly lower than those in the control group. The results suggested that platelet-rich plasma can increase the wound healing rate, shorten wound healing time, reduce the number of layers of gauze soaked by dressing, the times of changing inner gauze, and the times of dressing change on wound surface, and lower the positive rate of bacterial culture and the incidence of inflammatory reaction in wound.
