Abstract:
Objective To investigate the effect of platelet-rich plasma (PRP) combined with negative pressure wound therapy (NPWT) on orthopedic refractory wound.Methods A total of 84 patients with chronic refractory wound were selected from January 2014 to December 2016 in Department of Osteology,Jizhong Energy Xingtai Mining Group General Hospital.The patients were divided into control group and observation group according to the admission time,42 cases in each group.The patients in the control group were treated with NPWT,and the patients in the observation group were treated with PRP and NPWT.The power of hydrogen (pH) of wound exudate,wound temperature and wound pressure ulcer scale for healing (PUSH) were compared between the two groups before and after treatment.The bacterial cuhure result was compared between the two groups after two weeks of treatment.The change of serum erythropoietin (EPO) level were observed before and four weeks after treatment,and the suitable skingrafting time,wound healing time and cure rate were observed in the two groups.Results After two weeks of treatment,the positive rate of bacterial culture in the observation group was significantly lower than that in the control group (x2 =4.850,P ＜ 0.05).The pH value of wound exudate and the wound PUSH score in the observation group were significantly lower than those in the control group(P ＜0.05),but the wound temperature in the observation group was higher than that in the control group after two weeks of treatment (P ＜ 0.05).The results of intra group comparison showed that the serum EPO level showed an upward trend within four weeks of treatment,and the difference was statistically significant at different time points in the two groups (F =7.356,8.264;P ＜ 0.05).The level of serum EPO in the observation group was significantly higher than that in the control group at the treatment of 1,2,3 and 4 weeks (P ＜ 0.05).Compared with the control group,the suitable skingrafting time was early (P ＜ 0.05),the wound healing was fast (P ＜ 0.05),and the cure rate was high in the observation group (x2 =4.720,P ＜ 0.05).Conclusion The combination of PRP and NPWT has good antibacterial effect,and can promote the EPO level and wound healing.
