Abstract:

[Abstract] Objective To evaluate the clinical effects of platelet-rich plasma in treatment of Deep Ⅱ burn wounds. Methods Sixty eight cases of inpatients with Deep Ⅱ burns were selected, whose age were from 1 to 65 years and their burn areas were between 5%～ 62% of total body surface area (TBSA). Deep gradeⅡ burn of each sample was divided into two parts. Part A was the treatment group and part B was the control group． The burn wounds in the treatment group were treated with platelet-rich plasma and the counterpart in the control group were treated with SD-Ag. Healing time， recovering rate and the frequency of dressing changes， frequency of changing the most innerlayer gauze and the rate of wound infection were also analyzed. Finally the laboratory abnormalities and adverse effect were monitored regularly. Results The healing time of the treatment group (16.5±3.1 ) d was shorter than that of the control group (19.5±3.8 ) d. The recovering rate of the treatment group was higher than that of the control group on the 14th and 17th day after treatment. There were statistically sig? nificant differences between these two groups (P＜ 0.05). After two weeks’ treatment, the internal and external dressing per? meability into wet gauze layers were 20.6±1.7, which were significantly decreased than that in the control group 23.3±5.9. The frequency of dressing changes was（7.2±1.1） times in treatment group versus（9.2±1.4） times in control group and the frequency of changing the inner most layer gauze was（ 2.3±0.6） times in the treatment group versus（5.3±1.3） times in con? trol group. There were 5 inflammation reaction cases in the treatment group, but 13 cases in the control group. However， there was no statistic significance between the two group in the outcomes of bacterial culture, the laboratory abnormalities and the adverse effect. Conclusion Platelet-rich plasma can remarkably shorten the healing time， improve healing rate， re? duce frequency of dressing change and promote wound healing for deep Ⅱ burn wound. PRP is a potential safety reagent in treating deep Ⅱ burn wound．
