【摘要】 目的 觀察富血小板血浆(PRP)治疗糖尿病足难愈性创面的临床疗效。方法 38例糖尿病足患者, 根据治疗方法不同分为实验组(22例)和对照组(16例)。对照组采用常规方法治疗, 实验组在对照组基础上联合PRP治疗。比较两组治疗后1、2、3周的创面愈合率、愈合时间、截肢(趾)率及创面复发率。结果 治疗后1、2、3周, 实验组创面愈合率分别为(26.6±5.5)%、(58.4±8.4)%和(93.6±9.2)%, 对照组分别为(21.8±5.7)%、(38.7±6.8)%和(62.5±9.3)%。治疗后1周, 两组创面愈合率比较差异无统计学意义(P>0.05)。治疗后2、3周, 实验组创面愈合率显著高于对照组, 差异均有统计学意义(P<0.05)。实验组平均愈合时间(18.2±3.4)d明显短于对照组的(28.6±6.8)d, 差异具有统计学意义(P<0.05)。实验组截肢(趾)率为22.7%(5/22), 明显低于对照组的56.3%(9/16), 差异具有统计学意义(P<0.05)。除3例脱访(实验组2个, 对照组1个), 其余患者随访6个月。实验组复发率为13.6%(3/20), 明显低于对照组的46.7%(7/15), 差异具有统计学意义(P<0.05)。结论 PRP可以有效的促进糖尿病足难愈性创面的愈合, 缩短住院时间, 降低截肢(趾)率, 减少复发率, 明显改善患者的生活质量。

【Abstract】 Objective   To observe the clinical efficacy of platelet-rich plasma (PRP) on diabetic foot refractory wounds. Methods   A total of 38 diabetic foot patients were divided into experimental group (22 cases) and control group (16 cases) by different treatment methods. The control group was treated by conventional therapy, and the experimental group was treated by PRP on the basis of the control group. The wound healing rate 1, 2 and 3 weeks after treatment, healing time, amputation (toe) rate and wound recurrence rate were compared between the two groups. Results   1, 2 and 3 weeks after treatment, the wound healing rate of the experimental group were (26.6±5.5)%, (58.4±8.4)% and (93.6±9.2)%, which were (21.8±5.7)%, (38.7±6.8)% and (62.5±9.3)% respectively. 1 week after treatment, there was no statistically significant difference in wound healing rate between the two groups (P>0.05). 2 and 3 weeks after treatment, the wound healing rate of the experimental group were significantly higher than those of the control group, and the difference was statistically significant (P<0.05). The average healing time (18.2±3.4) d of the experimental group was obviously shorter than that of the control group (28.6±6.8) d, and the difference was statistically significant (P<0.05). The amputation (toe) rate of the experimental group was 22.7%(5/22), which was obviously lower than that of the control group 56.3%(9/16), and the difference was statistically significant (P<0.05). Except for 3 patients (2 cases in the experimental group and 1 case in the control group) lost to follow-up, the remaining patients were followed up for 6 months. The recurrence rate of the experimental group was 13.6%(3/20), which was obviously lower than that of the control group 46.7%(7/15), and the difference was statistically significant (P<0.05). Conclusion   PRP can effectively promote the healing of diabetic foot refractory wounds, shorten the hospitalization time, reduce the amputation (toe) rate, reduce the recurrence rate, and significantly improve the patients quality of life.

糖尿病足难愈性创面是糖尿病后期常见的并发症之一, 预后较差, 其中约14%~24%的患者需行截肢手术[1]。因此, 糖尿病足在很多国家已经成为了截肢的最主要原因。糖尿病足的治疗包括控制血糖、抗感染、营养支持、清创切开引流分等内科治疗, 及介入手术、干细胞移植术、清创术等外科治疗[2, 3]。但是由于糖尿病足的病因复杂, 发病机制也不完全清晰, 其治疗在我国尚无统一标准和合理的规范治疗方案, 临床也很少专门的治疗科室。因此对于复杂性、难治性糖尿病足的治疗整体水平还非常有限, 导致很多患者无法得到专业、及时、系统、有效的治疗, 导致严重后果。2018年1月~2019年6月本科开始尝试采用PRP治疗一些严重糖尿病足难愈性创面, 取得比较好的疗效。现报告如下。
