摘要:

文题释义:
富血小板血浆:通过梯度离心方法从自体外周血中获得的富含高浓度血小板和白细胞的血浆,其含有大量的生长因子和细胞因子,可以较长时间持续附着于伤口,持续发挥消炎、促进创面炎性细胞迁移的作用,从而促进组织修复及创面愈合。
脊髓损伤:由于外界直接或间接因素导致脊髓损伤,损伤平面以下失去神经支配,出现运动、感觉和括约肌功能障碍、肌张力异常及病理反射等相应改变。脊髓损伤后,患者对受压产生的痛觉减退或者消失,无自主减压保护机制、肌力下降造成外周血管阻力降低,局部血管淤血,组织营养下降;加上尿便失禁,局部潮湿,容易发生压力性损伤。

背景:研究报道富血小板血浆可以激活和加速压力性损伤的愈合。
目的:探讨富血小板血浆治疗脊髓损伤患者压力性损伤的效果。
方法:选择2017年7月至2019年12月四川大学华西医院康复医学中心收治的脊髓损伤并发3期、4期压力性损伤患者40例,按照随机数字表法分2组,每组20例:对照组进行常规伤口护理及标准化的康复干预,观察组在常规伤口护理及标准化康复治疗的基础上进行自体源性富血小板血浆干预,每周1次。干预前及干预后2,4,6,8周,采用压疮愈合量表(pressure ulcer scale for healing,PUSH)动态评估伤口面积、伤口类型、渗液量,比较两组总分、各条目得分及临床综合疗效。研究获得四川大学华西医院生物医学伦理委员会批准[批准号:2019年审(622)号]。
结果与结论:①观察组干预后各时间点的PUSH评分总分及伤口面积、伤口类型、渗液量评分低于干预前(P < 0.01),对照组干预后6,8周的PUSH评分总分及伤口面积、伤口类型、渗液量评分低于干预前(P < 0.01);②观察组干预后4,6,8周的PUSH评分总分与渗液量评分低于对照组,干预后6,8周的伤口类型评分低于对照组(P < 0.01);③观察组治疗后的显效率高于对照组(100%,35%,P < 0.001);④结果表明,富血小板血浆治疗脊髓损伤压力性损伤具有明显的疗效。

Abstract: BACKGROUND: Studies have reported that platelet-rich plasma (PRP) can promote accelerated healing of pressure injury.
OBJECTIVE: To explore the effect of PRP on pressure injury of patients with spinal cord injury. 
METHODS: From July 2017 to December 2019, 40 patients with spinal cord injury complicated by stage 3 and stage 4 pressure ulcers were randomly divided into a PRP group (n=20) and a control group (n=20) using a random number table. Patients in the control group were given routine wound care and standardized rehabilitation treatment, whereas those in the PRP group received PRP treatment based on routine wound care and standardized rehabilitation treatment once a week. The surface area, wound type and exudate volume were assessed by pressure ulcer scale for healing (PUSH) before treatment and 2, 4, 6, 8 weeks after treatment. The total PUSH score, score of each item in the PUSH scale, and clinical efficacy were compared between the two groups. An ethical approval was obtained from the Biomedical Ethics Committee of West China Hospital of Sichuan University, with an approval No. 2019(622).
RESULTS AND CONCLUSION: The total PUSH score and scores in terms of wound area, type, and exudate volume were significantly reduced after treatment in the PRP group (P < 0.01), while those scores in the control group were also significantly reduced at 6 and 8 weeks after treatment (P < 0.01). Compared with the control group, the total PUSH score and scores on exudate volume were significantly lower in the PRP group at 4, 6, and 8 weeks after treatment, and the scores on wound type were significantly lower in the PRP group at 6 and 8 weeks after treatment. The healing rate in the PRP group was 100% after treatment, which was significantly higher than that in the control group (35%; P < 0.001). These findings indicate that PRP treatment contributes to the recovery of pressure injury in patients with spinal cord injury.
