干预措施:

Interventions:

组别:

常规治疗组

样本量:

32

Group:

Conventional treatment group

Sample size:

干预措施:

创面坏死组织未彻底清除前创面内应用3%过氧化氢溶液冲洗,再用生理盐水注射液冲洗,应用组织剪进行清创。局部应用浸有 0.1%依沙吖啶的无菌纱布湿敷,无菌纱布包扎,创面每日换药 1 次。创面坏死组织彻底清除、无脓性分泌物后,开始入组进行常规治疗,常规治疗方式由临床医生根据创面情况选择创面密闭负压吸引治疗、美皮康等敷料覆盖治疗或依沙吖啶湿敷等治疗,临床医生根据创面情况决定换药频率。

干预措施代码:

Intervention:

Before the necrotic tissue of the wound was completely removed, the wound was rinsed with 3% hydrogen peroxide solution, then rinsed with normal saline injection, and debridement was performed with tissue scissors. Local sterile gauze soaked with 0.1% ethacridine was applied, sterile gauze was bandaged, and wound dressing was changed once a day. After the necrotic tissue of the wound was completely cleared and there was no purulent secretions, the group was enrolled for conventional treatment. The conventional treatment was selected by clinicians according to the wound condition, such as wound closed negative pressure suction treatment, mepican dressing covering treatment or esacridine wet compress treatment. The clinicians determined the dressing change frequency according to the wound condition.

Group:

A-PRF treatment group

Sample size:

干预措施:

创面坏死组织未彻底清除前创面内应用 3%过氧化氢溶液冲洗,再用生理盐水注射液冲洗,应用组织剪进行清创。创面坏死组织彻底清除、无脓性分泌物后,开始入组进行 A-PRF 治疗,主要为制备 A-PRF 凝胶覆盖骨质/ 肌腱/关节囊。A-PRF 制备过程为:采集 5mL 静脉血置于灭菌无添加抗凝剂真空玻璃管,充分摇匀后,立刻置于配平的离心机内,以 1500 转/分的转速离心 14 分钟,静置后,血液样本分 3 层,中间层淡黄色凝胶即为 A-PRF;将其静置于干燥消毒换药弯盘内,以无菌纱布吸附血清,待 A-PRF 成膜后,将其均匀平铺于创面内骨/肌腱/关节囊及周围肉芽组织表面,然后由临床医生根据创面情况选择创面密闭。

干预措施代码:

Intervention:

Before the necrotic tissue of the wound was completely removed, the wound was rinsed with 3% hydrogen peroxide solution, then rinsed with normal saline injection, and debridement was performed with tissue scissors. After the necrotic tissue of the wound was completely cleared and there was no purulent secretion, A-PRF treatment was started in the group, mainly to prepare A-PRF gel to cover the bone/tendon/joint capsule. The preparation process of A-PRF is as follows: 5mL venous blood is collected and placed in A sterilized vacuum glass tube without adding anticoagulant, fully shaken, immediately placed in A balanced centrifuge, centrifuged at 1500 RPM for 14 min. After standing, the blood sample is divided into 3 layers, and the middle layer of light yellow gel is A-PRF. The serum was absorbed with sterile gauze. After A-PRF film was formed, it was evenly spread on the surface of bone/tendon/joint capsule and surrounding granulation tissue, and then wound sealing was selected by clinicians according to the conditions of the wound.
