研究目的:

主要探讨椎间盘源性腰痛患者进行PRP(富血小板血浆)注射术后症状(疼痛及功能评分)的改变以及影像学(定量核磁)上的改变,包括它们之间的相关关系。研究人群为患者为椎间盘源性腰痛的患者,通过比较术前1天,术后1,3,6月随访的不同疼痛及功能评分以及定量核磁的改变,来判断经过PRP治疗的盘源性腰痛的患者的疗效。主要结果指标包括了术前及术后随访所收集疼痛及功能评分量表,定量核磁影像学上T2值数值,脂肪分数等的改变。次要结果包括手术中椎间盘的节段、术中穿刺数量、椎间盘退变程度,术后住院时间,以及术后并发症等等。通过患者症状上的及影像学上的改变来判断PRP作为一项治疗椎间盘源性腰痛的方法有效性如何,优势何在。  

Objectives of Study:

To investigate the changes in symptoms (pain and function scores) and changes in imaging (quantitative nuclear magnetic resonance) after PRP(plate-rich plasma) injections in patients with discogenic low back pain, including the correlation between them. The study population consisted of patients with discogenic low back pain, and the efficacy of patients with discogenic low back pain treated with PRP was determined by comparing the changes in different pain and function scores and quantitative nuclear magnetic changes at 1 day preoperatively, and at 1,3, and 6-month postoperative follow-up. The primary outcomes included changes in pain and function scores, T2 values, and fat scores on quantitative MRI collected at preoperative and postoperative follow-up. Secondary outcomes included the number of disc segments operated on, the number of intraoperative punctures, the degree of disc degeneration, the length of postoperative hospitalization, and postoperative complications. Symptomatic and imaging changes in patients were used to determine the effectiveness and advantages of PRP as a treatment for discogenic low back pain.

药物成份或治疗方案详述:

治疗患者所使用的富血小板血浆为术中制备,有手术室护士老师在手术医生穿刺定位成功后抽取患者静脉血液约25ml,放入专用离心机里,设置离心参数为1500转每分钟,离心5分钟,将离心所得的上层血浆抽出用于注射用,制备过程中操作时间较短,不加入抗凝剂及其他药品。所使用的血小板制备器为德国锐适公司的富血小板血浆制备器。 

Description for medicine or protocol of treatment in detail:

The platelet-rich plasma used for treating patients was prepared intraoperatively, with the operating room nurse teacher extracting about 25ml of the patient's venous blood after the surgeon's successful puncture and positioning, placing it into a special centrifuge, setting the centrifugation parameter at 1,500 rpm and centrifuging it for 5 minutes, and then drawing out the upper layer of plasma obtained from centrifugation for injections, which was a shorter operation in the process of preparation, and did not add anticoagulants and other medicines. The platelet preparator used was the :Arthrex ACP Double Syringe , Germany.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection: pain and functional scores were collected through offline and online questionnaires, imaging parameters (quantitative nuclear magnetic resonance imaging) were collected by the imaging faculty and uploaded to the hospital's PACS system, and intraoperative preoperative and imaging secondary outcomes were collected by outpatient clinic faculty, postgraduate students involved in the surgery, and postgraduate students on follow up. Data management: managed through the creation of a medical record chart.
