随机方法(请说明由何人用什么方法产生随机序列):

产生和保存随机分配序列的人员不参与试验。本研究将采用区组随机化。设定好区组长度为4,则有六种排列方式1. AABB, 2. ABAB, 3. ABBA, 4. BAAB, 5. BABA, 6. BBAA,然后依据随机数字表, 如果第一个数字是5,则组内第一个区组(BABA),前4个病人就是 BABA(A是试验组和B是对照组)。最终生成本研究的区组随机表格。根据区组随机表格将患者分配至布比卡因脂质体组或假阻滞组。每个研究对象所接受的治疗方案由产生的随机分配序列产生,并被放入按顺序、密封、不透光的信封中,由不参与研究的麻醉护士打开信封进行配药和推药,使用屏蔽颜色的注射器和连接管保证盲法。

Randomization Procedure (please state who generates the random number sequence and by what method):

The personnel responsible for generating and preserving the random allocation sequence do not participate in the trial. This study will employ block randomization. With a block length set to 4, there are six possible arrangements: 1. AABB, 2. ABAB, 3. ABBA, 4. BAAB, 5. BABA, 6. BBAA. Then, based on a random number table, if the first number is 5, the first block within the group (BABA) will have the first four patients as BABA (where A represents the experimental group and B represents the control group). Ultimately, a block randomization table for this study will be generated. Patients will be allocated to either the bupivacaine liposome group or the sham block group according to the block randomization table. The treatment regimen received by each study subject is generated by the random allocation sequence and placed in sequential, sealed, opaque envelopes, which are opened by anesthetic nurses not involved in the study for medication preparation and administration, using syringes and connecting tubes of a shielded color to ensure blinding.

盲法:

本研究将采用双盲研究方法。患者,主管骨折医生,神经阻滞操作者,随访人员对分组完全不知情。神经阻滞操作者为麻醉医生,同时负责局麻药中毒等特发事情的处理,以保证患者的安全。

Blinding:

This study will adopt a double-blind research method. Patients, the supervising orthopedic surgeons, the nerve block operators, and the follow-up personnel are completely unaware of the group assignments. The nerve block operator is an anesthesiologist who is also responsible for managing any emergencies related to local anesthetic toxicity to ensure patient safety.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

使用病例记录表进行数据采集。本研究是双盲研究方法。参与者,阻滞操作者,疼痛评分的随访人员,骨科医生对研究设计和分组情况并不知情。采血操作由不参与研究且不知情的麻醉护士执行。电子镇痛泵的数据收集由不参与本研究其他工作的专门负责人提取。结果指标的记录按照盲法方案进行记录。

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

Use a case record form for data collection. This study is a double-blind study method. Participants, block operators, follow-up staff for pain scores, orthopedic surgeons were blinded to the study design and grouping. Blood collection operations are performed by nurse anesthetists who are not involved in the study and are not aware. Data collection for electronic analgesic pumps was extracted by a dedicated person in charge who was not involved in other work in this study. Outcome indicators were recorded in a blinded scheme.
