研究目的:

本研究旨在从“浓度-体积-剂量”三维关系探讨全膝关节置换(total knee arthroplasty,TKA)术后相同剂量不同浓度及体积的布比卡因脂质体超声引导下坐骨神经阻滞对TKA术后镇痛效果及足踝部肌力的影响,同时探讨LB对坐骨神经毒性作用机制,评估其有效性和安全性。  

Objectives of Study:

This study aims to evaluate "concentration-volume-dose" relationship of liposomal bupivacaine in sciatic nerve blocks for TKA on the efficiency with same dose but different concentrations and volumes on postoperative analgesia, and including the impact of ankle muscle strength. While also we also investigate the mechanism of neurotoxicity on the sciatic nerve, to assess its efficacy and safety.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用区组随机化,由一位不参与患者招募、麻醉管理和数据收集的研究护士通过计算机在线随机化系统生成伪随机数,按顺序编号将分配结果装入按序列编号的、不透光的密封信封中。

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

This study utilized block randomization. The allocation sequence was generated by a research nurse, who was not involved in patient recruitment, anesthetic management, or data collection, using a computer-based online randomization system. The assignment results were then sealed in sequentially numbered, opaque, sealed envelopes.

IPD sharing

Yes

共享原始数据的方式(说明:请填入公开原始数据日期和方式,如采用网络平台,需填该网络平台名称和网址):

论文发表后将在网络平台共享数据((如Zenodo、Figshare、ScienceDB)):通用型数据存储库Mendeley Data为数据集分配DOI,并与Elsevier旗下论文关联。

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

Data will be shared on web-based platforms (e.g., Zenodo, Figshare, ScienceDB) after publication: Mendeley Data, a generic data repository, assigns DOI to datasets and is linked to Elsevier papers.

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:

数据采集工具为病例报告表(CRF),CRF上的每一个数据点都必须直接对应于研究方案的要求,由参与研究者在受密码保护的电子系统上直接录入数据(对于纸质CRF,采用“双遍录入”法,即由两个不同的录入员分别录入同一份CRF,然后由系统比对差异并核对修正)。

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

The data collection by Case Report Form (CRF). The CRF must directly correspond to the requirements of the study protocol. All the datas are entered directly into a password-protected electronic system by the participating investigators (for paper CRFs, a "double data entry" method is adopted, where two different operators independently enter the same CRF data, followed by a system comparison of discrepancies and verification for correction).
