研究目的:

间歇性Pringle手法(IPM)作为肝脏切除手术减少出血的手段在各大外科指南中被强烈推荐,同时其相关的肠淤血再灌注损伤的问题也受到关注,既往动物实验发现门静脉阻断超过30分钟的大鼠出现肠上皮细胞坏死。然而,目前还没有专门针对IPM相关肠淤血再灌注损伤问题的研究。根据前期研究结果我们提出超声引导PVB在肝脏手术中作为复合麻醉的多模式镇痛方案,对肠功能的恢复有促进作用,因此我们预测PVB可能通过某种机制改善了IPM相关肠损伤,这是该项目拟解决的关键科学问题。本研究旨在阐明这一问题,并评估PVB对IPM相关肠损伤是否有保护作用并探究其机制。  

Objectives of Study:

Intermittent pringle maneuver(IPM) is recommended in major surgical guidelines as a means to reduce bleeding during liver resection, and its associated problems of intestinal congestion reperfusion injury have also attracted attention. Previous animal experiments have found that intestinal epithelial cell necrosis occurs in rats with portal vein occlusion for more than 30 minutes. However, there have been no studies that specifically address the issue of IPM-related intestinal congestion reperfusion injury. According to the results of previous studies, we proposed that ultrasound-guided PVB, as a multimodal analgesic program of combined anesthesia during liver surgery, can promote the recovery of intestinal function. Therefore, we predicted that PVB might ameliorate IPM-related intestinal injury through some mechanism, which is a key scientific issue to be solved by this project. This study aimed to shed light on this issue and to assess whether PVB has a protective effect against Pringle-associated intestinal injury and explore its mechanism.

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:

(1)临床资料收集:为了减少针对人为因素可能引起的各种偏倚,研究者应进行系统培训,了解研究者工作手册,认真学习研究方案各项目的定义,熟练掌握试验相关评定项目的测量方法,并准确填写记录于病例报告书。本研究纸质资料包括知情同意书,受试者入组筛查表,病例报告表等。试验过程中研究者应确保及时填写相关纸质文件,完善纸质文件的收纳整理。整个试验临床资料收集过程接受自查和临床研究中心的监查,体现数据管理规范性和客观性。 (2)电子数据库:纸质版文件资料转变为电子数据库便于研究者进行统计分析,研究者应确保纸质资料中的数据可以完整的录入数据库,并且数据可顺利转移到各项统计分析软件中。数据库设定应与病例报告书观察项目格式一致,以便于数据录入,提高效率和减少操作差错。

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

(1) Clinical data collection: In order to reduce various biases that may be caused by human factors, researchers should conduct systematic training, understand the researcher work manual, carefully study the definition of each item of the research protocol, master the measurement methods of the trial-related assessment items, and accurately fill in and record the case report. Paper data in this study included informed consent form, subject enrollment screening form, case report form, etc. During the experiment, researchers should ensure that relevant paper documents are filled out in time and the storage and arrangement of paper documents are improved. The whole clinical data collection process of the trial was subject to self-examination and the supervision of the clinical research center, which reflected the standardization and objectivity of data management. (2) Electronic database: Paper documents are converted into electronic databases for researchers to perform statistical analysis. Researchers should ensure that the data in paper documents can be entered into the database completely and the data can be transferred to various statistical analysis software smoothly. The database setting should be consistent with the format of the observation items in the case reports to facilitate data entry, improve efficiency and reduce operational errors.
