研究目的:

1.分析肾脏CEUS定量参数与经皮肾小球滤过率(TGFR)的相关性,探讨脓毒症患者肾脏微循环灌注障碍与肾小球滤过功能下降的关系。 2.初步评估各超声造影定量参数对脓毒症相关急性肾损伤(S-AKI)的鉴别能力,通过受试者工作特征曲线(ROC)描述其灵敏度、特异度及可能的最佳截断值,为后续开展大样本诊断试验提供基础数据与参考依据。  

Objectives of Study:

1. To analyze the correlation between quantitative parameters of renal contrast-enhanced ultrasound (CEUS) and transdermal glomerular filtration rate (TGFR), and to explore the relationship between renal microcirculatory perfusion impairment and decline of glomerular filtration function in patients with sepsis. 2. To preliminarily evaluate the discriminatory ability of various quantitative CEUS parameters for sepsis-associated acute kidney injury (S-AKI), and to describe their sensitivity, specificity, and potential optimal cut-off values using receiver operating characteristic (ROC) curves, thereby providing basic data and reference for subsequent large-scale diagnostic trials.

是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):

研究完成后,统计学结果会上传到国内公网能查看到的电子采集和管理系统(Electronic Data Capture, EDC),一年后公布结果。

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

After the study is completed, the statistical results will be uploaded to an electronic data capture and management system (Electronic Data Capture, EDC) that is accessible on the domestic public internet, and the results will be released one year later.

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:采用统一印制的纸质病例报告表(CRF)记录数据,内容包括人口学特征、临床基线资料、实验室指标、TGFR测量值及CEUS定量参数。CRF由经培训的研究人员填写,填写后与电子病历源数据100%核对,确保真实、准确、完整。 数据管理:电子数据采集和管理系统(Electronic Data Capture, EDC)进行数据管理。

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

Data collection: Data are recorded using a uniformly printed paper case report form (CRF), including demographic characteristics, clinical baseline data, laboratory indicators, TGFR measurements, and CEUS quantitative parameters. The CRF is completed by trained research staff and is 100% verified against the source data from the electronic medical records to ensure authenticity, accuracy, and completeness. Data management: The electronic data capture and management system (Electronic Data Capture, EDC) is used for data management.
