诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

10min内通过中心静脉快速输注4ml/kg生理盐水进行补液试验,补液试验后SVI较补液试验前增加≥15%,确定为有液体反应性。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

A fluid challenge was performed by rapid administration of 4 mL/kg normal saline via a central venous catheter over 10 minutes. Fluid responsiveness was defined as a >=15% increase in stroke volume index (SVI) post-fluid challenge compared to baseline values.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

呼吸末阻塞和吸气末阻塞诱发的SVI变化百分比的绝对值之和

Index test:

Cumulative absolute percentage changes in SVI following EEO and EIO maneuvers

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

有组织灌注不足的俯卧位通气的ARDS患者

例数:

Sample size:

26

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

ARDS patients undergoing prone ventilation with tissue hypoperfusion

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

例数:

Sample size:

0

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

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:

研究者根据受试者的原始观察记录,将数据及时,完整,正确,清晰地载入病例报告,录入采用相应的数据库双人双机录入,之后对数据库进行两遍比对。电子数据文件分类保存,并有多个备份保存于不同磁盘或记录介质上,妥善保存,防止损坏。

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

Based on the original obseavation records, reseachers will completely write accurate data into case report forms in time. Input the data into corresponding database system by two special reseachers with two computers respectively. After that, reseachers compare two database twice and electronic data will be conserved and backup.
