指标中文名:

毛细血管再充盈时间绝对值变化

指标类型:

主要指标

Outcome:

Absolute change in capillary refill time

Type:

Primary indicator

测量时间点:

基线;MAP达标后第15min、30min、1h、3h、6h

测量方法:

CRT测量统一选择右示指腹侧末端,在室温20-26℃、病房常规照明条件下进行。通过使用显微镜玻片压迫食指指腹掌侧直至发白,持续压迫10秒,使用秒表精确计时,释放后用智能手机录像记录回充过程,视频回放读取恢复时间。

Measure time point of outcome:

Baseline; 15 min, 30 min, 1 h, 3 h, 6 h after MAP reaches target

Measure method:

CRT measurement is consistently performed on the volar tip of the right index finger, under room temperature conditions of 20-26°C and typical ward lighting. By pressing the palmar side of the index fingertip with a microscope slide until it turns white, maintaining pressure for 10 seconds, and timing precisely with a stopwatch, the pressure is then released, and the reperfusion process is recorded with a smartphone video. The recovery time is read from the video playback.

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:

病例报告表上有关受试者数据应以受试者编码方式记录,受试者只能通过受试者编码或其姓名首字母缩写识别。 本研究全部原始诊疗数据(包括但不限于病历、检验报告、影像资料等)均保存于南方医院信息系统,不得外传或外送至其他机构。 本研究采用南方医院临床科研数据采集及管理系统进行数据管理,从数据录入到源数据的核查要求到质控数据的质疑解答,最后到数据锁定及导出的操作、确认数据无疑问后,由数据管理员对数据表格进行锁定。数据表格锁定后,由数据管理员导出分析数据库,交统计人员进行统计分析。锁定后的数据不可再编辑,数据表格锁定之后发现的问题,经确认后可在统计分析程序中修正。

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

Subject data on the case report form should be recorded using subject codes; subjects can only be identified by their subject code or the initials of their name. All original clinical data for this study (including but not limited to medical records, test reports, imaging data, etc.) are stored in the Southern Hospital information system and must not be transmitted or sent to other institutions. This study uses the Southern Hospital Clinical Research Data Collection and Management System for data management. From data entry to source data verification, answering queries during quality control, and finally to data locking and export, once the data is confirmed to be without issues, the data administrator locks the data tables. After the data tables are locked, the data administrator exports the analysis database and provides it to the statistical personnel for statistical analysis. Once locked, the data cannot be edited again. Any issues discovered after locking the data tables can be corrected in the statistical analysis program upon confirmation.
