研究目的:

通过膈肌组织多普勒超声监测重症患者的呼气相,分析患者的膈肌多普勒参数与患者长期机械通气相关,尽早采取干预,改善预后  

Objectives of Study:

This study aims to addresscritical questions by integrating respiratory drive modulation with a dual-modal assessment of the diaphragm. Our objectives are: to validate the utility of TDI-derived maximum relaxation rate as a non-invasive surrogate for the gold-standard Pdi-MRR in mechanically ventilated patients; and to elucidate the direct impact of augmented respiratory drive on the rate of diaphragmatic relaxation.

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):

本研究承诺在研究成果(主要结果论文)正式发表后12个月内,向科学界共享去标识化后的个体参与者数据(IPD),共享方式为通过公开的数据存储库(Figshare)? 提供数据集下载链接

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

This study commits to sharing the de-identified individual participant data (IPD) with the scientific community within 12 months after the official publication of the research results (the main result paper). The sharing will be done by providing a download link to the dataset through the public data repository (Figshare)

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:

数据将来自患者的床边护理图表、医疗记录、病理结果、电子监测器和采访亲属。这些数据将被输入纸质数据收集表格,称为护理记录表格(CRF),随后输入电子数据库。数据收集将定期进行,直到最终出院。在计划出院后,未对患者及其家属进行随访。收集的数据将包括上面描述的主要和次要结果。我们还将收集其他数据,包括:1.纳入研究:人口统计学变量(年龄、性别、入院后24小时内的APACHE II评分)和初步诊断。2.在机械通气的第一天以及从第一次成功的自主呼吸试验到拔管期间记录生理参数,包括生命体征、格拉斯哥昏迷量表评分、ACS评分、STAGE评分[6]、呼吸机模式和参数、24小时液体出入量、实验室检查结果、血气分析以及镇静剂和镇痛剂的使用。此外,记录的临床结果参数如下:拔管失败数、气管造口术率、机械通气持续时间、在ICU和医院停留时间、院内肺炎、死亡率和费用。3.拔管时:动脉血气,APACHE II评分,和类固醇的使用。4.拔管后:与拔管相关的并发症、不良事件、再拔管的原因和拔管后呼吸衰竭的原因。5.记录在ICU、住院时间及出院状态。

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

Data will come from patient bedside care charts, medical records, pathology findings, electronic monitors, and interviews with relatives. These data will be entered into a paper data collection form, called a Nursing Record Form (CRF), and subsequently into an electronic database. Data collection will be performed regularly until final discharge. Patients and their families were not followed up after the planned discharge. The data collected will include the primary and secondary outcomes described above. We will also collect additional data including: 1. Included in the study: Demographic variables (age, sex, APACHE II score within 24 hours after admission) and initial diagnosis. Physiological parameters were recorded on the first day of mechanical ventilation and from the first successful spontaneous breathing trial to extubation, including vital signs, Glasgow Coma Scale score, ACS score, STAGE score [6], ventilator mode and parameters, 24-hour fluid intake and output, laboratory test results, blood gas analysis, and use of sedatives and analgesics. In addition, the following clinical outcome parameters were recorded: number of extubation failures, tracheostomy rate, duration of mechanical ventilation, length of stay in ICU and hospital, in-hospital pneumonia, mortality, and costs. 3. Time of extubation: arterial blood gases, APACHE II score, and steroid use. 4. After extubation: complications related to extubation, adverse events, reasons for re-extubation, and reasons for respiratory failure after extubation. 5. ICU stay, length of hospital stay, and discharge status were recorded.
