研究目的:

通过前瞻性随机对照试验,验证体外膈肌起搏器(EDP)联合体位管理(PM)相较于对照组(常规干预+PM),能否显著提高重症脑卒中机械通气患者的撤机成功率,并缩短撤机时间。  

Objectives of Study:

Through a prospective randomized controlled trial, verify whether extracorporeal diaphragm pacing (EDP) combined with postural management (PM) can significantly improve the weaning success rate of mechanically ventilated patients with severe stroke, and shorten weaning time, compared with the control group (conventional intervention PM).

本研究将使用纸质病例报告表进行原始数据采集。所有数据将由双人独立录入电子数据库(如EpiData),并进行逻辑核对与范围核查以确保数据质量。数据库将进行密码保护并定期备份。

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

This study will utilize paper-based Case Report Forms (CRFs) for original data collection. All data will be independently entered into an electronic database (e.g., EpiData) by two data entry clerks, followed by logical consistency checks and range validation to ensure data quality. The database will be password-protected and regularly backed up.
