研究目的: |
主要目的:探讨颈静脉血流量参数(jVTI、JVI、jmean)与通过中心静脉置管测得的中心静脉压(CVP)之间是否存在相关性。 次要目的:探讨颈静脉血流参数(jVTI、JVI、jmean)与通过动脉波形分析仪(唯捷流)测得的传统血流动力学参数(SVV、PPV)之间是否存在相关性。 |

|
Objectives of Study: |
Primary Objective: To investigate whether there is a correlation between jugular venous blood flow parameters (jVTI, JVI, jmean) and central venous pressure (CVP) measured via central venous catheterization. Secondary Objective: To explore the correlation between jugular venous blood flow parameters (jVTI, JVI, jmean) and conventional hemodynamic parameters (stroke volume variation, SVV; pulse pressure variation, PPV) measured by the arterial waveform analyzer (Vigileo). |

|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Electronic data were collected simultaneously using the operating room monitors in the First Affiliated Hospital of Chongqing Medical University together with wearable ultrasound devices. Patient information of the enrolled subjects was documented in paper-based graduate research notebooks of the First Affiliated Hospital of Chongqing Medical University. |
