Study design:

Cohort study 

研究目的:

评估Trendelenburg方法模拟内在补液预测IABP支持患者容量反应性的准确性。具体来说,研究旨在探讨在接受主动脉内球囊反搏(IABP)支持的危重患者中,Trendelenburg体位对容量反应性(通过VTI变化率的升高来定义)的预测能力,以期为临床容量管理提供依据。  

Objectives of Study:

To evaluate the accuracy of the Trendelenburg method in simulating intravascular fluid resuscitation and predicting the volume responsiveness of IABP-supported patients. Specifically, the study aims to explore the predictive ability of the Trendelenburg position for volume responsiveness (defined by the increase in the VTI rate) in critically ill patients receiving IABP support, with the expectation of providing a basis for clinical volume management.

Inclusion criteria

1.Under IABP support; 2.The attending physician decided to attempt small-volume fluid resuscitation, the reasons being hypotension, oliguria, mottled skin or for the purpose of reducing vasopressor drugs; 3.Analgesia, sedation and invasive mechanical ventilation were administered; 4.Sinus rhythm; 5.Signed informed consent.

排除标准:

1.年龄小于18周岁; 2.怀孕 3.同时使用ECMO支持; 4.正在接受CRRT; 5.超声透声性差; 6.明显的主动脉瓣膜反流; 7.颅内高压

Exclusion criteria:

1. Under the age of 18; 2. Pregnant; 3. Using ECMO support simultaneously; 4. Undergoing CRRT; 5. Poor ultrasound transmissibility; 6. Obvious aortic valve regurgitation; 7. Intracranial hypertension
