Inferior Vena Cava Abnormality clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT04914455 Recruiting - Fluid Overload Clinical Trials

Transhepatic Echography for Fluid Responsiveness After Cardiovascular Surgery

THEFRACS

Start date: December 8, 2020
Phase:
Study type: Observational

Fluid expansion in critically ill patients following high risk surgery may induce fluid overload and worse outcome. Several tools have been developped to predict fluid responsiveness in such situation in order to avoid inappropriate fluid administration but with several limitations. Inferior vena cava (IVC) distensibility is one of those tools which has the advantage to be non-invasive, dynamic and safe, is usually measured by subcostal (SC)approach. In post surgical setting this acess is limited du to practical reasons (scar, dressing...), therefore a transhepatic (TH) approach is used but has not been validated as a fluid responsiveness prediction tool. The correlation between SC approach with the TH approach vary according to studies. Therefore the performances, the threshold identified for SC approach can not be translated to the TH approach. Further, fluid congestion status measured before IVC analyses, may be a useful confounder and safety endpoint for fluid responsiveness interpretation. The primary objective of this study is therefore to study the performance of the IVC measured using TH approach (IVCth) in predicting of fluid responsiveness defined as an increased of 10% and over of stroke volume. Secondary objectives intend to analyse the correlation between TH and SC approaches, to compared their performances for fluid responsiveness prediction, and to analyse the weight of venous congestion on fluid responsiveness prediction.
