What this Trial Is About

Introduction: Sepsis is a life-threatening organ dysfunction caused by a dysregulated host immune response to infection, and it is a common critical condition in the ICU. Early and timely fluid resuscitation is the cornerstone of sepsis treatment. However, excessive fluid loading can lead to interstitial edema and iatrogenic organ damage, particularly acute kidney injury (AKI). The VExUS grading system is a recently developed system that measures venous congestion through bedside ultrasound by assessing the blood flow waveforms of the portal vein, hepatic vein, and intrarenal veins, as well as the diameter of the inferior vena cava. Similarly, CVP is a commonly used indicator of venous congestion. The objective of this study is to Investigate the association between Venous Excess Ultrasound Score (VExUS), Central Venous Pressure (CVP) during the first three days of ICU admission, and the composite clinical outcome of major adverse kidney events within 30 days (MAKE 30) in sepsis participants. Methods: This study is a prospective, multicenter, observational study that will recruit at least 120 participants across multiple centers. Based on the definition of sepsis3.0, Participants with sepsis who are older than 18 years. Using Doppler ultrasound, Investigator will measure the IVC, HV, PV, and IRV, as well as lung ultrasound scores and cardiac-related parameters at 0-24 hours, 24-48 hours, and 48-72 hours after enrollment. Investigator will receive web-based educational courses, and image acquisition and interpretation will be adjudicated. The primary outcome is the relationship between VExUS score combined with CVP and MAKE 30 in sepsis participants.
