Ultrasound Evaluation of Fluid Tolerance and Fluid Responsiveness in Postoperative Cardiac Surgery Patients (NCT07792707)
Ultrasound Evaluation of Fluid Tolerance and Fluid Responsiveness in Postoperative Cardiac Surgery Patients: A Pilot Randomized Controlled Trial
🩺 Plain-English Summary (8th-Grade Level)
This pilot randomized controlled trial will evaluate the use of point-of-care ultrasound (POCUS) to assess fluid tolerance and fluid responsiveness in patients following cardiac surgery. Participants will be randomized to an ultrasound-guided assessment strategy or standard care. In the intervention group, treating physicians will receive the results of a structured ultrasound assessment, including the Venous Excess UltraSound (VExUS) score and an assessment of fluid responsiveness. The primary objectives are to determine whether this information influences clinical management and to assess the feasibility of the study procedures. The study will also explore differences in fluid and hemodynamic management, kidney function, and postoperative clinical outcomes.
