Ultrasound Evaluation of Fluid Tolerance and Fluid Responsiveness in Postoperative Cardiac Surgery Patients
Sponsor: Centre hospitalier de l'Université de Montréal (CHUM)
Summary
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.

Interventions
Structured Point-of-Care Ultrasound Assessment
A structured point-of-care ultrasound assessment combining evaluation of fluid tolerance using the Venous Excess UltraSound (VExUS) score and assessment of fluid responsiveness. Results are communicated to the treating physician to support postoperative fluid and hemodynamic management.
Standard Care (in control arm)
Participants will receive standard postoperative fluid and hemodynamic management. Study-specific point-of-care ultrasound assessment results will not be communicated to the treating physician.
