Investigational drug(s) / intervention(s)

fluid challenge →

fluid challenge: Signs of venous congestion and microcirculatory status will be assessed at baseline. A fluid challenge will then be performed, and microcirculation will be evaluated at the end of fluid administration and again after 30 minutes

Study summary

The hypothesis is that fluid-responsive patients who show signs of venous congestion experience a worsening of microcirculatory status after fluid administration compared to patients without signs of venous congestion

Inclusion Criteria: * Critically ill patients admitted to the intensive care unit * Invasive or minimally invasive hemodynamic monitoring Exclusion Criteria: * Suspected or confirmed pregnancy * Inability to access the oral cavity (e.g., facial trauma, oral bleeding)

Primary outcome measure(s)

  • Change in Sublingual total vessel density (TVD) — Baseline, immediately post-fluid challenge, and 30 minutes post-fluid challenge
    To compare changes in sublingual microcirculatory parameter - total vessel density (TVD) - before fluid administration, immediately after volume expansion, and 30 minutes post-fluid administration in preload-dependent patients with and without signs of venous congestion.
