Hepatic Doppler to Assess Venous Congestion During Invasive Mechanical Ventilation

What this Trial Is About

Researchers are studying venous congestion in patients who are in the intensive care unit (ICU) and require invasive mechanical ventilation. The study aims to investigate how the systolic to diastolic hepatic vein velocity ratio (S/D) measured by hepatic vein Doppler relates to various indicators of venous congestion. The goal is to find a significant connection between this ratio and congestion markers. This observational study involves measuring the S/D ratio using hepatic vein Doppler ultrasound at specific times: 24 hours after intubation and then every 48 hours until the patient is extubated, for up to 12 weeks. The study does not involve any treatments or interventions but focuses on monitoring and assessing this ultrasound measurement over time. Participants will be assessed through repeated Doppler ultrasound scans and monitoring while on mechanical ventilation. Researchers will collect data on the S/D hepatic vein velocity ratio and relate it to clinical congestion indicators. The study will continue until extubation or for up to 12 weeks, with safety and health closely observed during this period. The main outcome measured is the S/D ratio at scheduled times after intubation.
