Study summary

The purpose of the study is to investigate venous congestion using hepatic vein doppler for ICU patients with invasive mechanical ventilastion. The primary outcome is the systolic to diastolic hepatic vein velocity ratio S/D . The objective is to find a significant association between S/D and different congestion indicators.

Study population

Patients were included if they were intubated for more than 24 hours. Patients were excluded if they had chronic end-stage renal disease on admission, atrial fibrillation, cirrhosis, portal thrombosisrefusal to participate, whose non-opposition could not be obtained from themselves or their trusted support person in the event of incapacity or if they were under legal protection.

S/D velocity ratio was measured as well as veinous congesion parameters such as weight variation, cumulative fluid balance, peripheral edema, central venous pressure, urine output and acute kidney failure KDIGO stage.

What researchers measure

Primary outcomes

  1. Systolic to diastolic hepatic vein velocity ratio S/D

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2025 (actual). Primary completion is estimated for Oct 2028, 43 months after the start.

Of 28 observational studies under Hyperemia, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 27. This study's planned 43 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 6, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
