Clinical Trial Summary

A quasi experimental study that aims to verify whether the incorporation of VExUS in patients with AKI in the Intensive Care Unit (ICU) may prompt tailored interventions to increases the number of days free from Renal Replacement Therapy (RRT) during the first 28 days.

Description:

Fluid overload is associated with organ dysfunction, such as Acute Kidney Injury (AKI), and increased mortality. It remains unclear if fluid overload is merely an epiphenomenon in critically ill patients or if organ congestion is a mediator of complications. Considering AKI related to fluid overload, diuretic therapy would reduce venous congestion and improve renal blood flow. The Venous Excess Ultrasound score (VExUS) identifies clinically significant venous congestion and indicates a high risk of post-operative AKI. This quasi-experimental study aims to verify whether the incorporation of VExUS in patients with AKI in the Intensive Care Unit (ICU) may prompt tailored interventions to increases the number of days free from Renal Replacement Therapy (RRT) during the first 28 days.

Eligibility

Inclusion Criteria:

• RRT before recruitment

• Use of Extracorporeal membrane oxygenation (ECMO)

• Hepatic cirrhosis or other condition with portal hypertension

Intervention

Diagnostic Test:
• VExUS Score
The VExUS-Guided Arm care team will be informed of the Day 0 VExUS immediately after the ultrasound is performed and given a suggested target for the following 48 hours as follows: VExUS 0: There is no evidence of venous congestion. VExUS 1: There is evidence of mild venous congestion. The investigators recommend targeting a net neutral or negative fluid balance with diuresis. VExUS 2-3: There is evidence of moderate to severe venous congestion. The investigators recommend targeting a fluid balance of negative 1-2L with diuresis. If the investigator cannot obtain ultrasound images of sufficient quality to calculate VExUS, the care team will be informed that there is no recommendation for that subject on that day.
