- Brief Summary
Fluid expansion with isotonic crystalloids is a first-line intervention in the treatment of patients with acute kidney injury (AKI). While it is generally accepted that the timely correction of kidney hypoperfusion will minimize the extent of injury as well as potentially facilitate recovery, there are potential harms involved in indiscriminate administration of intravenous fluids. Although anticipating fluid tolerance is part of the clinical evaluation of a patient for whom intravenous fluid therapy is considered, it has been suggested that using Point-Of-Care ultrasound (POCUS) may enable the early identification of patients with a high-risk of congestive complications and guide clinical decisions with greater precision\[1\]. However, it has not been shown that providing this information in the context of AKI result in a change in management or a prevention of complications.
This single-center pilot randomized controlled trial aim to determine the feasibility of comparing a management including a POCUS evaluation of fluid tolerance to usual care in non-critically ill patients with AKI. In the intervention group, a POCUS evaluation will be performed and interpreted by experienced staff producing a report that will be presented to the attending care team. This assessment will be repeated 48-72 hours later. The primary aim of the study will be to establish the feasibility of this intervention. Secondary objectives will include determining the difference between the intervention arm and the control arm in relationship with fluid administration, diuretic use, evolution of kidney function, and intensification of care.

Group Intervention Description Management with ultrasound information Ultrasound evaluation of fluid tolerance An ultrasound report will be provided to the attending care team. The report will contain information related to abdominal and thoracic ultrasound exams with expert interpretation regarding anticipated risks of fluid administration.
- Primary Outcome Measures
Name Time Method Protocol adherence 30 days : Ultrasound assessments were performed as planned and the reports were generated and transmitted to the attending care team in the prespecified periods.
- Secondary Outcome Measures
Name Time Method Cumulative intravenous fluid 5 days Amount of fluid in mL received
Diuretic use 5 days defined as the use of loop diuretics
Kinetic estimated glomerular filtration rate (KeGFR) 5 days Kinetic estimated glomerular filtration rate (KeGFR) will be derived from serial measurements in serum creatinine
Progression to a higher stage of AKI 5 days Progression to a higher stage of AKI will be defined as any increase in the KDIGO staging criteria of increase in creatinine:
Operational definition: Increase in at least one level compared to baseline AKI staging during the first 5 days:
Stage 1: Increase in serum creatinine by ≥26.5 µmol/L within 48 hours or increase to 1.5-1.9 times baseline within the last 7 days.
Stage 2: Increase in serum creatinine to 2.0-2.9 times baseline. Stage 3: Increase in serum creatinine to ≥3.0 times baseline or increase to ≥354 µmol/L, Stage 3D: Initiation of renal replacement therapy.Death or escalation of care 10 days composite endpoint defined as the occurrence of at least one of the following events occurring within 10 days after randomization: death from any cause, intervention of the rapid response team, admission to the intensive care unit, initiation of non-invasive positive pressure ventilation, initiation of renal replacement therapy.
