Summary

The goal of this randomised controlled trial is to compare the cumulative fluid balance over the first 72 h following inclusion guided by mVExUS versus standard of care in critically ill patients with acute kidney injury receiving CRKT . It will also compare the proportion of CRRT-related complications-including intradialytic hypotension and arrhythmias-between patients managed with mVExUS-guided fluid management and those receiving standard care.

The main questions it aims to answer are:

Does fluid removal rate guided by mVExUS will reduce cumulative fluid balance over the course of the first 72 h of CRRT in ICU patients compared to standard care

Participants will:

Get fluid assessment by mVExUS protocol or a strandard care every 8 hours for 72 hours

Interventions

PROCEDURE

mVExUS-guided fluid management

In the intervention arm, mVExUS has to be performed every 24 hours until 72 hours after enrollment. Participants with profile A will have UFNET 0 mL/hr with target fluid balance 0 to +500 mL/day. Patients with profile B will have UFNET 0-20 mL/hr with target fluid balance 0 to -500 mL/day. Patients with profile C will have UFNET 20-40 mL/hr with target fluid balance -500 to -1000 mL/day. Patients with profile D will have UFNET 40-100 mL/hr with target fluid balance neg \>1000 mL/day. This intervention will be combined with serial lactate monitoring in which lactate levels will be measured every 8 h. When the lactate level rises more than 2 or if there is presence of HIRRT (tachycardia, hypotension, mottling or drop in cardiac index), passing leg raising or mini-fluid challenge (crystalloid fluid bolus 200 mL) will be performed to assess fluid responsiveness. If there is fluid responsiveness, UFNET will be stopped. Once lactate is normalized or episode of HIRRT resolved, the UFNET strat
