What this trial studies

This multicentric randomized controlled trial aims to compare two fluid resuscitation strategies in patients with septic shock requiring further fluid administration. The intervention group will utilize fluid intolerance signals to guide fluid administration, while the control group will follow standard care for a duration of six hours. The study will assess the impact of both strategies on fluid-induced harm by measuring changes in pulmonary, cardiac, and renal function biomarkers, as well as the resolution of hypoperfusion through capillary refill time and lactate levels. The goal is to identify early signs of fluid intolerance to prevent adverse outcomes associated with fluid overload.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed or suspected of having septic shock, requiring further fluid resuscitation, and exhibiting signs of hypoperfusion.

Not a fit: Patients who may not benefit include those with do-not-resuscitate status, severe acute respiratory distress syndrome, or other severe comorbidities that complicate fluid resuscitation.

Why it matters

Potential benefit: If successful, this approach could significantly reduce fluid-induced harm and improve outcomes for patients with septic shock.

How similar studies have performed: While the integration of fluid intolerance signals is a novel approach, previous studies have highlighted the importance of managing fluid resuscitation in critically ill patients, suggesting potential for success.
