What this trial studies

This observational study aims to provide a comprehensive description of fluid administration modalities during the first five days of ICU admission for critically ill patients. It will assess the overall fluid balance, characteristics of the fluids given, and the modalities of fluid administration. Additionally, the study will explore associations between fluid administration characteristics and clinical outcomes, utilizing statistical analyses to identify patterns and relationships. The findings will help understand current practices and their impact on patient outcomes in intensive care settings.

Who should consider this trial

Good fit: Ideal candidates for this study are adult patients aged 18 and older who are admitted to the ICU and expected to stay for at least 48 hours.

Not a fit: Patients who are moribund with an expected survival of less than 24 hours or those admitted for planned overnight ICU stays may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve fluid management strategies in critically ill patients, potentially enhancing their recovery and outcomes.

How similar studies have performed: Previous studies, including the original FENICE study, have highlighted variability in fluid administration practices, indicating that this area of research is both relevant and necessary for improving patient care.
