This is the authors' abstract. We don't add key points for this paper.

INTRODUCTION: The study aimed to assess the applicability of the ROSE conceptual framework (Resuscitation, Optimization, Stabilization, Evacuation) for fluid therapy in critically ill pediatric patients, focusing on its distinct phases, prevention of fluid accumulation, and clinical outcomes. MATERIAL AND METHODS: A quasi-experimental study was conducted including 122 (retrospective: n = 71; prospective: n = 51) mechanically ventilated and vasoactive-dependent children. A retrospective cohort was compared with a prospective cohort following structured training on ROSE-guided fluid management. Outcomes included fluid accumulation percentage (FA%), duration of mechanical ventilation, pediatric intensive care unit (PICU) length of stay, and need for renal replacement therapy (RRT). Adherence to phase-specific FA% targets was also assessed. RESULTS: FA% was similar between cohorts (retrospective vs. prospective) on PICU days 1, 3, and 10 (median [IQR] 1.8% [0.2-4.3] vs. 1.9% [0.8-3.2], P = 0.934; 5.5% [1.7-10.3] vs. 6.1% [3.8-10.2], P = 0.565; 8.3% [0.8-24.8] vs. 7.2% [2.6-18.7], P = 0.848). By ROSE phase, FA% was comparable in Resuscitation (3.5% [2.0-6.0] vs. 4.7% [2.4-6.9], P = 0.244), Optimization (3.0% [0.1-6.7] vs. 4.2% [1.0-7.9], P = 0.261), and Evacuation (2.5% [-2.6-5.3] vs. 2.4% [-0.0-7.4], P = 0.256), but higher during Stabilization (2.5% [0.0-6.9] vs. 4.2% [2.0-8.9], P = 0.043). Mechanical ventilation, length of PICU stay, RRT, and fluid elimination were similar. No independent predictors emerged in logistic regression. FA% target adherence rose from 67.9% to 72.4% after ROSE. CONCLUSIONS: The ROSE framework in pediatric fluid management is feasible, provides benchmarking for FA% control, and shows promise for individualizing fluid management. Future validation in ROSE-naive centers is warranted.
