Aim We evaluated the influence of early fluid overload on critically ill children admitted to a paediatric intensive care unit by examining mechanical ventilation (MV), mortality, length of stay and renal replacement therapy. Methods This retrospective cohort study covered January 2015 to December 2016 and focused on all episodes of MV support that exceeded 24 hours. The fluid overload percentage (FO%) was calculated daily for the first 72 hours and we estimated its effect on outcomes. Results We included 186 MV episodes in 154 patients. The median age was 13.8 months, with an interquartile range (IQR) of 3.8‐34.0 months, and the mortality rate was 12.4%. The median FO% in the first 72 hours was 8.0% (IQR 3.6%‐11.2%). An FO% of ≥10% was associated with higher ventilatory parameters, namely peak inspiratory pressure ( P = .023) and positive end expiratory pressure ( P = .003), and renal replacement therapy ( P = .02) and higher mortality (8.8% vs 19.7%). In a multivariate Cox regression model, FO ≥ 10% at 72 hours was independently associated with longer MV support, but not mortality ( P = .001). Conclusion In a heterogeneous paediatric population given MV, an early cumulative FO of ≥10% was associated with more aggressive ventilatory parameters and prolonged length of MV, but not mortality.
