A positive fluid balance is an independent prognostic
... Introduction: Intravenous fluid administration is an essential component of sepsis management, but a positive fluid balance has been associated with worse prognosis. We analyzed whether a positive fluid balance and its persistence over time was an independent prognostic factor in septic patients. Me ...
