The Ability of Polyuria in Prediction of Weaning Outcome in Critically Ill Mechanically Ventilated Patients.

Background: Fluid balance and oliguria influence outcome in critically ill patients. Although, osmotic dieresis with hypernatraemia is a predictor of mortality in critically ill patients, the purpose of this study was to demonstrate the effect of polyuria as an independent predictor on weaning outcome in mechanically ventilated patients.

Materials And Methods: This retrospective, single center, cohort study was carried out at Imam Teaching Hospital Intensive Care Unit (ICU) on 263 adult mechanically ventilated patients.
