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.

Nature of non-transferrin-bound iron: studies on iron citrate complexes and thalassemic sera.

Despite its importance in iron-overload diseases, little is known about the composition of plasma non-transferrin-bound iron (NTBI). Using 30-kDa ultrafiltration, plasma from thalassemic patients consisted of both filterable and non-filterable NTBI, the filterable fraction representing less than 10% NTBI. Low filterability could result from protein binding or NTBI species exceeding 30 kDa.
