Fluid Status and Body Composition Analysis by Bioelectrical Impedance in Patients After Cardiac Surgery (FLUBIACS)

Fluid Status and Body Composition Analysis in Patients After Cardiac Surgery Assessed by Bioelectrical Impedance Method and Its Impact on Postoperative Morbidity and Mortality

Evaluation of fluid status in cardiac surgery patients using bioelectrical impedance and its impact on postoperative morbidity and mortality

Hydration and fluid balance dynamics after cardiac surgery is complex and requires comprehensive knowledge of bluid balance dynamics. Surgical trauma, anaesthesia and use of cardiopulmonary bypass significantly influence postoperative fluid status. Deviations from normal values on the other hand can be related to increase in morbidity and mortality.

The purpose of this prospective observational clinical study is to assess fluid status using bioelectric impedance in patients undergoing cardiac surgery and to evaluate its impact on postoperative morbidity and mortality.
