Bio Impedance Electrical Analysis to Predict Outcome After Cardiac Surgery

Segmental multi-frequency bioelectrical impedance analysis are carried out at all patient admitted to our ICU for postoperative care after cardiac surgery with cardiopulmonary bypass. Our objective is to evaluate the relevance of phase angle to predict mortality or a prolonged hospital length of stay. Phase angle is evaluated at ICU admission and will be compared to well-known prognostic scores computed in preoperative (EuroSCORE II) and at day one after surgery (SOFA, CASUS and SAPS II).
