Heart Failure and Hemodynamic Stability During Anesthesia Induction

40 individuals are enrolled to the study after signed informed consent at the day of surgery. The study participants are randomized (non‐blinded) to preoperative fluid therapy (preoperative colloid fluid bolus at 6 ml/kg LBW, Gelofusine™, Fresenius Kabi AB, Sweden) or control (no preoperative fluids) before standardized TCI‐ induction of anesthesia. No other intravenous fluids before anesthesia induction. Preoperative screening of biventricular systolic and diastolic function of the heart and level of venous return is implemented by transthoracic echocardiography approximately one hour before preoperative fluid therapy and anesthesia induction.
