Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Medicine - Department of Anesthesia Summary: Introduction: Cardiovascular surgeries are major operations that are associated with changes in cardiac output. Electrical Cardiometry is a non-invasive, simple mechanism for estimation of stroke volume and cardiac output. Objectives: we aimed to test the validity of electrical cardiometrey in predicting fluid responsiveness in cardiac surgical patients postoperatively. Materials and Methods: This was an observational study in 38 patients undergoing cardiac surgery, Before and after fluid bolus hemodynamic data was recorded, VTI was measured by TTE as well as SV measured by EC , we evaluated the accuracy of the change in SV after fluid bolus to predict 15% increase in VTI measured by Echocardiography. Results: There was a strong correlation between the change in SV and the change in VTI in predicting fluid responsiveness with Spearman correlation coefficient (95% confidence interval [CI]) of 0.81 (-6.06, +21.05), however there is no correlation between the absolute values of SVEC and VTITTE. Conclusion: Cardiometry can be used as a non-invasive tool to predict positive fluid challenge test in cardiac surgical patients postoperatively and can guide postoperative fluid management in this type of patients
