Official title
Is Cardiac Index, Assessed by Transpulmonary Thermodilution, Reliable During Liver Transplantation Compared to Transesophageal Echocardiography : a Monocentric Cohort
Overview
Liver transplantation poses challenges due to hemodynamic changes throughout different surgical phases. Monitoring devices are essential for therapeutic adjustments. Transpulmonary thermodilution and transesophageal echocardiography are commonly used, but thermodilution may have limitations depending on the surgery. This study aims to compare cardiac index variations between thermodilution and transesophageal echocardiography during liver transplantation. Patients undergo monitoring with both techniques. Measurements are recorded and reported at multiple time points.
Interventions
- Other Measure of cardiac index with thermodilution and transesophageal echocardiography
At 4 times of surgery, end-expiratory occlusion (EEO) test and measure of cardiac index before and after test with ETO and thermodilution - Other Surgical anastomosis echography
Visualisation of surgical anastomosis through transesophageal echocardiography : stenosis, doppler velocity, collar diameter
Primary outcome measures
- Cardiac index variation measured by thermodilution compared with transesophageal echography [Time frame: At 4 times of surgery: after starting anesthesia, anhepatic phase, reperfusion and surgical anastomosis of biliary ducts. Data reported : - Cardiac Index before and after end-expiratory test. - Transoesophageal echography measurement of cardiac function]
