Comparing Montiroing Cardiac Index by Transpulmonary Thermodilution and Transesophageal Echocardiography During Liver Transplantation

Condition(s) studied

Investigational drug(s) / intervention(s)

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

Surgical anastomosis echography: Visualisation of surgical anastomosis through transesophageal echocardiography : stenosis, doppler velocity, collar diameter

Study summary

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.

Eligibility

Primary outcome measure(s)

• Cardiac index variation measured by thermodilution compared with transesophageal echography — 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
