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.

Conditions

• Liver Transplantation

Interventions

Type	Name	Description
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
