About

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.

Enrollment: 30 estimated patients

Sex: All

Ages: 18+ years old
