Abstract EN
A pilot study aimed to introduce intraoperative monitoring of liver surgery using transoesophageal echocardiography (TEE) is described.
A set of TEE measurements was established as a protocol, consisting of left atrial (LA) dimension at the aortic valve plane; mitral velocity flow integral, calculation of stroke volume and cardiac output (CO); mitral annular plane systolic excursion; finally, right atrial area.
A total of 165 measurements (on 21 patients) were performed, 31 occurring during hypotension.
The conclusions reached were during acute blood loss LA dimension changed earlier than CVP, and, in one patient, a dynamic left ventricular (LV) obstruction was observed; in 3 patients a transient LV systolic dysfunction was documented.
The comparison between 39 CO paired measurements obtained by TEE and PiCCO2 revealed a statistically significant correlation (P<0.001, r=0.83).
In this pilot study TEE successfully answered the questions raised by the anesthesiologists.
Larger cohort studies are needed to address this issue.
