Application of transesophageal echocardiography combined with FloTrac monitoring in cardiac valve replacement surgery.

ABSTRACT:

Objective

To compare intraoperative hemodynamics between transesophageal echocardiography (TEE) combined with FloTrac vs. TEE with invasive arterial pressure monitoring, and to examine associations with postoperative cognitive dysfunction (POCD) in patients undergoing cardiac valve replacement.

Methods

A retrospective matched-cohort study included 162 patients (81 per group) matched by surgical type, ASA classification, age, and cardiopulmonary bypass time. Hemodynamic parameters were measured at four time points (T1-T4). Linear mixed-effects models assessed group, time, and interaction effects. Exploratory logistic regression preserving the matched design evaluated associations with POCD.

Results

Group effects were significant for heart rate (HR, F = 6.79,
