Key result
TEE provides critical therapeutic benefits not seen with TTE in ~46% of patients.
Why the study?
It remained largely unknown whether TEE is a clinically valuable replacement or supplement for TTE as a primary tool for evaluating haemodynamic problems in critically ill surgical patients.
Does transesophageal echocardiography (TEE) improve diagnostic and therapeutic value compared to transthoracic echocardiography (TTE) alone in intubated critically ill surgical patients with hemodynamic instability?
Population
68 consecutive critically ill surgical patients with hemodynamic instability
Comparison
Routine TEE in addition to TTE vs TTE information alone
Design
Prospective observational study

May support TEE addition when TTE views are inadequate in unstable surgical patients; leaves open whether RCTs confirm outcome benefits.

Does transesophageal echocardiography (TEE) improve diagnostic and therapeutic value compared to transthoracic echocardiography (TTE) alone in intubated critically ill surgical patients with hemodynamic instability?
Absolute Event Rate: 54.3% vs 27.3%
p-value: p=0.036
In intubated critically ill surgical patients, adding TEE to TTE significantly alters clinical management, particularly when TTE image quality is inadequate.
Si et al. (2020) conducted an observational in Critically ill surgical patients with hemodynamic instability (n=68). Transesophageal echocardiography (TEE) vs. Transthoracic echocardiography (TTE) was evaluated on Critical therapeutic benefits not provided by TTE (p=0.036). Transesophageal echocardiography provided critical therapeutic benefits not seen with TTE in 45.6% of patients, especially those with inadequate TTE views (54.3% vs 27.3%, P=0.036).
