Utility of transesophageal echocardiography in the ICU: a preliminary US perspective
Critical Care volume 17, Article number: P182 (2013)
While TEE is providing a direct assessment of the cardiac function and volume status as a diagnostic tool, until recently it has been impractical to be continuously available for monitoring. A new disposable, monoplanar TEE probe (ImaCor) can remain in the patient for up to 72 hours, allowing repeated measures of ventricular function and volume status, parameters needed to monitor response to therapy.
We assessed the benefit these TEE data provided in the assessment of five domains: hypovolemia, right ventricular dysfunction, left ventricular dysfunction, sepsis, and valvular abnormality. Bedside practitioners listed their diagnoses before and after seeing primary TEE images perform by trained physicians. We used a 0 to 5 Likert scale to assess differential diagnosis before and after the TEE, comparing changes using a paired t test.
All requests for TEE were to access hemodynamic instability. A total of 18 patients were screened and nine were eligible, in which 16 total TEE studies were performed. There were no complications with TEE and all patients tolerated the long-term placement of the probe well. Of the five diagnostic domains studied, right ventricular failure was the most commonly underdiagnosed contributor to the hemodynamic instability among patients prior to TEE (P = 0.054) (Figures 1 and 2).
Our results suggest that having continuously available TEE for monitoring and management of hemodynamically unstable patients increases awareness of right ventricular dysfunction in the ICU.
