In this multicenter cohort of mechanically ventilated adults with shock, adding TELUS to resuscitative TEE was associated with a higher rate of operator-reported identification of shock etiology and was feasible with minimal additional procedure time. Prospective studies with standardized TELUS acquisition and interpretation, independent adjudication, and evaluation of patient-centered outcomes are needed to define clinical scenarios of incremental value.
OBJECTIVES: To describe the utilization, feasibility, and operator-reported diagnostic and management impact of transesophageal lung ultrasound (TELUS) integrated into resuscitative transesophageal echocardiography (TEE) for the assessment of mechanically ventilated adults with shock.
DESIGN: Multicenter observational cohort study using prospectively collected data.
SETTING: Twenty-three hospitals from the Resuscitative Transesophageal Echocardiography Collaborative Registry (rTEECoRe) network.
PATIENTS: From 1213 registry TEE examinations, 379 met the inclusion criteria for shock evaluation or hemodynamic monitoring in mechanically ventilated adults; 96 (25.3%) of these included TELUS.
INTERVENTIONS: None.
MEASUREMENTS AND MAIN RESULTS: TELUS integration was associated with significantly higher operator-reported identification of shock etiology compared with resuscitative TEE alone (86.5% vs. 75.3%; odds ratio [OR], 1.95; 95% CI, 1.02-3.72; p = 0.04). Although overall clinical management changes were more frequently reported in the TELUS group, this difference did not reach statistical significance (78.1% vs. 71.7%; OR, 1.40; 95% CI, 0.82-2.41; p = 0.22). TELUS examinations were associated with longer procedure duration (median 21.5 vs.19.0 min; p = 0.01) and were predominantly performed by intensivists. Pulmonary findings, including B-lines, pleural effusions, consolidations, and A-line patterns, varied in frequency and were occasionally associated with specific respiratory or antimicrobial interventions. Procedure-related complications were rare and similar between groups.
CONCLUSIONS: In this multicenter cohort of mechanically ventilated adults with shock, adding TELUS to resuscitative TEE was associated with a higher rate of operator-reported identification of shock etiology and was feasible with minimal additional procedure time. Prospective studies with standardized TELUS acquisition and interpretation, independent adjudication, and evaluation of patient-centered outcomes are needed to define clinical scenarios of incremental value.
