Why the study?
Does the pressure produced by contact between a transesophageal echocardiography (TEE) probe and the esophagus cause esophageal damage in anesthetized dogs and humans?
Population
Anesthetized dogs and 6 human patients (one with intrathoracic pathology).
Design
Preclinical
Follow-up
Up to 12 hours in dogs; short-term in humans

Alerts to high-pressure risk during TEE with intrathoracic pathology; leaves open need for prospective human safety studies.
Does the pressure produced by contact between a transesophageal echocardiography (TEE) probe and the esophagus cause esophageal damage in anesthetized dogs and humans?
TEE probe contact generally produces low esophageal pressures without tissue damage, but dangerously high pressures can occur in patients with intrathoracic pathology.
Urbanowicz et al. (1990) studied this question.
