Initial placement of TEE probe by observing the position of esophageal opening in advance on improving the success rate of initial placement of TEE probe by observing the position of esophageal opening: a randomized controlled study.

ABSTRACT:

Objective

The objective of this study is to examine the success rate of transesophageal echocardiography (TEE) probe placement and the incidence of postoperative odynophagia based on pre-assessing the exposed position of the esophageal opening within the pharyngeal cavity.

Methods

Sixty-four patients scheduled for elective cardiac surgery under general anesthesia, with a requirement for transesophageal echocardiography (TEE) monitoring, were enrolled in this study. The patients were randomly assigned to either a pre-observation group or a conventional group. In the pre-observation group, the pharyngeal cavity was examined using a video laryngoscope during endotracheal intubation, and the TEE probe was inserted along the pre-observed esophageal opening. In the conventional gr
