Before inserting the probe, mild to moderate sedation is induced in the patient to ease the discomfort and to decrease the <a href="/wiki/Gag_reflex" class="mw-redirect" title="Gag reflex">gag reflex</a>. Usually a local anesthetic spray (e.g., <a href="/wiki/Lidocaine" title="Lidocaine">lidocaine</a>, <a href="/wiki/Benzocaine" title="Benzocaine">benzocaine</a>, <a href="/wiki/Xylocaine" class="mw-redirect" title="Xylocaine">xylocaine</a>) is used for the back of the throat or as a jelly/lubricant anesthetic for the esophagus. Sedation and anesthesia are required to make the procedure tolerable and safer, as biting the probe, coughing, vomiting, and patient movement would drastically reduce the value of the procedure.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

From here, the protocol used for the procedure is highly variable. As the study could be terminated any second (e.g., respiratory compromise, hypotension, intolerance to the probe) the structures of particular interest could be visualized first. For example, if the TEE is ordered to look for <a href="/wiki/Mitral_regurgitation" title="Mitral regurgitation">mitral regurgitation</a> then the mitral valve may be fully inspected first.

Comparatively, transthoracic ultrasound must first traverse skin, fat, ribs and lungs before reflecting off the heart and back to the probe before an image can be created.
