Abstract

AbstractIt is crucial to consider the possible influence of anesthetic agents on esophageal function testing. Dexmedetomidine has been shown to affect primary peristalsis during esophageal manometry. In the two case reports presented by Toaz et al., secondary peristalsis during FLIP panometry was also affected. This may be attributed to an alternate pharmacodynamic effect, with a transient direct α2‐mediated effect on esophageal smooth muscle, associated with a high plasma concentration following bolus injection, prior to the onset of sympathetic inhibition.
