Feasibility and Accuracy of Core Temperature Measurements Using the Esophageal Temperature Probe Inserted Through the Gastric Lumen of Supraglottic Airway Device in Pediatrics

Asan Medical Center42 enrolled

Overview

In pediatric patients, the accuracy of body temperature measured with an esophageal temperature probe placed through the gastric lumen of the supraglottic airway device is investigated.

Pediatric patients using a supraglottic airway device during general anesthesia are targeted. When the patient enters the operating room, standard monitoring is performed, general anesthesia is induced, a supraglottic airway device is installed, and an anesthesiologist inserts an esophageal thermometer through the gastric lumen. We recorded the body temperature measured in the esophagus, tympanic membrane, temporal artery, and rectum every 10 minutes from 10 minutes after insertion.
