Second-generation SADs, which have a gastric channel, can measure TE, and reduce gastric air volume. This study aimed to compare TE, measured using a probe inserted through the SAD gastric channel, with tympanic membrane (TTM) and forehead (TZHF) temperatures, measured using a zero-heat-flux cutaneous thermometer, with rectal temperature (TR).Methods: Temperature was recorded at 10-min intervals from 10 min after probe insertion until completion of surgery. We performed an equivalence test to evaluate whether the TE, TTM, and TZHF were equivalent to TR, with a margin of 0.3\u00b0C. Additionally, intraclass correlation coefficients (ICC) were calculated to assess the reliability of TE and TR at each time point.Results: We included 41 patients in the final analysis. In all patients, the esophageal probe was successfully inserted through the gastric channel of the SAD. When assessing agreement with TR as a reference, TE demonstrated equivalent results at all time points (P &lt; 0.001 at 0, 10, 20, 30, and 40-min intervals and P = 0.018 at the 50-min interval), except at the completion of surgery (P = 0.697). TE also demonstrated good reliability with TR as a reference throughout the surgery (ICC &gt; 0.75).Conclusions: In children with SAD insertion, TE can be accurately and feasibly measured through the SAD\u2019s gastric channel, making it suitable for routine application.<\/jats:p>","DOI":"10.17085\/apm.23150","type":"journal-article","created":{"date-parts":[[2024,10,28]],"date-time":"2024-10-28T04:29:47Z","timestamp":1730089787000},"page":"S105-S112","update-policy":"https:\/\/doi.org\/10.17085\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Feasibility
