    AbstractThis study aimed to identify the anesthetic-sparing effect of different intraoperative sound on sedated patients under propofol target controlled infusion anesthesia (TCI). 90 patients scheduled for transvaginal oocyte retrieval surgery (TVOR) were available and randomized into three groups: patients isolated from background noise(S), patients listened to a voice calling their names (CN), or patients listened to the classical music (CM). The main outcome was the value of total propofol consumption/surgical time. In the result, the value of total propofol consumption/surgical time for the CM group was 22.48% lower than CN group. The value of ΔEntropy and ΔCE for the CM group were also lower than that for the CN group (-2.17 ± 4.13 vs. 1.33 ± 3.43, P-value<0.001) (-0.17 ± 0.28 vs. 0.07 ± 0.25, P-value<0.001). We concluded that participants under propofol TCI who were listening to classical music had lower CE value, Entropy level and reduced 22.48% total propofol consumption/surgical time compared to those called by their names.Copyright © 2020 Formosan Medical Association.
