Abstract

We assessed the effect of music on the level of sedation and the electroencephalograph bispectral index (BIS) during the preoperative period. Fifty-four ASA physical status I-II patients, scheduled for elective septo-rhinoplastic surgery, were included in the study. Subjects were assigned to receive either music (music group; n = 28) or no music (control group; n = 26) during the preoperative period. Sedative premedication was provided with midazolam 0.08 mg/kg IM. Observer's Assessment of Alertness/Sedation Scales (OAAS) scores and BIS values were recorded at specific time intervals. In the control group, there were more patients with an OAAS score of 1 than in the music group at 30 min after midazolam injection. In addition, there were more patients with an OAAS score of 2 in the control group than in the music group at 30-50 min. However, there were significantly more patients with an OAAS score of 3 in the music group than in the control group at 20-50 min. BIS values of the music group were also smaller than the control group at 30 and 40 min. BIS values were significantly decreased from baseline values at 10-50 min in the music group, whereas BIS values decreased at 30-50 min in the control group. In conclusion, listening to music during midazolam premedication is associated with an increase in sedation level in the preoperative period as reflected by a lower BIS value.
