Listening to Music During Anesthesia Does Not Reduce the Sevoflurane Concentration Needed to Maintain a Constant Bispectral Index
Anesthesia and Analgesia
BACKGROUND: Music reduces stress responses in awake subjects. However, there remains controversy about the role of music or therapeutic suggestions during general anesthesia and postoperative recovery. We thus tested the hypothesis that intraoperative exposure to soothing music reduces the end-tidal concentration of sevoflurane (ETSevo) necessary to maintain bispectral index (BIS) near 50 during laparoscopic surgery. METHODS: Forty patients, aged 40 -60 yrs, ASA I and II, undergoingdoi:10.1213/ane.0b013e3181733e16 pmid:18635470 fatcat:pyphuzylszb4pjjmq2y7fehdbe
