    Abstract:
    BACKGROUND: We evaluated the effect of landiolol, a novel ultra-short-acting receptor-selective blocker, on bispectral index scale (BIS). METHODS: Ten patients scheduled for off-pump coronary artery bypass (OPCAB) surgery under fast-track cardiac anesthesia were analyzed. Anesthesia was maintained with appropriate additional administration of fentanyl (total dose: 10-15 microg x kg(-1)) and vecuronium under inhalation of a mixture of oxygen, air and sevoflurane (less than 2%). Landiolol was administered continuously for 5 min, when the heart rate (HR) was 80 or more per minute and the BIS values were kept between 40-60. HR, mean arterial pressure (MAP), cardiac index (CI) and BIS values were recorded at 4 time points (after induction of anesthesia, before administration of landiolol, immediately before comple- tion of administration, and 15 minutes after completion of administration). RESULTS: HR decreased significantly by landiolol administration, but there were no significant changes in MAP, CI and BIS. CONCLUSIONS: This study suggests that landiolol does not affect BIS in OPCAB surgery patients under fast-track cardiac anesthesia.
