Abstract:
Objective To study the effects of arterial carbon dioxide tension(PaCO 2)on the quantitative electroencephalogram(qEEG)during isoflurane anesthesia Methods Fifteen ASA grade Ⅰ Ⅱ patients,scheduled for intraspinal or transspphenoidal surgery, were studied during 1MAC steady state isoflurane anesthesia qEEG were recorded continuously, while PaCO 2 approached approximately 26 5 mmHg, 35 2mmHg or 45 7 mmHg respectively randomly by regulating the minute volume Results Hypocapnia caused significant increases in all power bands (P
