Title: Effects of Desflurane and Isoflurane on EEG
Abstract: Objective To compare the effects of desflurane and isoflurane on EEG. Methods The unpremeditated adult patients of 20ASA grade I~II aged 20~50 years old who were underwent surgery were divided into two groups randomly desflurane (n=10) and isoflurane (n=10). Anesthesia was induced with propofol 2mg/kg and succinycholine 2mg/kg intravenously and maintained with inhalation anesthesia. Two channels EEG monitor was applied. End tidal concentration was adjusted at 0.5, 0.8, 1.0, 1.3 and 1.5 NAC in sequence, was maintained for 10 min before SEF and B1 were recorded. Results There were negative remarkable correlation between either SEF or B1 and MAC in both two groups (r=0.95 and 0.99, p0.01). There was no significant difference between two groups in EEG. Conclusion The EEG might be useful in evaluating anesthesia depth. The effects of desflurane and isoflurane on EEG were similar at equivalent effective concentration.
