Is cerebral autoregulation preserved in children anesthetised by sevoflurane?: A-562

摘要: Materials and Methods: ASA 1 children undergoing elective urological surgery were recruited, each receiving sevoflurane at 0.5, 1.0 and 1.5 MAC in random order. Analgesia was provided by caudal anesthesia using 0.25% bupivacaine without epinephrine. The middle cerebral artery flow velocities before (F1), during (F2) and after (F3) ipsilateral carotid artery compression were recorded. THRR is calculated by dividing F3 by F1.Results and Discussions: To date 10 male children aged between 1.4 to 3.2 yrs (1.5±0.7) have been recruited. Results are presented as means (SD) in the following Table.
