Changes in the electroencephalogram during anaesthesia and their physiological basis.

The use of EEG monitors to assess the level of hypnosis during anaesthesia has become widespread. Anaesthetists, however, do not usually observe the raw EEG data: they generally pay attention only to the Bispectral Index (BIS™) and other indices calculated by EEG monitors. This abstracted information only partially characterizes EEG features. To properly appreciate the availability and reliabil...

The Ageing Brain: Age-dependent changes in the electroencephalogram during propofol and sevoflurane general anaesthesia.

BACKGROUND Anaesthetic drugs act at sites within the brain that undergo profound changes during typical ageing. We postulated that anaesthesia-induced brain dynamics observed in the EEG change with age. METHODS We analysed the EEG in 155 patients aged 18-90 yr who received propofol (n=60) or sevoflurane (n=95) as the primary anaesthetic. The EEG spectrum and coherence were estimated throughou...

The practical value of the electroencephalogram during anaesthesia.

THE INTRODUCTION Of a wide variety of anaesthetac agent,;, the develo'gmcnt of many new and complex tectmlques, and the ever increasing magmtude o_" surgical procedure have so altered the practice of c~inlcal anaesthesia that the tradilaonal concepts of the signs of anaesthette depth are no longer adequate or accurate. The scheme for the clinxcal signs of anaesthesia elaborated by Guedel (1) ba...

Processed electroencephalogram during combined extradural and general anaesthesia.

The processed electroencephalogram (pEEG) was monitored in eight patients undergoing gynaecological laparotomy under combined extradural and nitrous oxide-isoflurane anaesthesia. Pre-incisional mean spectral edge frequency 95 percentile (SEF95) and median frequency (MF) were 11.67 (SD 1.63) Hz and 3.74 (0.24) Hz, respectively. After skin incision, both SEF95 and MF decreased to 6.61 (2.04) Hz a...
