Despite comprehensive information about the representation of anaesthe
tic-induced phenomena in the EEG, electroencephalographic monitoring o
f the depth of anaesthesia has not yet become parr of clinical routine
practice. To date, only a few studies have been carried out to invest
igate the question as to the value of computerized EEG for routine ope
rations under realistic clinical conditions. Within the framework of a
multicentre study, the usefulness of the EEG in combination with haem
odynamic parameters for providing indirect signs of sympatho-adrenergi
c stimulation during routine inhalation and balanced anaesthesia with
isoflurane or fentanyl was investigated, Our results show that, with t
he aid of EEG monitoring, stages during anaesthesia that are either to
o deep or too light, can be mole rapidly identified and more quickly c
orrected than is the case with conventional methods. The shorter durat
ion of critical, so-called non-ideal, situations, may be taken as evid
ence that the EEG can, in these situations, contribute towards ensurin
g a properly adapted intervention. Thus, the EEG, used in combination
with haemodynamic parameters, can, without delay, make available infor
mation that facilitates the ''fine-tuning'' of the depth of anaesthesi
