Do EEG-derived indices qCON and qNOX reliably detect loss of consciousness and predict movement during general anaesthesia?
The EEG-derived indices qCON and qNOX can monitor loss of consciousness and predict movement responses during general anaesthesia.
The qCON was able to reliably detect LOC during general anaesthesia with propofol and remifentanil. The qNOX showed significant overlap between movers and non-movers, but it was able to predict whether or not the patient would move as a response to noxious stimulation, although the anaesthetic concentrations were similar.
Jensen et al. (Fri,) studied this question.
