Summary
A standardized tetanic stimulation is applied to patients under propofol-remifentanil TCI, in
a cross-over fashion, at two different levels of anesthesia monitored by the BIS: BIS 25 and
BIS 55. Remifentanil target remains constant during the whole study period (1 ng/ml).
Pupillary reflex dilation is recorded after each stimulation.
