BIS Monitoring of the Depth of Anaesthesia in Children

BIS monitoring will be used in the BIS Group patients. The BIS value will be known to the anaesthetist, who will be able to act accordingly.

BIS monitoring will be used in the Non-BIS Group patients. The BIS value will NOT be known to the anaesthetist and will be observed by a trained co-investigator, with subsequent evaluation.

Anaesthetics will be administered in both experimental groups, in order to maintain the required general anaesthesia.
