The study aimed to assess the effectiveness of two EEG-derived indices, qCON and qNOX, in monitoring pediatric patients during surgery under general anesthesia, particularly during induction and recovery periods.
A total of 46 patients aged 1-12 years underwent elective surgeries, with their brain activity monitored using the CONOX system while sevoflurane was used for anesthesia.
Results showed that both indices demonstrated a simultaneous decrease and increase during anesthesia induction and recovery, with qNOX increasing significantly during surgical incision, but neither index strongly correlated with the sevoflurane dosage.
