Anesthesia Induction Scheme for Painless Gastrointestinal Endoscopy Patients Based on Nociceptive Stimulation Monitoring

During gastrointestinal endoscopy, electroencephalogram (EEG) monitoring will be conducted using qCON and qNOX technologies to assess patients\' sedation and analgesia status while they undergo painless gastrointestinal endoscopy. This will be combined with visual assessments (such as cough reflex, respiratory depression, and limb movement) and clinical physiological monitoring (including vital signs and pulse oximetry) to explore and establish a stable and optimal depth of sedation for anesthesia.
