Conox-guided anesthesia for children having adenotonsillectomy

Official title: A Randomized Controlled Trial Evaluating the Effect of qCON/qNOX-Guided Anesthesia on Clinical Outcomes in Pediatric Adenotonsillectomy

Run by Kayseri City Hospital · NCT07577154 · Data updated 2026-11-12

This trial will test whether using Conox (qCON/qNOX) monitoring during anesthesia helps children aged 3-12 having adenotonsillectomy use less opioid and recover more smoothly after surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are children 3-12 years old with ASA physical status I-II scheduled for elective adenotonsillectomy whose parents or guardians can provide written informed consent and who have no acute infection or systemic disease.

Probably not a fit

Children with neurological disease (including epilepsy), previous pharyngeal surgery, BMI above the 95th percentile, skin or anatomical issues preventing EEG electrode placement, prior anesthesia complications, or lack of consent are excluded and unlikely to benefit from this protocol.

What this trial studies

This randomized controlled trial will enroll 128 children aged 3-12 with ASA I-II who are scheduled for elective adenotonsillectomy and randomize them to Conox-guided anesthesia or standard monitoring. Conox is a non-invasive EEG device that provides qCON (hypnosis) and qNOX (nociception) indices to guide anesthetic and analgesic dosing alongside routine monitoring. All participants will receive a standardized anesthesia protocol (propofol, fentanyl, rocuronium induction; sevoflurane maintenance) and the primary outcome is total intraoperative opioid consumption. Secondary outcomes include emergence time, extubation time, postoperative agitation, pain scores, and correlations between qCON/qNOX values and hemodynamic measures.

Why it matters

Potential benefit: If successful, Conox-guided anesthesia could reduce intraoperative opioid use and improve early recovery and comfort after adenotonsillectomy in children.

How similar studies have gone: EEG-guided anesthesia (for example BIS) has shown some benefits in adults, but use of Conox (qCON/qNOX) in pediatric adenotonsillectomy is relatively novel with limited prior pediatric data.
