qCON/qNOX-guided anesthesia for thyroidectomy

The Effect of qCON/qNOX-Guided Anesthesia Using the Conox Monitor on Clinical Outcomes in Patients Undergoing Thyroidectomy Surgery

Not applicable Interventional Kayseri City Hospital · NCT07445659

This trial will test whether using the Conox qCON/qNOX monitor during thyroid surgery reduces intraoperative opioid use and speeds recovery for adults having a thyroidectomy.

What this trial studies

Adults undergoing thyroidectomy at Kayseri City Hospital will receive either Conox-guided anesthesia with qCON/qNOX monitoring or standard anesthesia management, with maintenance by inhalational agents and opioids and no additional neuromuscular blockers after induction. The primary outcome is intraoperative opioid consumption, with secondary outcomes including recovery time, postoperative agitation rates, and pain scores. Investigators will record qCON and qNOX indices and correlate them with conventional hemodynamic parameters to explore their relationship with nociception and anesthetic depth. Standard eligibility rules apply (age 18–70, ASA I–II) and EEG electrode placement is required unless prevented by skin lesions.

Who should consider this trial

Good fit: Adults aged 18–70 with ASA physical status I–II scheduled for thyroidectomy who can have EEG electrodes placed and can give informed consent are the ideal candidates.

Not a fit: Patients with skin lesions that prevent EEG placement, preexisting neurological disorders, an anticipated difficult airway, or those outside the age/ASA criteria are unlikely to receive benefit from this protocol.

Why it matters

Potential benefit: If successful, Conox-guided anesthesia could reduce opioid use during surgery and shorten recovery and discomfort after thyroidectomy.

How similar studies have performed: Some prior studies of nociception monitoring have shown reduced intraoperative opioid use and better hemodynamic control, but results are mixed and the specific use of qCON/qNOX in thyroidectomy is relatively novel.
