What this trial studies

This observational study will record oxygen saturation continuously during elective airway surgeries performed under general anesthesia with Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE). Investigators will note the time point when oxygen saturation falls below 92% and rescue ventilation is initiated. Clinical, anatomical, and anesthesia-related variables (for example age, severity of subglottic stenosis, anesthesia technique, and apnea duration) will be collected to identify predictors of rescue ventilation. Data will be analyzed to determine which factors are associated with desaturation events requiring intervention.

Who should consider this trial

Good fit: Adults undergoing elective airway surgery for subglottic stenosis under general anesthesia with THRIVE who can provide written informed consent.

Not a fit: Patients who are pediatric, undergoing emergency airway procedures, not managed with THRIVE, or who decline participation are unlikely to benefit from this study's findings.

Why it matters

Potential benefit: If successful, the findings could help clinicians predict and prevent oxygen desaturation, reducing emergency ventilations and improving safety during airway surgeries with THRIVE.

How similar studies have performed: THRIVE has been shown to prolong safe apnea and reduce desaturation in airway procedures, but using patient- and procedure-level predictors to forecast rescue ventilation events is relatively untested.
