Comparing three airway difficulty scores for children having video-assisted intubation

A Prospective Observational Study Comparing the VIDIAC, PeDiAC, and Intubation Difficulty Scale (IDS) in Pediatric Patients Aged 5-18 Years Undergoing Tracheal Intubation With Videolaryngoscopy

Observational Ankara City Hospital Bilkent · NCT07245511

We will see if three scoring systems (VIDIAC, PeDiAC, and IDS) describe how hard it is to intubate children aged 5–18 using a videolaryngoscope.

What this trial studies

This is a prospective, observational single-center comparison of three difficult-intubation scoring systems (VIDIAC, PeDiAC, and the Intubation Difficulty Scale) in pediatric patients. The study will enroll 450 children aged 5–18 undergoing elective or emergency surgery under general anesthesia with intubation by C-MAC videolaryngoscope. Researchers will record demographics, intraoperative vitals, glottic images, total intubation time, number of attempts, use of adjuncts, complications, and a subjective ease score to compare how each scale reflects real-world difficulty. All procedures follow routine clinical care and require parental or guardian informed consent prior to participation.

Who should consider this trial

Good fit: Children aged 5–18 undergoing general anesthesia with tracheal intubation using a C-MAC videolaryngoscope whose parent or legal guardian provides written consent.

Not a fit: Children younger than 5, those having awake fiberoptic intubation, those with prior tracheal reconstruction, or patients intubated without a videolaryngoscope are unlikely to benefit from these results.

Why it matters

Potential benefit: If successful, the results could identify a reliable score for pediatric videolaryngoscopic intubation that helps clinicians prepare and reduce airway-related complications.

How similar studies have performed: The IDS is well established in adults and has some pediatric data, but VIDIAC and PeDiAC are newer and direct comparative data in videolaryngoscopic pediatric intubation are limited.
