• 1 other identifier: VIDIPEDIIDS-25
• Study Type: observational
• Target: 450
• Locations: 1 country
• Sites: 1

Brief Summary

This prospective observational study aims to evaluate three scoring systems (VIDIAC (Video Laryngoscopic Intubation and Difficult Airway Classification), PeDiAC (Pediatric Difficult Airway Classification), and the Intubation Difficulty Scale (IDS)). A total of 450 children undergoing general anesthesia with videolaryngoscopic intubation will be included in the study. Demographic data, intraoperative parameters, and glottic imaging, as well as detailed intubation-related variables such as total intubation time, number of attempts, complications, and subjective intubation ease scores will be recorded.

Conditions

Videolaryngoscopy; Intubation Difficulty Scale; Vidiac Score; Difficult Airway Intubation; Pediatric Anesthesia

Keywords

intubation difficulty scale (IDS); VIDIAC; PeDiAC; Pediatric anesthesia; videolaryngoscopy; airway management

Outcome Measures

Primary Outcomes (2)

• Comparison of VIDIAC, PeDiAC, and IDS Scores in the Evaluation of Difficult Intubation in Children

  For each patient, VIDIAC, PeDiAC, and Intubation Difficulty Scale (IDS) scores will be calculated immediately after tracheal intubation via videolaryngoscopy. These scores will be statistically analyzed to determine the correlation between the number of intubation attempts, intubation time, complications, and subjective intubation ease ratings, in order to identify the scoring system that provides the most reliable assessment of difficult intubation in children.

  Immediately after tracheal intubation

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

  For each patient, VIDIAC, PeDiAC, and Intubation Difficulty Scale (IDS) scores will be calculated immediately after tracheal intubation via videolaryngoscopy. These scores will be statistically analyzed to determine the correlation between the number of intubation attempts, intubation time, complications, and subjective intubation ease ratings, in order to identify the scoring system that provides the most reliable assessment of difficult intubation in children.

Study Arms (1)

Pediatric Patients Undergoing Videolaryngoscopic Intubation

This cohort will include pediatric patients aged 5 to 18 years undergoing elective or emergency surgery under general anesthesia who require tracheal intubation. All patients will be intubated using a C-MAC videolaryngoscope. Each intubation will be evaluated using the VIDIAC, PeDiAC, and Intubation Difficulty Scale (IDS) scoring systems.

Eligibility Criteria

• Age: 5 Years - 18 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

This study will include pediatric patients aged 5 to 18 years who are scheduled for elective or emergency surgery under general anesthesia at Ankara Bilkent City Hospital. All participants will require tracheal intubation performed with a C-MAC videolaryngoscope. Eligible patients will have an ASA physical status classification of I-IV. Written informed consent will be obtained from parents or legal guardians prior to enrollment. Patients undergoing awake fiberoptic intubation, those with a history of tracheal resection, or children younger than 5 years will be excluded.

You may qualify if:

• Pediatric patients between 5 and 18 years of age
• Undergoing general anesthesia for any type of surgical procedure
• ASA physical status classification I to IV
• Written informed consent obtained from parents or legal guardians

You may not qualify if:

• Patients undergoing awake fiberoptic intubation
• History of tracheal resection or reconstruction surgery
• Refusal to participate or absence of informed consent
