An observational study in Pediatric Anesthesia and Difficult Laryngoscopy, sponsored by Diskapi Yildirim Beyazit Education and Research Hospital. Recruiting at 1 site in Turkey (Türkiye). Open to participants aged 1 Day to 12 Years. Per ClinicalTrials.gov, last updated 2026-02-11.
Sponsored by Diskapi Yildirim Beyazit Education and Research Hospital · Observational
This prospective observational study aims to evaluate the predictive value of preoperative clinical airway assessment parameters for difficult airway management in pediatric patients undergoing elective surgery under general anesthesia. Preoperative clinical measurements and bedside airway tests will be recorded, and their association with intraoperative airway outcomes, including difficult laryngoscopy and difficult intubation, will be analyzed. Difficult laryngoscopy will be defined as Cormack-Lehane grade III-IV, while secondary outcomes will include difficult intubation, difficult mask ventilation, and airway-related complications. The study seeks to identify clinically applicable predictors and improve preoperative risk stratification for pediatric airway management. The findings may contribute to safer anesthetic practice in children by facilitating early identification of patients at increased airway risk.
Diskapi Yildirim Beyazit Education and Research Hospital is the lead sponsor of 71 studies on the registry; 12 are open to participants now.
Counted across the registry records on this site, refreshed daily.
The study population consists of pediatric patients aged 0 to 12 years who are scheduled for elective surgery under general anesthesia requiring endotracheal intubation.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Preoperative clinical airway assessment including bedside airway examination and anthropometric measurements performed as part of routine anesthetic evaluation, without any additional intervention beyond standard clinical practice.
Difficult Laryngoscopy
Difficult laryngoscopy defined as Cormack-Lehane grade III or IV during laryngoscopy at tracheal intubation.
Time frame: Perioperative/Periprocedural
First-Attempt Intubation Success
Successful tracheal intubation achieved on the first attempt without the need for additional airway devices or techniques.
Time frame: Perioperative/Periprocedural
Started Feb 2026 (actual). Primary completion is estimated for May 2027, 15 months after the start.
