Preoperative Prediction of Difficult Airway in Children

February 10, 2026 updated by: Elif Sule Ozdemir, Diskapi Yildirim Beyazit Education and Research Hospital

Prediction of Difficult Airway in Pediatric Patients Using Preoperative Clinical Parameters

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.
