Preoperative Prediction of Difficult Airway in Children

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.

Treatment and study plan

Preoperative Clinical Airway Assessment

Other

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.

Primary outcomes

  1. Difficult Laryngoscopy

    Time frame: Perioperative/Periprocedural

    Difficult laryngoscopy defined as Cormack-Lehane grade III or IV during laryngoscopy at tracheal intubation.

Secondary outcomes

  1. First-Attempt Intubation Success

    Time frame: Perioperative/Periprocedural

    Successful tracheal intubation achieved on the first attempt without the need for additional airway devices or techniques.
