Official title
Evaluation of the Relationship Between Ultrasonographic Airway Measurements and the PeDiAC Score in Pediatric Patients: A Prospective Observational Study
Overview
This prospective observational study aims to evaluate the relationship between preoperative ultrasonographic airway measurements and the Pediatric Difficult Airway Classification (PeDiAC) score in pediatric patients undergoing general anesthesia. The study will assess whether ultrasound-derived airway parameters are associated with difficult airway characteristics and PeDiAC scores.
Detailed description
Difficult airway management in pediatric patients remains a significant challenge for anesthesiologists and is associated with increased perioperative morbidity. Accurate preoperative identification of children at risk for difficult airway management is essential for improving patient safety and optimizing airway strategies.
Airway ultrasonography has emerged as a noninvasive and bedside imaging modality that allows detailed assessment of upper airway anatomy. Several ultrasonographic airway parameters have been investigated as potential predictors of difficult airway management in children. However, the predictive value of these measurements remains uncertain, and their relationship with standardized pediatric difficult airway assessment tools has not been fully established.
The Pediatric Difficult Airway Classification (PeDiAC) score is a recently developed tool designed to standardize the assessment of difficult airway characteristics in pediatric patients. Evaluating the association between ultrasonographic airway measurements and the PeDiAC score may improve preoperative airway assessment and facilitate the identification of children at increased risk of difficult airway management.
This prospective observational study aims to investigate the relationship between preoperative ultrasonographic airway measurements and the PeDiAC score in pediatric patients undergoing elective surgery under general anesthesia. Preoperative airway ultrasound measurements will be obtained and compared with PeDiAC scores recorded during airway management.
The primary objective is to evaluate the correlation between ultrasonographic airway measurements and the PeDiAC score. Secondary objectives include assessing the predictive value of ultrasonographic measurements for difficult airway management and identifying airway parameters associated with increased airway difficulty in pediatric patients.
Primary outcome measures
- Correlation Between Ultrasonographic Airway Measurements and the PeDiAC Score [Time frame: During airway assessment and endotracheal intubation]
Secondary outcome measures (3)
- Predictive Value of Ultrasonographic Airway Measurements for Difficult Videolaryngoscopy [Time frame: During videolaryngoscopy]
- Relationship Between the PeDiAC Score and Cormack-Lehane Grade [Time frame: During videolaryngoscopy]
- Relationship Between Intubation Time and Ultrasonographic Airway Measurements [Time frame: During endotracheal intubation]
