Evaluation of Difficult Laryngoscopy With Ultrasonography in Pediatric Patients

Intubation; Difficult or Failed Clinical Trial

Official title:
Evaluation of Difficult Laryngoscopy With Ultrasonography in Pediatric Patients

Clinical Trial Summary

Pediatric patients pose challenges in airway management due to anatomical and physiological changes. Using recommended predictive tests for predicting difficult airway can be improved by combining them with ultrasound measurement of the anterior soft tissues of the neck. In this study, the investigators aim to evaluate the ultrasound measurement of anterior neck soft tissues in paediatric patients before anesthesia induction, to anticipate difficult laryngoscopy.

Clinical Trial Description

Eligible participants for this study will be patients aged 2-8 years scheduled for elective surgery under general anesthesia who have provided informed consent. During the preoperative evaluation, demographic data and airway physical examination results (Mallampati score) of the patients will be recorded. Patients who have received preoperative sedation will be positioned supine on the operating table, and ultrasound-guided measurements of soft tissue distances will be taken using a linear probe with a frequency range of 6-13 Hz. The distance between the hyoid bone and skin (DSHB), distance between the vocal cord anterior commissure and skin (DSAC), and distance between the epiglottis and skin (DSE) will be measured. The A/E (Anterior Commissura/Epiglottis) ratio will be calculated after measurements. After standard monitoring and anesthesia induction, difficult laryngoscopy will be evaluated using the Modified Cormack Lehane Score, which grades the visibility of vocal cords and glottic structures. A grade of 3 or 4 on this scale will be considered as difficult laryngoscopy and recorded as such. Tracheal intubation will be performed by an anesthesiologist with at least two years of experience who is unaware of the ultrasound measurements. ;
