The Diagnostic Efficacy of Ultrasonographic Airway Assessment in Predicting Difficult Laryngoscopy in Pediatric Patients Undergoing Elective Surgery; A Prospective Observational Study

Observational Tanta University · NCT06667921

This study tests if using ultrasound can help doctors predict if it will be hard to place a breathing tube in young children aged 2 to 5 during surgery.

What this trial studies

This observational study evaluates the effectiveness of ultrasonographic airway assessments in predicting difficult laryngoscopy in pediatric patients aged 2 to 5 years undergoing elective surgery. The research focuses on identifying key anatomical features of the upper airway using ultrasound, which may help anesthesiologists anticipate challenges during intubation. By analyzing various ultrasonic parameters, the study aims to establish a reliable method for assessing airway difficulty in children, a population known to face higher risks during anesthesia. The findings could enhance preoperative evaluations and improve patient safety in pediatric anesthesia.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 2 to 5 years who are in ASA physical status I or II and are scheduled for elective surgery requiring general anesthesia.

Not a fit: Patients with maxillofacial trauma, large masses, neck scars, or a history of neck surgery or congenital anomalies may not benefit from this study as difficult intubation is already anticipated in these cases.

Why it matters

Potential benefit: If successful, this study could lead to improved preoperative assessments and safer intubation practices for young children undergoing surgery.

How similar studies have performed: Previous studies have shown success in using ultrasound to predict difficult airways in adults, but this approach in pediatric patients is still being explored and is less established.
