Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are children aged 1 to 6 years, weighing between 10-30 kg, who are scheduled for elective surgeries requiring airway management.
✕Probably not a fit
Patients with upper airway malformations, recent upper airway surgery, active respiratory illnesses, or anticipated difficult airways may not benefit from this study.

What this trial studies
This observational study aims to evaluate the accuracy of using ultrasonography to measure the epiphyseal diameter of the distal radius as a predictor for the appropriate size of cuffed and uncuffed endotracheal tubes (ETTs) in children aged 1 to 6 years. Traditional methods for determining ETT size rely on age-based formulas, which may not be accurate for all children, especially those with altered growth patterns. By comparing ultrasound measurements to these conventional formulas, the study seeks to establish a more reliable method for airway management in pediatric patients undergoing elective surgery. The findings could enhance the safety and effectiveness of intubation procedures in young children.
Why it matters
Potential benefit: If successful, this approach could lead to more accurate intubation practices, reducing complications associated with incorrect ETT sizing in children.
How similar studies have gone: While the use of ultrasound for airway management is gaining traction, this specific approach of measuring the distal radius to predict ETT size is relatively novel and has not been extensively tested in prior studies.
