Overview
Brief Summary
This study was designed to assess the accuracy of ultrasonographic parameters in combination to clinical parameters in the prediction of difficult airway in pediatric population.
All patients underwent a standard airway examination and sonographic airway assessment preoperatively and the predictive values for difficult airway of these methods were recorded.
Detailed Description
Difficult airway in a pediatric patient is associated with more stresful situation than adults. Therefore, various clinical airways parameters have been investigated in the prediction of difficult airway. Sonographic evaluation to predict difficult airway is still primitive especially in pediatrics. Ultrasonography and clinical parameters have been shown to be used in predicting difficult airway, but there is no study showing which is a better predictor.

Outcomes
Primary Outcomes
Epiglottis skin distance in centimeters.
Time Frame: Five minutes before induction of anesthesia.
The anesthesiologist, who is blind to the patient's preoperative airway evaluation and is experienced user of ultrasonography, measures hyoid bone to skin distance.
Cormack-Lehane Classification
Time Frame: Three minutes after induction of anesthesia.
he anesthesiologist, who is blind to the patient's preoperative airway evaluation and ultrasonographic airway measurements, performs intubation and evaluates the laryngeal view.
Anterior commissure-skin distance in centimeters.
Time Frame: Five minutes before induction of anesthesia
The anesthesiologist, who is blind to the patient's preoperative airway evaluation and is experienced user of ultrasonography, measures anterior commissure to skin distance.
Hyoid bone-skin distance in centimeters.
Time Frame: Five minutes before induction of anesthesia.
The anesthesiologist, who is blind to the patient's preoperative airway evaluation and is experienced user of ultrasonography, measures hyoid bone to skin distance.
