Anatomical and Ultrasonographic Parameters to Predict Difficult Airway in Pediatrics
Study Details
Study Description
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.

Outcome Measures
Primary Outcome Measures
- Cormack-Lehane Classification [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.
- Epiglottis skin distance in centimeters. [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.
- Hyoid bone-skin distance in centimeters. [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.
- Anterior commissure-skin distance in centimeters. [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.
- Thickness of tongue root in centimeters [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 thickness of tongue root.
Secondary Outcome Measures
- intubation difficulty score (IDS )(between 0 to 7) [During the intubation period]
The anesthesiologist, who performed the intubation, evaluated the intubation difficulty.
- Mallampati classification [The day before surgery]
Evaluated by the anesthesiologist who performs intubation.
- Neck circumference in centimeters. [The day before surgery]
Evaluated by the anesthesiologist who performs intubation.
- Sternomental distance in centimeters. [The day before surgery]
The distance between sternal notch and mentum. Evaluated by the anesthesiologist who performs intubation.
- Thyromental distance in centimeters [The day before surgery]
The distance between thyroid notch and mentum. Evaluated by the anesthesiologist who performs intubation.
- Body mass index (BMI) [The day before surgery]
Weight and height will be combined to report BMI in kg/m^2.Evaluated by the anesthesiologist who performs intubation.
- intubation techniques [During the intubation period]
techniques consisting of classic laryngoscope, videolaryngoscope, stylet, and supraglottic airway device used in intubation
