Background: Obtaining airway security holds the utmost importance in anesthesia. Specific predictive tests or findings for difficult airway are not defined for various pediatric age groups. Anthropometric measurements are defined parallel to percentile curves in different age groups. Aim: The aim of this study is to find out the value of body mass index and anthropometric measurements in prediction of difficult laryngoscopy in children by comparing to direct laryngoscopic evaluation of Cormack-Lehane test. Methods: Following institutional ethics committee approval and informed consent of parents of 108 patients (ages 0-3years), undergoing elective surgery were included in this study. Weight, height, body mass index and head circumference of the patients were measured and percentiles were recorded, prior to induction. Following standard anesthesia induction with thiopental all patients received 0,6 mg.kg-1 rocuronium intravenously. After sufficient time for neuromuscular relaxation laryngoscopy performed and Cormack-Lehane scores recorded. All recorded parameters were compared with Cormack-Lehane scores.

Difficult laryngoscopy classification using Cormack-LehaneGrade Assessment of difficult laryngoscopy at the time of the airway management procedure.
Classified as Grade I-visualization of entire laryngeal aperture, grade II-visualization of only posterior commissure of laryngeal aperture, grade III-visualization of only epiglottis, grade IV-visualization of just the soft palate.
Time frame: immediate
Head circumference measured in cm with a measuring tape.
Head circumference were taken at the level above eyebrows and ears and measured in cm with a measuring tape.
Time frame: immediate
Weight measured in kilogram with electronic scale.
Weight measured using electronic scale (0-20 kg) while undressed and without diapers .
Time frame: immediate
Height measured in cm with infantometer.
Height measured using a portable infantometer (0-100 cm) while the child was in supine position.
Time frame: immediate
BMI was calculated as kg/m2.
BMI measured using a weight/height2 formul
Time frame: immediate
Percentage values measured in % with percentile tables.
Percentage (%) values using from the percentile tables of Turkish children were determined after the head circumference (cm), height (cm), weight (kg) and BMI (kg/m2) values of all pediatric cases were determined as described above.
