About this trial
This study aims to evaluate the diagnostic accuracy of ultrasonographic airway examination in predicting difficult laryngoscopy in pediatric patients undergoing elective surgery.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Children aged (2-5) years old.
Both sexes.
American Society of Anesthesiology (ASA) physical status I or II.
Undergoing elective surgery under general anaesthesia with endotracheal intubation.
Disqualifiers
Maxillofacial trauma
Large mass.
Scar under the chin.
History of neck surgery or congenital anomalies of the head and neck as difficult intubation is expected in these cases.
Trial population
This prospective observational study will be carried out on 308 children of both genders, American Society of Anesthesiology (ASA) physical status I or II, who will be prepared for elective surgery under general anaesthesia with tracheal intubation.

Trial outcomes
Primary outcomes
1
Accuracy of ultrasound measurement of hyomental distance ratio (HMDR)
Accuracy of ultrasound measurement of hyomental distance ratio (HMDR) in predicting difficult laryngoscopy will be recorded
Time frame
10 minutes till placement of endotracheal tubeSecondary outcomes
1
Accuracy of ultrasound measurement of distance from skin to epiglottis (DSE)
Accuracy of ultrasound measurement of distance from skin to epiglottis (DSE) in predicting difficult laryngoscopy
Time frame

Correlation between the pre-anaesthetic ultrasonographic airway assessment, hyomental distance ratio (HMDR) and distance from skin to epiglottis (DSE)
Correlation between the pre-anaesthetic ultrasonographic airway assessment, hyomental distance ratio (HMDR) and distance from skin to epiglottis (DSE), with the modified Cormack-Lehane grade of direct laryngoscopic view under general anaesthesia. The laryngoscopic view of the patient's airway will be graded using the Modified Cormack and Lehane grading scale; grades 1 and 2 are considered easy laryngoscopy, and grades 3 and 4 are considered difficult laryngoscopy. Grade 1: the whole glottis is visible. Grade 2: part of the cords is visible. Grade 3: only epiglottis is visible. Grade 4: epiglottis isn't visible.
