Eligibility

Inclusion criteria

Inclusion criteria: Adults aged 18-60 years, classified as ASA I,II,III scheduled for elective surgeries under general anaesthesia that require endotracheal intubation

Exclusion criteria

Exclusion criteria: Those posted for emergency surgeries Patients with airway abnormalities, airway trauma, or conditions like retrognathis, macroglossia or beard that could interfere with airway assessment Neck scarring, swelling, burns, limited neck mobility, or a history of neck surgery Those not providing written informed consent and other concurrent conditions such as cervical spine trauma, thyroid goitre, tracheal stenosis etc

Design outcomes

Primary

MeasureTime frame
To determine the predictive value of airway ultrasound measurements (combination of skin to epiglottis distance, tongue thickness and hyomental distance) for difficult laryngoscopy with Cormack-Lehane grading. Timepoint: 5mins, 10 mins, 20mins, 30mins

Secondary

MeasureTime frame
To compare the predictive value of airway ultrasound measurements with traditional clinical parameters (modified Mallampati grading, neck circumference and hyomental distance) for difficult laryngoscopy with Cormack-Lehane grading.Timepoint: 5 mins, 10 mins, 20 mins, 30 mins;To compare the predictive value of airway ultrasound measurements with traditional clinical parameters (modified Mallampati grading, neck circumference and hyomental distance) for difficult laryngoscopy with Cormack-Lehane grading.Timepoint: 5 mins, 10 mins, 20 mins, 30 mins
