A clinical trial to study use of ultrasonography to measure airway indices to predict difficult laryngoscopy.

Not yet recruiting

• Conditions: New Technology,

• Registration Number: CTRI/2023/06/053576
• Lead Sponsor: Goa Medical College

Brief Summary

Preanesthetic check-up and clinical assessment of airway will be done.

Consultant Anaesthesiology will perform 2D USG of the airway with patient in supine, sniffing position using ultrasonography linear probe of 6-13MHz.

Distance

Between Skin and hyoid bone (DSHB) and

Between Skin and epiglottis DSE) will be measured in transverse plane.

After complete evaluation general anesthesia is induced with propofol (2-2.5mg/kg), fentanyl (2-4mcg/kg) and vecuronium (0.08-0.1mg/kg).

oAfter verifying adequate neuromuscular relaxation direct laryngoscopy using Macintosh blade will be performed in sniffing position to evaluate Cormack-Lehane grade followed by tracheal intubation.

Patient will be assessed for

Easy laryngoscopy- Grade 1-2a

Difficult laryngoscopy- Grade 2b-4

Number of intubation attempts/ intubation aids/ Need for difficult intubation approach or invasive approach will be noted.
