Discrepancy of Airway Assessment for Intubation Among Thai Population Using Fingerbreadths as Substitute for Centimetres
Sponsor: Prince of Songkla University
Summary
Hand-dimensions of 64 airway assessment personnel were measured by one investigator using a vernier caliper. These personnel assessed the thyromental distance and inter-incisor gap of 15 pseudo-patients in a fully crossed design following normal practice. They then measured these parameters using a vernier caliper. Inter-assessor variability using the same pseudo-patient was then compared between measurements based on raw fingerbreadths, fingerbreadths adjusted for hand size, and vernier caliper.

Interventions
the caliper venier will be used to measure the airway.
the vernier calipers were applied with only light pressure so that the soft tissue of the hand was not indented. Each measurement was made three times and the mean dimension calculated.
