Abstract
Objective
To compare ultrasonography with computed tomography (CT) for assessment of tracheal diameter as a feasibility study for endotracheal tube selection.

Study design
Prospective study.

Animals
A total of nine Beagle dogs with a median (interquartile range) weight of 7.4 (7.2–7.7) kg.

Methods
Tracheal diameter measurements were obtained at two locations: 1 cm proximal to caudal border of the cricoid cartilage (sublaryngeal; SL) and dorsal to above cranial border of the manubrium (thoracic inlet; TI). For CT, dogs were anesthetized with propofol and sevoflurane, in sternal recumbency, and measurements obtained after controlled ventilation induced apnea and the endotracheal tube cuff was deflated. Transverse diameter, right and left 45º oblique diameters were measured. For ultrasonography, unsedated dogs were standing with slight neck extension, and images obtained in ventrodorsal, 45º right and left oblique ways after expiration. Diameters between the tracheal lumen mucosal borders were measured. The degree of agreement between the tracheal diameters measured at SL and TI locations with CT (TDCT-SL and TDCT-TI) and ultrasonography (TDUS-SL and TDUS-TI) were verified using the Bland-Altman method.

Results
The agreement between the measurements obtained with CT and ultrasonography was revealed by Bland-Altman analyses although ultrasonography tended to slightly underestimate the tracheal diameter.

Conclusions And Clinical Relevance
Ultrasonography can be applied for tracheal diameter measurement. Although further studies are required, an endotracheal tube selection method, using ultrasonography, could be proposed.
