Comparative Study Clinical Trial
Pocket mobile smartphone system for the point-of-care submandibular ultrasonography.
Focused ultrasonography of the airway may be useful in the prediction of difficult intubation. The wider use of sonography in quantitative airway assessment may depend on the availability of highly portable, inexpensive, and accurate ultrasound systems. Pocket-sized ultrasound devices are emerging as a useful tool for point-of-care ultrasonography. The aim of this study was to evaluate the suprahyoid airway of healthy volunteers using a smartphone-based ultrasound imaging system in comparison with a platform-based machine. ⋯ Mobisante MobiUS system was able to acquire clinically useful images of the suprahyoid airway and muscular architecture in the mouth floor and allowed accurate measurements of linear distances.

Randomized Controlled Trial Comparative Study
A comparison of longitudinal and transverse approaches to ultrasound-guided axillary vein cannulation.
The axillary vein is an easily accessible vessel that can be used for ultrasound-guided central vascular access and offers an alternative to the internal jugular and subclavian veins. The objective of this study was to identify which transducer orientation, longitudinal or transverse, is better for imaging the axillary vein with ultrasound. ⋯ The longitudinal method of visualizing the axillary vein during ultrasound-guided venous access is associated with greater first-attempt success, fewer needle redirections, and a trend of fewer arterial punctures compared with the transverse orientation.
