Summary

Ultrasound have been shown to improve the time needed to locate and block nerves in the non obese population. However, its utility is still unknown in the obese population. Ultrasound is known to produce poorer quality images in the obese population. This study aims to find out if it is a better tool for nerve localization compared to the traditional nerve stimulation technique.
