Anaes Vivas · Ultrasound-guided peripheral nerve blocks
Equipment viva — the ultrasound machine and the regional needle
An equipment viva on the US machine — the probe selection (linear/high-frequency for superficial, curvilinear/low-frequency for deep), the needle design (echogenic tip, the in-plane vs out-of-plane approach), and the principles of the image optimisation.
