We assessed the visibility of peripheral nerves while ultrasound guided blockades with a novel scoring system to evaluate differences in visibility of different nerves.

Full description

We assessed the visibility of peripheral nerves while ultrasound guided blockades with a novel scoring system to evaluate differences in visibility of different nerves.

VIS(visibility) 1 easy identification and instant visualisation of all structures VIS 2 identification and visualisation of all structures after some corrections VIS 3 identification and visualisation of structures only unsure VIS 4 identification and visualisation of all structures impossible VIS 5 no structures seen. We amended a sub-project in which assessed the visibility in protective nerve stimulated nerve blocks in 46 patients.

Enrollment: 1,200 patients
