About this study

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.

Treatment and study plan

Primary outcomes

  1. Visibility

    Time frame: During regional block (an average of 1 hour)

    The ultrasound visibility of the nerve scored by a 5-step scale.

Secondary outcomes

  1. Additional analgesia

    Time frame: During surgery (an average of 4 hours)

    The need and amount of additional analgetic drugs while the intervention.
