NCT03291691

Brief Summary

Peripheral nerve blocks can be conducted with ultrasound, electrical nerve stimulation or landmark technique or a combination of this techniques. Whether a regional block should be conducted with a combination of those different possibilities is highly discussed. In this study the investigators want to show the effectiveness of new standard way of combined use of ultrasound and nerve stimulation, they call protective nerve stimulation. According to ethical vote we are conducting an observational study.
