About this trial
Peripheral Nerve Blockade (PNB) became reliable with the advent of Ultrasound (US) and Peripheral Nerve Stimulation (PNS).
US offers real-time visualization but has limitations, especially with deep or obscured nerves.
PNS complements US by confirming nerve proximity through motor responses. Combining both may enhance safety and success of nerve blocks. This study compares US-guided blocks with and without PNS in a randomized trial.
