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.

Success rate of peripheral nerve block (PNB) with ultrasound-guided regional anesthesia (UGRA) with and without peripheral nerve stimulation (PNS)
Timeframe: From administration of peripheral nerve block (PNB) until confirmation of successful block onset, assessed up to 60 minutes post-procedure
