Knowledge For Nerve stimulator needle

September 18,2023

In general, 22-gauge insulated needles are probably used most commonly for single-shot peripheral nerve blocks.

With needle size, a balance must be sought between patient comfort and bending of the needle as it punctures through the skin.


Stimulating Peripheral Nerve Block Needle is designed to help increase overall block success by enhancing needle control and maneuverability during needle positioning. Designed with less traumatic B-bevel tip for optimal balance between tactile feedback and penetration.


A peripheral nerve stimulator, also known as a train-of-four monitor, is used to assess neuromuscular transmission when neuromuscular blocking agents (NMBAs) are given to block musculoskeletal activity.


During the permanent implantation procedure, the generator is placed underneath the skin and the trial electrodes are replaced with sterile electrodes. Unlike the trial electrodes, these will be anchored by sutures to minimize movement.


The peripheral nerve stimulation can be performed either in the ulnar, facial, or posterior tibial nerve. The ulnar nerve in the wrist is the preferred site, but if gross anasarca is present, the facial nerve is then usually the site of second choice. Spinal cord stimulation and peripheral nerve field stimulation are considered generally safe, with the potential risks mainly related to the surgical procedures required for a trial period or long-term therapy.
