What this Trial Is About
Impedance can have an impact on nerve block during loco-regional anesthesia, particularly when using techniques such as nerve stimulation or ultrasound guidance to locate and block specific nerves. Impedance refers to the resistance to electrical current flow within tissue, and it can affect the ability to stimulate nerves or visualize them using ultrasound. The aim of this research is to assess the impedance across different tissue type during an axillary peripheral nerve block (skin, fat, fascia, muscle, nerve). The results of this study would help clinicians performing nerve block to enhance the precision of needle placement, thus increase the success rate of nerve block and reduce adverse events such as intraneural or intravascular injections.
