The spermatic cord block is a nerve block that works much the same way a nerve block for back pain works. Lets say you have something that is causing the pain, and the nerves tell your spine that theres pain there, Geltzeiler explains.
Ultrasound guided sciatic nerve block in the popliteal region is considered a BASIC skill level block because the nerve is easily visualized. Both In Plane (IP) and Out of Plane (OOP) approaches are available. The OOP approach is commonly used for single shot and catheter placement.
