How does Lidocaine work? Lidocaine is a bioactive molecule that works to block the excitatory conduction of the spinal nerves which causes them to stay in a depolarized state, hindering impulse transmission. Below is a video created by a nursing student from Mountain State that illustrates how lidocaine works. Lidocaine and the Body.
Injection of medications similar to lidocaine are used to block the nerves for several hours. This type of anesthesia could be anaxillary block (only the arm is asleep) or a wrist block (only the hand is asleep). The surgery can also be performed by simply injecting lidocaine around the area of the incision.
