However, this relatively simple procedure is widely employed because of the excellent analgesia and muscle relaxation it provides and the absence of respiratory tract irritation and cardiac depression associated with its use in controlled situations.
Spinal anesthesia results from the temporary interruption of nerve transmission after injection of a local anesthetic solution into the subarachnoid space.

The smallest fibers
