The administration of a local anesthetic in the subarachnoid space acts on the spinal roots causing reversible blockage of these nerves. It is a classic technique that has been refined over time and expanded in its practical applications. The development of new drugs and special techniques has been crucial and has greatly influenced the use of spinal anesthesia and its indications.
