It consists of the application of anesthetic drugs that block groups of nerves or an area of the spinal cord, with the aim of canceling the pain in a specific part of the body (both legs, lower abdominal area, a forearm, etc).
A good example is shoulder surgery in which the brachial plexus infiltrates the cervical region to fully anesthetize the upper extremity. This technique is performed under ultrasound and conscious sedation of the patient.
Another type of regional anesthesia in spinal anesthesia, in its two variants, intradural or spinal and epidural, allowing us to anesthetize larger areas of the body as the entire lower hemibody.
We use it in surgeries of the lower extremity, hip or knee prosthesis.
