Central neural blockade refers to a medical technique used to interrupt nerve conduction in specific regions of the central nervous system, typically for the purpose of pain management or anesthesia. This procedure involves the administration of anesthetic agents or other medications directly into the central nervous system, often targeting the spinal cord or surrounding areas.
There are primarily two types of central neural blockade:
-
Epidural Anesthesia: An anesthetic is injected into the epidural space surrounding the spinal cord. This technique is commonly used during childbirth and certain surgical procedures to provide pain relief.
-
Spinal Anesthesia: An anesthetic is injected directly into the cerebrospinal fluid (CSF) in the subarachnoid space, which provides rapid and effective anesthesia below the injection site. It is often used for lower abdominal, pelvic, and lower extremity surgeries.
Both methods block the transmission of pain signals from the lower body to the brain, thereby providing effective anesthesia and postoperative pain relief. Central neural blockade is a critical technique in modern anesthesia and pain management practices.
