Epidural anesthesia is a type of regional anesthesia that blocks pain in a specific area of the body. It involves injecting a local anesthetic into the epidural space, which is the area surrounding the spinal cord. This technique is commonly used during childbirth and certain surgeries to provide pain relief while allowing the patient to remain awake and alert. The procedure typically involves inserting a thin catheter into the epidural space, allowing for continuous delivery of medication. Epidural anesthesia can effectively reduce pain during labor and delivery, making it a popular choice for many expectant mothers.
