A regional nerve block is administered using 20 to 40 cc of local anesthetic (such as a slow-release dose of bupivacaine) to “freeze” the area being operated on. The nerve block is long-lasting and works for approximately 12-18 hours after surgery. This means that patients can go home and sleep comfortably in their own beds. In addition to managing the pain that is typical right after a surgical procedure, local and regional anesthetics help get you functional much faster than undergoing a general anesthesia to control your surgical pain. Because exercise and eventually physical therapy will be an important part of a successful outcome, engaging in basic movement early on gives you a head start on your recovery. As the nerve block gradually wears off, oral pain medications may be used to manage any discomfort.
