Description of Procedure
With regional anesthesia, you may remain awake, but you will usually be given a sedative to help calm you. Prior to administering the anesthesia:
Your anesthesiologist will inject medication near a cluster of nerves. The selected nerves will be the ones that supply the area of your body that requires surgery.
Types of regional anesthesia include epidural and spinal. Both involve injecting medications in or near the spinal canal.
Another type of regional anesthesia, a peripheral nerve block, is often used for knee, shoulder, or arm surgery. The anesthesia is injected near clusters of nerves that feed the arms or legs. A cervical nerve block is a type of peripheral nerve block for surgeries in the neck or arm.
After Procedure TOP
If local anesthetic is used, you will slowly gain sensation and motion again in the area that was numbed. It can take a few hours or longer before your sensation is completely back to normal. If treating for pain, the pain will return in a few hours, and the relief may take up to 2 weeks. Any pain and discomfort after the procedure can be managed with medications.
How Long Will It Take? TOP
While the regional anesthesia procedure itself takes several minutes or longer, its effects typically last for 2-6 hours.
Will It Hurt? TOP
Depending on whether sedation or local anesthesia is used, you may feel slight pain or tingling with the injection. The anesthetic will prevent you from feeling pain during your surgical procedure. You may feel that your limb may be heavy initially and then light later on.
