If you are having it performed and desire IV sedation they will require you to not eat 8 hours prior to the procedure and only clear liquids up to 4 hours prior. Nothing to eat or drink for the last 4 hours prior. If you are not receiving sedation just don’t eat or drink 2 hours prior please. You will be monitored closely with blood pressure, and blood oxygen monitoring device. Local anesthetic and freezing spray will be used before the actual injection to diminish any discomfort. The physician then locates, under fluoroscopy (X-ray), a specific anatomical target site or location that is near the problem area. Contrast is used to confirm proper placement of medication, typically anesthetic and steroid, is then injected. The Procedure may cause some slight discomfort, however is typically not painful.
Lumbar epidural injections have provided relief for many patients over the course of years. Many patients realize a significant reduction in pain, especially when the injection was received for cases of sciatica. It is important to know that the chances for success and substantial relief are increased when the injections are done in conjunction with a comprehensive physical therapy program. Epidural injections may only be a temporary solution when more conservative options have been exhausted. If the underlying cause of the pain is a significant condition, surgery may be necessary.
With a transforaminal epidural steroid injection (ESI), often referred to as a 'nerve block', the needle is placed alongside the nerve as it exits the spine, and medication is placed into the 'nerve sleeve'. The medication then travels up the sleeve and into the epidural space from the side. This allows for a more concentrated delivery of steroid into one affected area (usually one segment and one side). Transforaminal ESIs can also be modified slightly to allow for more specific coverage of a single nerve and can provide diagnostic benefit, in addition to improved pain and function.
