Epidural steroid injection success rates

This is a rare complication that may occur if a small hole is made in the fibrous sac and does not close up after the needle puncture. These small holes are only made in less than 1% of epidural injections and usually heal on their own. The spinal fluid inside can leak out, and when severe, the brain loses the cushioning effect of the fluid, which causes a severe headache when you sit or stand. These types of headaches occur typically about 2-3 days after the procedure and are positional - they come on when you sit or stand and go away when you lie down. If you do develop a spinal headache, it is OK to treat yourself. As long as you do not feel ill and have no fever and the headache goes away when you lay down, you may treat yourself with 24 hours of bed rest with bathroom privileges while drinking plenty of fluids. This almost always works. If it does not, contact the radiologist who performed the procedure or your referring physician. A procedure (called an epidural blood patch) can be performed in the hospital that has a very high success rate in treating spinal headaches.  

Cervical Epidural Steroid Injections involve injecting a steroid into the epidural space of the cervical spinal canal where irritated nerve roots are located. The injected medications include both a long-lasting steroid and a local anesthetic (Lidocaine, Bupivacaine).
The steroid reduces inflammation and irritation, while the anesthetic interrupts the pain-spasm cycle and nociceptor transmission (Boswell 2007). The medicines spread to the most painful levels of the spine, reducing inflammation and irritation. The entire procedure usually takes less than 15 minutes.

A dural puncture, or "wet tap," is perhaps the most common complication from an ESI. This complication only occurs in to 5 percent of all injections. The result of a dural puncture is usually a spinal headache and nausea. A spinal headache occurs when the puncture in the spinal sac fails to seal itself off. This allows the spinal fluid to continue to leak out and lowers the spinal fluid pressure in the brain. When sitting or standing, the headache and nausea are much worse because the spinal fluid pressure is lower at the top (near your head) than at the bottom of the spine. The headache usually goes away when you lie down with your feet higher than your head.
