What Is a Epidural Steroid Injections?
An intrathecal pump relieves chronic pain. It uses small amounts of medicine applied directly to the intrathecal space (the area surrounding the spinal cord) to prevent pain signals from being perceived by the brain. Pump candidates include people for whom conservative treatments have failed and surgery is not likely to help.
Trial Procedure
After local anesthetic is administered, a catheter is inserted through a needle or small incision into the intrathecal space. This catheter is connected to a temporary pump. It will be used for several days to determine if the system will help the patient. If pain decreases during the trial period, a permanent system may be implanted.
Permanent Implantation
The second procedure is usually performed while the patient is under general anesthesia. The temporary catheter is removed and, through a needle or incision, a permanent catheter is implanted.
